摘　　要：　生物光子是指活生物体内的(或由生物体发出的 )弱光子. 现在生物光子发射已是人们公认的普遍现象,它的强度在几个到几百个光子 /s·cm2. 生物体内的弱光子起源于体内的非定域的相干电磁场,是受生物体内相干场调节的. 文章介绍了生物光子的非线性、生物体受激发后再发光的双曲线式的衰减过程以及生物光子计数概率的统计分布服从泊松分布和亚泊松分布等实验结果,就生物光子场的相干性及其在细胞通讯、进而在生物调节上的重要作用进行了阐述,从物质结构与光子场相互作用的角度对生物光子的发生及其生物学意义进行了一些讨论.Biophotons are photons within or emitted from living organisms. Biophoton emission (ultraweak photon emission) is now accepted as a universal phenomenon, involving weak light emission from a few up to several hundred photons / s·cm2. Biophoton emission originates from a non-localized coherent electromagnetic field within the living body and is regulated by the field. In this paper an account is given of the coherent properties of biophotons and their functions in cell communication and therefore in biological regulation, based on experimental results concerning the non-linearity of biophoton emission, the hyperbolic decay of reemission after illumination, and the Poisson and sub-Poisson distributions of photocount statistics. From the point of view of the interactions between biological structures and biophoton fields some discussions on the origin of biophotons and their impact are presented.
