《钢铸件浇冒口方案》中包括的指导方针以铸造实验以及计算机模拟为基础。
该指导手册为钢铁铸造行业带来了福音。
遵循指导手册开展铸造作业获得的铸造件通常都是无疵铸件。
但是,在过去二十五年中出现的情况表明,《钢铸件浇冒口方案》中规定的冒口补缩距离规则在某些情况下显得太过保守,当利用规定的冒口补缩距离规则推断结果时,情况就更是如此。
因为补缩距离规则相对保守,导致出现铸造件冒口浪费情形,而这种情形进而降低了铸件产量。
为制订一套新的浇冒口指导原则[2、3],从二十世纪九十年代中期开始,开展了大量研究工作。
研究工作以一组广泛的低合金钢板铸造实验为基础,实验在北美洲的多家铸造厂进行。
在实验中使用了多种钢板尺度,生产出了各种规格的铸造件,从影像学角度来讲的无疵铸件以及ASTM收缩X射线5级(ASTM shrinkage x-ray level 5)铸件均在其列。
各铸造厂分别记录了每个钢板铸件的铸造条件(合金成分、模具材料、过热、浇注时间等),后来借助现代铸造模拟软件,利用这些信息对各钢板的铸造进行了数值模拟。
《鼻》提到禅智内供的鼻子,在池尾是没有人不知道的。
他的鼻子长达5、6寸,从上嘴唇开始一直垂到下颚。
形状是鼻尖和根部一样的大。
酷似香肠一样的东西,遥遥晃晃的从脸的正中间垂下来。
现在已超过50岁的内供,从小沙弥开始做起,直到升到现在内道场供奉的职位,内心始终因为这个鼻子的问题而感到苦恼。
当然表面上还是装作一副不以为然的样子。
这并不是单单觉得作为一个潜心祈求来世净土的和尚,过分担心自己的鼻子是不对的。
他更讨厌别人知道自己很介意自己的鼻子。
内供在日常的谈话中,最害怕提到鼻子这一词语。
内供对鼻子感到难以应付的原因有两个。
一个是现实的原因,因为鼻子太长而带来的不便。
第一,没办法独自一个人吃饭。
如果自己一个人吃饭的话,鼻尖就会先碰到碗里的饭。
内供就吩咐一个徒弟坐在对面,吃饭的时候,让他用一寸宽两尺长的木条替自己挑着鼻子。
可是像这么吃法,不论是掀鼻子的徒弟,还是被掀的内供,都颇不容易。
一回,有个中童子来替换这位徒弟,中童子打了个喷嚏,手一颤,那鼻子就扎到粥里去了。
这件事当时连京都都传遍了。
然而这决不是内供为鼻子而苦闷的主要原因。
说实在的,内供是由于鼻子使他伤害了自尊心才苦恼的。
池尾町的人们都为长着这样一个怪鼻子的禅智内供着想,说幸好他没有还俗。
因为有着那样的鼻子的话,娶到妻子的希望是渺茫的。
其中甚至有人评论道,内供是不是正是因为长着那种鼻子才出家的。
不过内供倒不觉得当了和尚后鼻子带来的烦恼就有所减少。
他所苦恼的,是不会被娶妻这种实质性的事实所左右的,说到底还是那牵扯到自己极易受伤的自尊心的内在问题。
于是,内供开始尝试用积极的和消极的方法来恢复自己那已被损伤的自尊心。
内供最先想到的就是让长鼻子看起来比实际要短一些的方法。
这个做法就是在没有人的时候,自己走到镜子前,从各个角度照自己的脸,热切地寻找着能使鼻子看上去短点的姿势。
有时,仅仅转换一下脸的位置,则不能使内供感到满意,有时候托腮,有时候用手指紧贴着下颚,有时候也会很有耐心地尝试从镜子里窥视自己。
外文文献翻译译稿1卡尔曼滤波的一个典型实例是从一组有限的,包含噪声的,通过对物体位置的观察序列(可能有偏差)预测出物体的位置的坐标及速度。
在很多工程应用(如雷达、计算机视觉)中都可以找到它的身影。
同时,卡尔曼滤波也是控制理论以及控制系统工程中的一个重要课题。
例如,对于雷达来说,人们感兴趣的是其能够跟踪目标。
但目标的位置、速度、加速度的测量值往往在任何时候都有噪声。
卡尔曼滤波利用目标的动态信息,设法去掉噪声的影响,得到一个关于目标位置的好的估计。
这个估计可以是对当前目标位置的估计(滤波),也可以是对于将来位置的估计(预测),也可以是对过去位置的估计(插值或平滑)。
命名[编辑]这种滤波方法以它的发明者鲁道夫.E.卡尔曼(Rudolph E. Kalman)命名,但是根据文献可知实际上Peter Swerling在更早之前就提出了一种类似的算法。
斯坦利。
施密特(Stanley Schmidt)首次实现了卡尔曼滤波器。
卡尔曼在NASA埃姆斯研究中心访问时,发现他的方法对于解决阿波罗计划的轨道预测很有用,后来阿波罗飞船的导航电脑便使用了这种滤波器。
关于这种滤波器的论文由Swerling(1958)、Kalman (1960)与Kalman and Bucy(1961)发表。
目前,卡尔曼滤波已经有很多不同的实现。
卡尔曼最初提出的形式现在一般称为简单卡尔曼滤波器。
除此以外,还有施密特扩展滤波器、信息滤波器以及很多Bierman, Thornton开发的平方根滤波器的变种。
也许最常见的卡尔曼滤波器是锁相环,它在收音机、计算机和几乎任何视频或通讯设备中广泛存在。
以下的讨论需要线性代数以及概率论的一般知识。
卡尔曼滤波建立在线性代数和隐马尔可夫模型(hidden Markov model)上。
其基本动态系统可以用一个马尔可夫链表示,该马尔可夫链建立在一个被高斯噪声(即正态分布的噪声)干扰的线性算子上的。
系统的状态可以用一个元素为实数的向量表示。
外文文献翻译译稿1可用性和期望值来自Willliam S.Green, Patrick W.Jordan.产品的愉悦:超越可用性根据人机工程学会(HFES)的观点,人机工程学着眼于“发现和共享可用于各种系统和设备设计的、关于人的特点的知识”。
人们通常只是把它作为生物力学和人体测量所关注的内容,实际上它是从更广泛的意义上的一种对人(产品用户)的全面和综合的理解。
HFES从二战中有军方从事的系统分析中发展而来。
其中的三种主要研究的是人体测量、复杂信息的解释和管理,以及在部队和装备调配中应用的系统分析。
系统分析在尺度和复杂性方面跨度很大,大的系统分析有类似于诺曼底登陆准备的大型系统规划,小到去理解如何从合理性和规模的角度才最佳的布置和装备人员。
诺曼底登陆是20世纪最复杂的事件之一。
他要求建立一个在战斗开始之前还不确定的庞大的人员和物资的合理分配系统。
在更小的规模上,装备和军事人物的布置意味着如何去组织、训练和安排战士,最大限度的发挥他们的长处。
士兵必须迅速地接受训练,并且能够有效地使用和维护在二战中发展起来的一系列技术装备。
其中,对于飞行员、潜艇人员和坦克驾驶员有神采的限制。
复杂的新装备的开发要求找到最好的税收、密码便医院、破译人员、雷达和声纳操作员、轰炸机驾驶员和机组人员。
在战后,随着公司及其产品在尺度、领域和复杂性方面的增长,很多系统分析人员在商用领域找到了发展机会。
尽管是战后的发展才导致了1957年人机工程协会(HFES)的建立,但人机研究的起源可以追溯到大批量生产方式的成型阶段,是当时提高生产效率的要求。
随着工作方式从手工生产和农业生产中的转移,新的工厂工作的概念逐步发展起来。
福特的流水生产线和泰勒的效率理论开始对生产的规划和教育产生影响。
即使在家庭生活中,妇女们也开始接受了现代家庭管理理论,并运用这些理论来组织和规划家庭。
在20世纪末,一种涵盖面更广的人机工程正在发展之中。
新的人机工程学是为了适应已经被广泛意识到的对用户行为模式更深入的需求而诞生的,它开始应用定型研究方法,并探索人的情感和认知因素。

