結果表明，冬季示蹤物偏南夏季偏西北的輸送明顯春季擴散影響范圍最小秋季最大。示蹤物從200km200km模式區域輸出的平均時間去除時間明顯分為冬春季和夏秋季兩組，前者較小，平均在20h以下，後者較大，平均約30h 。不同去除時間出現的頻率分佈是非對稱的，在長去除時間一側，出現頻率下降緩慢，顯示污染物有在該區域內長時間滯留的可能。On fluorescence emission strength of the complex was studied. the reaction of dtpaa with pas - na can give dtpa - pas and dtpa - 2pas. their tb
