《相对论电子学》教学难点CAI

CAI for Teaching Difficulties of "the Relativistic Electronics

针对《相对论电子学》教学中所涉及到的主要难点问题，如：自由电子激光的物理机制；谱波自由电子激光的物理机制；虚阴极振荡器的物理机制；任意倾角斜旋转轴准光腔回旋管（ＡＱＣＯＲＡＡ）的物理机；电子回旋脉塞的饱和机理－相位捕获等；以非线性理论为基础，模拟电子与波互作用从线性调制到非线性饱和的演化过程，以图形方式实时动态显示了电子的群聚和换能，形成了教学软件ＲＥ—ＣＡＩ。

For the major difficulties in teaching 'the Relativistic Electronics', such as free electron laser's physic mechanism, harmonic free electron laser's physic mechanism, gyrotron with quasi-optical cavity of any configuration's physic mechanism, saturation mechanism-phase capture and so on, the evolution of the niteraction between electrons and wave from linear modulating to nonlinear saturation is on the basis of noalinear theory. The energy interchange and bunching of electrons in real-time and animation are displayed,and a teaching program 'RE-CA' is also formed in this paper.
