摘要
利用多项式插值的方法对击实试验所得五点进行拟合,得到关于含水量y的多项式y(x)=z[0]+z[1]x+z[2]x2+z[3]x3+z[4]x4,通过对每一点的计算比较得到试验的最大干密度和最优含水率。
Fitting the five dots of geo-technical compaction data with multi-nominal interpolation method, the multi-nominal of water content y（x）=z[1]x＋z[2]x^2＋z[3]x^3＋z[4]x^4 was obtained. The maximum dry density and optimum water content were obtained by calculation and comparison of each dot.
