发现由于在微脉塞中存在两种腔场模式，导致有两个自由度来改变原子在经过腔场时所受到的势场，因此非简并双光子微脉塞的发射几率的行为不同于简并双光子情况下的发射几率。

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.
