摘　　要：研究了巴比妥酸对B Z振荡反应的影响,结果表明,巴比妥酸的加入明显改变了振荡体系的周期和振幅,且巴比妥酸的浓度与振荡周期改变值ΔT及振幅改变值ΔA均呈现良好的线性关系,线性范围为6 4×10-7～3 1×10-3mol/L,相关系数分别为0 9921和0 9954.对振荡体系的扰动机理进行了初步探讨.The effect of barbituric acid on the BZ oscillating chemical reaction was studied.Results show that the adding of barbituric acid can perturb both the oscillating period and amplitude,the changes of the oscillating period or the amplitude are linearly proportional to the concentration of barbituric acid in the range of 64×10-7～31×10-3?mol/L,and the related coefficient are 0992?1 and 0995?4,respectively.The possible reaction mechanism has been explained using the FKN mode.