Role setAny individual in any situation occupies a role in relation to other people. The particular individual with whom one is concerned in the analysis of any situation is usually given the name of focal person. He has the focal role and can be regarded as sitting in the middle of a group of people, with whom he interacts in some way in that situation. This group of people is called his role set. For instance, in the family situation, an individual’s role set might be shown as his wife, Children’s school, Joint friends, neighbours and so on.Role definitionThe definition of any individual’s role in any situation will be a combination of the role expectations that the members of the role set have a focal role. These expectations are often occupationally defined, sometimes even legally go. The role expectations of the lawyers and doctors are fairly clearly defined both in legal and in cultural terms. The role definition of, say, a film star or bank manager, are also fairly clearly defined in cultural terms, too clearly perhaps.Individuals often find it hard to escape from the role that cultural traditions have defined for them. Not only with doctors or lawyers is the required role behaviour so constrained that if you are in the role for long it eventually becomes part of you, part of your personality, Hence, there is some likelihood that all accountants will be alike or that all blondes aresimilar--- they are forced that way by the expectations of their role.It is important that you make it clear what your particular role is at a given time. The means of doing this are called, rather obviously, role signs, The simplest of role signs is a uniform. The number of stripes in your arm or pips on your shoulder is a very precise role definition which allows you to do certain very prescribed things in certain situations. Image yourself questioning a stranger on a dark street at midnight without wearing the role signs of a policeman.!In social circumstances, dress has often been used as a role sign to indicate the nature and degree of formality of any gathering and occasionally the social statue of people present. The current trend of towards blurring these role signs in dress is probably democratic, but it also makes some people very insecure. Without role signs, who is to know who has what roles?Place is another role sign. Managers often behave very differently outside the office and in it, even to the same person. They use the change of location to indicate a change in role room, say boss to friend. Indeed, if you wish to change your role, you must find some outward sign that you are doing so or you won’t be permitted to change--- the subordinate will continue to hear you as his boss no matter how hard you try to be his friend. In very significant cases of role change, e.g, from a solider in the ranks to officers, from bachelor to married man, the change of role has tohave a very obvious sign, hence rituals. It is interesting to observe, for instance, some decline in the emphasis given to marriage person, and therefore no need for a public change in sign.In organizations, office signs and furniture are used as role signs. These and other perquisites of status are often frowned upon, but they may serve a purpose as a kind of differing in a democratic society; roles without signs often lead to confused or differing