我们考虑一个由二维电阻组成的电子网络。每个电阻器都有一个电压降的阈值，低于这个值它就会成为绝缘体。如果阈值是随机分布的，则流经整个网络的电流与外部电压不成正比。电流与电压之间出现了一种新的非线性关系。
We consider an electrical network of resistors in two dimensions. Each resistor has a threshold value for the potential drop below which it becomes an insulator. If the thresholds are randomly distributed, the current flowing through the total network is not proportional to the external voltage. A new nonlinear relation between current and voltage appears.
