| 摘 要： | 以天然形成的方铅矿晶体为研究对象,说明方铅矿远红外反射光谱中低频端Plasmon反射边产生的物理原因,并根据不同反射边的斜率(Va)值大小与样品中所含杂质量的相关性,以解释不同样品中不同组分和结构上的特点对Plasmon反射边的影响。且根据不同杂质的正负相关性在自然成因上的因果关系,证明从反射光诸结构中获得对矿物成因有一定指导意义的信息的可行性。

| Abstract: | The natural mineral galena (PbS) samples are studied in this article. The physical reasons of plasmon reflectance edge in low-frequency are discussed. According to the relations between the slope of plasmon reflectance edge and the amounts of natural impurities, the influence of different chemical composition and crystal structures in different samples to the plasmon reflectance edge are explained, and according to the positive and negative corelations among the amounts of different impurities in samples on the cause and effect relations of natural formation, the feasiblity of obtaining information from far infrared reflectance spectral structures for indicating the mineral formation conditions is disscussed. |
