integral transformation

基本解释

In the calculation of the DGF, it is simplified by using the integral transformation and replacing the multi-infinite summation with a single one.
在具体计算中，由于应用积分变换以及将多重无穷求和化为单一无穷和，极大地简化了计算，节省了计算时间。
The layer stiff matrix, which expresses the relation of force and displacement on surface of every layer, could be calculated to apply integral transformation.
通过积分变换的方法可以求出每一层表面处位移与力之间的关系，进而形成层刚度矩阵。
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.
在现有断裂动力学问题文献中，一般采用拉氏变换与积分变换方法，得到的回路积分最后还需借助于数值方法求解。
