摘　　要：汽轮机内湿蒸汽两相流中一次、二次水滴的参数和流场是密切相关的，但国内外迄今没有能同时测量这些参数的技术和设备。作者成功研制了能同时测量湿蒸汽两相流中一次、二次水滴和流场的集成化探针。该探针已在３５０ＭＷ汽轮机上进行了实测。本文介绍了该测量系统的原理和构成。In the two phase wet steam flow of steam turbine, the parameters of fine and coarse water droplets and the flow field are closely correlated, however, until now no techniques and devices are available to measure all the parameters simultaneously. The authors have successfully designed and made an integrated probe system for this purpose. Experiments have been done in a 350MW steam turbine.
