HOPG中存在两相,测量时应选择适当的测试条件,由于两相的存在,X射线衍射时,对石墨(002)峰K_α分辨率有一定的影响,并且显著地降低其衍射强度。
There are two phases in HOPG. The appropriate test conditions should be selected. Due to the existence of two phases, X-ray diffraction has certain influence on K_α resolution of graphite (002) peak and its diffraction intensity is significantly reduced.
