反射器

The assemblies are a direct replacement for older style incandescent bulbs, fitting into the roundel ring as a replacement for the existing roundel, reflector and bracket.

这些组件可直接替换样式陈旧的白炽灯泡，适合于圆玻璃环，可替换现有圆玻璃、反射器和煤气灯。

Satellite retroreflector is used as laser ranging cooperative target to improve the intensity of reflected beam, which has close relationship with processing parameters of the retroreflector.

卫星角反射器作为激光测距系统中的合作标, 其主要作用在于提高地面接收机范围内反射光束的能量密度。

Murphy's primary method will be something called "laser ranging."Light from a laser fired from the Earth could hit a reflector on the surface of the moonbounce back.

Murphy的基本方法将是"激光测距"，从地球上发出的激光打射到设在月球表面的反射器上，反射回地球。
