本文结合对公共场所旅招业、理发业、影剧院、商场等经常性卫生监督的实践,分析了室内温度、湿度、细菌总数、CO、CO_2等对空气离子化的变动情况。结果表明,空气负离子数与CO_2含量之间存在着非常显著的负相关关系(r=-0.5137、P<0.001),其余项目均无显著的相关关系(P>0.05)。
This paper analyzes the changes of air ionization in room, including temperature, humidity, total bacteria, CO, CO_2 and so on, according to the practice of regular hygiene supervision in public places, such as business trip, barbering, theaters and shopping malls. The results showed that there was a very significant negative correlation between the number of air anions and CO 2 content (r = -0.5137, P <0.001), and no significant correlation was found between the other items (P> 0.05).
