In the future, power cable nearly becomes the mainpath for the power transmission and distribution, especially in the city and the power user of large scale industry.
特别是在城市及大型工业电力用户，电缆几乎成为今后主要的电能传输、分配的途径。

The size of current path, resistivity, power density are main factors that effect the temperature field and temperature gradient field at crack tip.
试件的通流尺寸、电阻率、导入电流密度是影响裂纹尖端温度场和温度梯度场的主要因素。

And besides, under a large power angle condition, the magnetic field distortion will enlarge air-gap part of the main magnetic path and influence the value of the air-gap voltage ES.
