利用经典极限的约束哈密顿描述导出了量子-经典混合系统的相容动力学方程。从哈密顿体系中的复合量子系统出发，对其中一个子系统施加经典行为的条件，导出相应的混合动力学方程。所提出的形式主义表明，混合系统的属性，不用尽的量子和经典系统。
Constrained Hamiltonian description of the classical limit is utilized in order to derive consistent dynamical equations for hybrid quantum-classical systems. Starting with a compound quantum system in the Hamiltonian formulation conditions for classical behavior are imposed on one of its subsystems and the corresponding hybrid dynamical equations are derived. The presented formalism suggests that the hybrid systems have properties that are not exhausted by those of quantum and classical systems.
