针对系统在线稳态优化中对关键输出变量相对稳态的判定要求，基于假设检验提出了一种样本数据稳态判定方法，该方法能实现隔离型热管换热节能系统中数据稳态判定．同时，利用现场数据进行实验研究，所选数据总体服从正态分布，通过判断样本数据的方差变化完成数据稳态判定，得到优化周期大于4min的结论．

英文摘要：

For the determination meth hypothesis testing steady-state identification of the key variables in the steady-state optimization, a od was proposed for the steady-state identification of sample data based on the The method could realize the data steady-state identification of the isolated heat-pipe heat exchange system. Then, experiments were carried out by the practical data with normal distribution characteristics. The data steady-state was determined by judging the change of sample variance. Finally, it was found that the optimization cycle must be greater than 4 minutes.
