本文在理论分析的基础上提出了确定Ｅｖ、Ｅｃ值的测试方法，并给出了实测所得的一些数据，使“Ｅｖ－Ｅｃ”通风量计算数学模式的工程应用成为可能。本文还根据实测结果对目前的几秤通风量计算方式进行了比较。
Based on the theoretical analysis, this paper puts forward a test method to determine Ev and Ec values, and gives some measured data to make it possible to apply “Ev-Ec” ventilation mathematical model. This article also based on the measured results of the current several scales ventilation method were compared.
