摘　　要：动态刻棒方法基于逆动态方法,通过引入静态空间因子(SSF)和动态空间因子(DSF)改善测量精度。采用堆芯三维稳态和瞬态计算模拟测量过程,得到空间因子。在某研究堆上开展了动态刻棒方法试验验证,结果表明动态刻棒方法具有较高的测量精度,具备取代传统方法的能力。An advanced rod worth mesurement technique, the dynamic rod worth measurement method（DRWM）has been developed. Static Spatial Factors（SSF） and Dynamic Spatial Factor（DSF） were introduced to improve the inverse kinetics method. The three dimensional steady and transient simulations for the mesurement process was carried out to calculate the modifacation factors. The rod worth measurement test was performed on a research reactor to verify DRWM. The results showed that the DRWM method provided the improved accuracy and could be a replacement of the traditional methods.
