This paper describes the short pipe and cross head aerating test to the draft tube when the model turbine has HL250 model runner, of Francis type, meantime, flow steadying flats test in conical section of the draft tube was made. The results and relative data obtained in these tests have been analysed. The test is carried out on new high head hydraulic test stand of HRILEM by means of . specil air admission test apparatus which can achieve two test mode conveniently, i.e. natural aerating test and forced aerating test. Step method for the results from model test to prototype herein try to have a discussion.

本文对HL250转轮进行了模型吸水管的短管和十字架补气试验以及锥管稳流片试验,并对试验结果和有关数据作了分析。试验是在哈尔滨大电机研究所新建的高水头水力试验台上用专门的模型补气试验装置进行的,这种装置可以方便地实现自然补气及强迫补气两种试验方式.最后还对模型试验结果的换算作了探讨.

In this paper,all formulas for measuring plane dimension error in a close way are derivedin sequence.The application of these formulas is illustrated by giving examples. This studycontributes to a ne.w method for flat testing and offers a theoretical basis for revising statestandards on plane dimension and flat testing rules.

本文按顺序推导出封闭法测量平面度误差的全部计算公式,并举实例说明它的应用。该项研究为平板检定提供了一种新方法,并为修订平面度国家标准和平板检定规程提供了理论依据。

In this paper,formulas for calculating the flatness error and its uncertainty on the minium condition principle are derived in detail and the algorithmic program for this calculation isalso worked out. The application of these formulas is illustrated by examples. This paper isreferential value for flat testing.

本文详尽推导出,按最小条件判别准则求平面度误差及其不确定度的计算公式,以及电算程序。并以实例说明它们的应用,该文对平板检定具有参考价值。
