光学仪器中的光学零件生霉起雾是一种很普遍的现象。特别是在热带和亚热带及沿海广大地区更为显著。我国长江以南的气候环境最适宜霉菌的繁殖。因为霉菌生长,主要靠霉菌孢子、营养物质、合适的温度和湿度这四个基本条件。当湿度为80～100％,温度为20～35℃时霉茵最易生长。光学仪器在这 Optical parts in the optical mildew fogging is a very common phenomenon. Especially in the tropics and subtropics and the vast coastal areas are more significant. The climatic environment south of the Yangtze River in our country is most suitable for the breeding of molds. Because mold growth, mainly by mold spores, nutrients, the appropriate temperature and humidity of these four basic conditions. When the humidity is 80 ~ 100%, the temperature of 20 ~ 35 ℃ when the most susceptible to growth of mold Yin. Optical instruments here
