提出了一种计算电导率的新方法。该方法以弛豫函数或后效函数理论为基础，得到了电导率的一般公式。考虑到观察所需的时间，我们将不可逆性引入到理论中，并研究了该过程的松弛行为，即电导率。并进行了计算，得到了实用的表达式。在微扰近似下，其结果与根据Bloch理论得到的表达式相同。
A new method of calculating electrical conductivity is presented. The method is based upon the theory of relaxation function or after-effect function, from which the general formula for the electrical conductivity is obtained. Taking into account a time required for an observation, we introduce the irreversibility into the theory and investigate the relaxation behaviour of the process, by which the electrical conductivity is. calculated and the practical expression is obtained. In the perturbation ap proximation the result is the same as the expression obtained on the basis of the Bloch theory.
