We shall show that continuous symmetery transformation in quantum field theory, which leave the equation of motion invariant, will generate conservation laws without use Noether theorem of Lagrangian formalism. 本文从对称变换保持系统的动力学方程(以及对易关系)不变出发,推导出量子场论中的连续对称变换所产生的守恒律,而不借助于拉格朗日体制的Noether定理。
Potential Energy Function of the Molecule with C_ ( 2v) Symmetery C(2V)对称的分子势能函数
According to voltage reactive conditioning and burden power, multiple connection the capacitor lift a hand to of the correlation of, it carries out reactive flows reasonable symmetery. 根据电压无功调节与负荷功率、并联电容器出力之间的相互关系,实现无功潮流合理平衡。
