摘要
在互相垂直的两谐振动频率成整数比 ( m∶ n)的情况下 ,得到其合振动轨迹一般方程 ,由此得到李萨如图形由分振动振幅及 mψ2 — nψ1确定 (ψ1,ψ2 为两分振动的初相位 ) ,并得出李萨如图形关于ψ1或ψ2变化的周期。
Under the condition of two frequency of simple harmoric vibrations which are perpendicular to each other form ratio of whole number(m∶n),the author obtains the general equation of the trajectory of composite vibration and prove that Lissajous figuer is determined by the amplitude of separate vibration and mψ 2-nψ 1,and more obtains the period of Lissajous figure on the initial ψ 1 or ψ 2.
