Maxwell's Equations

麦克斯韦方程

Maxwell's equations represent one of the most elegant and concise ways to state the fundamentals of electricity and magnetism. From them one can develop most of the working relationships in the field. Because of their concise statement, they embody a high level of mathematical sophistication and are therefore not generally introduced in an introductory treatment of the subject, except perhaps as summary relationships.

麦克斯韦方程组是表述电磁学基本原理最优雅且简洁的方式之一。从这些方程可以推导出该领域大多数实用关系。由于其简洁的表述,它们体现了高度的数学 sophistication,因此通常不被包含在电磁学入门性论述中,除非作为总结性关系。

These basic equations of electricity and magnetism can be used as a starting point for advanced courses, but are usually first encountered as unifying equations after the study of electrical and magnetic phenomena.

这些电磁学的基本方程可以作为高级课程的起点,但通常是在学习电和磁现象之后,才首次作为统一的方程被遇到。
