Subsequently, in August 1949 the former Soviet Union also conducted an atomic test in October years .1952 3, United Kingdom, in February 1960, France, October 16, 1964 China has conducted an atomic test, breaking the U.S. nuclear attack off .1950 10 31, the United States conducted in liquid deuterium to hydrogen fuel for the heat theory test, but a nuclear device is very bulky and can not be used as weapons .1953-year in August, the former Soviet Union conducted in order to solid-state lithium deuteride -6 for the hot nuclear fuel hydrogen bomb test, so that practical hydrogen bomb is possible.

随后，1949年8月原苏联也进行了原子弹试验。1952年10月3日英国、1960年2月法国、1964年10月16日中国先后进行了原子弹试验，打破了美国的核袭断。1950年10月31日，美国进行了以液态氘为热核燃料的氢弹原理试验，但核装置非常笨重不能用作武器。1953年8月，原苏联进行了以固态氘化锂－6为热核燃料的氢弹试验，使氢弹的实用成为可能。

In addition, a new vicinal diol with potential practical value was prepared by asymmetric pinacol coupling reaction under the inducement of substrate.

另外，利用底物诱导的不对称Pinacol偶联反应合成了具有潜在实用价值的新的手性邻二醇。

One is the theory of perturbation based on the inverse scattering transformation, which is essential method in searching the solution of soliton, so it have important academic meaning, however, the method is not easily understood and grasped because of its complicated line of thinking.

逆散射法是求孤子解的基本方法，这种微扰论有重要的学术意义，但它的思路迂回曲折，不太容易理解和掌握，因此实用上并不十分方便。

Rotation matrix s representation with the unit quaternion has no singular points, so the unit quaternion-based estimation method is of more practical importance, and the algorithm in this paper does not need iteration computation compared to those unit quaternion-based method proposed by Horn(1987) and Su, et al.

单位四元数表示旋转矩阵时不存在奇异点，故基于单位四元数的运动估计方法具有更大的实用价值，而本文算法无需Horn(1987)和Su等人(1989)提出的单位四元数方法的迭代运算。

You can browse via a sampler of random colors, each of which throws up a gallery of products -- nice if you aren't quite sure what color you're looking for, or want to randomize your browsing.

你可以浏览一个随机颜色的样本，每个颜色的样本里有一连串的商品。如果你不是确切知道你要找的颜色，或者希望随机浏览的话，这项功能就会很实用。

In this paper, we establish a method to determine the resitivities of the earth and diameter of invaded zone simutaneously,using the deep and shallow apparent resitivitics,and propose a new algorithm. The main advantages of our method is that the selection of the initial value is need not, but in proviously work, it is nescssary and it must close to real values.

成功地解决了由双侧向测井深、浅视电阻率同时反演地层真电阻率和等效侵入带直径问题，建立了可靠的反演算法，此算法的最主要优点在于它不依赖于初值的选取，因而是真正具有工程实用价值的算法。

And the forming limit stress diagram which established with limit stress is independent on the strain paths and it is more convenient and practical to use as the criterion of forming limit under complex strain paths.

以极限应力构成的成形极限应力图不受应变路径的影响，作为复杂加载路径的成形极限判据更加方便和实用。

While the Jeep Wrangler has the "rock-crawler" market locked up as tight as its center differential in four-low, the "expedition" and "trekker" markets are all but ceded to Land Rover, which until very recently has offered larger, more practical, and far more comfortable vehicles to those that want to go not just anywhere, but everywhere.

虽然吉普牧马人的"岩石器"锁定了市场的紧张为中心差分四低，"远征"和" trekker "市场是一切，但割让给路虎，这直到最近提供了更大，更实用，更舒适的车辆，那些想要去的地方不只是，而且无处不在。

This utility can be very useful for finding the origin of unsolicited mail.
