explicit finite difference meaning in Chinese

显示有限差分法

And the explicit finite difference method , the combining method of the central difference method and newmark s constant average acceleration method , and the transmitting boundary are used . by comparing the acceleration determined by the several methods of the displacements or velocities , a computing method of acceleration employed the one side difference of velocity is more practicality in this research . corresponding to normal incidence of the body waves , p waves or svwaves , and rayleigh surface waves , two two - dimensional finite difference programs are compiled to compu te the dynamic response of two - phase media
以土力学模型为基础，利用以土骨架和孔隙流体的四个位移为基本未知量的数值方法去模拟二维饱水介质中的地震波传播，采用了显式差分方法(中心差分法和newmark常平均加速度法结合)和透射边界，通过比较利用几种差分格式求解的加速度结果，发现一种用速度单边差分求解加速度的方法在本文研究中较为实用，分别编制了体波( p波或sv波) 、 rayleigh面波输入时求解两相介质动力响应的两个二维数值分析程序。
