题目

“电子能量分析器”主要由处于真空中的电子偏转器和探测板组成。偏转器是由两个相互绝缘、半径分别为RA和RB的同心金属半球面A和B构成，A、B为电势值不等的等势面，电势分别为φA和φB，其过球心的截面如图所示。一束电荷量为e、质量为m的电子以不同的动能从偏转器左端M的正中间小孔垂直入射，进入偏转电场区域，最后到达偏转器右端的探测板N，其中动能为Ek0的电子沿等势面C做匀速圆周运动到达N板的正中间。忽略电场的边缘效应。下列说法中A连词成句将所给词语连成句子，标点已给出。1.well. is, feeling, he___________________________________________________________________________________________?2.is, your, smoking, health, for, bad____________________________________________________________________________________________.3.this, much, is, how, watch___________________________________________________________________________________________?4.he, me, helped, my, with, math____________________________________________________________________________________________.5.people, are, what, they, kind____________________________________________________________________________________________!
