People are just not doing it anymore, especially the young. Who‟s responsible? Actually, it‟s more like, What is responsible? The Internet, of course, and everything that comes with it —Facebook, Twitter (微博). You can write your own list.There‟s been a warning about the imminent death of literate civilization for a long time. In the 20th century, first it was the movies, then radio, then television that seemed to spell doom for the written world. None did. Reading survived; in fact it not only survived, it has flourished. The world is more literate than ever before —there are more and more readers, and more and more books.The fact that we often get our reading material online today is not something we should worry over. The electronic and digital revolution of the last two decades has arguably shown the way forward for reading and for writing. Take the arrival of e-book readers as an example. Devices like Kindle make reading more convenient and are a lot more environmentally friendly than the traditional paper book.As technology makes new ways of writing possible, new ways of reading are possible. Interconnectivity allows for the possibility of a reading experience that was barely imaginable before. Where traditional books had to make do with photographs and illustrations, an e-book can provide readers with an unlimited number of links: to texts, pictures, and videos. In the future, the way people write novels, history, and philosophy will resemble nothing seen in the past.On the other hand, there is the danger of trivialization. One Twitter group is offering its followers single-sentence-long “digests” of the great novels. War and Peace in a sentence? You must be joking. We should fear the fragmentation of reading. There is the danger that the high-speed connectivity of the Internet will reduce our attention span —that we will be incapable of reading anything of length or which requires deep concentration.In such a fast-changing world, in which reality seems to be remade each day, we need the ability to focus and understand what is happening to us. This has always been the function of literature and we should be careful not to let it disappear. Our society needs to be able to imagine the possibility of someone utterly in tune with modern technology but able to make sense of a dynamic, confusing world.In the 15th century, Johannes Guttenberg‟s invention of the printing press in Europe had a huge impact on civilization. Once upon a time the physical book was a challenging thing. We should remember this before we assume that technology is out to destroy traditional culture.81. Which of the following paragraphs briefly reviews the historical challenges for reading?A . Paragraph One .B. Paragraph Two. C. Paragraph Three .D. Paragraph Four.82. The following are all cited as advantages of e-books EXCEPTA. multimodal contentB. environmental friendliness.C. convenience for readers.D. imaginative design.83. Which of the following can best describe how the author feels toward single-sentence-long novels?A. IronicB. WorriedC. Sarcastic .D. Doubtful.84. According to the passage, people need knowledge of modern technology and to survive in thefast-changing society.A. good judgmentB. high sensitivity C good imagination D. the ability to focus85. What is the main idea of the passage?A. Technology pushes the way forward for reading and writing.B. Interconnectivity is a feature of new reading experience.C. Technology is an opportunity and a challenge for traditional reading.D. Technology offers a greater variety of reading practice.TEXT CThese days lots of young Japanese do omiai, literally, “meet and look.” Many of them do so willingly. In today‟s prosperous and increasingly conservative Japan, the traditional omiai kekkon, or arranged marriage, is thriving.But there is a difference. In the original omiai, the young Japanese couldn‟t reject the partner chosen by his parents and their middleman. After World War II, many Japanese abandoned the arranged marriage as part of their rush to adopt the more democratic ways of their American conquerors. The Western ren’ai kekkon, or love marriage, became popular; Japanese began picking their own mates by dating and falling in love.But the Western way was often found wanting in an important respect: it didn‟t necessarily produce a partner of the right economic, social, and educational qualifications. “Today‟s young people are quite calculating,” says Chieko Akiyama, a social commentator.What seems to be happening now is a repetition of a familiar process in the country‟s history, the “Japanization” of an adopted foreign practice. The Western ideal of marrying for love is accommodated in a new omiai in which both parties are free to reject the match. “Omiai is evolving into a sort of stylized introduction,” Mrs. Akiyama says.Many young Japanese now date in their early twenties, but with no thought of marriage. When they reach the age —in the middle twenties for women, the late twenties for men —they increasingly turn toomiai. Some studies suggest that as