So we conclude that observed electron energy spectrum about 10 mev in large flare may be produced by the acceleration of synchrotron radiation 因此我們認(rèn)為太陽(yáng)耀斑中10mev左右的能譜是由同步加速輻射加速日冕快電子產(chǎn)生的。
Using fokker - planck equation , the acceleration of fast electrons by the spectrum will produce the power - law electron energy spectrum . by selecting suitable parameter we get the same spectrum as that lin et al . obtained in 1982 選取適當(dāng)?shù)膮?shù),我們得到的能譜與linetal . ( 1982 )得到的太陽(yáng)耀斑中10mev左右的電子能譜一致。
In chapter one , we make a review of particle acceleration theory and the use in solar corona . in chapter two , first we get the spectrum of synchrotron radiation then obtain the electron energy spectrum . in last chapter , we select the typical solar active region parameter to compare our result to the observation and discuss the acceleration mechanism 本文第一章對(duì)粒子加速理論以及目前各種加速理論在太陽(yáng)日冕中的應(yīng)用作了介紹;第二章通過(guò)理論計(jì)算得到同步加速輻射譜以及電子能譜;第三章選取太陽(yáng)日冕中典型參數(shù),對(duì)同步加速輻射加速日冕快電子作了簡(jiǎn)單討論。
