The above results were interpreted by the calucation of CNDO/2 method of quantum chemistry. The effection of a collector-accelerating-agent mixed with a just main-collector was better than that of two collectors mixed. The structure of collector-accelerating-agent is described:① a carbonic chain or ring compound with a polar-radical,② a larger positive electric centre in this polar-radical〓 was the compound with many coordination atomics.

量子化学CNDO/2方法计算验证了上述结果，并且得到如下结论：选择有效的捕收促进剂与适当捕收剂混用，比用两种捕收剂混用更有效；并总结出捕收促进剂的结构特点为：①带一个极性基团，有足够疏水性的碳链、环化合物；②极性基因中有一个较大的正电荷中心；③极性基因中最好有多个能参与配位的极性原子。
