Firstly,the sampling design has great impact on the accuracy of remote sensing classification.There exists great randomicity on the result of points and cluster sample verification on the different Sampling design.On the same sampling design,the stability of point sample verification is higher than that of Cluster sample verification.Secondly,the average accuracy of different sampling designs of multi-point and multi-cluster sample verification can reflect the accuracy characteristic.During the course of point sample verification,stratified sampling's error is lower than others'.During the course of cluster sample verification,systematic sampling and stratified sampling's accuracy are prior to simple random sampling's.

研究结果表明：（1）抽样方式对遥感分类精度评价结果的影响是客观存在的，不同抽样方式下的点样本和群样本检验结果都存在一定的随机性，但同一种抽样方式下，点样本检验精度评估结果的波动幅度小于群样本检验，稳定性比群样本检验要好；（2）不同抽样方式下的多次点样本和群样本检验的平均精度检验结果基本上都能够反映分类图像的精度特征，其中，点样本检验中，分层随机抽样点样本检验效果较好；群样本检验中，系统抽样群样本检验和分层随机抽样群样本检验的效果优于简单随机抽样群样本检验。

Alloy of polyethylene of element of the methodological freeboard that make, titanium and sample of alloy of cobaltic chromic molybdenum, FITC of classics of cuticular grape coccus labels, the cuticular grape coccus that after sample of artificial and articulatory material is disinfected, vaccinal FITC labels, sample surface cent is slick surface and rough surface, every groups each 6 sample, brood the 24 orifice plate that contain bacterium and sample below 37 ℃ after Yo 30min, with fluorescent microscope observation, sample uses observation of scanning report lens.

方法制作超高分子聚乙烯、钛合金和钴铬钼合金试样，表皮葡萄球菌经FITC标记，人工关节材料试样消毒后接种FITC标记的表皮葡萄球菌，试样表面分为光滑表面和粗糙表面，每组各6个试样，将含有细菌和试样的24孔板在37℃下孵育30min后，用荧光显微镜观察，试样用扫描电镜观察。

A sequenced method in consideration of the sample range was proposed to rationally array classifiers of a support vector machine with binary tree architecture. A sample distribution radius and a sample distribution distance were introduced to estimate sample range of all classes in high-dimension characteristic space. The classes with bigger sample range were classified earlier in the higher nodal point of the binary tree architecture, and were given wider classificatory areas in the characteristic space.

考虑到样本的分布情况对分类器推广能力具有较大影响，提出一种次序二叉树支持向量机多类算法，采用样本分布半径和样本分布距离估算各个类别的样本在高维特征空间中的分布情况，把分布半径较大的类别或者分布距离较大的类别较早地分出来，并且在特征空间中给其划分较大的分类区域。
