So we conclude that observed electron energy spectrum about 10 mev in large flare may be produced by the acceleration of synchrotron radiation 因此我们认为太阳耀斑中10mev左右的能谱是由同步加速辐射加速日冕快电子产生的。
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 选取适当的参数,我们得到的能谱与linetal . ( 1982 )得到的太阳耀斑中10mev左右的电子能谱一致。
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 本文第一章对粒子加速理论以及目前各种加速理论在太阳日冕中的应用作了介绍;第二章通过理论计算得到同步加速辐射谱以及电子能谱;第三章选取太阳日冕中典型参数,对同步加速辐射加速日冕快电子作了简单讨论。
