求翻译:HRTEM显示晶格条纹是因为TEM通过电子打在样品上是微小的一个点,可能正好打在某个晶粒上。XRD检测反映的是面积相对大的某个区域,由于其整体呈现非晶态,所以没有明显的衍射峰。是什么意思? 待解决

Display lattice streaks HRTEM because TEM through electronic in the sample is the minor a point, may be exactly two hits in a die. The test was a reflection of XRD are relatively large an area, due to its overall render non-crystal. So there is no obvious Diffraction.

HRTEM demonstrated the crystal lattice stripe is because TEM hits through the electron in the sample is a small spot, possibly happen to hits on some crystal grain.The XRD examination reflection is the area relatively big some region, because its whole presents the amorphous state, therefore does no

HRTEM show lattice fringes because TEM electronically on the sample are tiny points, you may hit on a grain. XRD measurement reflects the area of a region, due to its amorphous, so no clear diffraction peaks.
