noise pollution of the environment

Noise is transient; once the pollution stops, the environment is free of it.

另处，物理性污染没有后效作用，即噪声不会残存在环境中，噪声停止，污染立即消失。

Aerogine has the features of high rev, heavy air flux and high exhaust temperature, fierceness of noise engenders environment pollution largely during aeroengine test.

由于航空发动机转速高，空气流量大，排气温度高，试车时产生的强烈噪声形成大范围的环境污染；

The pollution of the environment includes the air pollution, water pollution, garbage wastes contaminative, the soil pollution is contaminative with the noise pollution.

环境污染包括大气污染，水污染，垃圾废弃物污染，土壤污染和噪声污染。
