Solving Inverse Transformation By Using Combined Method Cleverly

求拉普拉斯变换及其逆变换,是《工程数学》的难点,组合求逆法,将原逆变换与辅助逆变换组合起来,大大简化了逆变换的结构式,运算起来简便易行。

It is a difficulty to solve Laplace's transformation and inverse Laplace transformation in Engineering Mathematics. A new method is introduced here in which the original inverse transformation is combined with the auxiliary inverse transformation,thus making the structure of the inverse transformation greatly simplified and the operation easier.
