A cell is not just a well-mixed container of chemicals, but an extremely intricate system of membranes, vesicles and signaling pathways. Although a number of milestones have been built though endeavor for over a century, much is still left to discover about the spatial organization and mobility of macro-molecules (such as proteins, protein complexes, nucleic acids, signaling substances, etc.) in cells, and the spatial relationships between cells in tissues.

细胞不仅是大量化学物质的容器，也是膜、泡囊和信号传导通路组成的复杂系统，尽管通过一个多世纪的努力，细胞生物学研究取得了若干重大进展，但是关于细胞内特定高分子(如蛋白质、蛋白质复合体、核酸和信号传导物质等等)的空间组织和运动规律以及组织内细胞空间关系等许多问题的机理目前仍不清楚。

Two of properties of spatial reasoning are spatial relation's uncertainty and computational complexity.

空间推理的不确定性和推理计算的复杂性是地理空间推理的两个基本特点。

There are many influences for relation's uncertainty in spatial reasoning, and the three most important influences are the data uncertainty and acquiring difficulty of relation information and result uncertainty of spatial reasoning.

空间推理问题的不确定性的主要原因是数据的不确定性、关系提取的困难性和推理过程的不确定性，这三种不确定性因素都影响到了地理空间推理中的地图目标空间关系发掘和提取，同时，计算的复杂性也是影响地理空间推理系统应用的一个重要因素。

To investigate the spatial-dependence of heterogeneity at multiple scales for a community, we selected a representative plot of 100 m×100 m in the mountainous evergreen and deciduous mixed broad-leaved forest in Sichuan, southwest China (102°50'E, 30°02'N).The location of every tree was mapped by compass, and all-scale analysis of spatial structure of forest community was conducted by the method of PCNM (principal coordinates of neighbor matrices).

为了解植物群落在多尺度下的空间变异规律及其对空间尺度的依赖，以川西南山地阔叶混交林为对象，在有代表性的地段设立100m×100m样地，采用传统的罗盘仪对树体的相对空间位置进行定位，运用主轴邻距法(principal coordinates of neighbor matrices， PCNM)对群落空间结构的多尺度（100m内）特征进行了研究。

By means of 10m spatial resolution SPOT images themajor rupture zone can be revealed distinctly, meanwhile, 1m spatial resolution IKONOS images display the fine structures and kinematical characteristics of the surface rupture of the earthquake.

应用高分辨率卫星影像进行地震地表破裂带解译，10m分辨率SPOT卫星影像能够清楚地反映出地震地表破裂主破裂带的形迹， 1m分辨率IKONOS影像能反映出地震地表破裂的精细结构及运动特征。

This articles main innovation is to have independently developed a set of distributional spatial data integration software from the first floor, has constructed the spatial information application service platform prototype based on the SIG frame city by using this software, and has solved the distributional isomerism space data conformity demonstration and in the client side realize to the far-end data operation and so on the essential technology.

本文的主要创新之处在于是从底层自主开发了一套分布式空间数据集成软件，利用该软件构建了基于SIG框架的城市空间信息应用服务平台原型，解决了分布式异构空间数据整合显示及在客户端实现对远端数据的操作等关键技术。

The software is constituted a set to have three structures patterns (the customer level, the logical level and the data level) the distributional spatial data platform software, this software mainly by based on number according to the data searches the module, isomerism space data conformity module, the spatial data browser three big modules constitutions.The paper altogether divides five chapters.

软件由基于元数据的数据查找模块、异构空间数据整合模块、空间数据浏览器模块构成，利用该软件能开发出具有三层结构(分别为客户层、逻辑层和数据层)模式的分布式空间数据集成平台。

Many tree species at the same time and solve the spatial heterogeneity which empirical method could not achieve. Therefore, the assessment method could be applied in the selection of species for afforestation or species selection in the forest restoration areas.From collecting the attributes of planting species, spatial distribution data and environmental factors, we could integrate and analyze the data for further simulating the forest dynamics of forest in Taiwan. The impact of global change on forest also could be evaluated.

应用生育地因子评估树种之生态地位，能解决统计实证方法在空间异质性使用的限制，并可同时评估多种树种，因此可应用在造林树种之选择，亦可应用於崩塌地复育造林树种之选择，以及林相改良造林树种之选择，在收集更多树种属性与空间分布资料后，配合此评估方法，未来更可模拟出台湾森林之动态，以及评估环境变迁对台湾森林所造成的影响。

For the leaf area index of the three forest types, there was a similar variation trend, i.e ., increased first and decreased then, with the maximum presented in mid-July or August for Q. mongolica and J.mandshurica forests while in mid-August or September for F. rhynchophulla forest. The canopy porosity of the three forest types also had a similar variation trend, but opposite to leaf area index, being decreased first and increased then, with the minimum presented in mid-June, July, August or September. The analysis of variation coefficients of leaf area index, transmitted direct gap light, and transmitted diffuse gap light indicated that the spatial pattern of leaf area index in July-September was the main factor affecting the spatial distribution of transmitted diffuse gap light.

结果表明，3种林型的叶面积指数变化总体趋势是一致的，均呈先上升再下降的单峰曲线，蒙古栎林和胡桃楸林都是在7月中旬或8月中旬达到最大峰值，花曲柳林是在8月中旬或9月中旬达到最大峰值；3种林型冠层孔隙度的变化总体趋势也是一致的，呈先下降再上升的单峰曲线，不同样地峰值出现的时间也不同，最低峰值在6、7、8、9月中旬均有出现；通过对不同月份的叶面积指数、林下散射光、林下直射光的变异系数分析表明，7—9月叶面积指数的空间格局是影响林下散射光空间分布的主要因素。

"Second Life is remarkably easy to work with, and is very popular,"

"第二次生命是显着容易的工作，并且很受欢迎，"

For example, we usually assume that materials are homogeneous and isotropic and free of internal defects or flaws.

为了得到适合有限元分析的模型，我们必须经过如图2所示的简化步骤。
