摘　　要：系统故障演化是受外界影响并不断变化的过程,为研究其耗散性,提出了一种计算演化过程耗散性的方法。首先论述了系统故障演化过程的特征,其次研究了演化的耗散性,最后提出了耗散结构中关键参数的计算方法。结果表明,系统故障演化过程具有复杂的结构和层次,使演化过程满足耗散结构的4个条件;可借助演化过程的物理意义和空间故障网络的数学方法构建关键参数的计算方法,从而定量计算并判断演化过程的耗散性;通过实例展示了分析流程,并得到了预期结果,可为判断和预测系统故障演化过程最终结果对后继事件的影响提供方法。The system fault evolution process is a constantly changing process affected by the outside world.In order to study its dissipation,a method to calculate the dissipation of the evolution process is proposed.Firstly,the characteristics of the system fault evolution process are discussed.Secondly,the dissipation of the evolution is studied.Finally,the calculation method of the key parameters in the dissipative structure is proposed.The results show that the system fault evolution process has a complex structure and hierarchy,which makes the evolution process meet the four conditions of the dissipative structure.The physical meaning of evolution process and the mathematical method of space fault network can be used to build the calculation method of key parameters,so as to quantitatively calculate and judge the dissipation of evolution process.An example is provided to demonstrate the analysis process,resulting in the acquisition of the expected outcomes.The research can provide a method to judge and predict the impact of the final results of the system fault evolution process on subsequent events.
