【摘要】 机动车排放污染扩散模式可分为高斯模式、经验模式、数值模拟模式和箱式模式。而目前世界各国环保部门推荐应用于污染浓度预测的模式大多属于高斯扩散模式。主要介绍了基于高斯模式的几个主要扩散模型 ,并比较了它们的优劣 ,指出开发新模型需解决的问题更多还原

【Abstract】 The vehicle emission dispersion models can be classified into Gaussian model,empirical model,numerical simulation model and box model.However most of the models used by the environment protection agencies around the world are based on the Gaussian model.Several Gaussian-based dispersion models are introduced and evaluated.Furthermore,the problems to be solved in developing new dispersion models are proposed.更多还原
