| 摘 要： | 针对高压汽水两相流实验中小液量测量困难这一问题，运用重力压差主要由液相密度决定的原理，提出了由圆管内重力压差变化线性分求流量的方法，实验表明这一方法线性度很好，本文对这一方法进行了理论分析，得到了计算修正公式，同时评估了计算带来的误差。

| Abstract: | Aimed at the problem of small flux measurement in high pressure stem-water test,considering gravity pressure difference (GPD) is mainly determined by liquid density, a method ofgetting flux from GPD chsnge is given. Test proved that the method's linear degree is good. In thearticle,the method is analysed in theory first,then correlation formula is determined and deviation isevaluated. |
