摘　　要：介绍了原煤可选性曲线的常用绘制方法。尝试了新的曲线拟合方法,即运用差分进化算法,对模型函数的参数寻优,当拟合误差最小时,得到模型参数值。根据拟合好的模型函数,编写MATLAB程序绘制可选性曲线。结果表明,差分进化算法拟合的可选性曲线准确性好、曲线平滑,对选煤生产具有重要意义。Some common methods of plotting raw coal washability curve has been introduced and a new fitting method was attempted.The Differential Evolution Algorithm is applied to optimize the parameters of model function.When reaching the minimum fitting error,the value of parameters of model function is obtained.According to the fitted model function,the curve of raw coal washability is plotted by compiled MATLAB program.The result showed that the curve of raw coal washability fitting by Differential Evolution Algorithm is quite smooth and has good accuracy,which has significance for guiding coal preparation plant production.
