摘要
针对在土的颗粒大小分析试验中人工计算及绘制颗粒大小分配曲线 ,其过程繁琐、效率低下、容易出错的问题 ,阐述了在计算机上如何利用三次样条函数数学模型绘制颗分曲线 ,并计算出Cu/Cc值的原理和方法。
In accordance with the manual calculation and drawing the grainsize curve is troublesome and easy to make mistakes. In this paper, how to use mathematical model of cubic spline in calculator to draw the grain size curve and the principle and method to find outCu/Cc are presented.
