  1. Furthermore, this dissertation also gives a comprehensive analysis and comparison to the torque ripple factor, torque - current ratio and other aspects for pseudo - sinusoidal emf bldcm drived by 120 conduction mode, 180 conduction mode and self - synchronous svpwm mode respectively. the simulation and the experimental results indicate that self - synchronous svpwm method is more effective for minimizing the torque ripple without any expense of the torque - current ratio when the crest width of the back - emf waveform is less than 107 electrical angles

  3. Imev and the data in which the energy respectively is 166mev 139mev, 104mev, 90mev. on the basis of two wave functions and two optical potentials above mentioned, we have investigated a serie s of knockout reactions : through the comparing of two wave functions and two optical potentials, we find that two a cluster relative vave functions which contribute to the energy sharing results of the reaction sections are very well, especially for the ; that the received spectroscopic factors used vfm ( r ) are better than that used ; that the former not only suits to the elastic scatterings but also to the knockout reactions ; that the a cluster of knockout reactions are its local behaviors of surface. and we further testify that the distorted influences are not neglected if the incidence energies are not very high, but can be used the plane wave impulse approximate method and neglect the effects of the distorted influences if the incident energies are high enough

    在利用上述的兩種束縛態波函數和兩種光學勢的基礎上，我們研究了一系列的敲出反應：通過對比兩種束縛態波函數和光學勢，我們得到的結論是：兩種束縛態波函數和光學勢對反應截面的能量分配譜的貢獻都比較好，但尤以波函數_ （ li ） （ r ）為佳；光學勢v _ （ clu ） + （ r ）得到的光譜因子比用woods - saxon勢v _ （ ws ） （ r ）的結果要好，它不僅能適用於彈性散射，且對敲出反應也能得出比較好的結果；集團的敲出反應是集團表面局域性的表現：在中低能的入射條件下，扭曲效應不能忽略，但入射能量較高時，扭曲效應影響較小，可以用平面波沖量近似的方法。
