用法例句

Then the formula of relation between light-wavelength change and tangential and radial velocity of light source is presented and the conclusions listed below are reached: (1)The light-wavelength change is determined together by tangential and radial velocity of light source; (2)Doppler effect is a special case of above-mentioned formula, (3)When the radi.

采用速度矢量分析法,揭示了绝对光速、相对光速和光源速度的关系,给出了光波波长变化与光源的切向速度和视向速度的关系式,并得出如下结论:(1)光波波长的变化由光源的切向速度和视向速度共同决定;(2)多普勒效应是上述关系式的一个特例;(3)当光源的视向速度为0时,光波波长的变化完全由光源的切向速度决定,其切向速度越大,光波的波长越短;(4)当光源的切向速度和视向速度都不为0时,在一定条件下光波波长不变。
