precipitation acidity

The results showed that acidity of precipitation is influenced by SO 2 and alkalescent dust.

结果表明：抚顺市的降水酸度是由大气中的SO2等酸性气体和碱性尘埃共同作用的结果，降水pH值向酸性降水发展。

It is believed that the pollution caused by ground sources only has local and ajustable effects on the acidity of precipitation, and the fundamental reason causing regional acidifying of precipitation is maybe that regional acid atmospheric layer exists in strato sphere.

地面源污染是造成该区局部降水酸度差异的调节因素，而造成全区降水酸化的根本原因是存在于平流层的区域性酸化大气层。
