X射线跟我们眼睛感觉到的可见光一样都是电磁波,但X射线的波长要小得多.我们常说的X射线的波长在0.1埃至10埃之间。而物质的原子或分子的空间排列也在这个尺度范围中.每个原子或分子是一个对波的散射体,根据波的衍射原理,如果物质的原子或分子的空间排列有一定的周期性,则X射线会在物质中产生衍射现象.如果我们收集衍射信号并加予分析,就可以揭示晶体内的原子和分子的空间排列状况.X射线衍射技术正是这样一门科学技术,它在物理学、材料科学、化学、生物学等众多的领域中有着广泛的应用.
X-rays are the same electromagnetic waves as the visible light of our eyes, but the X-ray wavelength is much smaller, and we often say that the X-ray wavelength is between 0.1 angstroms and 10 angstroms. The atomic or molecular arrangement of matter is also within the scope of this scale.Each atom or molecule is a scatterer of waves, according to the wave diffraction principle, if the atoms or molecules of the material are arranged in a certain period of space, Then the X-ray will produce diffraction phenomenon in the material.If we collect the diffraction signal and add the analysis, we can reveal the spatial arrangement of the atoms and molecules in the crystal.X-ray diffraction technology is such a science and technology, it is in physics Science, materials science, chemistry, biology and many other fields have a wide range of applications.
