| 摘 要： | 由于流速仪法测流具有测量精度高、数据可靠和使用范围广等优点，因此而成为水电站机组效率试验中经常被采用的测流方法之一。本文以圆形管道为例，论述了其数学模型的建立，并根据该测流法的特点编制了相应的数据处理计算机软件。最后将大溪河水电站１￣＃机机组效率试验的实测数据输入计算机进行了实例计算，计算结果证明该电算软件具有较好的实用价值。

| Abstract: | Due to high precision and reliability of current-meters flow measurement,it has been usedfor unit efficiency test of hydropower station quite often. This paper discusses how to set up the math-ematic model of current meter measurement in circular pipo and the appropriate program was developedusing FORTRAN Ianguage. Finally, the real measured data of Daxi River hydropower station werecomputed and good result was given. |
