摘要
汽车在行驶过程中,必然会产生尾气的排放。而在排放的尾气中则有许多污染物能够对环境造成极大的破坏。伴随着县乡车辆的增长以及公路修建的增多,随之而来的则是汽车尾气排放所造成污染物的极速增加,从而导致汽车尾气排放所造成的污染大量增长,机动车排放污染逐渐成为影响环境污染的最大因素。本文以海安市S353部分路段为例,分析大型车不同混入率对公路尾气扩散的影响。
In the process of driving,the vehicle will inevitably produce exhaust emissions.However,many pollutants in the exhaust gas can cause great damage to the environment.With the growth of vehicles and the increase of road construction in counties and villages,the following is the rapid increase of pollutants caused by vehicle exhaust emissions,which leads to a large increase of pollution caused by vehicle exhaust emissions.Vehicle emission pollution has gradually become the biggest factor affecting environmental pollution.In this paper,the influence of different mixing rate of large vehicles on the diffusion of highway exhaust gas is analyzed by taking part of S353 road in Hai'an city as an example.