many as 40% of marriages each year are omiai kekkon. It‟s hard to be sure, say those who study the matter, because many Japanese couples, when polled, describe their marriage as a love match even if it was arranged.These days, doing omiai often means going to a computer matching service rather than to a nakodo. The nakodo of tradition was an old woman who knew all the kids in the neighbourhood and went around trying to pair them off by speaking to their parents; a successful match would bring her a wedding invitation and a gift of money. But Japanese today find it‟s less awkward to reject a proposed partner if the nakodo is a computer.Japan has about five hundred computer matching services. Some big companies, including Mitsubishi, run one for their employees. At a typical commercial service, an applicant pays $80 to $125 to have his or her personal data stored in the computer for two years and $200 or so more if a marriage results. The stored information includes some obvious items, like education and hobbies, and some not-so-obvious ones, like whether a person is the oldest child. (First sons, and to some extent first daughter, face an obligation of caring for elderly parents.)91. According to the passage, today‟s young Japanese preferA. a traditional arranged marriage.B. a new type of arranged marriage.C. a Western love marriage.D. a more Westernized love marriage.92. Which of the following statements is CORRECT?A. A Western love marriage tends to miss some Japanese values.B. Less attention is paid to the partner‟s qualification in arranged marriages.C. Young Japanese would often calculate their partner‟s wealth.D. A new arranged marriage is a repetition of the older type.93. According to the passage, the figure 40% (Paragraph Five) is uncertain becauseA. there has been a big increase in the number of arranged marriages.B. Western love marriage still remains popular among young Japanese.C. young Japanese start dating very early in their life in a Western tradition.D. the tendency for arranged marriages could be stronger than is indicated.94. One of the big differences between a traditional nakodo and its contemporary version lies in the wayA. wedding gifts are presented.B. a proposed partner is refused.C. formalities are arranged.D. the middleman/woman is chosen.95. What is the purpose of the last paragraph?A. To tell the differences between an old and modern nakodo.B. To provide some examples for the traditional nakodo.C. To offer more details of the computerized nakodo.D. To sum up the main ideas and provide a conclusion.TEXT DCordia Harrington was tired of standing up all day and smelling like French fries at night. She owned and operated three McDonald‟s shops in Illinois, but as a divorced mother of three boys, she yearned for a business that would provide for her children and let her spend more time with them.Her lucky moment came, strangely enough, after she was nominated in 1992 to be on the McDonald‟s bun committee. “The company picked me up in a corporate jet to see bakeries around the world,” she recalls. “Every time I went to a meeting, I love it. This was global!”The experience opened her eyes to business possibilities. When McDonald‟s decided it wanted a new bun supplier, Harrington became determined to win the contract, even though she had no experience running a bakery.Harrington studied the bakery business and made sure she was never off executives’ radar. “If you have a dream, you can‟t wait for people to call you,” she says. “So I‟d visit a mill and send them photos of myself in a baker‟s hat and jacket, holding a sign that say …I want to be your baker.‟”After four years and 32 interviews, her persistence paid off.Harrington sealed the deal with a handshake, sold her shops, and borrowed $13.5 million. She was ready to build the fastest, most automated bakery in the world.The Tennessee Bun Company opened ahead of schedule in 1997, in time for a slump in U.S. fast-food sales for McDonald‟s. Before Harrington knew it, she was down to her last $20,000, not enough to cover payroll. And her agreement with McDonald‟s required that she sell exclusively to the company. “I cried myself to sleep many nights,” she recalls. “I really did think, I am going to go bankrupt.”But Harrington worked out an agreement to supply Pepperidge Farm as well. “McDonald‟s could see a benefit if our production went up and prices went down, and no benefit if we went out of business,” she says. “That deal saved us.”Over the next eight years, Harrington branched out even more: She started her own trucking business, added a cold-storage company, and now has three bakeries producing fresh buns and frozen dough —all now known as the Bun Companies. Speed is still a priority: It takes 11 people at the main bakery to turn out 60,000 buns an hour for clients across 40 states, South America, and the Caribbean.Grateful for the breaks she‟s had, Harrington is passionate about providing opportunities to all 230 employees. “Financial success is the most fun when you can give it away,” she says.The current economy is challenging. Some of her clients‟sales have declined, but she‟s found new clients and improved efficiencies to help sustain the company‟s double-digit growth.Cordia Harrington doesn‟t have to stand on her feet all day anymore. Two of her three sons now work for her. And she‟s remarried —her husband, Tom, is now her CFO.