Based on this analysis we have designed two type lens ducts and the coupling efficiency as high as 84% with quasi CW laser diode array was obtained for ar uncoated lens duct.

基于这种分析，我们设计了两种结构的透镜导管，用激光二极管阵列实验测得未镀抗反膜的透镜导管的耦合效率高达84%。

When a sound wave strikes the spheres at one end of the acoustic lens, the sound gets converted into a type of shock wave known as a solitary wave.

当把声波打击在声透镜一端的球体上时，声波就会转换成称为孤波的某种类型的冲击波。

A "gravitational lens" of this type could be powerful enough to map the continents and oceans of a planet in a distant star system.

这种“引力透镜”足以有力地描绘一个遥远星系中某个星球的大陆和海洋。

Xerox built machines that scanned a printed page of type using a photographic lens, and then printed a duplicate.

She may want to check your eyes and remove the lens for you (and possibly suggest a different type of contacts).
