MODEL SIMULATION AND DATA DISPLAY OF THE DISPERSION OF METHANOL AND FORMALDEHYDE FROM METHANOLGASOLINE FUELLED AUTOMOBILE

摘要：对使用甲醇-汽油燃料的汽车尾气排放中甲醇和甲醛进行了场地测定.设计了模拟甲醛和甲醇在大气中扩散的高斯模型,编写了程序并计算了来自各点源和线源的排放浓度.将所得数据进行图象显示,绘出等浓度图.结果表明,应用甲醇-汽油燃料不足以造成对公路旁环境的威胁.

Abstract：Unburned methanol and formaldehyde in exhaust emission of a methanolgasoline fuelled automobile were tested. A Gaussian-type model was used to simulate the methanol and formaldehyde dispersion in the air. The pollutant concentrations caused by the emisions from both point and line sources were calculated using this model. Concentration contour maps based on either measured or calculated data were plotted. The results obtained suggest no significant threat to ambient air quality from the application of methanol-gasoline fuel.
