二重积分的分部积分法

Integration by Parts of Double Integral

重积分是高等数学的主要内容,也是难点内容,其物理意义丰富,应用非常广泛。文章通过对重积分的计算的分析,应用定积分的分部积分法,含参变量积分的可微性及含参变量累次积分的可微性,推导出二重积分分部积分法的相关结论。

As one of the important contents in higher mathematics, multiple integral can be applied in many fields because of its physical background. In this paper, we get some interesting conclusions by analyzing the calculation of multiple integral and discussing the integration by parts and the differential of The conclusions are useful for us to solve the practical problems due to its feasibility. integral with parameters.
