摘　　要：从粒子密度和粒子流密度出发,分析了几类相关的算符,讨论了它们的性质与相互关系;从具体的物理意义出发,明确了合适的粒子密度算符和粒子流密度算符的表达形式.The related operators of several kinds are analyzed and their nature and reciprocity are discussed from the particle and granule current densities. The appropriate forms of the particle density and granule current density operators are determined according to the concrete physical significance.
