The effects of CF content on hardness and tribological properties of the materials were studied. The morphologies of wear surfaces were examined with a Scanning Electron Microscope (SEM). The results show that the hardness and wear resistance ofCF-reinforced UHMWPE composites increased with CF content; the friction coefficients under distilled water lubrication were decreased greatly by the addition of CF; that adherence, plowing, plastic deformation and fatigue wear are dominant for the UHMWPE under dry sliding, and that abrasive wear and drawing out of CF from the wear surface of the composites are dominant for the CF-UHMWPE composites under both dry and distilled water lubrication conditions.

Recently, crosslinking has been introduced in order to reduce the wear of UHMWPE. In this study the wear and wear debris of noncrosslinked and two crosslinked UHMWPE's were compared. In particular this study has focused on the characterisation of nanometre size wear debris.The UHMWPE's were tested in a multidirectional pin on plate wear simulator against smooth and scratched counterfaces. The wear particles were isolated and imaged using a field emission gun scanning electron microscope (FEGSEM) at high resolution. The use of FEGSEM revealed nanometre size particles (less than 0.1 mu m) for the first time. No significant difference was found in the percentage number and percentage volume of the particles in different size ranges from any of the materials against any of the counterfaces. The specific biological activity (biological activity per unit value, SBA) was highest for the highly crosslinked material tested on the smooth counterfaces. The functional biological activity (FBA) which takes into account the wear volume and SBA showed that the highly crosslinked UHMWPE had a lower FBA for debris from both the smooth and scratched counterfaces.

The contact angle and the microhardness of the modified alloys were measured. The friction and wear properties of UHMWPE rubbing against the modified alloys under lubrication of distilled water were investigated using apin-on-disc tribometer. The wettability and the microhardness of the alloy surfaces were found to be increased significantly after ion implantation. The friction coefficient decreased by nearly 5 times and the wear resistance of UHMWPE increased by about 40 times against the ion implanted Ti6Al4V alloy. Many deep furrows were found on the surface of the un-implanted alloy and were absent in the ion implanted surfaces of the alloy. (c) 2006 Elsevier B.V.

These implants incorporate an articulating interface of ultra-high molecular weight polyethylene (UHMWPE) sliding against a polished metallic counterface such as 316L stainless steel. While the design of these joints has been refined over several decades, there are still significant limitations to their pain-free lifetime due to osteolysis induced by UHMWPE particulate. Crosslinking has been used recently to increase the wear resistance of the polymer, but there are significant tradeoffs involving reduced elastic modulus and impact toughness. The authors have proposed using Pt-Zr quasicrystals (QC) as fillers in UHMWPE as a method of increasing the wear resistance of the polymer while avoiding significant losses in mechanical properties. UHMWPE samples that had been irradiation crosslinked, filled with 20 wt.% Pt-Zr quasicrystals, or both, were tested in a dynamic mechanical analyzer to determine their viscoelastic properties. Furthermore, Charpy impact tests were performed on these materials. as well as multi-directional sliding wear tests in the dual axis wear simulator (DAWS), a machine designed to simulate in vivo joint wear conditions. It was found that while crosslinking reduced elastic modulus of UHMWPE over 30%, the use of QC fillers led to a slight increase. Additionally, the reduction inimpact toughness when using QC fillers was not as great as with crosslinking. Finally, it was found that both QC fillers and crosslinking provided the same significant reduction in wear amounts over untreated UHMWPE. The reduction in wear is explained in terms of the wear mechanisms. This involves inhibition of polymer chain orientation in the case of crosslinking, and shear load shielding effects of quasicrystals in the case of QC-filled polymer. These results suggest that Pt-Zr quasicrystal filler may be a desirable alternative to crosslinking when attempting to increase the wear resistance of UHMWPE for biomedical applications.

