摘要
建立了粒度分析曲线的非线性回归模型,用Gauss—Newton法确定了最优化参数,用汉化的Turbo—Pascal(V5.0)语言完成了数据处理及图形绘制和打印的程序设计。
A non—linear regression model about partical degree analysis curve has been established. Pertineat optimum parameters have been determined with Gauss—Newton Method as well. A program design has been achieved which deals with the entire process of data processing, graphic plotting and graphic printting etc with Turbo Pascal(V5.0) Laguage.
