本研究题目是针对国产Y一2衍射仪记录部分比较落后的手工数据测量处理方式进行计算机联机数据处理改造。这项研究可大大减轻国产衍射仪使用操作人员的工作量,提高衍射仪的利用率和分析速度,对于国产衍射仪的改造有一定的实用价值。一、衍射峰位判定方法从理论上讲,每一个衍射曲线都应是一种高斯形分布曲线,但实际的衍射曲线往往与之相差甚大,一方面是因为实际的衍射曲线是由一些衍射曲线的不连续的数据点连成的。再加上显示误差,其峰位和峰形与实际情况会有一定的误差,另外,测量系统的噪声、非线性和重迭引起的峰的重合,都会使
The subject of this research is to conduct computer on-line data processing and reformation based on the manual data measurement and processing methods of domestic Y-2 diffractometer. This study can greatly reduce the workload of the domestic use of diffractometer operators to improve the utilization of diffraction and analysis speed, for the transformation of domestic diffractometer has some practical value. First, determine the diffraction peak position In theory, each diffraction curve should be a Gaussian distribution curve, but the actual diffraction curve is often very different, on the one hand because the actual diffraction curve is composed of some diffraction curves Discontinuous data points into the. Coupled with the display error, the peak position and peak shape and the actual situation will have some error, in addition, the measurement system noise, non-linearity and overlap caused by overlap, will make
