Abstract
In the choice of period verification methods,if the measurement standard required higher accuracy,comparative transmission and method of mean values should be adopted firstly.Otherwise,comparative measurement method could be adopted.This paper describes the period verification methods on Static Expansion Vacuum Standard、Gas Micro-FlowStandard Apparatus and Vacuum Gauge Calibration System.
