摘　　要：在293-313K温度范围内测定了DyCl3在DMF溶剂中的电导率，求得DyCl3的摩尔电导率值，应用Kohlraush经验规则，使用Origin软件进行线性拟合，作图外推求得DyCl3在DMF中的无限稀释摩尔电导率值，讨论了DyCl3在DMF中的无限稀释摩尔电导率与温度的关系．Determined electrice conductivity of DyCl3 in DMF at 293K to 313K. The use of formula has calculated the molar conductivity of DyCl3 in DMF, and using Kohlraush formula, The use of Origin Software has made the diagram to push outside and calculated the molar conductivity at infinite clilution λ0 of Rare Earths salt DyCl3 in DMF obtained by linear fiting, and discussed influence of the molar conductivity at infinite clilution to the DyCl3 electro- lyte solution with the temperature.
