“人民军医”1957年二月号刊载了蒋美庭同志写的“关于不同类型水井容水量的几种测量方法的介绍”一文。作者在文中采用水柱的平均直径乘水深得出一个圆住体,用这个圆柱体来代替井水的实际体积——平截圆锥体。因此,我认为,作者应告诉读者,这个表达式是一个近似值,倾斜角越小越准确。这个方法得出的结果比实际容水量要小,这 “People’s Military Medical ” February 1957, published by Comrade Jiang Meiting, “Introduction to Several Methods for Measuring Water Capacity of Different Types of Wells”. In this paper, the author uses the average diameter of water column by water depth to obtain a circular body, using this cylinder instead of the actual volume of well water - truncated cone. Therefore, in my opinion, the author should tell the reader that this expression is an approximation and the smaller and more accurate the angle of inclination. The result of this method is smaller than the actual capacity of water
