Based on the example of turbine reverse engineering , the general procedure that can be used to translate the physical object into CAD datum by Surfacer software is determined in this paper1 By going deep into the vector of point-cloud , it's parametrization can be gained by adopting the precept of accumulating chordal parametrization1 According to the principle of const ructing curve using the least square method , the high quality-curve can be gained by modifying curve's parameter1 This paper also empha2sizes on some methods about processing point-cloud , const ructing curve and const ructing surface1 And it can provide several methods to const ruct high quality2CAD model for mould machining1

The market was abounded, goods goes as climate and other natural phenomena of a season no longer, we are OK the third nine-day period after the winter solstice-coldest days of winter eats on cooling watermelon, dog days eats on tastily aspic pear, we have austral coconut tree on the brightest, african mango wants to eat you to be able to be bought at any time...

市场丰富了，商品不再随着节令走，我们可以三九天吃上清冽的西瓜，三伏天吃上爽口的冻梨，南国的椰子我们吃上最鲜的，非洲的芒果想吃你随时可以买到……当我们由衷地赞美改革开放的盛果时，却可曾想到，是谁把我们过去连想都不敢想的事变成了现实。

Bond strength may be an easy way to test: If the cover page with a coating material or fabric, and so on and Board bond, of post-drying in bond over time, will cover material on jeyang to pull apart, should be able to bring push-out of cardboard surface tear tape, books and cover bond tore post-drying reached does not open or a leaf out of another layer of still being bonded on it, you can achieve the requirements.

黏结强度可用下述简单方法测试：如封面用涂布类材料或织品等与纸板黏结，在黏结干燥后的一定时间，将封面料揭撕开时，应能把被黏结的纸板表面也撕带下一层，书册与封面黏结干燥后达到撕不开或撕下一层，而另一层仍被黏结在上面，即可达到要求。

According this, the thesis broadens the content of the Union of Nature and Man, and pointed that it should be built on full understand on nature and man, acknowledge nature"s inherent value, definite man"s responsibility to nature, then stress difference in unit and unit in difference. On the basis of it, the Union of Nature and Man world outlook is set up, which may be useful to transform Mans concept of environment and morality, and to promote perfect rules and international collaboration, and to set up right development view, and finally realize the harmony between nature and man.

据此，本文拓展了"天人合一"的内涵，明确指出"天人合一"思想应当建立在对自然界和人类自身的充分认识之上，承认自然的内在价值，肯定人对自然负有责任，在差别中强调合一，在合一中强调差别，并在此基础上，树立天人合一自然观，以从根本上改造人们的环境意识和道德观念，促进制度完善和国际协作，建立正确的发展观，最终实现人与自然的和谐共生。

But the countries have different opinions on economic、soc ial and cultural rights,which are important to the minority.After comparing and analyzing the cultural tradition of some countries on right issues and the varia nt theories of equality,the article points out that on such issues as the econom ic social and cultural rights,positive actions should be taken and diverse discr imination should be avoided to give the minorities more opportunities to partici pate in social competition and realize complete equality in the whole society an d more equality with more justice.

然而，在对少数人具有重要意义的经济、社会、文化权利上，各国却有不同的看法，本文在比较了各国在权利问题上的文化传统和近现代的各种平等理论之后，分析指出在以经济、社会、文化权利为核心的相当一部份权利上，各国政府应当在避免形成"反向歧视"的前提下，采取积极措施，让少数人有更多机会参与社会竞争，实现社会整体的平等和更公正意义上的平等。

This study considered that Liberty Times indeed improved the retail rate on weekend market after the release of Weekender, which contributed to the survival of newspaper office. But it might be insufficient to win from the battle lines on news marker if only to reform specific layouts on specific dates, it would be a lasting good order to have comprehensive review and innovation.

