Abstract  
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.
