The changes of the electron transverse momentum are the basic factors of electron and photon scattering, and their differential scattering sections are decreased with increasing of the quantity of photons which are active with an electron at the same time, and they are quickly decreased with the increasing of the inelastic scattering composition, but their change are slower than that in the situation dominated by laser field.

电子横向动量的变化是引起电子和光子散射的根本原因，其微分散射截面随与一个电子同时作用的光子数的增大而减小，随散射非弹性成分的增大而迅速减小，但比激光场中的情况来得慢一些。

The scattering of the damped electron and photon with the multi-photon nonlinear Compton effect in the high power laser-plasma is studied. Its differential scattering section is also given.

I says,"There's no photon in, it's just that when the electron makes a transition it comes" and he says "Well, where does it come from then, how does it come out?"

我说，"原来并没有光子在内，仅在电子产生转换时，光子才出现。"他又问，那当时它从何处而来的？

The view point about biophoton field elementally belong to a Gaussian field and which was superposed at least by two independent parts of photon emission,one is coherent light field of pure coherent state,another one is chaotic light field which is in heat balancing situ...

提出生物光子场基本上属于高斯场的观点，并认为它至少是由两个独立部分的光子辐射迭加的结果：其一是纯相干态的相干辐射；另一则为混沌态的热光源辐射。
