Compared with rectangular chamber, the axialexpansion velocity is small and radial expansion velocity is big in stepped-wall chamber under the same conditions.
和矩形结构相比，同样的工况下，渐扩结构射流轴向速度较小，径向速度较大。

The semi-rigid SSS Clutch design accepts small angular and axialexpansion movements of the adjacent machine shafts to compensate for thermal growth requirements.
半刚性SSS离合器设计接受小角和轴向拓展相邻的机轴运动补偿热增长的需求。
