摘要
Abstract
Based on unilateral overflow fast thermal equilibrium constant temperature water bath system,pVTt gas flow standard device is designed,and water bath and critical flow nozzle experiments are made.Using the five-way valve combination control technology,air exhaust before functions can be achieved,the pressure fluctuations is reduced.The device balance rime is 6 min.Comparing with other pVTt gas flow standard device,the balance time can be shorten at least in half.关键词
