【摘要】 通过对某双线电气化铁路隧道内空气细菌污染状况的调查,结果表明,隧道内空气不同程度地受到细菌污染,其细菌数与隧道深度有较强的正相关性,与湿度也有一定的正相关性,与温度(23℃～36℃)有一定的负相关性。指出,隧道内无阳光照射,气温变化小,空气流动性差,阴暗潮湿的环境有利于微生物生长繁殖,并可能影响隧道内作业工人、列车司乘人员和旅客的身体健康。更多还原

【Abstract】 Bacterium pollution in air of a railway tunnel was reviewed. The result indicated that air was polluted by bacterium, and the amount of bacterium had great positive correlation with the depth of tunnel, and had a certain positive correlation with the humidity, and had negative correlation with temperature (23 ℃～36 ℃). In tunnel, there had no sunshine, temperature’ change was small, and the mobile air was little. So the environment was suitable for the growth of bacterium. It was bad for human’s heath.更多还原
