landau theory meaning in Chinese
朗道理论
Examples
- Finally ， we also get multi - loop hysteresis by monte carlo method which matches the expectation of landau theory
最后，本文还成功使用蒙特卡罗方法成功地划出了多重回线，与朗道理论预言的一致。 - When temperature is very close to the temperature of phase transition , critical phenomena appear in the system . fluctuation of order parameters leads to the failure of landau theory of phase transition
但是，在充分接近相变点时，系统出现临界现象，序参量有显著的涨落，这导致landau理论的失效。 - Cumulative integral is used to research the phenomenon . comparing this conclusion with that of applicable scope of landau theory , we discuss the relation between them and the essence of coefficient k and correlation length
文中用累积积分进行研究，联系landau理论在临界区的适用性，探讨ginzburg梯度项系数k与关联长度的实质。 - In the framework of the transverse ising model ( tim ) , landau phase transition theory and the electrostatic field theory , we study the physical properties of the ferroelectric thin film , bilayer , sandwich structure , multilayer with a non - polarization slab and a two - dimension polar lattice model with polar defects . the main work and results are as follows : first , the long - range interaction in ferroelectric material is sometimes neglected in the previous studies . we introduce the long - range interaction in the framework of the tim and the landau theory
本文在横场伊辛模型、朗道相变理论以及静电场等理论的框架内，对铁电薄膜、铁电双层膜、铁电三明治结构以及含有杂质层的铁电多层膜和含有偶极缺陷的二维偶极点阵系统等多层铁电系统的相变、热电、介电、电滞行为等物理性质进行了深入研究。 - Once landau theory of phase transition was used to deal with ferroelectrics phase transition . it introduces symmetry breaking into phase transition theory and associates it with order parameter to find the necessary condition of occurrence of phase transition . the theory has settled plenty of problems
对于铁电体，以前采用landau理论处理连续相变，这一理论引入对称破缺，并将它与序参量的变化联系起来，找到发生连续相变的必要条件，这成功地解决了一些问题。
