摘　　要：通过设计并实施一系列环境试验,分析得到了典型被校压力表与数字压力计在不同温湿度环境下的环境影响,为压力现场校准数据修正提供依据和参考,提高现场压力校准的准确度和可靠性。In this paper,we design and implement a series of environmental tests,and obtain the numerical correction coefficients of spring tube type pressure gauges and digital pressure meters under different temperature and humidity environmental conditions. This paper provides the basis for using the calibration data at room temperature,and provides a reference to improve the accuracy and reliability of the field pressure parameters measurement and calibration.
