Using three moment invariants describing 3-D object reduces data greatly in the model database, this provides a potential solution to 3-D object recognition in arbitrary view.

用三维不变矩来表示三维物体可以极大地减少模型库中的数据量，为从根本上解决任意角度三维目标识别问题提供了潜在的希望。

To determine the condition of chromogenic reaction between iodine and amylum quantitatively, the author studied the law in the course of chromogenic reaction between iodine and amylum with the aid of spectrophotometer quantitatively, and found that maximum absorption wavelength is 610 nm, and the absorbance in the course of chromogenic reaction between iodine and amylum has not changed within 7 hours.

为了确定碘和淀粉反应的定量关系，本文利用分光光度计定量地研究了碘和淀粉显色反应过程中吸光度的变化规律，发现碘和淀粉显色反应的最大吸收波长为610 nm，碘和淀粉显色反应的吸光度在七小时内基本不变，可以进行比色分析。

Some of the safe mobile codes may be rejected to execute, since there is no way to verify statically that the symbol range value of an array subscript expression in PCC.

PCC的数组边界检查存在着由于无法确定数组下标表达式符号值的范围，而造成拒绝执行一些安全的移动代码等问题。本文给出的一种数组边界检查的优化及生成算法，不仅能够比较好地解决了这一问题，同时还生成了循环不变式注解中的条件谓词。

If it turns cold again, they'll dive back down, but then they come out the first warm day.

不一味地等待，这样蚂蚁永远会在气温变暖的第一天出去。

A novel illumination-invariant change detection algorithm based on Cauchy distribution is proposed.

为了更好地进行视觉监视，该文给出了一种新的基于柯西分布的光照不变的统计变化检测算法。

In order to improve the efficiency, an implementing scheme (according to the distribution of strain energy density) was suggested when to consider the fact that the high gradient usually appears only in a very local region, especially in the case of huge amount of computation. All programming has been finished on the platform of commercial codes Mathmatica and Fortran.4. A number of numerical examples and applications were presented to verify the proposed Bezier-Based Element Method. The engineering cases include: the belt die for diamond synthesize, the main frame of wire-rounded press, the hydraulic cylinder of open die forging press. The numerical results show that the BBEM has some good performances.

通过大量的数值算例来考证所构建的各种类型单元，并应用于人造金刚石年轮模具、钢丝缠绕预应力机架和液压机工作缸等实际问题的结构分析；结果表明：所构建的Bezier耦合单元具有描述较大梯度变化场(如位移场、应力应变场等)的能力，该方法不改变单元的大小和形状，保持单元的自由度数不变，而通过调节中间可动节点的位置改变单元内部的场分布，只需少量单元即可较精确地模拟较大的梯度变化；可为有效求解高梯度问题提供新思路，对实际工程应用具有重要意义。

The engineering cases include: the belt die for diamond synthesize, the main frame of wire-rounded press, the oil cylinder of open die forging press. The numerical results show that the BBEM has some good performances. With few elements, the BBEM can lead to a high accuracy. If using same DOFs, the computing precision of BBEM is remarkable higher than that of the conventional FEM.

The results indicated that soil evaporation around barley root was restrained effectively in sunny day when the positive electric field was applied. If the field voltage and interval time are constant, the electric field intensity will be different under the different pole distances, and the effect of boosting plant growth will be different by restraining evaporation and moisture.

试验结果表明：晴天施加正向空间电场可以有效地抑制大麦根系周围土壤水分的蒸发，当电压及间歇工作时间保持不变时，不同异极距下其电场强度不同，表现出的抑蒸聚水促生效果不同。

If you are SEO black hat, then you can say surely, do, be done of course, and we can assure to give a platoon to go to the first you inside a month, and make sure the rank is changeless 2 years, normal word, the enterprise accepts these black hats gladly people service, next black hat SEO people can think in psychology, be in charge of him, money was taken besides, do assorted group what send, let him go up in platoon of a month, when arriving, take service cost, go next person, can last one year as to the rank of his website or be two years that no matter he, father took money to go person, be in charge of his website is dead it is vivid.

假如你是SEO黑帽，那你定会说，做，当然做啊，而且我们可以保证在一个月内就把你给排到第一位，并且保证2年排名不变，正常的话，企业都会很兴奋地接受这些黑帽们的服务，然后黑帽SEO们就会在心理想着，管他的，钱拿了再说，搞什群发什么的，让他在一个月排上去，到时把服务费都拿到，然后就走人，至于他的网站的排名能不能持续一年或是两年那不管他了，老子拿了钱就走人，管他网站是死是活。

In the west, the theory that matter is not continuous but is composed of innumerable tiny particles—eternal, changeless, impenetrable, identical, self-moving, and indivisible—was first clearly stated in the fifth century B.C.E.

在西方，希腊哲学家德谟克利特在公元前五世纪最先清晰地表述了这种理论：物质是不连续的，而是由无数永恒的、不变的、不可入的、相同的、自己运动的及不可分的小颗粒所组成。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
