Thus an electromagnetic (EM) wave, travelling at the speed of light has a certain momentum which it will transfer to a reflector, resulting in a tiny force.
加速度的方向跟作用力的方向相同。因此以光速运动的电磁波EM，有一定动能作用于一个反射器，从而产生一个微小的力。
The mobile apparatus comprises a reflector and performs reflection wave transmission by carrying data on a reflection wave for unmodulated carrier.
移动设备包括反射器，将数据加载在与未调制载波对应的反射波上并进行反射波传输。
This paper analyses the coupling wastage in columniform wave guide gas laser, and gives the function between the coupling wastage of laser guide modulo EH11 and the position and radius of reflector.
分析了圆柱形波导气体激光器中的耦合损耗，给出了最低阶波导模EH11的耦合损耗与反射镜位置、曲率半径的函数关系。
