摘　　要：针对三峡水电厂左岸6号机组真机补气试验，研究了补气量的测量，分析了强迫补气对摆 度、振动和水压脉动的影响，讨论了顶盖补气和底环补气对机组开停机的影响，探讨了补气在机组 启动过程中对转轮应力的影响效果。For the test of left bank No. 6 generator unit gas-supply of the Three Gorges Hydropower Plant, the measurement of gas-supply quantity is introduced. Then the effects of compulsory gas-supply on the swing, vibration and water pressure pulse of the generator unit are analyzed. And the effects of top cover compulsory gas-supply and bottom ring compulsory gas-supply on generator unit opening and shutting-down are discussed. The stress change of the runner during generator unit start-up is also discussed.
