摘要
寻找Pdx+Qdy+Rdz的积分因子是应用数学领域中极为重要的积分计算方法,同时也是判断一个三维向量场是否为保守场的重要方法。本文给出了一个寻找积分因子的充分必要条件。
It is an important method of integral calculation in the area of applied mathematics to find the integral factor of Pdx+Qdy+Rdz, which is also an important method to judge if a three dimensional vector field is conservative. An sufficient and necessary condition is provided to find integral factor.