The PE blend with desirable fluidity was obtained by melt mixing UHMWPE and low molecular weight polyethylene (LMWPE), and then was processed by a modified injection molding technology-oscillatory shear injection molding (OSIM). Morphological observation of the OSIM PE blend showed LMWPE contained well-defined interlocking shish-kebab self-reinforced superstructure. Addition of a small amount of long chain polyethylene (2 wt %) to LMWPE greatly induced formation of rich shish-kebabs. The ultimate tensile strength considerably increased from 27.6 MPa for conventional compression molded UHMWPE up to 78.4 MPa for OSIM PE blend along the flow direction and up to 33.5 MPa in its transverse direction. The impact strength of OSIM PE blend was increased by 46% and 7% for OSIM PE blend in the direction parallel and vertical to the shear flow, respectively. Wear and fatigue resistance were comparable to conventional compression molded UHMWPE. The superb performance of the OSIM PE blend was originated from formation of rich interlocking shish-kebab superstructure while maintaining unique properties of UHMWPE. The present results suggested the OSIM PE blend has high potential for artificial joint application.4.4Ei Compendex (Ei)4.4.1题名：Comparison of wear debris generated from ultra high molecular weight polyethylene in vivo and in artificial joint simulator作者：Hongtao, Liu1; Shirong, Ge2; Shoufan, Cao1; Shibo, Wang2出处：Wear，2011,卷：271，期：5-6，页：647-652，摘要：The artificial joint simulator is designed to simulate the complicated movement and environment of the artificial joint in vivo. Although the wear loss of materials evaluated on the artificial joint simulator under ISO standard is found to conform to that in vivo, there is a significant difference in the morphology of the wear debris obtained from the tester and human body. It is well known that the wear debris plays an important role in aseptic loosening of the artificial joint, and its morphology indicates the working conditions of the artificial joint. Therefore, it is necessary to distinguish the two kinds of wear debris. In this paper, the comparative study of ultra high molecular weight polyethylene (UHMWPE) wear debris from the implanted artificial joint and hip joint tester was performed on their size distribution,shape, 3-D feature, and thickness. Results show that the wear debris from joint simulator have different sizes and shapes such as strip, block, plate, and spherical etc., their average diameter is 7.54 μm, and its medium diameter is 6.89 μm. The most wear debris from artificial joint have the spherical or subsphaeroidal shapes, and a small amount of the debris have the unbroken plate structure, the average diameter is 1.33 μm, is about 18% of the wear debris' from joint simulator, and the medium diameter of 2.95 μm, is about 43% of the wear debris' from joint simulator. The results are expected to provide both experimental and theoretical foundationfor improving the artificial joint simulator and optimizing the evaluation standards of the artificial joint materials. © 2011 Elsevier B.V.4.4.2题名：Biotribological properties of UHMWPE grafted with AA under lubrication as artificial joint作者：Deng, Yaling1; Xiong, Dangsheng1; Wang, Kun1出处：Journal of Materials Science: Materials in Medicine，2013，卷：24，期：9，页：2085-2091摘要：Osteolysis caused by wear particles from polyethylene in the artificial hip joints is a serious issue. In order to endow the low friction and wear of the bearing surface of ultra-high molecular weight polyethylene (UHMWPE) artificial joint for a longer term, hydrophilic acrylic acid (AA) was grafted on UHMWPE powders with the method of ultraviolet irradiation and then the modified powders were hot pressed. The tribological properties of modified UHMWPE sliding against CoCrMo metallic plate on reciprocating tribometer under calf serum, saline and distilled water lubrication during a long-term friction were investigated. The measurement of Fourier-transform infrared spectroscopy indicates that AA is successfully grafted on the surface of UHMWPE powders by photo-induced graft polymerization. Contact angles of UHMWPE are decreased from 83 to 35 by grafting and the surface wettability is effectively improved. The tensile strength of modified sample decreases. The friction coefficient and wear rate of UHMWPE-g-PAA under calf serum, saline and distilled water lubrication are lower than that of untreated UHMWPE. With the increase of grafting ratio, the wear rate of UHMWPE-g-PAA decreases firstly and then increases. The modified UHMWPE with grafting ratio of 3.5 % has the lowest wear rate, which is just quarter of the untreated UHMWPE. The hydrated PAA polymer brushes enclosed in the UHMWPE bulk material provide continuous lubrication during long term sliding. © 2013 Springer Science+Business Media New York.4.4.3题名：An activated energy approach for accelerated testing of the deformation of UHMWPE in artificial joints作者：Galetz, Mathias Christian1; Glatzel, Uwe1出处：Journal of the Mechanical Behavior of Biomedical Materials，2010，卷：3，期：4，页：331-338摘要：The deformation behavior of ultrahigh molecular polyethylene (UHMWPE) is studied in the temperature range of 23-80 °C. Samples are examined in quasi-static compression, tensile and creep tests to determine the accelerated deformation of UHMWPE at elevated temperatures. The deformation mechanisms under compression load can be described by one strain rate and temperature dependent Eyring process. The activation energy and volume of that process do not change between 23 °C and 50 °C. This suggests that the deformation mechanism under compression remains stable within this temperature range. Tribological tests are conducted to transfer this activated energy approach to the deformation behavior under loading typical for artificial knee joints. While this approach does not cover the wear mechanisms close to the surface, testing at higher temperatures is shown to have a significant potential to reduce the testing time for lifetime predictions in terms of the macroscopic creep and deformation behavior of artificial joints. ©2010.4.4.4题名：Elementary study of modifying UHMWPE with schiff base copper complex for the use as an artificial hip joint material作者：Gao, Xinlei1; Hua, Meng2; Li, Jian3; Gao, Wanzhen3出处：Journal of Dispersion Science and Technology，2009，卷：30，期：7，页：1059-1066摘要：Elementary micro-tribological test for UHMWPE modified with 15 wt% of Schiff base copper complex (Cu(II) chelate of bissalicylaldehyde-ethylenediamine rubbed by titanium alloy showed that a reduction of 20% friction coefficient when compared with the pure UHMWPE/titanium alloy pair under the condition of dry friction. Under a simulating loading level of an artificial hip joint, the highest frication coefficient of the modified UHMWPE pairing with steel was 15% lower than its pure UHMWPE/steel pairing counterpart. Furthermore, wear of the modified UHMWPE was very mild almost without any sign of worn debris even being run for a sufficiently long period, while the pure UHMWPE could run only for a very short period. Test results confirmed that the Cu(II) chelate ofbissalicylaldehyde-ethylenediamine modifying UHMWPE was able to reduce friction, wear and debris during application. Besides excellent tribological characteristics, good biocompatibility of the modified UHMWPE was also demonstrated by a cell toxicity test in vitro. T Consequently, attempts to develop this modified UHMWPE for artificial joint is obviously beneficial. © Taylor & Francis Group, LLC.4.4.5题名：Molecular deformation mechanisms in UHMWPE during tribological Loading in Artificial Joints作者：Galetz, Mathias Christian1; Glatzel, Uwe1出处：Tribology Letters，2010，卷：38，期：1，页：1-13摘要：No clear picture of the deformation and wear mechanisms of Ultra High Molecular Weight Polyethylene (UHMWPE) in artificial knee joints exists up to today. Tri-bological tests were conducted under relevant loads and the worn samples were extensively studied by XRD, DSC, Raman, and SEM. It was shown that stresses close to the surface in areas where high relative velocity in combination with high normal loads are applied are most effective in changing the microstructure and therefore most detrimental to produce wear particles, while in the depth the same deformed structure as under unidirectional cyclic loading is found. A model was proposed which reflects the deformation at different zones in the depth of a tribologically loaded UHMWPE sample. This model shows amazing analogy to the orientation of collagen fibrils in natural cartilage. © Springer Science+Business Media, LLC 2010. 4.5国家知识产权局专利数据库4.5.1发明名称：一种人工关节用可熔体加工的超高分子量聚乙烯复合材料公开（公告）号：CN103751849A申请（专利权）人：四川大学发明人：李忠明;黄妍斐;雷军;钟淦基;徐家壮;徐玲摘要：本发明涉及一种人工关节用可熔体加工的超高分子量聚乙烯复合材料。

