由于实际晶体具有各向异性的物理、化学性能,研究单晶体性能的各向异性对于应用晶体的某些性能,以及了解多晶聚合体的特殊性能来说都是不可缺少的工作,这些工作都需要首先测定晶体的取向。因此测定晶体取向工作有着广泛的应用。确定晶体取向的方法虽然很多,但X射线衍射法定向是其中最普遍适用和最可靠的方法,故X射线分析法中的背射劳埃法和透射劳埃法早已被广泛地用来测定晶体取向。随着X射线分析仪器的不断发展和普及,使用衍射仪测定晶体取向的方法也发展起来了,在国内X射线衍射仪的使用已逐渐普及,国产衍射仪也已成批投产,但在实验室条件下使用衍射仪来测定单晶体取向的工作还未
Due to the anisotropic physical and chemical properties of actual crystals, it is indispensable to study the anisotropy of single crystal properties for some properties of crystal and for understanding the special properties of polycrystalline polymers, all of which require First determine the crystal orientation. Therefore, the determination of crystal orientation has a wide range of applications. Although there are many ways to determine the crystal orientation, the X-ray diffraction method is one of the most commonly used and most reliable methods, so the back-La Rau method and the transmission Rae method in X-ray analysis have long been widely used to determine the crystal orientation. With the continuous development and popularization of X-ray analytical instruments, the method of measuring the crystal orientation by means of a diffractometer has also developed. The use of X-ray diffractometers in China has been gradually popularized. Domestic diffractometers have also been put into mass production. However, The use of a diffractometer to determine the orientation of a single crystal under the conditions has not yet worked
