| 摘 要： | 用气相色谱法对学校几种教室空气中ＣＯ２浓度分别进行了测定，结果表明上课时教室空气中ＣＯ２浓度显著高于室外空气（Ｐ＜０．０１），与通风状况有密切关系。另外，ＣＯ２与室内负离子浓度有一定的负相关性。

| Abstract: | The CO 2 concentration in classroom air was determined by Gas Chromatography The result showed that the CO 2 concentration in classroom air was significantly higher than that in the outdoor air( P <0 01) It closely related to ventilation A negative correlation between the concentration of CO 2 and negatively charged ion was presented |
