_ incremental form of evolution law of domain switching is developed by taking the volume fraction of domains as key intrinsic factors. the main factors that have great influence on domain switching are material parameters, domain wall motion, domain volume fraction and the interaction energy between inclusion and matrix. inclusion and its neighbors could be addressed in the description as well
? ?建立了以電疇翻轉時的體積分數增量為中心的，基於鐵電疇壁運動特性的剩餘應變及電位移的增量形式的演化方程，在其中包含有材料參數、疇壁運動、電疇形式、電疇體積分數及基體與夾雜、夾雜與夾雜等相互間能量作用等影響因素。 -
The volume of the output filter can be reduced greatly used in cascade inverter with carrier - phase - shifted spwm technology which has a high equivalent switching frequency and a good output sine wave. it is the base of the high power density of asi
載波移相正弦脈寬調制技術有獨特的消諧波優勢，其等效開關頻率高，輸出波形正弦度好，可以大幅減小濾波器體積，為實現系統的高功率密度奠定基礎。 -
_ the phenomenon of saturation or " lock up " when all of the grains have transformed, is described in a rattier simple form through domain volume fractions by the proposed model, in which domain switching in ferro - electrics is analogous to that of dislocation movement on crystal slip planes in metals
? ?依據晶體塑性理論，將鐵電材料中的電疇翻轉類比于晶體位錯滑移面上的滑移系，定義鐵電材料中相應的電疇反轉系；採用電疇的體積分數表述電疇翻轉的變化量，得到了電疇翻轉的飽和特性的簡單描述。 -
If other end offices have rapid increase in the suburban traffic volume, this suggestion can be used with some adjustment, and the new added switching system also be transferred into city network based on incoming and outgoing calls
在以後的運行中，如果其他端局市郊話務量增長較快時，也照此方案進行調整，並且以後新開的交換系統也需按來去話匯接方式入網。 -
This paper discussed the theory of switching - node preset optimal spwm detailedly, and got the solution of 9 waves, 13 waves, and 17 waves switching - node preset optimum spwm control strategy. furthermore, by means of raising the switching frequency, the quality of output voltage can be promoted, the resonate frequency of output filter can also be raised, which made the inverter smaller volume and lighter weight and more efficient
本文首先對開關點預置最優spwm控制策略進行了深入研究，分別求解出了九塊波、十三塊波、十七塊波等情況下的最優spwm控制的開關角，並討論了在提高開關頻率之後進一步優化輸出濾波器設計，在保障系統效率的前提下，提高輸出波形質量和減小濾波器的體積重量。 -
