diffraction effect meaning in Chinese
绕射效应
衍射效应
衍射作用
Examples
- The dispersion caused from the chromatic aberrations of lens is smaller than that from diffraction effects of it
与衍射效应产生的色散相比，透镜本身的折射率色散很小。 - In order to interpret the experimental results , the radiative transfer theory is modified and the diffraction effects are considered in the modified theory
为了解释这种衍射现象，将衍射效应考虑进辐射传输模型，对辐射传输理论进行了修正。 - To minimize harmful diffraction effects , the secondary , or diagonal , mirror is generally only large enough to let the central portion of the focal plane receive light from the whole primary mirror
为减小不利的衍射效应，副镜，或平面镜的大小只是刚够把主镜在焦平面的像反射就行了。 - The land clutter is useless signals for target detection caused by land terrain . the multipath effect is some kind of interference which is caused by wave reflection on terrain . the diffraction effect is the phenomenon of wave propagation into shadow region
地杂波是由地面散射引起的对目标探测无用的信号;多路径是由电磁波在地面反射所引起的干涉;衍射则是电波绕射传播到遮蔽区的现象。 - It shows that when walk - off and diffraction effects could be ignored approximately estimation of the phase distribution of second - harmonic wave could be done . the far field divergent angle and second moment radius of harmonic wave will vary with the aberration of fundamental wave , but the far field divergent angle will be obviously smaller than that of fundamental wave . the phase distribution of both fundamental and harmonic wave is measured using hartmann - shack wave front sensor in the experiment with 1064nm and 790nm lasers , respectively
这说明利用非线性光学频率变换方法拓宽波前传感器件的响应波段是很难实现的，但是，通常三波相互作用过程的研究均是建立在平面波和理想高斯光束之上，因此我们对于位相畸变倍频过程的研究是非线性光学领域一个重要而有意义的新课题，它有助于人们更加深入理解非线性光学效应，为进一步合理利用之奠定了理论和实验的基础。
