                    连续能量蒙特卡罗方法均匀化群常数直接用于堆芯均匀计算,不能与非均匀计算保持反应率和界面流守恒,需进一步处理使其满足等效均匀化原理。本工作研究广义均匀化理论(GET)和超级均匀化方法(SPH)在蒙特卡罗均匀化中的应用,并数值验证简化压水堆堆芯和C5G7基准题。研究表明,GET和SPH的应用提高了蒙特卡罗均匀化群常数堆芯扩散计算的精度,可作为蒙特卡罗等效均匀化方法。
                
                The multi-group constants generated via continuous energy Monte Carlo method do not satisfy the equivalence between reference calculation and diffusion calculation applied in reactor core analysis.To the satisfaction of the equivalence theory,general equivalence theory(GET) and superhomogenization method(SPH) were applied to the Monte Carlo method based group constants,and a simplified reactor core and C5G7 benchmark were examined with the Monte Carlo constants.The results show that the calculating precision of group constants is improved,and GET and SPH are good candidates for the equivalence treatment of Monte Carlo homogenization.
