The results showed that there were significant differences among parameters of texture feature of the different land utilization. In the desertification, the mean and variance were comparatively high. The gray level was asymmetry, the contrasts between neighboring pixels were significant; while in water and irrigable land, the mean, variance was a little bit low, the grey level was symmetry; the mean, variance and gray level in the forest and dry land was between the above (desertification and water and irrigable land).

不同土地利用类型之间纹理特征参数差异明显，荒漠化土地的均值、方差值较高，灰度分布不均匀，相邻像元反差明显，内部变化剧烈；水体和灌溉耕地的均值、方差值很低，灰度值均匀，内部变化小；林地和旱耕地信息介于上述两类土地之间。

The value of a scalar variance at a general point can be estimated from the measurement at a limitary data points,and the deviation between the estimated value and the measured value is the least.

XRD indicated that the replacement of the terephthalate anion by the polytungstate anion had little effect on the structure.

结果表明，经过同多钨酸根阴离子的交换以后，垂直于水滑石层板方向的平行层板方向的晶格参数值变小，平行层板方向的晶格参数值不变，(003)、(006)、(009)衍射峰处的层间距值比为3：2：1；交换过程没有改变水滑石的结构，水滑石原位生长在γ-Al2O3表面及内孔，比表面积由γ-Al2O3载体的219m2/g增加到247m2/g，孔径分布则由原来的2～11nm变化为3～4nm。

The capacity of single pile will enhance when the length and diameter of pile increases, but effect of pile diameter is more obvious. While pile diameter increases 20、40 and 60 percents, the capacity of pile will enhance 20.4、53.7 and 78.1 percents. And with the effect of mud-cake, the capacity of single bored pile will fall down nearly 20 percents, and pile-side resistance will also reduce 15 — 35 percents. In the centrifuge tests, when the relative displacement between pile and soil was 45 —85mm, which is much more than the criterions, the pile-side resistance will become most. Meanwhile the intenerated value of utmost resistance is close to the resistance in situ. In the pile group tests, the capacity of pile group , which the space among piles increases from 2D to 3D、 4D and 5D , will enhance 6.1、9.6、18 percents .

当桩径增加20%、40%、60%时，桩承载力分别增长了20.4%、53.7%和78.1%；在考虑泥皮效应后单桩侧摩阻力减小15～35%，极限承载力减小18%～24%，且减小率随桩径的增加而变小；试验中桩身侧阻软化值与原型桩实测侧阻软化值接近，且极限侧阻所对应的桩土相对位移试验要比规范值大得多，约为45～85mm；同时群桩极限承载力随桩距的增大而增加，其中桩距为3D、4D、5D的群桩承载力分别比间距为2D的群桩高6.1%、9.6%和18%；其承载力效应系数η接近或大于1，并随着桩间距的增大而不断提高；群桩侧摩阻力沿深度的分布与单桩略有不同，即桩身上部由于承台的作用，侧阻削弱，但桩身中部侧阻具有增加的趋势。

A novel least squares algorithm based on anti-WKB method and linear segment interpolation,which is called prediction-verification method, is proposed.This method takes the values calculated by anti-WKB and linear segment interpolation as approximation,then uses the least squares fitting,and after that compares the linear segment interpolation based on the anti-WKB method with it.
