压力值是一个普遍存在的物理量,我们在型号研制、生产、试验及使用中的各个环节都离不开压力值的测量。但多年来满以为比较成熟的压力计量,却在科研生产中多次出现差错或量值不一致,例如:八七年一院211厂车间压力表示值和一部提供的压力表示值不一致,相差0.005MPa;八八年在发射现场发现压力表有油,给工程带来麻烦。过去也出现过这类情况。
Pressure value is a ubiquitous physical quantity, we in the model development, production, testing and use of all aspects of the pressure value can not be separated from the measurement. However, over the years, it is thought that more mature pressure measurement has produced many inconsistencies or inconsistencies in scientific research and production. For example, the pressure expressed by No.111 Factory in 1987 and the pressure provided by a pressure gauge are different by 0.005 MPa; in 88 years found on the scene of the pressure gauge has oil, causing trouble to the project. There have also been such cases in the past.
