【摘要】 通过可控间隙活塞式压力计与自由形变活塞式压力计的比对实验,复现了高压自由形变活塞式压力计的形变系数。实验结果和理论计算存在较大的差异,自由形变活塞式压力计在高压力下有效面积的准确度受形变系数的影响非常大,因此对于其形变系数的不确定度需重新评估和进一步研究。

【Abstract】 The paper recurrences the high pressure balance distortion coefficient by comparison experiments between controlled-clearance piston gauge and free deformation pressure balance. There exists great difference between the results from experiment and calculation. Under high pressure the accuracy of effective area of free deformation pressure balance is affected by its distortion coefficient very much,therefore the uncertainty of its distortion coefficient needs to be reevaluated and further researched.
