integral transformation

基本解釋

在具體計(jì)算中，由于應(yīng)用積分變換以及將多重?zé)o窮求和化為單一無窮和，極大地簡化了計(jì)算，節(jié)省了計(jì)算時(shí)間。
The layer stiff matrix, which expresses the relation of force and displacement on surface of every layer, could be calculated to apply integral transformation.
通過積分變換的方法可以求出每一層表面處位移與力之間的關(guān)系，進(jìn)而形成層剛度矩陣。
In present research on fracture dynamic problems, Laplace or integral transformation was generally used, and numerical methods had to be adopted to solve the loop integral.
在現(xiàn)有斷裂動(dòng)力學(xué)問題文獻(xiàn)中，一般采用拉氏變換與積分變換方法，得到的回路積分最后還需借助于數(shù)值方法求解。
