The chief aim of this study is to investigate the chemical weathering process of the weathering crust in Great Wall Station region of China (in Fildes Peninsula), Antarctica by the method of sedimentology.CW,SW,GW,TW,...The chief aim of this study is to investigate the chemical weathering process of the weathering crust in Great Wall Station region of China (in Fildes Peninsula), Antarctica by the method of sedimentology.CW,SW,GW,TW,WE weathering crusts developed on volcanic clastic rock, gray aptitic basalt with tuff or basaltic bedrock. On change of minerals, geochemical behaviors of elements, migration and enrichment regularities of elements, Correlation between element geochemical behaviors, change of weathering potential of rocks in chemical weathering process are studied by us.We can see that the sequence fo weathering strengths of the abovementioned sections, from high to low, should reflected in TW, GW, CW and SWT and basical correspond with that calculated from the enrichment and differentiation indexes.展开更多
本文以全国3 km三维格点实况降水产品(PTOAS-3km)为检验对比数据,利用DBSCAN(density-based spatial clustering of applications with noise)算法实现降水产品观测一致性检验,利用反距离权重法结合特定的临近站选取策略进行临近站观测...本文以全国3 km三维格点实况降水产品(PTOAS-3km)为检验对比数据,利用DBSCAN(density-based spatial clustering of applications with noise)算法实现降水产品观测一致性检验,利用反距离权重法结合特定的临近站选取策略进行临近站观测一致性检验,运用本站温度、相对湿度进行多要素趋势一致性检验,提出一种基于多源校验的区域气象站降水质控方法,利用大量区域气象站降水数据样本进行检验。检验结果表明:对检验样本中91.8%的站点进行降水质控,具有较好的适应性,尤其对0~8.0 mm以及大于32 mm的小时降水质控效果较好;诊断发现雨量计故障69次,有较强的故障判识能力;但在PTOAS-3km产品缺测较多以及临近站较少的情况下判识能力有待提高。展开更多
