前言X 射线多晶分析在化学研究工作中有很广泛的用途。常用的仪器是 Debye 粉末照相机和 X 射线衍射仪。还有一种 X 射线单色聚焦粉末照相机。它从卅年代末问世以来,经过逐步改进,已经成为一种有效的实验工具。目前正朝着高、低温领域和高精密度的方向发展。由于 X 射线的单色化和聚焦作用,仪器的分辨率大大地提高了。在鉴定复杂的物相组成时效果较好。多年来,我们曾使用 Guinier 单色聚焦粉末照相机进行常规物相分析,以及某些特殊试样的鉴定。例如金属有机化合物、天然有机化合物;r-Fe_2O_3中的少
Foreword X-ray polycrystalline analysis has a wide range of uses in chemical research. Commonly used instruments are Debye powder cameras and X-ray diffractometers. There is also an X-ray monochromatic focus powder camera. Since its introduction in the late 1930s, it has become an effective experimental tool after gradual improvement. Currently moving in the high and low temperature areas and high-precision direction. Due to the monochromatization and focusing of X-rays, the resolution of the instrument is greatly increased. In the identification of complex phase composition better. For many years we have used Guinier monochromatic focusing powder cameras for routine phase analysis and the identification of certain special samples. For example, metal organic compounds, natural organic compounds; less r-Fe_2O_3
