The camera length of electron diffraction in transmisson electron microscopy is one of the main technical parameters in designing electron microscope and the electron diffraction analysis to microcrystal sample. According to Bragg law, the formula of calculating TEM electron diffraction camera length is derived from the research on the ray path of electron diffraction images in TEM and the comparison on electron diffraction with ordinary electronic diffractometer. The difference of physical significance of electron diffraction camera length between TEM and ordinary electronic diffractometer is discussed.

透射式电子显微镜(Transmisson Electron Microcopy， TEM)中的电子衍射相机长度，是电子显微镜设计和对微晶体样品进行电子衍射分析的主要技术参数之一依据布拉格定律，经对TEM中电子衍射成像光路的探讨与研究，并通过TEM与普通电子衍射仪的电子衍射的对比分析，导出了TEM电子衍射相机长度的精确计算公式，阐述了TEM和普通电子衍射仪的电子衍射相机长度所表征的物理意义的区别。

One electron volt is defined as the kinetic energy gained by an electron when it is accelerated by a potential difference of one volt.

我们把一个电子被一伏特的电位差加速后所得到的动能定义为一电子伏特。

Variation laws of electron movement with emergence angle and microwave electromagnetic parameters are also derived. The emergence angle of electron has significant effect on the movement of electron, and there is an emergence angle in which the electron has the maximum trajectory length and impact energy, Impact energy will increase and return time will reduce as increasing the amplitude of electric field, and both parameter would oscillate with the phase of electric field, which can essentially explain that multipactoring electron number oscillates in twice the frequency with the increase of microwave frequency, electron trajectory will change from parabolic-like movement to complex oscillation.

研究发现：电子出射角度对其运动状态有显著影响，电子存在运动轨迹最大的某一出射角度，该角度下电子拥有最大的撞击能量；微波电场幅值的增加将使电子撞击能量增加，返回时间减小，微波电场相位的变化使电子的撞击能量和返回时间呈周期振荡，这从本质上解释了电子数量在二次电子倍增过程中以微波频率两倍周期振荡的原因；随着微波频率的增加电子将由简单的类抛物线运动转变为复杂的振荡运动。

electron volt：电子伏特

假如这些交换低于一个电子伏特(electron volt)的话,例如房间内的空气分子之间发生碰撞,那么,原子和分子即可被视作基本粒子(elementary particle). 换言之,它们具有"有条件的基本性",因为它们保持其原有身份,在任何这类低能量交换的碰撞或其它过程中保持不变.