expectations if the role of the focal person.Role ambiguityRole ambiguity results when there is some uncertainty in the minds, either of the focal person or of the members of his role set, as to precisely what his role is at any given time. One of the crucial expectations that shape the role definition is that of the individual, the focal person himself. If his occupation of the role is unclear, or if it differs from that of the others in the role set, there will be a degree or role ambiguity. Is this bad? Not necessarily, for the ability to shape one’s own role is one of the freedoms that many people desire, but the ambiguity may lead to role stress which will be discussed later on. The virtue of job descriptions is that they lessen this role ambiguity. Unfortunately, job descriptions are seldom complete role definitions, except at the lower end of the scale. At middle and higher management levels, they are often o list of formal jobs and duties that say little therefore to give the individual an uncomfortablefeeling that there are things left unsaid, i,e. to heighten the sense of role ambiguity.Looking at the ambiguity from the other side, from the point of view of the members of the role set, lack of clarify in the role of the focal person can cause insecurity, lack of confidence, irritation and even anger among members of his role set. One list of the roles of a manager identified the following: executive, counselor, friend, teacher. If it is not clear, through role signs of one sort or another, which role is currently the operational one, the other party may not react in the appropriate way—we may, in fact, hear quite another message if the focal person speaks to us, for example, as a teacher and we hear her as an executive.角色集每个个体在各种情形下都会拥有一个与他人相联系的角色。
五魁将女人背到了很深很深的山林。
Wukui(a man’s name)carried the woman on his back into the vastly deep mountain forest.山高月小,他拐进一条沟荒不择路,直走到了两边的山梁越来越低,越来越窄,最后几乎合二为一在一座横亘的大岭峰下,已是第二日的中午了。
感觉到鸟飞天外,鱼游海底,柳家是不会寻得着了,坐下来歇息,啃了块从家里出走时揣在怀里的玉米面饼子,两人皆觉得没有一丝力气可以再迈动一步了。
这是什么地方?翻过这黑黝黝的岭峰之后那边又将是什么地方?女人询问着五魁,五魁也茫然无答。
走到哪儿算哪儿,哪儿的黄土不养人呢?五魁放下了女人,要到看不见也闻不着的地方去解手,大出意外地发现了一座坍得几乎只有四堵墙的山神庙,墙头一株朽了半部靠一溜树皮还活着的老柏,庙后的涧上桥已断去,残留了涧沿一根腐木,卧一秃鹰呆如石头,偏很响地拉下了一股白色的稀粪。
五魁一时四肢生力,跳蹦着过来如孩子:With the high mountain and the distant moon, he turned into a ravine and was too panic to choose a right way to go. He did not stop until the ridges on his both sides were getting lower and narrower,eventually, nearly combining into one at the foot of another large ridge, which was sitting horizontally before them. It was already at noon of the second day that a feeling of birds flying up in the sky and fish swimming down in the sea grasped them. Thinking it was impossible for the Lius to find them, thus they sat down to take a breath. Both of them were too tired to move even a small step, then beginning to nibble at the cornbread which Wukui hid in his shirt when he fled home. The woman asked Wukui about the name of this place and the one over the dark, large ridge, while he said nothing but being at a loss. In a minute he said that they went wherever the way would take them, for the yellow soil could nurture them wherever they were. Wukui set the woman down and