implicit algorithm meaning in English
隐式算法
Examples
- Three finite - difference methods , i . e . , stagger grid , implicit and explicit algorithms , are analyzed in detail . multi - grid algorithm is firstly introduced in elastic wave simulation , to solve for the stability problem inherent in stagger grid and implicit algorithm , also for the efficiency problem inherent in explicit algorithm , and the precision , stability and efficiency for simulation of elastic wave arc increased by multi - grid method . phase - delay method is provided to effectively absorb boundary reflection and increase efficiency for wave motion simulation , based on phase delay and amplitude decaying features along wave propagation
在水平分层介质接收函数的波形反演研究的基础上，本文系统阐述了非均匀介质中弹性波传播数值模拟常用的三种有限差分方法：显式差分、隐式差分和交错网格法，首次将多重网格算法应用于弹性波方程的数值模拟问题，克服了交错网格法和显式差分法稳定性差，以及隐式差分法计算效率低的缺点，大大提高了弹性波数值模拟的精度、稳定性和计算效率。
