摘　　要：实践表明,△P测定仪各部分容积及水银压力计密封端的真空度对△P测值有较大影响,有时甚至因此测不出△P;本文通过理论分析推导和计算机模拟计算对上述影响进行了定量分析,得出了与实践经验相符的结论,并据此提出了应重视的问题。Ap measurements are considerably influenced by the volume of each part and the vacuum of the sealed mercury tube end of the Ap meter, insomuch that Ap measurements are in some cases unobtainable. This influence is quantitatively analysed through theoretical deduction and computer simulation, with results which find good agreement with field observations. Finally, some problems are pointed out for attention
