摘　　要：分析了汽封间隙对机组振动的阻尼作用及其阻尼系数与振幅的关系。根据分析可知,汽封间隙不仅影响机组经济性,而且对机组振动也有很大的阻尼作用。It is analyzed that clearance of gland seal has damping action to vibration of the unit, and relationship of amplitude and damping coefficient of them is analyzed. According to analysis, clearance of gland seal not only influences economy of the unit, but has very damping action to vibration. 