“This is more than a job,” says Harrington. “It‟s a mission. I‟m always thinking. How can we best serve our employees? If we support them, they‟ll do their best to look after our clients. That‟s how it works here.”96. According to the passage, which of the following was most significant in her early career?A. Her nomination on the McDonald‟s bun committee.B Her travel an the visits to bakeries around the world.C. A business contract with local bun suppliers.D. The interviews and experience in running a bakery.97. “Harrington…made sure she was never off executives’ radar” (Paragraph Four) means that sheA. herself wanted to be a company executive.B. meant to hire executives to run the business.C. meant to keep her management knowledge and skills.D. focused on the management of the bakery business.98. How did she survive the crisis at the start of her bakery business?A. By supplying buns for another company.B. By opening her bun company ahead of schedule.C. By keeping supplies up for McDonald‟s.D. By making a new agreement with McDonald‟s.99. Which of the following statements is INCORRECT in describing her current business?A. It is fast growing.B. It is diversified.C. Its clients are all local.D. It is more efficient.100. According to the passage, which of the following is fundamental to Harrington‟s success?A. Efficiency and love for the family.B. Perseverance and concern for employees.C. Business expansion and family support.D. Opportunities and speed.完形填空部分31-35 BDACB 36-40 DACBD 41-45 CABDA 46-50 CBADB阅读部分81-85 BDBAC 85-90 ACADB 91-95 BADDC 96-100 BCACB2012年英语专业四级考试真题From 2007 to 2010,American households lost $l1 trillion in real estate,savings, and stocks More than half of all U.S.workers either lost their jobs or were forced to take cuts in hours or pay during the recession.The worst may be behind them now, but the shocking losses of the past few years have reshaped nearly every facet of their lives—how they live,work,and spend—even the way they think about the future.For Cindy, the recession began when her husband was relocated to Rhinelander, Wisconsin.by his company forcing the family to move in a hurry.The couple bought a new house but were unable to sell their two-bedroom home in Big Lake,Minnesota.With two mortgages(抵押借款) and two young children to care for, Cindy couldn't imagine how to stretch her husband's paycheck to keep her family fed.Then she stumbled upon an online community called Blotanical,a forum for gardeners,many with an interest in sustainability.“The more I read and discussed these practices,the more I realized this would help not only our budget but also our health,”she says.Cindy admits that before the recession,she was a city girl with no interest in growing her own dinner.“I grew flowers mostly—I didn‟t think about plants that weren‟t visually interesting." But to stretch her budget,she began putting in vegetables and fruit—everything from strawberry beds to apple trees—and as her first seedlings grew,her spirits lifted.She no longer thinks of gardening and making her own jams as just a money saver;they‟re a genuine pleasure.“It‟s brought us closer together as a family, too,”she says.Her kids voluntarily pitch in with(主动帮助)the garden work,and the family cooks together instead of eating out.The food tastes better —it's fresher and organic —and the garden handily fulfills its original purpose:cost cutting.Now she spends about $200 to $300 a month on groceries.less than half of the $650 a month that she used to lay out.After discovering how resourceful she can be in tough times,Cindy is no longer easily discouraged.“It mak es me feel proud to be able to say I made it myself,”she says.“I feel accomplished,and I'm more confident about attempting things I've never done before." Now she avoids convenience stores and has begun learning to knit,quilt,and make her own soap."I don't think I would have ever begun this journey if it weren‟t for the recession,”she says.“I have a feeling that from now on,it will affect my family‟s health and happiness for the better."86.We learn from the first paragraph that the recessionA.affected Americans in certain occupations.B.had great impact on Americans‟work and life.C.had only brought huge losses in savings and stocks.D.is over with some of the losses recovered.87.What made the family's financial situation even worse was that theyA.moved to Rhinelander in a hurry.B.had two children to raise.C.didn't know anyone in Rhinelander.D.couldn't sell their home in Big Lake.88.Which of the following statements is CORRECT?A.Cindy had seen the benefits of gardening in a different wayB.Cindy had developed a hobby of gardening before the recessionC.Cindy had already had a keen interest in sustainability.D.Cindy had already planned to meet the gardeners.89.In addition, Cindy views gardening as a genuine pleasure because gardeningA.helped her cut living costs almost by half.B.enabled her to make her own jams.C.built up family ties and kids‟enthusiasm.D.enabled her to know more about plants.90.What does Cindy think of the difficult times she has gone through?A.It gave the couple and their kids a tough lesson.B.It gave her confidence and optimism.C.It would come again and affect the family.D.It left a lasting psychological impact on the family.。

