中文拼音 [cíǒujíjǔ]
磁偶極矩
英文
magnetic dipole moment-
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」電偶極（ e1 ）躍遷將遭到來自磁偶極（ m1 ） 、電四極矩（ e2 ）和其它高次的「禁戒」躍遷的強烈競爭，禁戒躍遷幾率隨核電荷數z增加而迅速增加，此外量子電動力學效應也隨著z增加而增強。In this application, the lorentz force generated by the interaction between the current in the wire and the geomagnetic field produces an electro - dynamic drag leading to a fast orbital decay. in this paper, we make an intensive study of the process of de - orbiting using electro - dynamic tether system. the concrete work includes : firstly, i have studied the basic principle of how to generate the electro - dynamic drag, modeled via accuracy geomagnetism, made a concrete analysis of the de - orbiting duration, the magnitude and direction of electro - dynamic drag under the action of the dipole and accurate geomagnetic models, set up a counterbalance between electro - dynamic torque and gravity gradient torque, emulate the de - orbiting process of spacecraft, and compared the change of six orbital factors and the de - orbiting duration under the action of the dipole and accurate geomagnetic models
