家庭室内空气中细菌浓度分布之分析

Analysis to the Bacterial Concentration Distribution of Indoor Air.

对家庭室内空气的细菌浓度，在不同时间段的分布进行了研究分析。采用平皿沉降法，测得结果：清晨７：００为强污染时，晚１９：００为弱污染时。并对居室清扫方式提出建议，以促进生存空间的环境质量的改善。

The bacterial concentration distribution of indoor air in different time was studied and analysed.Using sediment plate method,the conclusion was drawn:at 7:00 in the morning it is the serious pollution time,while at 19:00 in the evening it is the weak pollution time.So we proposed to alter the way of cleaning rooms in order to improve the environment quality of the life space.
