An optical system with refraction and total internal reflection was proposed according to the luminous characteristic of LED and the law of energy conservation. The ordinary differential equations satisfying the spots on the contour curve of TIR refractive and reflective planes were established. The coordinates of points on profile curves were obtained by solving these ordinary differential equations using Runge-Kutta method. The profile curves were acquired by curve fitting of the coordinate spots with software UG, and then TIR model of the projector and data of the surface shape suitable for NC manufacture were obtained.

根据LED的发光特性以及能量守恒定律选择采用折射全反射光学系统，通过建立TIR折射面及全反射面轮廓曲线上的点所满足的常微分方程，利用RungeKutta求解常微分方程得到轮廓曲线上点的坐标，再在UG中对坐标点进行曲线拟合得到轮廓曲线，进而得到TIR模型及适合数控加工的面形数据。

A represents the labeled fragments as position control; H1 represents the human H1gene as positive control; NEG represents the 431 bp fragment of bacterial 16s RNA as negative control; X,Y,Z,R,T,U represent the uncharacterized genes of SARS virus, which functions are unknown, the number under the parenthesis represents the position of each gene on the virus genome.

其中A表示利用已经标记好的片段作为坐标点；H1为人H1基因cDNA片段，作为芯片杂交的阳性点；NEG表示细菌16sRNA的一段长431bp片段作为芯片杂交的阴性点；X，Y，Z，R，T，U为推测的蛋白编码区，其功能还不清楚，括号内数字表示在基因组上的相对位置。

The most objectionable misuse of quotation marks, but one which illustrates the dangers of misuse in ordinary prose, is seen in advertising, especially in advertisements for small restaurants, for example "just around the corner," or "a good place to eat."

最令人反感的滥用引号的例子可以在某些广告里找到（这很能说明日常文字里滥用标点是多么容易），尤其是那些小餐馆的广告，例如&拐角就到&、&吃饭的好地方&等等。

If you are a Mac user you will immediately recognize the type as apple default font, but Helvetica also pops up on sightposts, shop windows and even in high fashion, it's totally ubiquitous and its fifty years old this year, and if you are wondering what the point or the fourteen point, even punctuating such an event is, well one film maker has made a whole documentary telling the whole story of Helvetica, digital planet's own man of letters Peter Price has been to see the movie, and as he now reports.

如果你是麦克用户，你会马上意识到这种字体是苹果默认字体，但是Helvetica也出现在标示牌上、商店的窗户上，甚至非常流行，几乎是随处可见。到如今，这种字体已经有50年的历史了。如果你还不知道点或十四点是什么，甚至不知道标点这类事情，那么一个电影的制作商已经把整个Helvetica的故事编辑成一部纪录片，它将告诉你整个过程。《数字平台》节目的记者彼得·普爱斯看过此部电影，以下就是他所报道的。

Textual Criticism of the ancient books includes punctuating, annotating, complementing and many other jobs. This book deliberates on the common types of mistakes, ways to detect problems, collating methods, how to take collatin motes, and points for attention, etc. Basing on his own rich experience over the years, and combining Mr. Cheng Yuan's collating methods with his own , the author presents us a detailed exposition of the important role textual criticism plays in sorting out ancient books, and the ways to do the collating job satisfactorily.

校勘士籍包括标点、注解、辑佚等多方面的工作，本书从古书讹误情况、如何发现问题、校勘方法、如何作校勘记、校勘注意事项等诸方面，根据自己多年的实际经验，并结合陈垣的校勘方法，对校勘在古籍整理中的作用、如何作好校勘工作作了系统详尽的论述。

The Latin, Greek, and Cyrillic alphabets, for example, are naturally broken down into letters, digits, diacritics, punctuation, and a few special characters like the space, which can all be arranged in simple linear sequences (although processing them requires adding rules about how certain sequences, such as a letter followed by its diacritics, are interpreted—this is not within the scope of a character repertoire).

例如拉丁、希腊和斯拉夫字母表自然分为字母、数字、变音符号、标点和如空格这样一些少数特殊字符，它们都能按照一种简单的线性序列排列（尽管对它们的处理需要另外的规则，如带有变音符号的字母这样的特定序列如何解释——但这不属于字符表的范畴）。

First, sequential tomograms of the hip are obtained from a CT scan; secondly, an accurate and automatic method is used to extract the profile of the acetabulum; thirdly, a hybrid method is utilized to gather fiducial marks on the acetabulum; fourthly, bulky error sampling points are removed. Finally, an ellipsoid fitting method is used to fit the ellipsoid model of the femoral head. Two male sufferers with different necrosis extents are chosen as experimental subjects for contrastive simulation.

首先利用一种精确的自动分割方法在髋骨部位CT序列图像中提取髋臼轮廓；然后使用基于等距栅格采样法与辐条式采样法相结合的混合采样法得到髋臼凹面的空间坐标点集，并剔除其中的误差采样点；最后采用基于二次曲面一般方程的方法拟合原始股骨头椭球面模型。

These four steps, rechecking your spelling, taking care with punctuation, watching for fundamental grammar errors, and rewriting, will improve your writing.

这四个步骤，复查您的拼写，标点照顾的，看的基本语法错误，并重写，将改善您的书面答复。

Whether Mr Jagdeo's vision ever materialises depends not just on the UN's deliberations over punctuation, but also on the willingness of powerful players like the European Union to abide by emissions goals that keep the price of carbon high.

至于Jagdeo总统的计划能否实现，并不是仅靠联合国改变标点符合就能做到的，而是要取决于欧盟等掌权者是否有意实现他们的排放目标，继续将碳价维持在高位。

Often, the first step is correcting mechanical errors such as incorrect punctuations or spellings

首先要纠正它的一些无意识的错误，譬如错误的标点或拼写等。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
