摘　　要：重力注硼系统不仅设备简单、经济，而且具有固有安全的特点。本文采用一组双组分两相流体五方程式描述系统的物理过程，分析影响注硼速度的因素。分析结果说明：在所关心的范围内，反应堆压力容器内不凝结气体的分压力和注硼管直径的影响最大。In this paper, a simple, economic, and inherent safe system-boron gravity. injecting system in heating reactor is introduced. Its physical process and the factors influencing on boron-injecting velocity are analyzed with a five-equation set which includes 2-phase and 2-component. The analyzed result shows that in interested area,both the partial pressure of incondensable gas in RPV (reactor pressure vessel) and the diameter of injection pipe are the main factors influencing on boron-injecting velocity.
