随着汽车保有量的增加(年递增率达到10%以上),汽车排气污染物造成的环境污染情况将日趋严重。所以对汽车排气污染物的监控与防治,已处于刻不容缓的地步。要搞好汽车排气污染物的监控与防治,首先必须做好防治工作。用废气分析仪和烟度计测定排气污染物的浓度,目的是控制排气污染物的扩散,使其限定在被允许的范围内,以达到保护生态环境和自然界生态平衡的目的。
With the increase of car ownership (annual rate of increase of 10% or more), environmental pollution caused by automobile exhaust pollutants will become increasingly serious. Therefore, the monitoring and prevention and control of automobile exhaust pollutants have been put on an urgent footing. To improve the monitoring and control of automobile exhaust pollutants, we must first make good prevention and control work. Using exhaust gas analyzer and smoke meter to measure the concentration of exhaust pollutants, the purpose is to control the diffusion of exhaust pollutants so that they are limited within the allowed range so as to achieve the goal of protecting the ecological environment and the ecological balance of nature.
