【摘要】 <正> 本工作采用仪器中子活化分析法测定黄海及东海大陆架海底沉积物中的28种元素,研究了两个海区沉积物中元素的分布及背景值。所用测量仪器为SCORPIO 3000程控γ谱仪,Ge（Li）探测器灵敏体积136cm³,能量分辨率1.87keV(对⁶⁰Co的1332keV γ射线)。实验结果表明:更多还原

【Abstract】 The instrumental neutron activation analysis is applied to the multi-elemental analysis of the surface sediments taken from the cold water eddy of Yellow Sea and the continental shelf of East China Sea. The distribution and origin of 28 elements are studied, and the natural background values of some trace elements discussed.更多还原
