导出了重电子系统在零温度下的比热和磁化率的t线性项，并在费米液体理论的基础上讨论了它们之间的关系。此外，在Kubo公式的基础上，得到了低温下电阻率t2项的严格表达式。结果表明，在没有晶格的自由电子系统中，由电子相互作用产生的t2项的系数由于动量守恒而消失，但它的系数得到了强烈的增强。
T-linear term of specific heat and magnetic susceptibility at zero temperature are derived for the heavy eleCtron systems, and relations among these quantities are discussed on the basis of the Fermi liquid theory. Further, a rigorous expression of the T2-term of resistivity at low temperatures is also obtained on the basis of Kubo formula. It is shown that the coefficient of the T2-term arising from the electron interaction is strongly enhanced though it vanishes because of the momentum conservation for a free electron system possessing no crystal lattice.
