differential time meaning in Chinese

差值时间

At last , taking advantage of the finite differential time domain method and it ' s perfect match layer absorbcfacient border , we got the energy distribution in a typical micro - disk laser and simulated the radiation between q value and the radius of the micro - disk
最后运用电磁场时域有限差分法( fdtd ) ，采用具有很好吸收效果的完全匹配层吸收边界，研究了典型微盘激光器的能量分布以及微盘的q值随微盘半径尺寸的变化。
Then we analyze the static character of sbs to obtain the sbs gain factor and threshold under continuous wave and pulse . because there is no stokes seed in fiber hydrophone system , we analyze the sbs based on the noise initiation of sbs model . we use the finite differential time domain method to do the sbs numerical simulation in fiber
由于光纤水听器中的sbs是在没有种子光注入下产生的,于是我们推导了噪声激发模型下描述sbs的耦合波方程组,对该方程组使用时域有限差分法进行了数值仿真,并推导了连续光和脉冲光下的阈值。