硬盘分区及大小调整(Hard disk partition and size adjustment)The size of the partition is shown as an integer calculation: the desired size is G,The formula for calculating partition size M: M= (G-1)*4+1024*GExample: the partition of 30GB is (30-1) *4+1024*30=30836MBActive (active area), Primary (primary partition), Logical (logical partition), Extended (extended zone), Type (format)Do not data, use Paragon partition magager partition; need data, can use DiskGen to restore partition table under DOSI. Basic knowledge of partitioning1. primary partition, extended partition, logical partitionThe main partition of a hard disk, that is, the hard disk partition that contains the files and data necessary to start the operating system. The hard disk must have a primary partition to install the operating system on the hard disk.Extended partitions, that is, partitions other than the primary partition, cannot be used directly, and must be partitioned into several logical partitions. Logical partitioning, that is, we usually see D, E, F and other disks in the operating system.2. partition formatDifferent operating system formats are not the same, the current Windows partition format used mainly FAT16, FAT32, NTFS3. zoning principleNo matter which partition software is used, you should follow the following order when you build a partition on your new hard drive: build a primary partition, set up an extended partition, set up a logical partition, activate the main partition, and format all partitions.Get started: learn how to partition and resize a hard disk driveTwo, partitionThe partition function interface also has three options, namely, setting up the main partition; setting up an extended partition; and setting up a logical partition on the extended partition.Three, use magic to adjust the partitionPartition Magic, referred to as PQC is the most prone to capacity crisis following the partition, in order to increase the capacity of C for example: to increase the capacity of the C, naturally reduce the capacity of other partitions. Assuming that the remaining space nowD disc 1GB, 3GB free spaceE disk, now to the two partitions in the 4GB space to the C drive, then use PQ DOS 8 version of the operation, the remaining space E disk to the D disk, and then by the D disk to disk.Specific operations are as follows: after entering the PQ main interface, right-click the E disk, select the right-click menu "Resize/Move" (change / move) (Figure 6).Introduction: learning to partition and resize a hard disk (Figure six)Enter the "Resize/Move Partition" (change / mobile space) after the window, in the "Free Space Before" (before adjusting the remaining space bar input) to make the E disc vacated space, the value is less than or equal to the maximum value of the residual space of E disk (Figure 7).Introduction: learning to partition and resize a hard disk (Figure seven)After inputting the space capacity value that needs to be vacated, click the "OK" button to return to the main interface, then you will find that there is a "gap" between D and E, which is the "gift" of the E disk to the D disk.Right click on "D disk" and select "Resize/Move"". Enter the D disk "Resize/Move Partition" window, "Free Space After" will be the first of the figures from the original XXX (also known as "Free Space Before E disk") is amended as "0", so even if the E disk "gift" closed down. Then in the "Free Space Before" column, enter the space value for the D disk to be vacated. Finally, click the "OK" key to confirm (Figure 8).Introduction: learning to partition and resize a hard disk(figure eight)Now C and D have a relatively large "blank area", this is the final Teng to space C. Right click on the drive, and then select "Resize/Move", "Resize/Move Partition" in C window "Free Space After" number is set to "0" to save the settings, D, E to C a gift all. Click on the "Apply" button in the lower right corner of the main screen and confirm, and PQ begins a formal adjustment.Note: Although PQ can adjust the partition size, lossless format, but for data safety, the best can be important data backup before operation, at least for disk scanning and disk fragmentation on the hard disk in operation before finishing work, so as to avoid data loss; when using PQ instead of non normal exit system or suddenly shut down, it is very easy to cause the loss of data in the physical partition, and cause damage to the hard disk.About types of disk partitions, primary disk partitions, extended disk partitions, and