旅客列车车厢内空气质量影响因素的研究进展

Research progress on influencing factors of air quality in carriage of passenger train?

旅客列车车厢空气质量影响因素与列车的车型、季节有关。不同车型车厢内的空气质量影响因素不相同,不同季节各项指标合格率亦不同,空调列车内环境质量优于非空调车。非空调车噪声合格率低于空调列车,不同车型噪声合格率不同。作者综述了影响车厢空气质量的12种因素。

The influencing factors of air quality in carriage of passenger train are related to type of train and season. The influencing factors of air quality in carriage are distrinct in different types of train, and the qualified rates of various indexes are distrinct in different seasons. The environmental quality of air-conditioned train is better than that in train without air-conditioning. The qualified rate of noise in train without air-conditioning is lower than that in air-conditioned train, and there is difference in qualified rate of noise between different types of train. The paper summarizes 12 factors that influence the air quality in carriage.
