二重积分有关毕业论文

告诉你一个最简单的方法就是用谷歌翻译工具翻译就行

因为对称性啊最后那个部分可以化为=二重积分 (x+y)[h-根号(x^2+y^2)] dxdy=二重积分x[h-根号(x^2+y^2)] dxdy+二重积分x[h-根号(x^2+y^2)] dxdy第一部分关于x的奇函数,区域关于y轴对称所以=0第二部分关于y的奇函数,区域关于x轴对称所以=0所以最后这个就是0如果还需要后面的再给楼主补充~

The second surface integral calculation is a difficulty and key content of higher mathematics. The second curved surface integral, also known as sitting target surface integral, it said the physical significance of the steady flow of incompressible fluid flow to the surface side of the flow. The second kind of surface integral calculation problem is a comprehensive calculus problem, involves the surface side and the normal vector, partial derivative of function of many variables, double integral and triple integrals, the first kind of curved surface integral and gauss formula, and other article, we respectively from two traditional calculation method and an innovative method to calculate the direction of generalizations about the second type of surface integral calculation method, and combined with typical examples illustrate the use of different methods, easy to master by the techniques of.
