摘要
本文研究连续媒质体系振动波场的性质,由经典波动方程的解过渡到量子化场,推导出了以产生和消天算符表示的量子化场哈密顿量,再进一步讨论其物理意义.所得结果为理解有关物理问题提供了一个基础.
In this paper,the properties of the wave field of a contionous material system from vibration are studied,considering thetion of the classical wave equation and its quantization.Then the Hamiltonian represented by creation and annihilation operatederived carefully and its physical meanings are iscussed,the results obtained provide a basis to understand the related problerphysics.