SUSIRI基因的过表达未出现使稻穗性状明显改良的株系,而RNA干扰会导致水稻的结实能力严重降低.（4）玉晓红，晁丽等. 利用RNA干涉研究水稻锌指蛋白基因OsZRL的功能. 中国水稻科学 ISSN：1001-7216（5）马廷臣，陈荣军. 渗透胁迫下水稻根系核仁小分子RNA转录本变化的全基因组表达分析. 中国水稻科学 ISSN：1001-7216CNKI：检出文献篇数634篇，经筛选列出如下5篇相关文献（1）毕延震. 天然反义RNA(NATs):基因表达的重要调控分子.中国生物化学与分子生物学报.（2）宋莉芸. 一个水稻DEAD盒RNA解旋酶基因OsBIRH1的克隆鉴定及其蛋白纯化. 浙江农业学报(3)刘红美.用RNA干涉对几个水稻WD结构域基因的功能研究. 华南农业大学学报.(4)王海燕.磷脂酶Ds在植物干旱胁迫反应中的功能与作用机理.中国农业科学院.(5)许凤莲.一个具有S位点的水稻类受体激酶OsSRL参与干旱胁迫反应.植物学报.Sciencedirect：检出文献篇数679篇，经筛选列出如下5篇相关文献（1）Marco Magistri, Mohammad Ali Faghihi等Regulation of chromatin structure by long noncoding RNAs: focus on natural antisense transcripts（2）Yu Wang, Wei-Jun Pang等，Identification, stability and expression of Sirt1 antisense long non-coding RNA，(3)Claes Wahlestedt，Natural antisense and noncoding RNA transcripts as potential drug targets(4) Jin-hua He, Yu-guang Li，Characteristics of Antisense Non-coding RNA in the INK4 Locus and Its Roles in Disease(6)Kinji Kurihara, Nobuo Nakanishi，Expression of Na+/K+-ATPase α subunitisoforms in rat salivary glands: Occurrence of sense and antisense RNAs of the α3isoform in the sublingual glandweb of science：检出文献篇数571篇，经筛选列出如下5篇相关文献（1）Wang, Yu; Pang, Wei-Jun; Wei, Ning; 等，Identification, stability and expression of Sirt1 antisense long non-coding RNA.（2）Saldana-Meyer, Ricardo等，CTCF regulates the human p53 gene through direct interaction with its natural antisense transcript, Wrap53.（3）Wang, Huan; Chung, Pil Joong; Liu, Jun; 等，Genome-wide identification of long noncoding natural antisense transcripts and their responses to light in Arabidopsis.（4）Isobe, Hiroyuki; Fujino, Tomoko，Triazole-Linked Analogues of DNA and RNA ((TL)DNA and (TL)RNA): Synthesis and Functions（5）Watanabe, Takeshi; Asakawa, Susumu; Nakamura, Asumi; 等，DGGE method for analyzing 16S rDNA of methanogenic archaeal community in paddy field soil.万方学位论文数据库：检出文献篇数309篇，经筛选列出如下5篇相关文献（1）谢兆辉.天然反义转录物及其调控基因的表达机制.遗传HEREDITAS(BEIJING)（2）Morris, R.

