摘　　要：借助理论方法对凝汽器喉部的内部设备所产生的阻力进行了计算,并根据计算结果对建立小型凝汽器喉部试验装置的可行性进行分析,文中还分别对未布置内部设备的喉部以及内部布置了抽气管和支撑管时的阻力进行了计算,当内部设备的压力损失能够抵消喉部所带来的扩压量,且整个喉部的压力损失量容易被精确测量时,就认为该试验装置具有可行性．This paper studies the resistance by inner equipments of condenser-throat with the method of academic calculation, and does analysis of the feasibility of the mini-condenser-throat experimental equipments according to the result of calculation, in addition, calculates the resistance of throat when there aren＇t equipments and sustaining-pipes in it. If the loss of pressure of the inner equipments can counteract the increase of pressure of the throat, and the loss of pressure of whole throat can be accurately measured, it is considered that the experimental equipments have feasibility.
