The nonlinear ADP crystal is oriented in such a way that phase matched SHG is produced only when both incident beams are present as ordinary rays.

非线性晶体adp的取向是使仅在两束光都存在时才有位相匹配的SHG。

Ordinary cosmic rays are puny things.

普通的宇宙射线微不足道。

Because of their short wavelength, x-rays can pass through objects which are opaque to ordinary light.

由于X射线的波长短，它就能穿透一般光线所不能穿透的物体。