计算机信息检索实验报告(6个)

实验一网上中文搜索引擎及其使用一、实验心得在电脑已经成为生活必备品的现在，日常搜索是一件很平常的事情。

俗话说，天天百度知识丰富。

当然，我国国内主要的搜索引擎除了百度，还有谷歌、雅虎、搜狗、网易、新浪。

一般来说，百度和谷歌是最多人用的。

不同的搜索引擎，不同的搜索方法，得到搜索结果的速度和准确度也不一样。

所以我觉得学习计算机信息检索的主要目的就是更好地提高自己搜索的速度和准确度。

在这次实验当中，我们主要学习和掌握以下搜索技巧的运用。

「“”」的基本用法、「+」或「空格」的基本用法、「+」的基本用法、「-」的基本用法、「OR」的基本用法、「site」的基本用法、「inurl」的基本用法、「intitle」的基本用法、「filetype」的基本用法。

比起以前直接把整个问题打上去然后从网页中寻找满意的答案，灵活使用这些搜索技巧可以更快地找到准确率高的答案。

这些技巧在现实生活中具有高度的可操作性和便捷性。

二、实验结果（一）请使用Google或百度搜索引擎完成以下知识测验：（请将检索结果复制到题干之后，并把所有有关的网页都下载到你的作业文件夹中，以作为本作业评分的依据。
