摘　　要：通过分析管道泄漏产生的负压波在传播过程中速度的变化,推导出波速随温度变化的公式,并将管道泄漏点定位问题转化为函数优化问题.在此基础上,提出一种自适应免疫算法,并将该算法应用到输油管道泄漏定位问题上.实际算例计算表明,自适应免疫算法在优化问题中优于遗传算法和常规免疫算法,能有效解决泄漏定位问题.　The velocity change of negative pressure wave generated by pipeline leak during the process of trans-mission is analyzed,the formula of wave velocity changing with temperature is deduced,and the pipeline leak position-ing problem is transformed into a function optimization problem.Based on this deduction,an adaptive immune algorithm is put forward and is used to solve the pipeline leak positioning problem.Actual example calculation shows that the adaptive immune algorithm is superior to both genetic algorithm and normal immune algorithm in solving the optimal problems,and it can solve the leak positioning problem effectively.
