絆絆坷坷-
The hispaniola herself, a few yards in whose wake i was still being whirled along, seemed to stagger in her course, and i saw her spars toss a little against the blackness of the night ; nay, as i looked longer, i made sure she also was wheeling to the southward
我始終未能脫離伊斯班裊拉號後面幾碼的漩渦，而大船本身好像也在搖搖擺擺地轉變方向，我看見船的桅桿在漆黑的夜幕的映襯下顛了一下，就敢斷定大船也正朝南轉彎。 -
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
在水平分層介質接收函數的波形反演研究的基礎上，本文系統闡述了非均勻介質中彈性波傳播數值模擬常用的三種有限差分方法：顯式差分、隱式差分和交錯網格法，首次將多重網格演算法應用於彈性波方程的數值模擬問題，克服了交錯網格法和顯式差分法穩定性差，以及隱式差分法計算效率低的缺點，大大提高了彈性波數值模擬的精度、穩定性和計算效率。
