从Friedel求和规则的角度讨论了电子在量子点中的输运。当点中有奇数个电子时，由于电子之间的库仑排斥作用，可能会形成局域磁矩。在这种情况下，可以预测，如果温度低于近藤温度，即，自旋涨落的特征能量除以玻尔兹曼常数。
Electron transport through a quantum dot is discussed from the point of view of the Friedel sum rule. When an odd number of electrons are in the dot, the localized moment may be formed because of the Coulomb repulsion between the electrons. In this situation, it is predicted that the transmission probability of an electron through the dot is almost unity if the temperature is lower than the Kondo temperature, i.e., the characteristic energy of the spin fluctuations divided by Boltzmann constant.
