摘要: 讨论了14MeV中子引起的核反应截面测量中监督反应对测量结果的影响，同时列出了常用的一些监督反应及参数，利用截面的评价值给出了一些监督反应的截面随中子能量变化的关系曲线，并对^27Al（n，p）^27Mg反应做了定性分析，说明了监督反应的选取对反应截面测量的重要性。 It was discussed in this article that the effects of different monitors in the cross section measurements of nuclear reactions induced by 14 MeV neutrons, at the same time some monitors and correlative parameters were listed. The excitation functions of monitors are taken from the evaluatied cross sections, and a qualitative analysis has been performed for ^27Al（n,p） ^27Mg reaction. It indicates that the choice of monitor is very important for cross section measurements