本研究认为《自由时报》推出周末生活版之后，确实改善该报在假日零售市场的销售率，对於报社的持续生存颇具贡献，但是光在特定日期或特定版面才推出改良商品，可能不足以从新闻市场的战线中胜出，下定决心推动通盘的检讨与改革，才是长久之计。

Often you see men working at office desks without their suit coats and ties,they may lean far back in their chairs and even put their feet up on the desk while they talk on the phone,but this is not meant to be rude,they are informal,most likely because they are always in a great hurry:city people always appear to be hurrying to get whee they are going and would be very impatient ifthey are delayed even for a brief moment.

我们经常可以看见有人在办公室里没有穿他们的西装打领带，他们靠在椅子上甚至将自己的脚放在桌子上打电话，但是，这不代表不礼貌，他们随意，几乎可能会匆忙的打招呼，城市里人总是会表现的很匆忙，当他们肯能回非常没有耐心当他们因为短时间的耽搁。

Because,this is, on one hand, china is in " into the world " when about opening the market, commerce liberalizes and the acceptance such as blame discrimination pay needs to lean greatly " antitrust law " make and carry out be able to come true; On the other hand, make and carry out " antitrust law " be helpful for ruling by law acceptedly with each country enterprise of method standard foreign country (especially transnational corporation) the competitive behavior on Chinese market, rise to defend the action of national economy safety.

这是因为，一方面，中国在&入世&时关于开放市场、贸易自由化和非歧视待遇等承诺在很大程度上需要靠《反垄断法》的制定和执行得以实现；另一方面，制定和实施《反垄断法》有利于以各国公认的法治手段规范外国企业在中国市场上的竞争行为，起到维护国家经济安全的作用。

Rather than dealing with the deficits, Bush touts his policy of "free prescription drugs" for the elderly —— the pa engers among whom the game of shuffleboard is popular."Free lunch" alludes to the American saying "There's no such a thing as a free lunch." In other words, everything costs something and everything has to be paid for by someone; statements otherwise are ploys for gulling credulous people. But free lunch is the order of the day on the U Union②. The president is likewise a fan of NASA's project to establish a ma ed base on the moon and push on to the exploration of Mars;that " aceship" will not be cheap. And the "cash awards" for "all who don't need them" could refer to a host of Bush tax cuts.

布什不是去处理赤字问题，反而在吹捧自己为老年人(也就是喜欢玩推圆盘游戏的乘客)实行的&处方药免费&的政策；免费的午餐暗指美国一句俗语&世上没有免费的午餐&，换句话说，什么东西都有价值，要想得到什么都需要付出，而与此不同的说法则是欺骗那些轻信的人们的花招，可免费的午餐在这艘美国号船上则是常规；这位总统也是一个对美国宇航局在月球建立载人基地以及推进火星开发计划的拥护者———航天飞机可不是便宜的；向&所有不需要钱的人&给予&现金奖励&指的是布什的一大堆减税政策。

From these sweet, bitter, sour objects, sweetness, bitterness, sourness, are abstracted. Once abstracted they can be reapplied;…… For example an emotional experience is associated with the breast, in which the infant feels that there is an object existing independently of itself on which it can depend for satisfaction of its feelings of hunger; assuming a capacity for abstraction, the infant can feel that from the total experience he can detach an element which is a belief that an object exists that can satisfy his needs. The concrete statement might be: a breast exists that can be depended on to satisfy his hunger for food; abstraction from this might be: there is a something that can and does give him what he wants when he wants it. Bion,

从这些甜的、苦的、酸的客体中，甜、苦、酸被抽象出来，它们便可再度被应用；……例如：婴儿有一个与乳房相关的情绪体验，在其中他觉得有一个客体独立于他自己而存在，且可以依赖这个客体来让饥饿感得到满足；如果婴儿有抽象的能力，他就能够觉得从这整体体验中，可以分离出一个元素，此元素是一个信念，亦即，相信一个可以满足其需求的客体，具象的叙述可能是：存在一个乳房，他可以依赖此乳房来满足对事物的渴求；从此抽象出来的则可能是：存在某种事物，当他需要的时候能够且的确会给他那些他想要的。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
