通过对污染物散发量呈二次多项式或正弦函数变化时通风排害基本微分方程的理论解析,得到室内污染物浓度表达式,供“先导式”通风计算和浓度控制参考。
Through the theoretical analysis of the basic differential equation of ventilation and exhaust emission when the pollutant emission is quadratic polynomial or sine function, the indoor pollutant concentration expression is obtained for “pilot type” ventilation calculation and concentration control reference.
