摘　　要：有些三角函数有理式的积分,用传统的万能代换法化为代数有理式积分仍然比较复杂,求积分过程相当困难,有时甚至无法积出.辅助积分法为解决这类三角函数有理式的积分提供了一种新方法和新思路,是传统积分方法的有益补充.It is quite complex to transform some rational formula integral of trigonometric function to algebraic rational integral by using the traditional method of universal substitution,and it is very difficult and sometimes impossible to work out the integral.The auxiliary integral method provides a new method and new idea for solving the integral of this kind,and is a useful supplement to traditional integral methods.
