摘要
本文详细论述了开放式气室的结构与性能，二氧化碳浓度数据采集系统、物理性能等。并重点介绍了作者自行研制的ＯＴＣ－Ｉ型开顶式气室。
OTC- 1 open top chamber is made by frame, wall , filter , air-blower , ventilate tube,CO2 density control system and data automatic collection system. At design, the ventilatedway was advanced, and made experiment gas in the chamber well-distributed , the distribution of meteorological elements in different chambers is closed , and the differences of environmental efements inside and outside the chamber is smaller. The QGS-08 infrared programmer controller has full functioqand operated easily.
