摘要:

Hamilton原理是描述孤立保守系统的变分原理,其Lagrange函数是系统的动能与势能之差。通过费曼路径积分,我们可以得到厄米量子理论,即,标准薛定谔方程本文给出了广义Hamilton原理,它能描述开放系统(质量或能量交换系统)和非保守力系统或耗散系统。在此基础上,我们给出了广义拉格朗日函数,它与动能、势能和非保守力所做的功有关。利用Feynman路径积分,给出了非保守力系统的非厄米量子理论。另外,我们给出了粒子与外界进行热交换的广义哈密顿函数,即动能、势能和热能之和,并进一步给出了量子热力学方程。

英文摘要:

The Hamilton principle is a variation principle describing the isolated and conservative systems, its Lagrange function is the difference between kinetic energy and potential energy. By Feynman path integration, we can obtain the Hermitian quantum theory, i.e., the standard Schrodinger equation. In this paper, we have given the generalized Hamilton principle, which can describe the open system (mass or energy exchange systems) and nonconservative force systems or dissipative systems. On this basis, we have given the generalized Lagrange function, it has to do with the kinetic energy, potential energy and the work of nonconservative forces to do. With the Feynman path integration, we have given the non-Hermitian quantum theory of the nonconservative force systems. Otherwise, we have given the generalized Hamiltonian function for the particle exchanging heat with the outside world, which is the sum of kinetic energy, potential energy and thermal energy, and further given the equation of quantum thermodynamics.
