摘要
建立并用数学软件求解物理实验模型,利用数学软件MATHEMETICA对模型求解,分别得到了在频率比发生微小变化和初相差发生微小变化的情况下,李萨茹图形发生的相应变化,从而得出结论:实验中观察到李萨茹图形的持续变化是由两个相互垂直的方向上振荡的初相差发生缓慢变化造成的。从而结束了教学过程中对相关问题的争论。
In this paper, the experimental model of physics has been built and solved with mathe- matical software, and the Lissa -jou＇s figure has been simulated, To draw the conclusion from this paper that the relationship between Lissa- jou＇s figure and variance of initial phase is tile constant change for Lissa-jou＇s figure was induced by the slow change on variance of initial phase in two vertical dimensions. This conclusion settle the related argument in physic experiment teaching,
