The results indicate that multisource fatigue core appear in the axe surface non-metallic inclusion distributing place by bending and retortion circle stress; The crack selevtivity expand to form the fatigue step along inclusion distributing route in the cut stress; The crack celerity expand to form the fatigue striation when puff part adequacy long in the positive stress.

结果表明：辊轴在弯曲、扭转循环应力作用下，表面非金属夹杂物分布位置出现多源疲劳核心；在切向应力作用下裂纹沿夹杂物分布路径选择性扩展构成疲劳台阶；当断面张开部分足够长时，在正向应力作用下发生快速扩展，微观形成疲劳辉纹。

A test model of four co-rotating disks was developed as the simplified version of a typical internal cooling system of a gas turbine compressor. The investigation was on the distribution of local heat transfer coefficient and the averaged nusselt number of the downstream main disk. Experimental analysis may lead to following conclusions: the distribution is not of monotony and multi-peaks were found along the disk surface,Nu increases with the decrease of the rotational reynold number Re(subscript w,Nu increases with the axial reynold number and the grasholf number.

针对航空发动机多级压气机盘腔的冷却问题，对具有轴向通流的三腔模型进行了系统的研究，通过对局部换热特性与平均换热特性的分析，可以表征旋转盘的热应力水平和相对冷却效果，结果表明表征旋转盘热应力水平的局部换热特性在旋转盘的半径上呈多峰分布，表征相对冷却效果的平均换热特性与旋转雷诺数Re、进气雷诺数Re以及格拉晓夫数Gr有关，当Re及Gr增加时，平均努塞尔数Nu随之增加，而Re的增加使之减小。
