波形松弛(WR)方法是一种在时间域内分析非线性动力系统的迭代方法。该方法在每次迭代时将系统分解成几个动态子系统，每个子系统在整个给定的时间间隔内被分析。给出了WR方法收敛的充分条件，并给出了在MOS数字集成电路中的例子，表明这些条件在实际应用中是非常温和的。理论和计算研究表明，该方法是有效和可靠的。
The Waveform Relaxation (WR) method is an iterative method for analyzing nonlinear dynamical systems in the time domain. The method, at each iteration, decomposes the system into several dynamical subsystems each of which is analyzed for the entire given time interval. Sufficient conditions for convergence of the WR method are proposed and examples in MOS digital integrated circuits are given to show that these conditions are very mild in practice. Theoretical and computational studies show the method to be efficient and reliable.
