摘　　要：各种不同的化学物质可以以不同的方式影响光子发射.实验所用的化学制剂为过氧化氢、硫酸亚铁铵、氢氧化钠、盐酸及乙醇.从光子发射的暂时过程,可以看到两种类型反应.添加过氧化氢或氢氧化钠可导致初始的光子发射增强,以后随时间推移而迅速降低.加入Fe^(2+) K_2Cr_2O_7或乙醇以后则有完全不同的发光动力学过程.V_(79)细胞的超微弱光子发射被认为是整个细胞的一种性质, 实验结果表明, 各种化学物质可以引起光子发射的明显增加或降低,但光谱分布却来看出变化,上述化学制剂的作用仅仅是刺激或抑制光子发射.Different chemical substances may influence the properties of photon emission in different ways. The chemicals used are hydrogen peroxide, ammonium ferrous sulfate, potassium dichromate, sodium hydroxide, hydrogen chloride and ethanol. In the temporal course of the photon emission two different types can be seen. The addition of hydrogen peroxide or sodium hydroxide leads to a high activity at first, followed by a rapid decrease as it lasts. A completely different course of photon emission from V79 cells occurs after the addition of a solution Fe2+, K2Cr2o7, or ethanol.The ultra-weak photon emission from V79 cells can be regarded as a property of the entire cells. Experimental results show that various chemical substances cause a considerable increase or decrease in the photon emission, without changing the spectral distribution to any notable extent, but above chemicals only stimulated or inhibited to produce photon emission.
