In this paper, the author gives the concept of the translatable symmetry and apply it to multivariate function differential calculus, double, triple, and then a simple method o f calculating differential coefficient and integral is deduced by the unified form. Finally, the author introduces the method to use translatable symmetry to calculate several examples.%本文首先给出轮换对称性的定义,将它应用于多元函数微分学、二重积分及三重积分的计算中,用统一的形式归纳出计算微分、积分的简易方法,最后用轮换对称性计算了几个例题.
