汽车内微环境空气质量检测研究

Study on the measurement of the air quality inside vehicle

汽车内空间小、温度变化幅度大、通风状况不同、行驶和驻车的差异、引擎排放等，使汽车内空气污染的检测涉及的影响因素比较复杂。汽车内空气质量检测可分为静态和动态两种模式。对汽车内空气质量检测，研究探讨了检测温度、平衡时间、通风模式、采样方式、仪器种类等相关因素，提出了关于车内空气污染测试方法的建议。

The measurement of pollution inside vehicle relates to many factors. Because of the small space, temperature easy changed, various ventilation modes, being close to pollution source of engine exhaust, there are differences between in-vehicle and indoor measurement. The evaluation inside vehicle pollution can be classified into two types： static mode and dynamic mode. The influence of measuring factors was investigated. Those factors include temperature, preconditioning time, ventilation modes, engine state and sampling fashion. The measuring mode and relating factors were discussed and the suggestions were offered.
