Also known as charge (theoretical physics), physical charge (general), generalized charge, charge (physics), abstract charge, charge quantum number, Noether charge
generalization of electric charge (EM) adding color charge (QCD), mass-energy (gravitation), etc.; sometimes considered same as its charge quantum number

物理學中,荷(英語:Charge)可指不同的量值,例如電磁學中的電荷,或是量子色動力學中的色荷。荷对应于对称群中时不变的生成集,具体来说,对应于与哈密顿算符可交换的生成子。通常使用字母Q来表示荷,因此荷的不变性对应于湮灭交换子,其中H为哈密顿算符。因此,荷與守恒的量子数有關;这些量子数即为生成子Q的本征值q。
