The canonical formalism of a Lorentz gauge theory of gravitation 一种Lorentz引力规范理论的正则形式
We introduce generally vector potential A and scalar potential φ to discuss the radiation of the electromagnetic wave and use the Coulomb gauge and Lorentz gauge to simplify the equations of electromagnetic field and its solutions. 讨论电磁波的辐射时,通常引入矢势■和标势φ。并采用库仑规范和洛仑兹规范使电磁场方程和求解简单化。
By means of the commutation relation between the γ-matriees and the generators of the Lorentz group, we obtain the expression of gauge potential for the related "isotopic space". 借助γ-矩阵和洛仑兹群生成元的对易关系,得到相应的同位旋空间的规范势的表达式。
By means of it and together with the Lorentz gauge, the interface conditions between the conductor and non-conductive region can be transformed into boundary conditions for the field in non-conductive region. 应用这个矩阵及罗仑兹规范,在T-Ω描述中涡流区与非导电区的分界面条件可化为非导电区的边界条件,从而可以单独求解。
A modified PEEC model was introduced, in which the integral definition of vector magnetic potential and the Lorentz gauge are used to expand the integral equation to derive the PEEC. 提出了一种改进的部分元等效电路模型,它以矢量磁位的积分表达式和洛仑兹规范代替了矢量磁位和标量电位的积分表达式,对积分方程进行展开。
