wavelength plate

A half-transparent plate is put before the microwave detector with its plane perpendicular to the direction of propagation of the microwave. The wavelength of microwave can be determined by moving the plate and the results obtained by this method are the same as by the Michelson interference method.

在微波接收器前放置板面垂直于波传播方向的半透平板，沿波传播方向移动板的位置可以测量微波的波长，测量结果与用迈克耳逊干涉法测量的结果相同。

Multi-wavelength optical signals are led into the drop through two source fibers. CCD image drop analysis can be easily carried out through the removable ring plate.

同时，传感器中通过两路输入光纤引入了不同波长的光信号，通过可拆卸的环形极板便于进行CCD图像液滴分析。

Multiphoton dissociation ( MPD) of tetramethylsilane and two photon resonance three photon ionization of silicon atoms are studied with parallel plate vacuum cell at violet laser radiation in the wavelength range 410~ 404nm.

在410～404nm的紫激光作用下，利用平行板电极装置研究了Si（CH3）4的多光子解离（MPD）及Si原子的双光子共振三光子电离。
