进行试验

61In April 1984, the space agency launched a four-ton cylinder carrying experiments to develop new spaceage materials including secret ones for making stealth satellites.

1984年4月，宇航局曾发射过一个4吨重的圆柱体，上面载有对太空时代的新材料（包括用于制造隐身卫星的秘密材料）进行试验的科学仪器。

Go ahead and experiment, try several different kinds. If you would like a detailed description of any of these garlics, just click on the name of the variety. Our garlic is sold by the pound at $16 per pound (assortments, rare varieties or premium/colossal sizes may be more) with a minimum order of one pound.

继续进行试验，尝试几种不同的类型，如果你想详细说明任何这些蒜，只需按一下名字的品种，我们的大蒜售价是由每磅16美元每英磅（ assortments ，稀有品种或溢价/庞大的规模可能会更多），具有最低的秩序一磅。

He could take a community and run it over and over again in different combinations, making ponds without algae, woods without termites, grasslands without gophers, or just to cover the bases, jungles with gophers and grasslands with algae.

他可以选择一个群落，以不同的组合一遍又一遍地进行试验，比如说生成没有水藻的池塘，没有白蚁的森林，没有黄鼠的草地，或仅仅是出于全面涵盖的需要，生成有黄鼠的丛林和有水藻的草地。

Pratham's response to widespread illiteracy and innumeracy was to experiment.

The Viking landers performed experiments to determine the existence of life on Mars.

海盗着陆器进行试验，以确定是否存在火星上有生命。

Several low alloy steels and maraging steel with nearly the same hardness (51. 5HRC) were also chosen in the experiment.

文中又选择了热处理后硬度在51.5HRC左右的几种低合金钢和马氏体时效钢进行试验。

The acceleration mobilities of rotor and fuselage subsystem and coupled system are key parameters for determining natural frequencies of the rotor/fuselage coupled system by using mobility matching method. We have deduced the analytical expressions. In order to verify the feasibilities of the expressions, it is necessary to measure those mobilities.

直升机旋翼和机身子系统以及其耦合系统的导纳是用动柔度匹配法确定直升机旋翼／机身耦合系统固有频率必要的数据，我们已推导了它们的分析表达式，为验证分析表达式的可用性，须进行试验测试与研究。

The measuring process of the impact weighers is analyzed by experiments.

对冲板流量计的测量过程进行试验分析。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
