摘　　要：以自主研制的ZFD-1型中子发生器为例,研究了在不同加速高压下D-D型中子管中子的轴向分布情况,以及影响3He中子监测仪探测性能的一些主要因素.根据所得实验数据拟合图线,可对中子管产生中子的轴向分布进行标定.Taking the ZFD-1 neutron generator as an example,the axial distribution of neutrons in the neutron tube under several suitable acceleration voltages and the key factor that affected the detecting performance of the ↑3He gas-based neutron monitor are studied in the experiment.Some fitting curves and its fitting function are given after processing the experimental data.So that the yield of this（D-D） reaction neutron tube in the neutron tube axial center line is calibrated.
