波在传播途中,遇到障碍物要发生衍射,人们将它用于理化分析.本文主要介绍对压电与声光专业理化分析有用的电子衍射、X射线衍射和中子衍射的原理和方法、各种先进的衍射仪器及其性能以及它们在理化分析中的应用.文中重点介绍了电子显微镜和X射线衍射仪以及日本理学公司的单晶体X射线自动分析装置和结构分析流程.还将反射式高能电子衍射与低能电子衍射、中子衍射与X射线衍射进行了比较.
Wave in the middle of the road, encountered obstacles to diffraction, people will use it for physical and chemical analysis.This paper mainly introduces the principle and method of electron diffraction, X-ray diffraction and neutron diffraction useful for piezoelectric and acousto-optic professional physicochemical analysis, A variety of advanced diffraction instruments and their performance and their physical and chemical analysis of the application.In this paper, the focus of the electron microscope and X-ray diffraction instrument and Japan’s science company single-crystal X-ray automatic analysis device and structure analysis process will also be reflective high energy Electron diffraction and low energy electron diffraction, neutron diffraction and X-ray diffraction were compared.
