The methods above have been simulated using emtp and matlab, and the simulation results indicate that, ( 1 ) in the fault location method based on wavelet reconstruction, the influences of reflected waves from tee joints or resistance discontinuities except the fault point can be eliminated when the current difference between faulty phase and sound phase is used in fault location
本文利用emtp和matlab程序對上述方法進行了數值模擬，結果表明： （ 1 ）在本文所提出的基於小波重構的電纜故障測距方法中，利用健全相和故障相的電流差信號進行故障定位，能消除故障點之外其他阻抗不匹配點的反射波的影響。As a result, this paper gives a corresponding harmonic prevent me asure. finally, according to the asymmetrical characteristics of electrical traction loads, this paper studies the negative sequence currents under different loads and makes a piece of advice for reducing the negative sequence currents produced
最後，還根據電力牽引負荷三相不對稱的特點，分析了阻抗匹配平衡變壓器在不同負荷條件下的負序電流，對如何減小電力牽引負荷的負序電流提出了一點建議。By a large amount of calculations, the influence of the structure dimensions and the dielectric parameters on dispersion characteristic and coupling impedance of this kind of slow - wave structure is obtained. then, the linear beam - wave interaction theories of the arbitrarily - shaped helical groove waveguide and the dielectric into the arbitrarily - shaped helical groove waveguide are deduced. by the numerical calculations, the relationship is got between the small signal gain, bandwidth, electromagnetic " hot " velocity and the electronic beam, the structural parameters
通過數值計算，獲得了此類慢波結構的色散特性和耦合阻抗隨結構幾何尺寸和介質參數的變化規律;在此基礎上，建立了任意槽形螺旋槽及中心加介質棒的任意槽形螺旋槽行波管的注-波互作用線性理論，並編製程序，計算了管子的小信號增益、帶寬、電磁慢波的「熱」相速與電子注參數、結構參數之間的關系，獲得了增加帶寬或增益的途徑。By utilizing the knowledge of digital circuit and simulation circuit, the system designs the pretreatment dealing circuit of the myoelectrical signal, which has the feature of big input impedance well suppress of public module and high gains. then the signal is gathered with " zhentong " data gathering after dealing with, and the software of signal processing is explored before the myoelectric signal is analyzed. after picking up eigenvalue, it is proved that the result is unanimous basically with the data of the relevant materials ; the other is to control artificial hand by the eigenvalue of the myoelectric signa l and at last the system gets very good control results
即利用數字電路和模擬電路等相關知識，設計了具有輸入阻抗大、共模抑制好、增益高等特點的肌電信號前置處理電路，利用「振通」數據採集儀對處理后的信號進行採集，並利用快速傅立葉變換的相關知識編寫了信號處理程序，對肌電信號進行了波形分析、幅值譜分析和功率譜分析，提取了信號特徵值，與相關資料的數據相比，基本一致；二是利用肌電信號的特徵值對肌電假手進行控制。分享友人
