摘　　要：采用MATLAB软件,编制了求解描述二阶PLL非线性捕获的二阶非线性微分方程的程序,计算机自动绘制了相轨迹和时间响应图;求出了二阶PLL的捕获带随初始相差的变化关系曲线。In this paper, MATLAB software is used to work out the computer program for solving the two-rank differential equations which describe the nonlinear capture of the two-rank PLL. The computer then draws automatically the phase trajectory and time response diagram. Finally the diagram is found which shows the variation of the capture belt with the initial phase difference.
