摘要
论文指出对多元积分作适当(退化\平移\线性\非退化的非线性)变换,改造被积函数(或被积表达式),可以简化其计算.本文给出多元积分直接化为单积分命题和平移坐标系不改变多元积分值命题.
The author proposes that a suitable（degenerate／translation／linear／non-degenerate nonlinear） transformation can reform differential form of multi-integral so as to simplify the calculation of the integral.In the paper,transforming muti-integral into definite integral directly and translation of coordinate system to simplify calculation of integral are introduced.
