For the cell shown, an electrical current would flow through the metallic conductor and the electrolyte.

对图示电池，有电流通过金属导线和电解质流动。

In the metallic conductor has the electric current passes obsolete must give off heat, thus creates the conductor thermal-expansion, this originally was the atomic condition occurs the change.

金属导体中有电流通过时就要发热，从而导致此导体的热膨胀，使原子的状态发生了变化。

The method of this paper has the following characteristics: 1)any simple or complex fault can be modeled accurately, including metallic short circuit faults and open conductor faults;

这种方法的特点在于：①可精确地模拟各种简单故障和复杂故障，包括金属性短路和完全断相故障；
