区域土壤腐蚀试验数据分布特征研究——Ⅱ位置分布特征表述

将区域腐蚀试验数据看作是连续、光滑变化 的土壤腐蚀性-位置函数具体数值，用三次样条函数处理塔里木地区库尔勒-库车公路沿线土 壤腐蚀试验数据，得到插值公式并计算最高腐蚀性土壤的位置和腐蚀分区边界等.同样思路 也适用二维位置分布研究，但复杂得多.本文还介绍三角网格线性插值和绘制平面等值线图 等一般方法.

DISTRIBUTION CHARACTERISTICS OF CORROSION DATA OF REGIONAL SOIL TESTS --Ⅱ Characterization of Position Distribution

The soil corrosion data collected along Kuerle-Kuche Highway at Tarim area were regarded as individual values of a soil corrosivity-position function that was continuous and smooth.The cubic spline functions were applied to fit the data.The interpolation functions were obtained and the positions with maximum soil corrosivity or the boundaries for seperating areas with different corrosivities were calculated.The analogous methods were also suitable for analysis the two-dimensional position distribution,but much complex.The general methods about triangular net interpolation and plot of plane diagrams with soil corrosivity contour lines were also introduced in the paper.
