对微波布拉格衍射实验中产生衍射极大值晶面的讨论

Discussion on Crystal Surfaces Causing the Diffraction Maximums in Microwave Bragg Diffraction Experiments

通过理论推导出三厘米微波布拉格衍射实验中的模拟晶体只能产生一、二级衍射,而且只有十个晶面可以产生衍射极大值,并且采用微波分光仪可以进行测量。本文还对这些晶面的特点进行了分析讨论,得出只要通过三个有代表性的晶面(晶面族)作为该实验的研究对象,就能够全面研究微波布拉格衍射实验,以便于从事这方面教学与研究的有关专业人士参考。

In this paper, we derived that only the first and second order diffraction could be produced and the diffrac-tion maximums could be produced only in ten crystal surfaces for using the simulated crystal in the 3cm microwave Bragg diffraction experiment, these results also could be measured using microwave spectroscope. The characteristics of the crystal surfaces are analyzed and discussed;the results describe that the microwave Bragg diffraction experiment could be investigated thoroughly if we use the three typical crystal surfaces （or family of crystal surfaces） as the ob-ject of study. All of the obtained results in this paper could be used as a reference for those who are engaged in teach-ing and researching in this field.
