桂林酸雨中不可溶成份的电镜分析
- ANALYSES OF INSOLUBELE COMPONENTS IN ACICD RAIN OF GUILN BY ELECTRON MIVTOSCOPE
- 摘要：对广西省桂林市1988-03-16-1988-03-29出现的四次系统酸性降水,进行了降水的连续取样和过滤,用电子显微镜观测降水中的不可溶成分,共得到12种元素,即Ar、Mg、Al、Si、P、S、Cl、K、Ca、Fe、Ni和cr.用平均值法和聚类法,分析了桂林酸雨中12种不可溶元素的重量谱特征,以及它们与降水系统之间的关系。
- Abstract：During a period of March l6-29,1988,there were four systeln acidprecipitations in Guilin City of Guangxi Autonomous Region,Rain water sam-ples were continuously collected and filtered for each precipitation process. 12 insoluble components in rain water samplers,i.e. Ar,Mg,Al,Si,P,S,cl,K,ca,Fe,Ni,and Cr were measured by electron lnicroscope. Usingaveraging lnethod and cluster analysis,the characteristics of weight distribu-tions for l2 insoluble elements were analyzed in acid rain of Guilin,And therelation between insoluble colnponents and precipitation system was sorted out.
