It can get the three-dimensional profile of the object surface effectively. Because of the cragginess of the three-dimensional surface when sine grating is projected the image of the sine grating is modulated and the modulated image is taken by a CCD camera with an angel compared to projecting direction. After the phase shift measuring method, the phase is gotten. Because the phase is calculated by the phase shift measuring ranges from –π to +π it isn't continuous. The phase unwrapping is necessary to recover the continuous phase about the object shape.

这种方法采用结构光照明，将正弦光栅图像投影到被测物体表面，用与投影方向成一定角度的CCD摄像机获取受物体表面面形调制的变形光栅像，根据数字相移算法计算出相位分布，由于从相移计算的相位被截断在反三角函数的主值范围内，因而是不连续的，必须通过相位展开恢复出连续相位分布，由相位－高度关系最终求出物体轮廓的三维数据信息。

Being a microcosm himself, he discovers — and it is a true discovery, and he is the man to make it — that the world has been eating green apples; to his eyes, in fact, the globe itself is a great green apple, which there is danger awful to think of that the children of men will nibble before it is ripe; and straightway his drastic philanthropy seeks out the Esquimaux (16) and the Patagonian,(17) and embraces the populous Indian and Chinese villages; and thus, by a few years of philanthropic activity, the powers in the meanwhile using him for their own ends, no doubt, he cures himself of his dyspepsia, the globe acquires a faint blush on one or both of its cheeks, as if it were beginning to be ripe, and life loses its crudity and is once more sweet and wholesome to live.

他是大千世界里的一个缩影，他发现，这是一个真正的发现，而且是他发现的，——世界在吃着青苹果；在他的眼中，地球本身便是一只庞大的青苹果，想起来这却很可怕，人类的孩子如果在苹果还没有成熟的时候就去噬食它，那是很危险的；可是他那狂暴的慈善事业使他径直去找了爱斯基摩人、巴塔哥尼亚人，还拥抱了人口众多的印度和中国的村落；就这样由于他几年的慈善活动，有权有势者还利用了他来达到他们的目的，无疑他治好了自己的消化不良症，地球的一颊或双颊也染上了红晕，好像它开始成熟起来了，而生命也失去了它的粗野，再一次变得又新鲜又健康，更值得生活了。

The electronic heating evaporator in the high-side gravity recirculation system in ANSI/ASHRAE 64-2500 standard is replaced by a new type plate evaporator which is more effcient and energy-saving, because the cold water outlet from the evaporator that is used to heat the cryogen can be used once again to cool the air in the air inlet trunk; an air processing unit is designed in the lab design, so to imitate all kinds of weather in each season in every location of China at any time the test is being made; the data selection system can send all the data in the test to the computer at one time, and to reduce the cost of the test some data which is more stable are read manually through traditional meters if this can not sacrifice the precision of the test.

本文的设计中用效率更高的新型板式换热器代替了原ANSFASHRAE 64——2500标准中压缩驱动循环系统中的电加热蒸发器，加热冷剂后得到的低温淡水还可以用于冷却进气通道中的空气，不仅提高了效率，而且更加节能；实验室方案中增加了空气处理系统，可以实现随时对全国各地各季节的空气状态进行模拟，方便实验的进行；采用数据采集系统将数据整体采集到电脑中方便数据处理，而且对于变化频率不高相对较为稳定的数据采取传统仪表进行人工读数，在保证测试结果准确性的前提下降低了成本。

Chaikin algorithm is the simplest discrete curve modeling method.In thepaper planar Chaikin algorithm is generalized into sphere,and the practicability ofthe algorithm as well as the continuous differentiable property of the generatingcurve is proved.It is shown that the curve generated by Chaikin algorithm is apiecewise spherical Bezier curve of second kind of order two.Furthermore,generalspherical corner-cutting algorithms are discussed,and it is pointed out that thecurve generated through corner-cutting has"Spherical Variation DiminishingProperty".3Curve interpolation method restricted on a smooth surface based ontransformation.

Chaikin算法是最简单的离散曲线造型方法，文中将Chaikin算法推广到球面，证明了算法的可行性和生成曲线的连续可微性，指出球面Chaikin算法得到的曲线是分段的二次第二类球面Bezier曲线，并给出了用球面Chaikin算法构造球面插值曲线的算法；进一步，文中讨论了一般的球面割角算法，指出由球面割角算法得到的曲线具有"球面变差缩减性质"。3基于变换的约束在光滑曲面上的曲线插值方法。

This route overcomes the shortcoming on environmental pollution and poison in the cyanide process, which is widely applied in our country. This route isnt known in our country. It is a new environmental pollution process, and is in according with the progress of industrial policy. In the second step, the methyl isobutyl ketone which introduced in the patent is replaced by the material A, and the marketable foreground of the byproduct is considered. It is an innovated process, which can supply a gap in our county.

文中探讨的工艺路线克服了国内所广泛采用的氰化法路线所带来的环境污染和人体危害问题，目前国内尚未有报道，是一条新型的环保路线，符合国家产业政策的发展方向，而且在第二步3-氨基丙醇的合成中，用原料A取代专利中介绍的甲基异了酮，在获得产物的同时又兼顾了副产物的市场潜力，工艺上具有创新性，可填补国内该工艺路线的空白。

Since is nation don't need check product, such honor, beyond all doubt is because three deer companies must own very complete examination organization and means, and let the nation trust, that since it is so, we can guess and affirm, now that be subjected to impossibly surprised of"pollution", that is to intentionally add three chlorine cyanotype An, if is so, that circumstances severity, even can calculate previous for the sake of business enterprise benefits cupidity smoked under the heart of premeditated murder, for the sake of lane pure why three deer companies want to intentionally add three chlorine cyanotype An products that the poison harms a baby kid, we understand first once what is three chlorine cyanotype An

既然是国家免检产品，如此荣誉，毫无疑问是因为三鹿公司本身一定就拥有相当完备的检测机构和手段，并让国家放心，那既然如此，我们可以猜测和认定，既然不可能是受到了意外的"污染"，那就是故意添加了三氯氰胺，如果是这样，那事态就严重了，甚至可以算得上一种为了企业利益利欲熏心下的谋杀，为了弄清为什么三鹿公司要故意添加毒害婴幼儿的三氯氰胺制剂，我们先了解一下什么是三氯氰胺

Let F=LF be a s-closed local formation such that every minimal non-F-groups is solvable. It is proved that 1 If every cyclic subgroup of of order 4 and every minimal subgroup of G are contained in, then G is a F-group. 2 If there exists a normal subgroup N of G such that G/N∈F and every cyclic subgroup of N of order 4 is weakly c-normal in G and every element of N of prime order is contained in Z(superscript f subscript ∞), then G is a F-group.

设F=LF是一个子群闭的局部群系，满足每个极小非F-群是可解群，证明了：1如果G的任意极小子群和任意4阶循环子群都含于Z中，那么G是F-群；2如果存在G的正规子群，使得G/N∈F，且N的任一4阶循环子群在G中弱c-正规，N的任一素数阶元含于Z中，那么G是F-群。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
