剩余极化 meaning in Chinese
residual polarization
Examples
- It was found that the dropping rate in remnant polarization , pr ( n ) , of the samples would be accelerated when a high intensity or low frequency or square - wave of electric field was applied or at a lower temperature
实验结果表明，在高电场强度、低电场频率和在方波电场的作用下以及较低的温度下，铁电陶瓷材料剩余极化强度p _ r ( n )下降的速度变快。 - The hysteresis loops were detected , it is found that the remanent polarization and the conceive field of the ceramics deceased with the dope of ba2 + . in the composition range of mpb , the conceive field exhibit the lowest value
测试了样品的电滞回线，发现batio _ 3的掺入有效降低了nbt基陶瓷的剩余极化强度和矫顽场，在准同型相界组成点，矫顽场达到最小值。 - Based on recent published research , explanation about the experimental results was also given . remanent polarization and coercive field decreased with the increasing of la content . the crystal structure transformed from tetragonal to cubic when la concentration increased to 28mol %
在薄膜的铁电性质方面，随着掺镧含量的升高，剩余极化和矫顽场逐渐降低；当镧含量达到28mol时薄膜的结构从四方相转变到立方相。 - It was proposed that the reduction in pr ( n ) during the electric fatigue process was probably caused by the increase of a domain and anti - ferroelectric c * domain ( both leading to the increase in non - switching of c domain ) in combining with the experimental observation that the pr ( n ) values lowered with the rise of n . the equation which can be used to calculate the differences in non - switchable domain due to the increase of n was also given . variations of domain - switching with changes of n are discussed according to the in - situ xrd measurements
根据原位xrd实验观测结果，给出了c a畴的90畴变的近似估算公式，并结合宏观剩余极化强度随n增加而降低的实验观测，提出了疲劳过程中材料的剩余极化强度p _ r ( n )降低是由于a畴的增加和反铁电c ~ *畴增加导致不可翻转c畴增加共同造成的假设，并给出了不可翻转畴随n增加而变化的估算公式。 - Furthermore , in order to study the thermal fatigue of the films , the pzt films were heated by a laser beam , it was found that in the films the remnant polarization value decreased , the coercive voltage was basically constant , and the fatigue property of the films became more stabilized
接着用激光模拟热载荷作用在pzt薄膜上，发现薄膜的剩余极化变小，矫顽电压不变，铁电疲劳衰减率降低。分析这一现象产生的主要原因，是激光热作用影响铁电薄膜材料内部的极化分子和带电荷缺陷的运动所致。
