本文对昆明地区农村居室内的太阳紫外线杀菌效果进行了实验研究。结果表明:南向室内的紫外线强度和杀菌效果显著高于北向室。南向室内日照2小时对葡萄球菌及链球菌的杀菌率达90％以上,日照3小时几乎达100％。本实验研定结果适用于与昆明地区纬度及海拔相似的我省中部地区,为我省住宅建筑卫生标准的制订提供了一定的科学依据。
In this paper, Kunming area rural indoor UV disinfection effect of the sun were studied. The results showed that the UV intensity and bactericidal effect in southward direction were significantly higher than those in northward direction. South to indoor 2 hours of exposure to Staphylococcus aureus and Streptococcus sterilization rate of 90% or more, sunshine 3 hours almost 100%. The result of this experiment is suitable for the central part of our province which is similar to the latitude and elevation in Kunming area and provides a scientific basis for the formulation of the hygienic standard of residential building in our province.
