补充资料：电场
| 电场 electric field 电荷或变化磁场周围空间里存在的一种特殊形态的物质。电场的基本特征是能使其中的电荷受到作用力，电场是电作用的媒递物。电场具有能量、动量，但不具有静质量，场和实物粒子可以相互转化。电场是在一定空间区域内连续分布的矢量场，描述电场的物理量是电场强度矢量，可以用电力线形象地图示。静止电荷产生的电场称为静电场或库仑场。静电场的高斯定理表明它是有源的，电荷是场源；静电场的环路定理表明它是非旋的，可以引入电势描述它。随时间变化的磁场产生的电场称为有旋电场，它的高斯定理和法拉第电磁感应定律表明它是无源有旋的。普遍情形的电场是静电场和有旋电场之和。电场和磁场是紧密联系的，变化的电场产生磁场，变化的磁场产生电场，没有绝对不变的电场和磁场，因此电场和磁场是电磁场统一体中相互依存、相互制约的两个方面。它们遵从麦克斯韦方程组，随着时间的推移以电磁波的形式在空间传播。在狭义相对论中，电磁场的统一性表现得特别明显。 |
