摘　　要：对La3Co的超导转变温度随磁场的变化关系以及比热随温度的变化关系进行了热力学分析,得出了该材料在临界点的热力学临界磁场、吉布斯函数、熵以及比热突变的表达式。The thermodynamic analysis is carried out on relation of superconductivity transition temperature varies with magnetic field and heat capacity with the temperature for La3 Co. The expression which thermodynamics threshold field, Gibss Function, Entropy and changes suddenly to heat capacity in the critical point for this material is obtained.