wanted to find a hidden place, where could not be seen or smelt, to relieve himself, but unexpectedly to find a collapsed mountain temple with only walls, over which was anold cypress, which was half decayed and sustained only by bark. Behind the temple, there was a valley stream where a broken bridge leaving a rotten wood, upon which standing a still,stone-like vulture, which just gave out a flow of white shit loudly. Right at that moment, feeling strong in his limbs, Wukui bounced and rushed towards the woman like a child and exclaimed:“咱有住的了!”“We have a place to live!”女人眼睛也亮起来:“在哪儿?”The woman’s eyes lit up. “Where is the place?”, she asked?五魁说:“那边有个山神庙!既然有庙,必定先前住过了人,住过人就有活人处,咱们住在这儿不会死了!”Wukui said,”There is a mountain temple over there! Someone must have been living here! And I’m sure we will not die here!”把女人背过来,钻过梢林和荒草,女人的身上、被子上,头发上沾满了一种小小的带刺的草果。

首先,我认为传统家庭有利于孩子的成长。
众所周知,每个孩子在成长过程中需要母爱以及父爱,缺一不可。
通常而言,单亲家庭的孩子相对传统家庭的孩子不够健全。
我认为是缺少父爱或母爱而引起的。
这些孩子在平时生活中也缺少安全感、不够自信。
其次,我认为对孩子也不够公平。
众所周知,虽然同性恋逐渐被社会所认可,但是还没有成为主流文化。
在孩子成长过程中,难免会被传统家庭中的孩子嘲笑。
这对一个世界观还未成熟的孩子来说是不公平的。
最后,我们应该想办法,尽我们最大的努力让一个孩子可以在同性恋家庭中健康、快乐的成长。
可以享受到完整的爱,可以接受正确的价值观。
因为已经有孩子正成长在同性恋家庭中。
我们应该引导社会不去歧视这些孩子。
原稿Apple had a trick up its sleeve during Monday’s special event. And no, it wasn’t the Apple Watch.苹果全新Mac笔记本试用总结The company announced a new laptop, which it calls simply Mac Book, that looks more like a Mac Book Air that went on a diet. How slim, you ask? It measures just 13.1 millimeters at its thickest point, and weighs in at a mere 2.03 pounds. And then you put your hands on it and realize. Gosh, it’s small. Incredibly small. Unbelievably small.I repeated a similar phrase during the keynote that introduced it, which I live-blogged for this very publication. It’s easy to think dwell on size when the device is the sole item on a sweeping black stage. It’s another thing to walk into App le’s demo area, lay your eyes on the gold, silver, and grey varieties, and think the same thing all over again. Apple’s new Mac Book is indeed all-new, and it’s a complete overhaul of the device, from components on out. It lacks fans of any sort and relies on an energy-efficient Intel Core M processor to keep it cool and prolong battery life, which Apple claims lasts an entire day. Its screen, the so-called high-resolution Retina display, measures 12 inches on the diagonal, situating the new laptop in betwe en Apple’s two models of Mac Book Air, at 11 inches and 13 inches. The difference: That Retina display packs 2304 pixels across by 1440 pixels down into that diminutive picture.Each key features a new “butterfly mechanism” that provides for a unique typin g experience. It’s one that I struggled with during my hands-on time with the new Mac Book. It’s not that the keys are hard to press, or even awkwardly placed. If anything, the keys are almost too easy to press. A touch-typist will fall in love with it after just a few minutes of tapping away. Others will take long to adjust to a keyboard that stretches to the very edges of the Mac Book’s housing. I’m in the latter camp.A new track pad offers the same “Force Touch” technology found in the Apple Watch. Push past the marketing and you’ll find a track pad