摘　　要：　在298K时测定了NdCl3在混合溶剂(DMF和H2O)中的电导率,根据Λm=(λ液-λ剂)×10-3/c公式求得NdCl3的摩尔电导率Λm值,应用Kohlrausch经验规则:Λm=Λ∞m(1-βc),使用Origin软件进行线性拟合,作图外推求得NdCl3在混合溶剂(DMF和H2O)中的无限稀释摩尔电导率Λ∞m=300.01(S·cm2·mol-1).Determined electrice conductivity of NdCl_3 in DMF and H_2O at 298K.The use of formula Λ_m=(λ_液-λ_剂)×10^(-3)/c has calculated the molar conductivity of NdCl_3 in DMF and H_2O, and using Kohlrausch formula Λ_m=Λ~∞_m(1-βc), The use of Origin Software has made the diagram to push outside and calculated the molar conductivity at infinite clilution λ~∞_m = 300.01 (S·cm^2·mol^(-1)) of Rare Earths salt NdCl3 in DMF and H_2O obtained by linear fiting at 298K.
