摘　　要：存在于活的生物系统的超弱自发光子辐射,是生物分子从高能态向低能态的跃迁所发射的光子。根据Frhlich理论,活的生物系统是一个高度有序、高度相干性的开放系统,其运动状态具有内部协同作用的集体效应,并可看作许多同类振子的集合,当振子因某种原因处于激发态后,其必然会跃迁回基态,从而发射出光子。可导出此过程遵守Sine-Gordon方程,是典型的孤子方程,说明生物光子在活的生物系统中的传播具有孤子特征,使生物光子能成为生物系统信息的良好携带者,可以通过对生物光子的测量而获得生物系统内的信息。由于弱激光的作用,可将生物振子激发到激发态,处于激发态的分子。将跃迁到低能态,并发出光子,此过程有弛豫效应,并导出相关公式。Spontaneous photon emission was produced by the transition of the living biological system from upperstate to low-lying state. According to Frhlich＇s theory, living biosystem is an extreme coherence＇s open system. The motion state possesses a collective vibration effect and the biosystem can be regarded as a set of vibrators with same character. The transmit equation of biophoton in biosystem was deduced. This is a typical Sine-Gordon equation. It showed biophoton has soliton character in the living biological system. In conclusion, biophoton can be an ideal carrier of biosystem information. Furthermore, the interaction of weak laser photon with biomolecule system is discussed in this work. It shows that weak laser irradiation can excite the biologic vibrator from excited state to lower energy state with relaxation phenomenon and photon emission.
