进一步提出被测元素瞬发γ射线特征峰的面积与其含量的关系式。经实验证明对各常见元素的仪器分析回归值与化学分析值的均方根偏差皆小于０．５ｗｔ％。在铁矿石的分析实验中发现了慢化体的作用，它可明显地提高分析灵敏度。该套中子俘获瞬发γ谱仪对Ｈ瞬发γ峰崐（２．２２３ＭｅＶ）的ＦＷＨＭ为３ｋｅＶ。
The relationship between the area and the content of the instantaneous γ-ray characteristic peak of the measured element is further proposed. It has been proved by experiment that the root mean square deviation of the regression analysis values and the chemical analysis values of all the common elements are less than 0.5 wt%. The role of the moderator was found in the iron ore analysis experiments, which significantly increased the sensitivity of the assay. The set of neutron capture instantaneous γ spectrometer on the H instantaneous γ peak Kun (2.223MeV) FWHM 3keV.
