| 摘 要： | 早在十九世纪中期,英国化学家Robert Angus Smith就报道发现了酸雨,但当时并未引起人们的注意,直到欧洲的酸雨对生态环境产生严重危害,酸雨这一自然降水才得到人们的关注,随之对它的研究也有了很大发展。我国起步虽然较晚,近几年发展较快,有关的研究报导逐年增多。目前,对酸雨判别基准pH值的确定还处于争论之中,英国许多专家都主张pH小于5.0的降水为酸雨,本文仍以原来的基准值pH=5.6为标准,就日常生活中经常接触到的下雨这一自然现象,介绍一下天然降水与酸雨的区别,并分析酸雨的形成与人类对大气造成的污染的联系以及酸雨给人类带来的危害,从而告诉大家应当保护我们的环境。

| Abstract: | In the middle of the nineteenth century. British chemist Robort Angus Smith found acid rain, but at that time,little attention was paid to it until acid rain did a great damage to the ecological sys-tem in Europe. The people took account of it and the much research was done in this field. The research have a short history in China but it develope rapidly in recently years. The reports about it are increasing year in year our. So far, the matter in dispute is the determination of standard of acid rain's pH. Many American scientists maintain that the rainfall of pH<5. 0 is acid rain. This paper basde on the original norm to introduce the difference of acid rain and the natural rainfall which is viewed in the life. It analyses the contaction between the formation of acid rain and the air
pollution which is caused by human being and analyses acid rain do people harm. Finally,it points out that people should protect our ecological system. |
