美国新奥尔良的一所微生物研究中心在一项课题的研究过程中无意间发现,微生物的分裂繁殖速率不仅与其所处介质的成分、温度、湿度、压力等条件具有密切的关系,而且与其他一些外界条件,如光、音响等等有着十分密切的关系。光对微生物的影响非常显著,这是众所周知的。例如太阳光中的紫外线对大多数微生物具有很强的杀伤作用,于是人们利用太阳光的照射或人工制造强烈的紫外线来进
In a research project of a subject, a microbiology research center in New Orleans, USA inadvertently discovered that the rate of division and multiplication of microorganisms is not only closely related to the composition, temperature, humidity and pressure of the medium in which it is located, but also to some other External conditions, such as light, sound and so have a very close relationship. The impact of light on microorganisms is very significant and it is well known. For example, the sun’s ultraviolet rays on most microorganisms have a strong killing effect, so people use the sun’s rays or artificially create strong UV light come
