Conclusions: The multiple regression analysis may predict unknownvariable from known variables in morphological application.
结论：在形态学上进行多元线性回归分析，可以通过某些已知变量来预测某个未知变量。

By using the Fourier transform, the problem can be solved with a pair of dual integral equations in which the unknownvariable is the jump of displacements across the crack surfaces.
