应用国产FA－1型悬浮空气微生物粒子采样器，对净化手术室与非净化手术室、无菌手术与污染手术在7个不同阶段，3个不同高度等多种条件下，进行手术室空气采样，采用对数线性模型方法对资料进行了统计分析，以了解手术室空气污染的情况和影响因素，提出克服各种影响因素的见解及措施。
Application of domestic FA-1 suspended air microbial particle sampler, the operating room clean room and non-clean room, aseptic surgery and pollution surgery in seven different stages, three different altitudes and other conditions, the operating room air sampling , A logarithmic linear model method was used to analyze the data to understand the situation and influencing factors of air pollution in the operating room and put forward the opinions and measures to overcome various influencing factors.
