Important factors include the sampling rate, the zeropoint of pressure sensor, and the correct calibration of sensor, the revised program and algorism may improve the precision of measurement.
如实时设定的实际采样率和压力传感器零点、对传感器校准与标定的正确性等诸因素均可影响实测数据的精度。

Under the assumptation that the "PressureZero Temperature Point" exists, with the corresponding state method, a new vapor pressure equation was established in this thesis.
在假设存在“压力零点温度”的概念基础上，运用对比态的方法，本文提出了一个新的饱和蒸气压方程。
