水泥熟料矿物组成的定量分析方法主要有经典鲍格计算法、显微镜统计法和X射线衍射法,各自优缺点Aldridge~([1])、洪汉烈~([2])、李家驹~[3])已有介绍。全谱拟合Rietveld法利用整个衍射空间的散射信息,用多个含有不同物理含义的模型对试验数据衍射谱进行拟合分析。拟合过程采用非线性最小二乘拟合算法不断调节模型中参数值,最终使试验数据与模型计算值间达到最佳吻合。Rietveld法目前已被认为是一
The methods for the quantitative analysis of mineral composition of cement clinker mainly include classical Burg calculation method, microscopic statistics method and X-ray diffraction method. Their respective advantages and disadvantages are Aldridge ~ ([1]), Honghanlie ~ [2], Li Jiaju ~ [3] ) Has been introduced. Full-spectrum fitting The Rietveld method uses the scattering information of the entire diffraction space and fits the diffraction spectra of the experimental data with multiple models with different physical meanings. The fitting process uses the non-linear least-squares fitting algorithm to continuously adjust the parameter values in the model, and finally the experimental data and the model calculation values reach the best agreement. The Rietveld Act has now been considered as one
