本文的目的是审查从1920年到1955年35年来在水电站水轮机现场效率试验中使用吉布森法和装置测量水流量的经验记录，并根据可比机组的最大效率表，从总共310个试验中提出图表。并列举了一些不寻常的经历。本文对该方法的准确性作了全面的讨论，特别提到了弗朗西斯Salgat和已故的Dieter Thoma等人的批判性分析，以及在确定用该方法测量水量所需的各种因素时所能期望的精确度。（2）对作者1923年在ASME上发表的原论文作了一些小的修改;（3）一个描绘和计算压差-时间图的数值例子;（4）一个附有注释的部分参考书目。
The purpose of this paper is to examine the records of experience, for 35 years from 1920 to 1955, in the use of the Gibson Method and Apparatus, for measuring the flow of water as applied in field efficiency tests of turbines in hydro-electric power plants.Diagrams based on tables of maximum efficiencies of comparable units, from a total of 310 tests are presented. A few unusual experiences are cited and described. A comprehensive discussion of the accuracy of the method is given; with particular reference to the critical analyses of Francis Salgat and the late Dieter Thoma and others and to the precision which can be expected in determining the various factors required for measuring water quantities by this method.Four appendixes give: (1) A brief description of the Gibson Method and Apparatus; (2) some slight revisions of the author’s original paper published by ASME in 1923; (3) a numerical example of the delineation and computation of a differential pressure-time diagram; and (4) a partial Bibliography with notes.
