用MATLAB绘制粒度分布R-R-B线图 Drawing Grain Size Distribution R-R-B Line Diagram by MATLAB

粒度特性方程是研究表述散状物料粒度特性的主要方法，目前用的较多的是R-R方程式。本文介绍了目前通行的R-R-B图画法，然后详细说明了用MATLAB软件编程绘制了R-R-B图的新方法，并实验对比了两种方法的拟合效果，得出了使用MATLAB拟合的优点。 The grain size characteristic equation is the main method to study the grain size characteristics of granular materials, and the R-R equation is used. This paper introduces the current R-R-B drawing, the programming with MATLAB software rendering the new method R-R-B graph is described in detail, and the fitting effect of two methods is experimentally compared which shows the advan-tages of MATLAB fitting.
