论文摘要
静态扩展系统起始体积中封闭的气体压力的精确测量对于实现低测量不确定性很重要。这项工作着重于阀门关闭过程和产生的压力差。流量保护定律用于建立模型，并开发了实验程序来研究整个移动阀板的压降。评估各种参数并将其与实验数据进行比较。
The precise measurement of the pressure of the gas enclosed in the starting volume of a static expansion system is important for achieving low measurement uncertainties. This work focuses on the valve closing process and the resulting pressure difference. The flow conservation law is used to set up a model and an experimental procedure has been developed to investigate the pressure drop across the moving valve plate. Various parameters are evaluated and compared with experimental data.
