摘要
在Excel中先根据试验数据自动生成击实曲线、趋势线拟合公式,然后用Newton迭代法求解高次方程,得出最优含水率和最大干密度。
In Excel, the automatic generation of test data compaction curve based on the trend line fitting formula firstly, then solve high-order equations with Newton iteration method to obtain the optimum moisture content and maximum dry density.
