關(guān)于大氣化學(xué)方面的一段翻譯--謝謝。。加急啊

利用2001年1月1日至10日XX市2次霧過程的霧水樣本資料，結(jié)合同期自動氣象站資料，分析了霧水的pH值和化學(xué)成分在在霧發(fā)展過程中隨環(huán)境氣象要素的演變特征。結(jié)果發(fā)現(xiàn)：環(huán)境要素影響污染物的來源，造成酸堿成分比重的變化，進(jìn)而影響霧水的pH值；兩次霧過程霧水的平均pH值為6.53，其中pH<5.6（酸雨標(biāo)準(zhǔn)）的樣本數(shù)占總數(shù)45.1%，均處于第一次霧過程；通過離子間相關(guān)關(guān)系分析表明，兩次霧過程采集到霧水樣本中大量Cl-主要來源于局地污染物。結(jié)合后向軌跡模式分析結(jié)果進(jìn)一步說明輻射霧的發(fā)生主要受局地大陸氣團(tuán)影響；受南面長江水汽影響，將發(fā)展為平流霧；而受東北風(fēng)帶來的海洋氣團(tuán)及附近工業(yè)區(qū)污染物控制影響下的平流霧，離子濃度會大幅度增加。。。 選擇翻譯的英語最純正的，獎勵金幣，謝謝。。。   |

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.

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.
