摘　　要：针对已建立的三羧酸循环混合Petri网模型无法获取循环反应过程中各个阶段模型状态的缺陷,使用混合函数Petri网对原混合Petri网模型进行改进,根据改进后的模型提出状态算法,并采用简化模型验证了模型和算法的有效性.结果表明:使用该算法能够依顺序获取反应循环过程的前K个阶段各个库所中物质(即反应物)的量,对监控、研究三羧酸循环等生化循环的反应过程提供了极大便利.The established hybrid Petri net model of Krebs cycle in our preliminary work has a defect,so it is unable to get the model state of each period in the cyclic process.Aiming at remedying it,the original model has been improved with the hybrid functional Petri net.According to the improved model,a state algorithm is put forward and verified by a simplified model.Thus,the capacity of each place,i.e the quality of the reactants,in the first K phases of the cyclic reaction can be obtained and put out in sequence,which helps a lot in monitoring and studying the course of reaction of the Krebs cycle.
