提出马氏体相变的非平衡量子统计理论,考虑到了马氏体相变的特殊性:本身为远离热平衡相变,但马氏体相处热力学支。这需要合理应用激光物理、耗散结构理论、经典统计和量子体系的哈密顿动力学。本文建立一个简单的统计模型以说明电子-晶格强耦合体系的跃迁特征。非平衡统计部分由Master方程在声子表象中研究。导出的熵变式表明integral from n=path dS<0过程在形成粒子数反转中起关键作用,并示出在何种条件下,晶格原子跃迁特征由各个原子散乱跳越变为相干声子驱动的所有原子的协同跃迁。分折了马氏体相变的“声Laser”工作机理和激光阈的差别,并指出二者的基本原理一致。
The unbalanced quantum statistical theory of martensitic transformation is proposed, which takes into account the particularity of martensitic transformation: itself is away from the thermal equilibrium phase transformation, but the martensite coexists with the thermodynamic branch. This requires the rational application of laser physics, dissipative structure theory, classical statistics and Hamiltonian dynamics of quantum systems. In this paper, we establish a simple statistical model to illustrate the transition characteristics of the electron-lattice strongly coupled system. The unbalanced statistics is partly studied by the Master equation in the phonon appearance. The derived entropy variant shows that the integral from n = path dS <0 plays a key role in the inversion of the formation of particles and shows under what conditions the transition of lattice atomic transitions from interspersed to discrete Collaborative transition of all atoms driven by a sub. Distinctive martensitic transformation of the “acoustic Laser” working mechanism and the difference between the laser threshold, and pointed out that the basic principles of the two consistent.
