摘要
从总损耗最小出发，讨论了汽轮机启动的最佳方式—即在最佳应力下的等热应力启动，并根据损伤及优化理论提出了确定最佳应力的方法和最佳应力带的概念。实际启动时，使热应力在最佳应力带内波动。
In this paper, the optimum start-up method of steam turbines is studied from the point of view of minimum loss; The method with which the optimum stress can be determined is suggested and the concept “the optimum stress band” is presented. The total loss will be minimum, if stress fluctuctes in the optimum band during starting.
