酸雨

Acid precipitation is another important forest disturbance in China.

酸雨是我国森林生态系统健康的又一重要影响因子。

All the pollution is not acid rain, i.e., sulphuric and nitric acid dissolved in precipitation .

酸雨为含有硫酸和硝酸的雨，它并不是造成污染的唯一原因。

The resultant precipitation —— acid rain is a dilute mixture of sulphuric acid and nitric acid.

由此产生的沉降物——酸雨是稀释后的硫酸和氮酸的混合物。

Introduce of actual acidification velocity(H~+ produced) for evaluating the acidifying effects of soil tested,only the stimulated acid rain with pH2.5 could lead to soil acidifying,however,acid rains with pH≥3.5 played a buffering role to soils tested,with the weakening of soil acidity.

引进土壤的实际酸化速率H产生+值衡量供试土壤的酸化，只有pH2.5的模拟酸雨淋溶促进了土壤的酸化，而pH≥3.5的模拟酸雨处理对土壤的酸化具有一定的缓冲作用，且土壤酸度减弱。

Abrupt changes in available K resulted from the falling of fine tephra of the YTT eruption, and its abnormal zone about 1 meter thick implied that the fine tephra of the YTT eruption falling in wide provenances of loess was secondly carried with eolian dust into the loess Plateau of China by the East Asian winter monsoon during the early stage of the last glacial period.

固定铵的异常主要记录了YTT事件所产生的酸雨沉降，速效钾的异常则是由于YTT微细火山灰尘在黄土剖面及其广阔的物源区伴随酸雨沉降的结果，厚达1m的异常带表明末次冰期冬季风逐渐强盛和南移的过程。

Nothing was said, for example, about the impacts of acid-rain controls on regional coal-mining employment or customers electric bills. Nor were the benefits of acid-rain controls reported in ways that members of Congress or the public could understand.

如这一计划丝毫没有提到酸雨控制给地区性采煤工业就业率所带来的影响以及对广大消费者用电费用的影响，也没有向国会议员和公众报告酸雨控制所带来的益处。

The effect of lanthanum on the germination, MDA content and peroxidase activity in sorghum seeds under acid-rain stress were investigated. The objective of the study was to develop a scientific method and technical guide for mitigating acid-rain damage on seed germination.

本文以高粱&熊杂9号&为对象，采用模拟酸雨伤害的常规种子实验方法，研究稀土镧对酸雨胁迫下高粱种子萌发及过氧化物酶活性和丙二醛含量的影响。

This indicates that La probably decreases membrane lipid peroxidation induced by acid-rain through POD activity adjustment, which eventually alleviates acid-rain damage on seed germination.

上述结果表明， La可通过调节POD活性减轻酸雨胁迫引发的膜脂过氧化，缓解酸雨对种子萌发的抑制作用。

Environmental Monitoring Station of Wuhu City, 241000, Wuhu, Anhui, China Abstract: Acidrain is one of the most serious environmental poll ution problems ,To resolve its chemicalcomposition and its rule of seasonal change will be hel pful in researching the cause ofacid rain and the method of acidification contr ol .

芜湖市降水化学成分特征及变化趋势的初步研究王小月张书贵摘要：酸雨是我国严重的环境题目之一，对其化学成份及其四季变化规律的分析、研究将有助于酸雨成因的探讨和酸化控制的研究。

This paper is a part of the "Studies on characteristics of acidrain subsidence and its prevention,"adout the weather feature in Qingdao area. It lays emphasis on both boundary layer pollution meteorological characters and acid causing substance sources.It points out that boundary layer has special nature in Qingdao.

青岛地区酸雨成因研究表明，青岛市近代工业发展排放大量致酸物质、海洋上天然排放的二甲基硫是重要的原因；青岛地区边界层风场和温度场的特殊规律是形成酸雨的另一个重要原因；江淮气旋和黄淮气旋大型天气形势起了辅助作用。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
