【摘要】 在用变量替换方法处理多元函数积分学中的某些问题时,习惯上都采用数学分析的方法;它山之石可以攻玉,变量替换的代数方法——正交变换法,也是处理多元函数积分学中某些问题的行之有效的方法。更多还原

【Abstract】 When some problems in plural - function integral calculus are treated in a variable substitute way, it is customary to employ a mathematical analytic method. However, the algebraic methodof variable substitute ——positive intersecting transformation is also an effective way to deal withsome problems in plural-function integral calculus.更多还原
