通过组织化学、原子显微镜检查法、扫描电子显微镜术和透射电子显微术来研究基质的变化。

New methods of measurements of specimen thickness and non-elastically scattering mean free path are proposed based on the electron holograph combining with electron dynamic diffraction.

而且，在电子全息照片和电子动力衍射相结合的基础上我们提出了一种测量电镜样品厚度和样品非弹性散射自由程的新方法。

Maintain deflector if the size of the same voltage, the voltage change is accelerating, we can see a very accelerated voltage reduce, electron beam deflection angle instead of increasing, it is because of low accelerating voltage, the electron velocity smaller horizontal direction, electronic deflection plates in the field of the role of the extended time, the angle of deflection increases .

如果保持偏转板的电压大小不变，改变加速极的电压，可以看到加速极的电压减小，则电子束偏转的角度反而增大，这是因为加速极电压低，则电子的水平方向速度变小，电子在偏转板中受电场力作用的时间加长，所以偏转的角度增大。
