摘　　要：涡轮导向器喉道面积值是燃气涡轮发动机设计和生产中的重要参数，必须加以严格的控制。要有效地控制涡轮导向器的喉道面积，首先必须准确地进行测量。对用水流法测量涡轮导向器喉道面积进行了概述，包括测量原理、方法以及几种测量方法的比较等。The throat area of turbine nozzle which is very important in gas turbine engine's design and manufacture must be controlled strictly. The key for controlling the throat area is how to measure the value exactly. This paper introduces how to measure the area by water flow, including theory, method and comparison with other methods.
