Two Gaussian air quality dispersion models, the industrial source complex short-term model (ISCST3) with and without modification have been used to simulate the pollutant concentration distribution in urban areas based on the meteorological data and the emissions distribution of sulfur dioxide. The verified data show that the modified model is more accurate in the urban area of Shijiazhuang. Using the modified model predictions, the control strategies of sulfur dioxide in the urban area have been studied, and the result show that the second long-term (to 2010) strategy can mitigate air pollution significantly and maintain pollution levels within permissible limits. 相似文献

本文就线性L1数据拟合问题证明了熵函数的收敛性，并提出用之求解一类不可微优化问题。同时又说明了此方法当逼近参数较大时参生数值病态，进一步说明指数简单外罚法与熵函数法的等价性。 相似文献
