Then two possible cases of electron distribution are discussed 然后就结链中可能存在的两种电子数分布情形进行了讨论。
In the optimized structure , the electron distribution at the exit hole of the chunnel is more uniform and the electron beam is rather slim 在该结构中,电子在通道出口处的分布更加均匀,电子束的束径较小。
From this expression we know that , once the electron distribution is given , we can get the exact potential distribution in all islands 由这个表达式我们知道,只要给定了结链中的电子数分布,就可以准确得到各岛的电势分布。
When primary electrons hit the surface of the chunnel , secondary electrons are generated , which make the electron distribution at the exit hole of the chunnel more uniform 当初始电子碰撞绝缘壁时,会产生二次电子,而二次电子能改善电子在通道出口处的电子能量分布的均匀性。
The effect of the form of electron distribution function on electron temperature was also discussed in the first part . in the second part , starting from kinetic equations , we discussed stimulated raman scattering ( srs ) by including both landau damping ( ld ) and the collisional damping ( cd ) 第二部分从含有限碰撞效应的vlasov - maxwell方程组出发,首先推得含碰撞阻尼和landau阻尼的描述受激raman散射的耦合方程组,然后讨论受激raman散射的线性增长率。
