This article focuses on the line-line, line-region and region-region topological relations algorithm, which come down to the same question: whether there are intersections between line and line. The sweep-line algorithm was studied by many people, but has some deficiencies to be improved, in order to handle some special cases and increase program efficiency. My works as follows: rectangular envelope to reduce executive times , vector cross multiplication to determine intersection between line and line, coordinates and slope method to deal with some special cases. C program examples are showed together.(5) Finally, to prove capability and efficiency of the model and calculation method, some test systems are developed. For example, complex spatial topological relation query, parcels' exact area with the area of linear object reduced in land use, quality inspection to cadastral data according to topological rule, spatio-temporal change query of cadastral data.

将线线、线面、面面之间的拓扑关系实现的算法归结为线与线之间求交的基本问题；为处理一些特殊的拓扑关系情况，提高扫描线算法的效率，探讨了包络矩形粗滤、判断线线是否相交的矢量叉乘法、线节点重合或共线的斜率坐标判断法等改进方法；同时还设计了一种新的节点微小圆求交的算法，可应用于图斑与线状地物细分拓扑关系及地类面积的计算；（5）本文设计了实验系统，包括复杂对象的拓扑关系表达与计算程序、图斑地类面积的计算程序、基于空间拓扑关系规则的地籍数据库质量检查功能，以及时空拓扑关系和变化语义分析等原型，验证了拓扑关系表达模型和计算方法的可行性和实用性。

The GDP per capita and per unit area of each county was in inverse proportion to the value of ecosystem services per capita and per unit area, which implied that the higher GDP was, the more severe contamination of environment was.

各县人均及单位面积生产的GDP与单位人口及单位面积分配的生态系统服务功能价值成反比关系，GDP越高所对应的环境污染也相对较大。表1图11参12。

Look at Picture 3.4—2. Compare the area of Square ABCD with the sum of the areas of four same right-angled triangles , and what inequality can you have?

Quantification of the bone ingrowths of PCHA was increased about eight times than CHA.

CHA的骨生长仅发生在材料与骨界面之间，材料中心始终无骨生长；计算机病理图象分析结果表明：骨内植入16周时，PCHA的新骨生长面积（占骨缺损面积的32.20±1.47％）比CHA（占骨缺损面积的3.91±0.68％）大8倍。

RCBV values calculated using cSVD and oSVD were identical. Both values were equal to the whole areas under the concentration-time curve were divided by the arterial input function areas. Moreover, these rCBV approximated to the rCBV calculated by signal-time curve fitting. rCBF with cSVD and oSVD wouldn't be underestimated by delay effect and were good for relative quantity. The scatter plots of rMTT and Td were useful in stroke staging.

Film, sulphuric acid paper haihong-type: this type of original, exposure time, should be carefully handle, because some of the pictures and texts used in film than sulfate for paper document the required exposure time to increase twice as much, or even better, this type of original in exposed not only to ready a sheet of typing paper to retaining to part of the exposure time, but also to prepare a ratio of sulphuric acid paper size large waste PS version mastering sulfuric acid paper blocked the view of typing paper, and the film also exposure, this piece of PS version is good to all of retaining this side of sulfuric acid paper for extending the original copy for the last half of the original version, so that the exposure time of light and dark sides.

软片、硫酸纸参半型：这栽典范榜样的原版，在曝平工夫上，更答不苛澈底不天把持，因为用软片的一些图不白给比用硫酸纸的图不白所需曝平工夫给补充二倍，甚至更众些，这栽典范榜样的原版在曝平时，不但给绸缪好一张打字纸来挡去一局部曝平工夫，而且还给绸缪一块比硫酸纸面积稍不小一不面的宝PS版，在把持好硫酸纸遮关打字纸，而软片一面还给曝平的环境下，这块PS版不离起到残部挡好硫酸纸的这边，以延不幼软片这半版原版的曝平工夫，使双方的图不白深浅分歧。
