By finding that the projection operators of the basic quantum mechanical representations can be written as operator delta functions, we derive the explicit forms of quantum-mechanical fundamental representations in Fock space by directly carrying out the integrals within the normally ordered product of operators.

简单推导量子力学基本表示形式的显式形式

通过发现基本量子力学表示的投影算子可以写为算子德尔塔函数，我们通过直接在算子的正常有序积内进行积分来推导福克空间中量子力学基本表示的显式形式。
