中文摘要: 本文建立了凝汽器在真空严密性试验工况时排汔压力的动态数学模型，分析了凝汽器真空下降速度与漏入空气量之间的关系，并对真空严密性试验的工作程序提出了修改意见．
Abstract:This paper raises the dynamlc mathematical model for vacuum pressure of condenser during turbine vacuum dropping test, and analyses the relationship between air leakage flow and vacuum dropping speed during test. Lastly it proposes the rational modification for nowadays regulation of vacuum dropping test.
keywords: condenser exhaust pressure vacuum dropping speed
