畴界运动 meaning in English

domain boundary motion

Accordingly , a new framework , which provides a common scheme for the numerical simulation on the macroscopic behavior of ferroelectrics though multi - scale analysis on the coupled thermo - electrics - mechanical behavior of multiphase in heterogeneous material , is induced to construct the effective constitutive equation of multiphase . in chapter four , based on the law of domain nucleation and domain wall motion of 1800 domain switching , a new scheme of domain switching and numerical simulation approach is put forward on the foundation of thermodynamics . driving traction , nucleation criterion , velocity of domain wall motion , kinetic relation and rate of domain switching in a single grain are given
第四章以铁电体1800畴变的过程中形核规律和畴界运动规律的实验观察结果为基础，根据热力学理论建立铁电体畴变的理论框架和数值模拟方法；给出了单畴内畴变驱动力、新畴形核准则、畴界运动速度公式、畴变动力学的表达式，单晶的畴变速率公式；用细观力学的观点给出了对多晶铁电体多场耦合的有效性质进行包含畴变速率影响的多尺度分析方法。
