摘要
文章从理论上分析了确定李萨如图形形状的确定因素,以及李萨如图形的对称性和周期性,并利用Matlab软件对李萨如图形进行了计算机模拟,全面、形象地研究了李萨如图形的特点,认为李萨如图形的形状由分振动振幅、频率比和cos(m1φ2-m2φ1)确定,并具有对称性和周期性。
The decisive factors for the shape of Lissajous figure,the symmetry and the periodicity of the Lissajous figure are analyzed theoretically in this paper.In addition,computer simulations about Lissajous figure are performed with Matlab.The features of Lissajous figure are studied allsidedly and vividly.
