摘　　要：用matlab软件分别模拟了相互垂直不同频率的两个简谐振动在一个周期过程、初相相同而初相位差不同、初相不同而初相位差相同以及初相位差在一个周期变化四种情况下的李萨图,从模拟图上可以看出李萨图的运动轨迹过程,李萨图与两个信号的初相、初相差均有关系,初相位差随时间做周期性变化,合成的李萨图也做周期性变化。Using Matlab software,the Lissajous diagrams of two simple harmonic vibrations with different frequencies perpendicular to each other are simulated under four conditions:one cycle process,the same initial phase but different initial phase difference,different initial phase but same initial phase difference,and the same initial phase difference in one cycle.From the simulation diagram,the motion track process of Lissajous diagram can be seen.The Lissajous diagram is related to the initial phase and initial phase difference of the two signals,and the initial phase difference changes periodically with time,the synthetic Lissajous map also undergoes periodic changes.