that doesn’t move when pressed, no matter how hard you do so. (Well, within reason—don’t shove the thing off a table.) Its immobility allows it to differentiate between amounts of pressure, and by extension, intent to accomplish different tasks.For example, moving the mouse pointer over a file icon and Force Touching on the track pad prompts Quick Preview to open. See an address in an e-mail? Force Touch on it and a dialogue box with Apple Maps appears to reveal its exact location.Similar shortcuts are present throughout the updated Mac OS X operating system. You can adjust the degree of pressure in the System Preferences area. And try as I might on the floor of the Yerba Buena Center in San Francisco, I still couldn’t believe that the new Mac Book’s track pad wasn’t actually moving. Apple assured me it’s not. The “Tactic Engine” underneath the aluminum pad leaves the user with the impression that it’s traveling in space. Color me impressed—or confused.There is a notable lack of ports on the new Mac Book. In fact, there’s only one. (Well, two if you want to make the argument a headphone-jack is a port.) On its left flank is a USB Type-C port. Think of it as the more capable, younger sibling of the Lightning adapter on your IOS device. Through this single port you can charge the Mac Book, transfer content, and connect it to an external monitor. It’s the Swiss Army Knife of connectors, though for now at least, external monitor functionality will require a series of adapters. Why? USB Type-C is a new standard—one that most accessory manufacturers have yet to fully commit to, let alone release products with it incorporated. So for now, adapters will be a necessity for Mac Book owners.As someone who works primarily from an IPAD, I can’t complain about the lack of ports. For me, adapters are a way of life and something I’ve come to accept. But that’s not for everyone, and Apple’s minimalism will be a break in how we’ve come to think about the desktop/laptop computer. I asked several attendees at the Apple event what they thought about this issue; reactions ranged from excited to discourage. (The concerns of the latter group: what’s the point of ultra portability if I need to carry around a bunch of adapters? Fair point.) That Apple’s adapters are priced as high as $79 won’t help.But back to the new Mac Book. Its Intel M Core processors clock in at a lowly 1.1GHz and 1.2GHz respectively, which is cause for concern. I wasn’t able to fully test either version outside of A pple’s demo area, unfortunately, so I can’t comment on their overall performance. I can say that during the limited time I used the new Mac Book—to watch videos, browse through a Photos library, and accomplish other miscellaneous tasks—I was left with the impression that comparatively slow processors wouldn’t adversely impact performance too much.But that’s not the real point. Apple’s new Mac Book is transformative based on its size alone. To put it into perspective, the new Mac Book is only slightly heavier (and far thinner) than my IPAD-plus-keyboard setup, but it’s a full-fledged content creation device.Which has me, and I suspect many other people, wondering: Laptop. Tablet. Now what?。