logical disk partitions.Early DOS and later Windows divided the disk partition into two main classes, the main disk partition and the extended disk partition. There was at least one primary disk partition on a hard disk, otherwise it would not boot the operating system.In addition to the main disk partition, the rest of the space needs to be partitioned into an extended disk partition, and then divided into logical disk partitions on the extended disk partition.Extended disk partitions are not able to boot the operating system directly, and a hard disk can only partition one extended disk partition. For example, if a hard disk is partitioned into four partitions, C, D, E, and F, then C is the primary disk partition, and D, E, and F are logical disk partitions,These three logical partitions are built on the extended disk partition of this hard disk.。

a rXiv:h ep-ph/941249v114Jan1994UM–P-94/01OZ-94/01Calculating Fragmentation Functions from DefinitionsJ.P.Ma Recearch Center for High Energy Physics School of Physics University of Melbourne Parkville,Victoria 3052Australia AbstractRecently it has been shown[1,2,3,4]that the fragmentation functions for a hadron as a bound-state of two heavy quarks can be calculated perturbatively.The reason such cal-culations are possible is that the bound-states can be described well by the nonrelativstic wavefunctions and hence the effect of long distance in the fragmentaion can be factorized into the wavefunction,expressed through the radial wavefunction at the origin.Although it is realized[2,4]that the fragmentaion functions are universal,the fragmentation func-tions calculated in these works are extracted from specific processes.It should be noted that in QCD the definitions of the fragmentaion functions(or decay functions)are already given by Collins and Soper[5]and these functions should be universal and independent of pocesses.The so called factorization thorem is based on such definitions(for the factoriza-tion theorem see[6]and references cited there).It is interesting to calculate fragmentation functions directly from these defintions and to compare those obtained previously.On the other hand,it is also convenient to work with the defintions for calculating the high order corrections.In this letter we will calculate fragmentation functions from the definitions.To give the definitions for a fragmentaion function it is convenient to work in the light-cone coordinate system.In this coordinate system a4-vector p is expressed as pµ= (p+,p−,p T),with p+=(p0+p3)/√ 2.Introducing a vector n with nµ=(0,1,0T),the fragmentation functions for a spinless hadron H are defined as[5]:D H/Q(z)=z3Tr color132πk+ dx−e−iP+x−/z<0|G b,+ν(0){¯P exp{−ig s ∞0dλn·G(λnµ)}}bc a†H(P+,0T)a H(P+,0T) {P exp{ig s ∞x−dλn·G(λnµ)}}cd G d,+ν(0,x−,0T)|0>(1)Where Gµ(x)=G aµ(x)λaMann matrices.The subscription T denotes the transpose.G a,µνis the gluonfield strength and a†H(P)is the creation operator for the hadron H.The function D H/Q(z)or D H/G(z) are interpreted as the probablity of a quark Q or a gluon G with momentum k to decay into the hadron H with momentum component P+=zk+,both are gauge invariant from the definitions.The defintions in(1)are the unrenormalized versions,i.e.all quantities are bar quantities(for renormalization see[5]).When one has a parton,i.e.quark or gluon,instead of the hadron in(1),the perturbative expansion in g s,the strong coupling constant,can also be expressed with Feymann diagrams,the Feymann rules can be found in[5,6].The definitions can easily be generalized to hadrons with nonzero spin.From the defintions a direct calculation is possible if one can express the hadron operators with the parton operators.This is possible for a hadron composed of two heavy quarks,where,as mentioned,the nonrelativstic approach works.To see how to express the hadron operator as a parton one,let us consider a spinless hadron to be a bound-state of a heavy quark Q1and an anti-quark¯Q2and to have the quantum number1S0.In its rest frame the state can be expressed as:|1S0>=A0 d3q√√(2π)3f0(|q|)14πχs1s213 color a†s1(p1)b†s2(p2)|0>(4)wherep1=m1m1+m2P−q p(5)q p is related through the Lorenz boost to q in the rest frame.Now it is easy to show that the bound-state satisfies the normalization condition given in[5]as required for the definitions in(1),if one takes the following form for the hadron creation operator: a†H(P)=A0 d3q√√2m1m2P0+|P|(6) Similarly,one can also obtain the operator for the3S1hadronic state:a†H(P,λ)=A0 d3q√√m1m22Mγ5(γ·P−M),for H=1S0stateu(p1,s1)¯v(p2,s2)(ǫi(λ)σiχ)s1s2=−√√Hereǫp(λ)is the4-vector for the polarization of H in the P=0frame.Similar results for the spin sums in Eq.(8)and below can also be found in[7].After a straightforward calculation we obtain for the H=1S0bound-state:D H/Q1(z)=2m32α2sy2z(1−z)281π|R0(0)|2(1−y1z)6·{2−2(1+2y1)z+(15−22y1+16y21)z2+2y1(−5+7y1−6y21)z3+3y31(1−2y1+2y21)z4}D H/Q1(z,λ=±1)=2m32α2sy2z(1−z)224π|R0(0)|2This is also in agreement with that obtained in[2].With our results calculated directly from Eq.