【Abstract】 For nonlinear composite stiff impulsive differential equations,explicit Euler method is used to solve the non-stiff part,and implicit Euler method is used to solve the stiff part.Then Euler splitting method is obtained,and the stability and convergence of the method are studied.The correctness of the obtained theory is verified by numerical experiments.It also shows that this method can significantly improve the computational speed.更多还原
