Experimental results show that this technique is very precise and useful, and laser speckle method can be used broadly in nondestructive testing field, such as study on surface coarseness, disfigurement measuring, and tiny librations analyzing etc.

由实验检测结果可知这种技术的精度非常高，可广泛应用于表面粗糙度研究、缺陷检测、微振动分析等无损检测领域。

The whole venture seemed SO impractical and foolish that on— lookers called it"Drake's Folly".

可知：德雷克的行为对于那些旁观者来说是多么不现实、愚蠢，被称之为&德雷克愚行&，这与选项C表述得一致。

The results showed that the developmental threshold of egg, larva and immature periods was 12.67, 13.86 and 13.53℃, respectively. It revealed parabola relationship between temperature and both generation survival and finite increase rates. According to the corresponding parabola functions, the optimal temperature for survival and population increase was 30.2 and 33.7℃, respectively, and the optimal temperature range for growth and development of C. maculates was between 30 and 34℃.

结果表明：四纹豆象卵期、豆内幼虫及蛹期、未成熟期发育点温度分别为12.67，13.86和13.53℃；温度与世代存活率及周限增长率均呈二次抛物线关系，根据相应抛物线方程可知，四纹豆象理论最适生存温度和最适种群增长温度分别为30.2℃和33.7℃，其生长发育繁殖的最适温区为30～34℃。

In 2002,I was called to active duty in the Marine Corps in the War on Terrorism.

Modern ways of controlling acceleration and deceleration can be divided into the trapezoidal speed curve and the S-shaped speed curve.

通过对梯形速度曲线与S形速度曲线的比较，可知S形速度曲线在减小冲击和振动方面更具有优势。

According to the results, when the central colors are brown, gray and olive and the subsidiary colors are red, orange, yellow, blue and purple, it is feasible to dye neutral color with two vat dyestuffs.

由实验可知，利用褐色、灰色和橄榄色为主色系，与红色、橙色、黄色、蓝色、紫色等5个辅色系进行两元拼色，基本可以实现对中性色的拼染。
