This paper focuses on the perturbation which takes the sine form. The effect of amplitude, frequency, wave number, and initial phase difference on the propagation of optical soliton is investigated.

重点讨论了扰动是正弦函数形式时，耦合强度、频率、波数、初始相位差对光孤子传播的影响。

Then, in every situation where the body has an acceleration a, the location has to have this form, where this number is where it was initially, this was the initial velocity of the object.

在任何研究对象具有加速度a的情况下,它的位移就一定具有这种形式,这个系数代表了它的初位移,这个代表了它的初速度
