摘　　要：针对学生在进行X射线粉未衍射实验中普遍存在的对实验参数选择的盲目性及对导致实验数据或图谱偏差的因素认识不清等问题,做了一些实验与探讨,以引导学生重视实验参数的设定,按具体的实验要求,正确地选择实验条件。Studies were made on the proper experimental parameter settings when performing X-ray powder diffraction. The examples of effects of the'parameter settingion the quality of the data and diffraction profiles were given so as to let undergraduate students learn how to choose experimental conditions according to the individual requirement.
