摘要
分析了拍图形的对称性与分振动的频率比n1/n2 及初相Ψ1、Ψ2 之间的关系 ,导出了不同的Ψ1、Ψ2 (0 ,π ,±π/ 2 )与Δn(Δn =n1-n2 为奇数或偶数 )的配搭情况下的拍图形对称性规律 ,得出了拍图形对称性决定于Ψ1、Ψ2
The relation between the symmetry of the beat figures and the frequency ratio n 1/n 2,the initial phases Ψ 1?Ψ 2 of the component of vibrations is analyzed.The symmetry rule of the beat figures is derived in case of different combinations of Ψ 1?Ψ 2(0,π,±π/2) and Δn(Δn=n 1-n 2 is odd number or even number).It is concluded that the symmetry of the beat figures is dependent on Ψ 1?Ψ 2 and Δn.
