摘　　要：讨论了基于射线法测量两相流参数与流体动态变化的关系,推导出由于介质动态变化导致射线计数误差与相含率测量误差的公式,并分析了动态误差与射线源及输油管道直径选择的关系,为利用射线检铡两相流相含率设计方案提供了理论参考。The relation between two-phase flow measurements based on the radiation method and the dynamic changes of fluid is discussed in this paper. An analyzing formulation of the radiating counting errors and the phase volume fraction errors affected by the dynamic changes in two-phase media is deduced, and the relationship among the dynamic error, the radiation source and the diameter of oil pipe is analyzed. As a result, the theoretic reference is established for the scheme designs of two-phase flow measurement using radiation method.
