结果表明，以土壤有机质和农用地类型为协因子的球状模型Cokriging总体插值精度最高，试验区内土壤有机质分布格局是四周丘陵和水库区含量较低，巴江河两岸的平原地区、西南角的山前冲积平原含量较高，这也是灌溉水田密集的区域；试验区内土壤有机质含量菜地分布比较均匀、空间相关性很强，而水浇地分布差异较大、空间变异性较高；土壤有机质分布在南北、东北-西南两个方向相关性较强具有各向同性特征，在东南-西北、东西方向具有各向异性特征，受到随机因素的影响变异性较大。

In this thesis, an improved method is proposed to overcome the problem that the circular color histogram method does not take the spatial information of colors into account , combines spatial distribution information with image color features. The presented method adopt color space which has the visual uniform , three components carries on no laddered quantification, three components weighting summation composes the row of the circular color histogram construction, and improves retrieval quality, while rotation and translation invariance of color histogram are kept.

针对颜色直方图对图像的空间信息表现不够的问题，本文提出并实现了环形颜色直方图的改进方法，将图像颜色特征和颜色的空间分布信息相结合，采用具有视觉一致性的颜色空间，并把各通道分别进行非等间隔量化，采用各通道向量加权的形式把各通道组合为一个特征向量，提高了检索质量，并保持了原有算法的有效性和旋转不变性。

Based on the 1950-1998 SST and NCEP/NCAR reanalysis data, the temporal/spatial variations of SSTA in the Western Pacific Warm Pool region have been analyzed in this paper by means of the methods of EOF and composite analysis. Results show that there are two main spatial patterns of the WP SSTA: one is uniform in the whole region, the other is meridionally anti-symmetric.

采用海温资料和NCEP/NCAR 49a再分析的高度场、风场资料，利用EOF、合成分析方法，研究了夏季暖池SSTA的时空演变，结果显示：夏季暖池SSTA具有整体一致性分布和南北区域的反对称分布两种空间分布型。

Postoperative contrast sensitivity testing showed statistically significant differences (P＜0.05)between the two IOLs at 12 and 18 cpd under photopic, at 1.5and 3 cpd under mesopic, and at 1.5 and 3 cpd under mesopic with glare conditions.· CONCLUSION: The Tecnis Z9000 IOL proved to have statistically significant superior contrast sensitivity to the 911AIOL at high spatial frequencies under photopic conditions and at low spatial frequencies under mesopic and mesopic with glare conditions.

术后对比敏感度分析发现两组在12和18 cpd、1.5和3 cpd以及1.5和3 cpd均有统计学差异(P＜0.05)结论：Tecnis Z9000 I0L被证明其对比敏感度在明视高空间频率和暮视低空间频率方面均显著优于911A IOL。

Different definitions of spatial weight directly influence on Moran's I, analysis and view on the problems of spatial relationship.

空间权重定义的不同将直接影响Moran's I指数的值，进而影响对空间相关性问题的分析和认识。

The dissertation deduces that inner mechanism of the legal system interact one another to construct the spatial continuance and transformation and the intention of spatial evolution of Taiwan's courthouses, including several critical affected factors:the scope of law, the source of law, the instance level of court, the court proceedings, the contentious or nonlitigious legal affairs, the civil or criminal procedure and tribunal.

进而推论台湾司法建筑空间形制的延续、转化与此变迁的动向，正是由法制思维的内涵机制交织作用所致。其关键影响项目包括法源；司法建筑所属之审级组织；审理程序；所受理之诉讼或非诉讼法律事务，与所展开民事或刑事诉讼程序及法庭等。

The center technology is spatial OLAP and spatial OLAM on the basis of GIS.

因此，建立集成空间信息分析处理的智能决策支持系统是极其必要的。

The spatial structure of genetic diversity among 17 populations of Cryphonectria parasitica in China was investigated using RAPD markers with the spatial autocorrelation analysis.

应用空间自相关分析方法对中国栗疫病菌 17个居群 RAPD遗传变异的空间结构进行研究，以探讨栗疫病菌居群遗传变异的分布特征及其形成机制。

The average taxonomic distinctness Δ+ was the highest in the southern Yellow Sea and lowest in the central Yellow Sea; the spatial variations were largely caused by the different spatial distributions of species belonging to orders Perciformes, Pleuronectiformes, Clupeiformes and Scorpaeniformes, especially those of cartilaginous species.

在区域尺度上，分类多样性指数Δ，分类差异指数Δ+在黄海中、北部较高，南黄海较低；等级多样性指数Δ+为南黄海最高，中黄海最低，其区域尺度变化主要是由鲈形目、鲽形目、鲱形目和形目种类，特别是软骨鱼类的种类数的分布变化造成的。
