摘　　要：针对船用汽轮机常用的部分进汽结构特点,从叶片不均衡汽流力机理、机组不均衡汽流力受力及不均衡汽流力有利应用三个方面对其进行分析,获得了不均衡汽流力计算公式及某型机组随工况的变化特性,并总结了不均衡汽流力对机组轴承的不利及有利方面,为部分进汽汽轮机设计提供了参考。The unbalanced force of partial-admission for steam turbine is analyzed in this paper. Three procedure of unbalanced force mechanism of blade, unbalanced force of the set and the advantage of unbalanced force are analyzed. The formula of unbalanced force and the different characteristics of it are obtained. The disadvantages and advantages of unbalanced force are summarized. All work is useful for the design of partial-admission turbine.
