[交流] 关于大气化学方面的一段翻译--谢谢。。加急啊

利用2001年1月1日至10日XX市2次雾过程的雾水样本资料,结合同期自动气象站资料,分析了雾水的pH值和化学成分在在雾发展过程中随环境气象要素的演变特征。结果发现:环境要素影响污染物的来源,造成酸碱成分比重的变化,进而影响雾水的pH值;两次雾过程雾水的平均pH值为6.53,其中pH<5.6(酸雨标准)的样本数占总数45.1%,均处于第一次雾过程;通过离子间相关关系分析表明,两次雾过程采集到雾水样本中大量Cl-主要来源于局地污染物。结合后向轨迹模式分析结果进一步说明辐射雾的发生主要受局地大陆气团影响;受南面长江水汽影响,将发展为平流雾;而受东北风带来的海洋气团及附近工业区污染物控制影响下的平流雾,离子浓度会大幅度增加。。。


选择翻译的英语最纯正的,奖励金币,谢谢。。。

The evolution chatacteristics of  pH value and chemical components of the fog along with enviromental and meteorological factors changed during the processes of fogging were anlysised by combining the fog sample data in the two fogging processes of XX city from Jan. 1st to 10th, 2001 and automatic weather station data over the same period.
The results showed that enviromental factors exerted an influence on the sources of pollutants which chenged the proportion of acid-base composition, thereby influenced the pH value of the fog; The average pH value of the fog in the two fogging processes was 6.53 in which the numbers of samples that have a lower pH value than 5.6 (acid rain standard) accounted for 45.1%. All of these samples (pH<5.6) were from the first fogging process.
The results of correlation analysis between ions indicated that chloride ion in the samples of the two fogging processes mainly comed from local pollutants.
Combined with back-trajectories mode anlysis results, it was further manifested that occurrence of radiation fog was mostly influenced by local continental air mass. It would be developped into advection fog by the affect of Yangtze River steam in the south.And its ion concentration would be greatly increased under the influence of marine air mass brought by the northeast wind and pollutants control in the neighbouring industrial areas.

Keywords: weather station; pollutants;

We analyze the evolution characteristics of pH value and chemical composition of fog,  that is how to change with the environmental meteorological factors in the process of development.
We make use of some city’s two times fog process sample data from January 1 to 10 in 2001 and the automatic weather station statistics in the same time.
The results showed: Environmental factors influence the sources of pollutants, resulting in the changes in the proportion of acid to base composition, thereby affecting the fog water pH;
In the two-time fog, average pH value of the fog water is 6.53, and the pH value<5.6(acid rain standard) is accounted for 45.1% of the total, are in the process of the first fog;
Based on the correlation between ions, analysis indicated that the large number of Cl- in the fog water samples that collect from the two-time fog are mainly from local pollutants;

Combined the analysis of the back trajectory model, the results further explain the occurrence of radiation fog is mainly affected by local continental air mass;
It will form  advection fog if affected by moisture south of the Yangtze Rive;
and advection fog formed that under the control of  the northeast marine air mass and contamination comes from the nearby industrial area , in which the concentration of ions will significantly increase.

Keywords: weather station; pollutants;
