三重积分的计算

摘要

By using the formula ∫∫∫Ωf(x,y,z)dv= ∫R2R1 g(r)4πr2dr, the tripe integrals of some specific functions can be reduced into the definite integral. Meanwhile, some examples are given to illustrate that the calculation of triple integral can be simplified.%对某些特殊函数的三重积分利用∫∫∫Ωf(x,y,z)dv=∫R2R1 g(r)4πr2dr化为了定积分，结合例子说明其可以简化相应的计算。
