6. Laplace Transform

The region of convergence is a function that I stick into the integral to make the integral converge.	s平面的收敛区域是一个函数，将这个函数对应的s值带入Laplace Transform，将使得这个积分收敛。
So the region of convergence corresponds to those exponents that makes senses for which the integral will converge.	收敛域对应着使积分（Laplace Transform）收敛的指数（积分中的指数s），
