摘要
测量活塞有效面积可以根据具体情况采用直接平衡法或起始平衡法。本文就基于压力形变系数及温度修正的起始平衡法与使用直接平衡法的测量数据进行比较分析,结果显示二者测量结果的一致性在不同的压力量程段有所不同。
The effective area of a piston gauge is measured by either the direct balance or the method of initial balance. Herein, by analy-zing and comparing the measurement of direct method and the other method which makes material pressure distortion coefficient and temperature compensated, it is found that the results of the two methods are different based on the different types of piston gauges.
