By studying the variety of inner structure of stars, an attitude that different demarcation point of stellar evolutional stages can affects the evolutionary track in the Hertzsprung-Russell diagram is developed, based on mass loss rate is a consecutive piecewise function in the stellar evolution calculations. 通过分析恒星内部结构的变化,基于在演化计算中质量损失率公式应采取连续的分段函数的考虑,提出恒星演化阶段的分界点的不同会影响恒星在赫罗图中演化轨迹的观点。
