domain boundary-
The main popular theoretical method adopted to study end - plate connection is finite element technique under monotonic loading at present. this paper applies nonlinear ( material, geometry and contact ) finite element method to analyze the behaviors of connections under cyclic load at fist time. contact elements are set between end plate and column flange, screw cap and neighborhood plane, bolt bar and hole
對于端板連接的理論分析，目前國內外的研究主要局限在單向加載有限元分析范疇，本文首次採用三維非線性（包括材料、幾何與狀態非線性）有限元對端板連接進行了循環加載分析，端板與柱翼緣間、螺栓頭（帽）與相鄰板件間、螺栓桿與孔壁間都設置了反映邊界狀態的接觸單元。Based on sndm technique, a method of local capacitance - voltage characteristic characterization of ferroelectric thin films was proposed. the effect of traps at oxide - semiconductor interface on metal - oxide - semiconductor structure capacitance - voltage curve was discussed, and the influence of coercive field to the capacitance - voltage characteristics of ferroelectric thin films was also discussed. the dynamic switching of ferroelectric domain in ca doping ( pb, la ) tio3 thin film was studied by sndm from the view of electricity
利用sndm ，從純電學的角度觀察了plct薄膜中的電疇動態反轉過程，由電疇橫向擴張的移動速度的降低，發現了晶界在電疇反轉過程中對疇壁移動的阻擋作用;根據sndm和pfm的在垂直方向上的不同信息敏感深度，得到plct薄膜中電疇反轉過程中電疇是楔形疇;用pfm觀察同一電疇在去掉外加反轉電場后電疇的極化弛豫現象，結果表明空間電荷是發生極化弛豫的主要原因。In addition, in the paper we also studied the annihilation of ordinary hard bubbles ( ohb ) by screening in order to measure accurately the critical in - plane field range
另外，為了更加準確地測定ohb疇壁中的vbl軟化的臨界面內場范圍，本文對經過篩選的ohb在h _ （ ip ）作用下其疇壁中vbl的消失規律給予了研究。The mbds in the compressed state and the mbds in the uncompressed state was compared in the experiment
在這個臨界面內場范圍內，疇壁中的vbl是逐漸丟失的。The influences of the pre - stress on the working characteristic of the actuator are analyzed by the measurement of displacement. a numerical current source with alternative working mode and current range is manufactured to provide program - set steady current for the drive coil
單晶材料消除了晶界對疇壁移動的影響，具有很好的低場下的位移輸出能力，這為微位移致動器的研製奠定了很好的基礎。Recently bulk tb - dy - fe single crystals have been obtained by magnetic levitation cold crucible without contamination in wuhan university of technology. these excellent single crystals, possessing a large displacement output under low magnetic field, build a foundation for the fabrication of the high precision micro - displacement actuators. the purpose of this research is to manufacture an advanced micro - displacement actuator with this high performance single crystal as the driving unit
常規的磁致伸縮型微位移致動器大多採用多晶或具有孿晶結構的磁致伸縮材料作為驅動單元，由於晶界和孿晶界對疇壁的移動具有阻礙作用，其低場下的位移輸出較小，調控精度受到很大影響。In the improved experiment the softening percentage of ohb was large at the critical in - plane field thus the critical in - plane field range related to the parameters of the samples was measured accurately in the paper. meanwhile facts have proved that ohb including less vbl is ohb which will lose vbl at the critical in - plane field
所以在本文中用比較準確的實驗方法測得了ohb疇壁中的vbl在面內場的作用下，存在一個與材料參量相關的臨界面內范圍h羅， h永] ，並且也證明了在臨界面內場h羅』時丟失vbl的ohb對應的是那些含vbl較少的ohbo分享友人
