landau theory 中文意思是什麼
landau theory
解釋
朗道理論-
Finally ， we also get multi - loop hysteresis by monte carlo method which matches the expectation of landau theory
最後，本文還成功使用蒙特卡羅方法成功地劃出了多重回線，與朗道理論預言的一致。 -
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，在充分接近相變點時，系統出現臨界現象，序參量有顯著的漲落，這導致landau理論的失效。 -
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
文中用累積積分進行研究，聯系landau理論在臨界區的適用性，探討ginzburg梯度項系數k與關聯長度的實質。 -
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
本文在橫場伊辛模型、朗道相變理論以及靜電場等理論的框架內，對鐵電薄膜、鐵電雙層膜、鐵電三明治結構以及含有雜質層的鐵電多層膜和含有偶極缺陷的二維偶極點陣系統等多層鐵電系統的相變、熱電、介電、電滯行為等物理性質進行了深入研究。 -
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
對于鐵電體，以前採用landau理論處理連續相變，這一理論引入對稱破缺，並將它與序參量的變化聯系起來，找到發生連續相變的必要條件，這成功地解決了一些問題。
