  1. The " allowed " electric dipole ( el ) transitions will encounter strong competition from " forbidden " transitions, i. e. magnetic dipole ( ml ), electric quadruple ( e2 ) and other higher order transitions, the transitions rates for the forbidden decay scale with higher powers of z than those of el transitions, the effects of quantum electrodynamics ( qed ) also scale with higher power of z. accelerator - based beam - foil spectroscopy ( bfs ) is an important method for spectroscopic studies of highly ionized atoms

    在高離化態原子中,磁相互作用明顯增強, 「允許的」( e1 )躍遷將遭到來自磁偶( m1 ) 、電四極矩( e2 )和其它高次的「禁戒」躍遷的強烈競爭,禁戒躍遷幾率隨核荷數z增加而迅速增加,此外量子動力學效應也隨著z增加而增強。
  2. This paper puts emphasis on dynamic simulation based on switched reluctance drivers ' s ( srd ' s ) nonlinear model, and study of fuzzy control for srd. based on switched reluctance motor ' s linear, nonlinear model, the dynamic simulation model of srd ' s is built respectively. the phase current, phase torque, total torque and speed of srm in current chopping control ( ccc ) and angular position control ( apc ) are calculated respectively with this simulation
