    中文摘要:
          针对活塞有效面积的测量可以根据情况采用直接平衡法或起始平衡法。本文将基于压力形变系数和温度修正的起始平衡法，和与使用直接平衡法获得的测量数据进行比较分析，结果显示不同的活塞式压力计二者测量结果的一致性基于不同的活塞式压力计有所不同。
    英文摘要:
          The effective area of a piston gauge is measured by either the direct balance or the method of initial balance. Herein, by analyzing 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.
