摘　　要：通过理论计算与模拟验证,分析了有机玻璃支架对堆芯中子场的扰动情况,为窄间隙通道中子注量率测量活化片支架的制作及布置提供了依据,实堆测量结果表明通过合理设计,有机玻璃支架对X堆芯中子场的扰动可降低到较低水平。The disturbance to the core neutron field caused by the organic glass brackets has been studied through theoretical analysis and simulation validation.It provides the basis for the fabrica-tion and arrangement of the activation foil brackets for neutron flux measurement in the narrow.gaps of the core.Measurement in a certain core shows that the disturbance of organic glass brack-ets to neutron field can be reduced to a quite low level by reasonable design.
