3 we use vsm , for annealing and do not annealing sample have gone on magnetic properties measure , combination origin software shows for the loop analysis of magnetic hysteresis : do not coercivity of annealing pellet membrane between38 . 898oe and 96 . 487oe , the coercivity of annealing sample between 30 . 327oeand91 . 591oe 3 、用vsm對退火和未退火樣品進行了磁性能測量,結合origin軟件對磁滯回線分析表明:未退火顆粒膜的矯頑力在38 . 898oe ~ % . 4870e之間,退火樣品的矯頑力在30 . 327oe ~引

In the models , the iron core nonlinearly of the traction transformer and the magnetic hysteresis effect without the b - h curve are considered . having tested by digital simulation , the winding parameter has not changed in the state of external fault or magnetizing inrush etc . but the winding parameter has obviously changed in state of inter fault or inter - turn fault . ( 3 ) the rules three phases converted to two phases of traction transformer in electric railways are developed in this paper ( 3 )利用牽引變壓器磁鏈平衡方程,建立了基于系統辨識理論的雙繞組單相接線牽引變壓器、阻抗匹配平衡牽引變壓器及scott (斯科特)接線牽引變壓器的“灰箱”模型,該模型考慮了牽引變壓器鐵芯非線性和磁滯效應,但又不直接反映在模型中,并且無需鐵芯的b - h曲線數據。

If the magnetic anisotropy of the magnetostrictive layer is much larger than that of the soft layer , the magnetic hysteresis and magnetostriction of the ecmm magnetized along the easy axis of the magnetostrictive layer are different from those of hard axis of the magnetostrictive layer 當磁致伸縮層磁各向異性與軟磁層磁各向異性相差較大時,沿磁致伸縮層的易軸方向或難軸方向磁化,多層膜的磁學及力學性質差別較大。

The simulation results of this study imply that magnetic hysteresis of mr dampers can really influence the semi - active control whereas neural network prediction can successfully compensate for the response time of mr dampers 研究表明,通過神經網絡預測能有效補償磁滯時間,使控制效果能接近無磁滯效應的控制效果。本文提出了考慮磁滯效應的修正bingham仿真模型。

The direction of the easy axis of the soft layer has little influence on the magnetic hysteresis and magnetostriction of the ecmm when the magnetic anisotropy of the magnetostrictive layer is much larger than that of the soft layer 雖然軟磁層的磁各向異性角對多層膜的磁學及力學性質幾乎沒有影響,但磁各向異性常數卻會顯著影響多層膜的性質。

The dissipative attenuation mechanism of the mn - zn ferrite that involved the natural resonance , the piezoelectric resonance and the magnetic hysteresis loss are also studied 本文還分析了錳鋅鐵氧體自然共振、磁滯損耗和疇壁共振等磁極化機制衰減吸收電磁波的各種機理。

In order to decrease control infection resulting from the magnetic hysteresis of mr dampers , neural network prediction is proposed in this paper 本文提出采用神經網絡預測的方法來減小磁滯效應對振動控制效果的不利影響,得出了一些有價值的結論。

Taking into account of magnetic hysteresis of mr dampers , revised bingham model for mr dampers is proposed in this dissertation 通過該模型得到樣本數據,建立了能夠模擬mr阻尼器逆向工作特性的逆模式神經網絡模型。

Hexa - ferrites are characteristic of ferromagnetism and conductance , so that they can produce magnetic hysteresis loss and electricity loss 它既能產生磁滯損耗又能產生電致損耗,因而是一種優良的微波吸收材料。

In the end , influence of grain size on the magnetic properties of the samples in the room temperature is studied by the magnetic hysteresis loop 最后,還研究了幾種納米晶微粒的晶粒線度對其磁學性質的影響。

Magnetic hysteresis is the intrinsic characteristic of mr dampers , which will have more serious effect on the performance of mr dampers 本文對mr阻尼器的固有特性磁滯效應對控制效果的影響進行了研究。

When the resistance force is large , magnetic hysteresis will have more serious effect on the performance of mr dampers 分析表明,磁滯效應會給控制帶來不利影響,并且隨著磁滯時間的增加而趨于嚴重。
