摘　　要：在两种不同溶剂条件下 ,研究了 5种α ,α′ 二氧代烯酮环二硫代缩酮类化合物的紫外光谱特性。在同一种溶剂条件下 ,比较含氮化合物与含硫化合物的紫外光谱特性 。The characteristics of ultraviolet spectra of five α,α′-dioxoketene cyclis,s,s-acetals (N,N-acetals) have been studied in different solvent,on the basis of last paper .And the character of ultraviolet spectra of sulfur-containing compounds and nitrogen-containing compound was compared in the same solvent, the changing rules with the change of chemical stucture have been indicated.It is specially important that the character of such as this conjugated system was studied,however it almost did not do before.And the this can used in studies afterwards.