(1)one can start with the defintions to calculate the high order corrections.It should be pointed out that the fragmentaion functions calculated here are at the scale µ=M.For the functions at an arbitrary scaleµone needs to solve the correponding renormalization group equations and use the results in Eq.(9,10,11)as initial conditions.With Eq.(9,10,11)we complete the calculations for the fragmentation functions of a S-wave meson.The long-distance effect in these functions are included in the nonrelativstic approach through the radial wave functions at the origin,which can be calculated from potential models or can be directly measured in leptonic decays.For a P-wave meson the calculation is lengthy but still straightforward.Considering a meson to be a J P C=1++ bound state of(Q1¯Q1),the creation operator for this hadron is:a†(P,λ)=A0 8π d3q|q|ǫi2(λ)(σi3χ)s1s2εi1i2i3a†s1(p1)b†s2(p2)(12) and the spin sum used in the calculation:u(p1,s1)¯v(p2,s2)q i1ǫi2(λ)(σi3χ)s1s2εi1i2i3=121108|R′1(0)|2(1−z)(1−z+2z2)}D H/G(z,λ=±1)=α2s4πm51{zof the hadron.The singularity at z=1means that the long-distance effect is present not only in the R′1(0)but also in the remaining parts which we calculated perturbativly and hence it prevents the naive use of perturbation thoery for z near to1.Recent progress[9] on the P-wave hadron decay shows that the long-distance effect can be clearly seperated from the short-distance effect by a new factorization theorem[9]for the decay,where one realizes that any meson is a superpostion of many components:|M>=ΨQ¯Q|Q¯Q>+ΨQ¯QG|Q¯QG>+ (15)and the configuration of|Q¯QG>plays an important roll in the decay.In the hadronic decay of a P-wave meson one should also take account on the|Q¯QG>configuration and the decay width can be written in the new factorization form,where instead of one,two parameters represent the long-distance effect and the remaining parts can be calculated perturbativly without the singularity.To apply this idea in our case,one needs to know the wavefunctionΨQ¯QG in Eq.(15),which can not be obtained through the nonrelativstic approach.A detailed study is needed.Here we recall a phenomenological treatment for the singularity at z=1.Similar treatment of the decay was also used in[8,10].In calculating the contribution from the diagrams to D H/G we integrated the transverse monmentum |p T|,which is carried by the exchanged gluon,from zero to infinity.However,the meson is not a point-like particle and it has a spatial extension.The extension in the transverse direction is of the order R≈1/M.If|p T|is smaller than1/R,one should treat the gluon as a part of the meson.From this point of view,the integral over|p T|should be from a nonzero|p T|min≈1/R to∞.We introduce a parameterβ:|p T|min=βM(16) If the picture given above is correct,βshould be around1.Here we take it as a freeparameter.With Eq.(16)we obtain:D H/G (z,λ=0)=α2s 4πm 51((1−z )2+z 2β2)−3·{z (−2z 7+11z 6−26z 5+35z 4−30z 3+17z 2−6z +1)+3β2z 4(−2z 4+7z 3−9z 2+5z −1)+3β4z 5(−2z 3+4z 2−3z +1)}D H/G (z,λ=±1)=α2s4πm 51((1−z )2+z 2β2)−3·{z (−z 7+6z 6−16z 5+25z 4−25z 3+16z 2−6z +1)+3β2z 3(−z 5+4z 4−7z 3+7z 2−4z +1)}(17)The results in Eq.(17)are finite at z =1and for z →0the expressions approach those given in Eq.(14).In Eq.(17)there are two parameters which need to be determined,the R ′1(0)can be obtained from potential models or measured elsewhere,while βis unknown in principle.However,in the fragmentation functions the dependence on the momentum fraction z is predicted by the perturbative calculations.It should be stressed that it is important to know the fragmentation functions for the P -wave meson or quarkonia.If we take Q 1as a c quark,the quarkonia then corresponds to a χc 1meson and χc 1can substantially decay into J/ψvia radiative decay.Hence,a theoretical prediction of χc 1production via fragmentation is very important for the prediction for the J/ψproduction(for example see [11]and the references cited there).The defintions given in Eq.(1)are for unpolarized partons.One can generalize the definitions to polarized partons and then obtain fragmentation functions for a polarized parton.In this way one can study through heavy meson production the polarization properties of the quarks and gluons produced in high energy collisions,where one expects for large P t processes that the heavy mesons are produced dominantly via fragmentation[2].To summarize:We have shown in this letter that the fragmentation functions for a S -wave meson composed of two heavy quarks can be calculated directly from the definitions given by Collins and Soper in [5]and the results obtained are same as those obtained byother means.A new fragmentation function for a P-wave meson is also obtained,but in contrast to a S-wave meson,there is an extra parameter which needs to be estimated. From the naive picture given above this parameter should be around1.Finally within the defintions one can conveniently study higher order corrections to the fragmentaion functions.Acknowledgement:The author would like to thank Dr.M.Thomson for reading the manuscript carefully.
