作者首次用电子顺磁共振波谱(EPR)方法,对方铅矿中的银作了研究.在EPR谱图中得到一条Gauss线型的精细结构(FS)谱线,证明方铅矿中有晶格银(Ag~+)存在,同时,论证了FS谱线产生的原因,并用FS谱线相对强度对比法计算了晶格银的浓度,为方铅矿等硫化物中银的赋存形式的研究开创了新路. The authors first studied the silver in galena using the electron paramagnetic resonance spectroscopy (EPR) method, and obtained a Gauss-type fine structure (FS) line in the EPR spectrum to prove that there is a lattice Silver (Ag ~ +) exists. At the same time, the reasons for the occurrence of the FS line are demonstrated. The concentration of silver in the lattice is calculated by comparing the relative intensity of the FS line with the relative intensity. The research on the occurrence of Ag in sulfide such as galena The new road.
