Along with increment of mean photon number, there is no change in the oscillation period of the squeezing curve, but its scope increases obviously and its stability begins to reduce; when the mean photon number and the field mold structure fixed, the speed of moving atom has a great infection on the extent and period of the radiation squeeze. With the speed of moving atom increasing, not only the complete squeezing effect would be archived, the stability would also enhance.
随着平均光子数的增加,压缩曲线的振荡周期没有明显的变化,压缩曲线的振荡幅度明显增大,压缩的稳定性变小;在平均光子数和场模结构参数一定时,原子运动速度对光场压缩的深度以及压缩周期影响程度较大,增大原子运动速度,不但可以实现完全压缩光场,而且压缩的稳定性得到提高。

Rotational modes are independent of the transverse support stiffnesses of the carrier, ring gear, and sun gear. Translation modes are similarly independent of the rotational support stiffnesses. Large contact ratio do not mean lower mesh force. If either the number of sun or ring gear is not multiple of planet gear, system will run effectively, with lower impaction of tooth mesh in and out.
