摘要
选择太平洋、印度洋、大西洋、北冰洋、内陆丽江玉龙雪山山麓背景降水Ｈ＋、Ｃａ２＋、Ｍｇ２＋、ＳＯ２－４、ＮＯ－３等降水化学组分的背景统计值，研究组分与Ｈ＋的相关性，从而提出定义海洋降水ｐＨ４８、内陆５０为酸雨。
We select the background statistical value of H +、 Ca 2+ 、Mg 2+ 、SO 2- 4、 NO - 3,etc. chemical compositions in Pacific Ocean, Indian Ocean, Atlantic Ocean, Arctic Ocean and continental Lijiang, Jade Dragon Snow Mountain piedmont background precipitation to research the correlation between compositions and H +, thus providing theoretical basis to define ocean precipitation pH≤4 8 and continent precipitation pH≤5 0 as acid rain, and background value is a interval value as well.
