【摘要】 采用14MeV中子探测物质中氧元素含量是中子活化法判断物质属性的一个重要组成部分。通过氧元素特征曲线可以求出物质中的氧元素含量,曲线上拐点的曲率在一定程度上反映了物质中轻、重元素的含量。采用14MeV中子探测酒精中氧元素含量,得到了一条完整的氧元素特征曲线。通过氧元素特征曲线,结合对氮、氢等元素的分析方法,能够初步判断出物质的爆炸物属性。更多还原

【Abstract】 It is an important part of judging object’s attribute that the oxygen content is detected in material by the neutron activation.The oxygen content is obtained from the oxygen characteristic curve.The other elements can be shown from the inflexion in characteristic curve in a certain extent.It gets an unabridged oxygen characteristic curve by using 14MeV neutron to detect the oxygen content in alcohol.The explosive may be confirmed by uniting the curve and analyse for nitrogen and hydrogen.更多还原
