摘    要：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.

Abstract: Authors studied the silver in galena by means of electron paramagnetic resonance (EPR) for the first time. The results show that there is a fine structure line of the Gauss type in spectrum. Therefore, it is demonstrated that the crystal lattice silver occurs in galena. In addition, authors explained why this line had been generated and computed the concentration of lattice silver by contrasting with the intensity of the fine structure line. So a new method has been provided for studying the occurrence of lattice silver in galena or in other sulfide.
