space charge field meaning in English
空间电荷场
Examples
- And some relevant property parameters of waveguides are measured . based on the band transport model , the buildup of space charge field and the light - induced refractive index changes in photorefractive crystals are discussed
首先根据带输运模型的动力学方程组，讨论了光折变晶体中光致空间电荷场的建立以及由此而产生的折射率变化。 - ( 3 ) we explore photorefractive screening solitons and characters of beam transmission in sbn : 61 : cr crystals . the dependence of beam diameter at the crystal output face on applied field is presented . and influences of the limiting space charge field of the crystals on the experimental results are analyzed
( 3 )初步研究了两块不同掺cr浓度的sbn 61 cr晶体中的屏蔽型空间孤子效应，以及不同外加直流电场作用下光束在晶体中的传输，给出了晶体出射表面处光斑直径随外电场的变化曲线，并分析了晶体中空间电荷场的饱和效应对实验结果的影响。 - The effects of the higher - order terms on the self - deflection process of photorefractive bright solitons in a crystal are also investigated . compared the results of first - order diffusion term acting alone with both the first - order diffusion term and the higher - order space charge field terms acting together , the screening solitons always bend right , whereas for the self - deflection of the photovoltaic bright solitons and the screening - photovoltaic bright solitons both bending right or left is possible , and it is possible that no self - deflection process occurs
然后考虑到高阶扩散项和高阶电荷场对明孤子的影响，发现当外电场很强时，与只考虑一阶扩散项作用的结果相比，屏蔽明孤子的偏转量会增大，而光伏和屏蔽光伏明孤子的偏转量有时会增大有时会减小，在一定条件下也会消失。
