摘　　要：本文研究了反应堆物理计算中的谱计算的曲率反馈问题。研究了一种实用的作谱计算曲率反馈的方法。通过计算讨论了曲率反馈对谱、少群常数的影响,曲率反馈迭代的收敛情况及谱区划分的影响。该方法已用于HTR-10 MW试验堆的物理设计中。This paper studies the problems about buckling feedback of spectral calculations in physical calculations of the reactor and presents a useful method by which the buckling feedback of spectral calculations is implemented. The effect of the buckling feedback in spectra and the broad group cross scetion, comvergence of buckling feedback iteration and the effect of the spcetral zones dividing are discussed in the calculations. This method has been used for the physical design of HTR- 10MW Test Module.
