狄拉克函数 meaning in Chinese

dirac function

When calculating it , the foundation effectness is taken in the controlling differential equation of thick - plate on the elastic foundation , general first the base solveness of the equation is derived by flouier integeral and 8 - function . , then the boundary integeral equation is created by image work theory , finally discret the boundary and the algebraic equation iscreated
在计算弹性地基板时把地基效应归并到弹性地基上中厚板弯曲问题的控制微分方程中。利用广义傅立叶积分和狄拉克函数性质推导出该方程的基本解，继而利用虚功原理建立边界积分方程。通过边界离散，建立代数方程。
