双层结构的

This dissertation summarizes all kinds of topological relationships and spatial operations, and uses the conception realms to design the data structure of spatial region objects, and devises the red、blue planar graph algorithm, and makes use of red and blue sweep-line algorithm to implement the spatial topological analysis operations on layers of region objects. At the end, further works and improvements are presented.

本文 对空间拓扑分析操作进行了归纳总结，并且基于 Realms 概念探讨了空间区域对象的数据结构以及红蓝区域平面图算法，文章详细讨论了针对双层红蓝区域对象的各种空间拓扑分析算法的实现，最后是该类问题的进一步改进和构想。

"This new approach gave us dramatic new insight, because we could actually see the lipid molecules gathered around the protein, and see them form the characteristic leaflets of the bilayer biological membrane."Roderick MacKinnon

Dinoflagellate have many traits different from prokaryotes and eukaryotes:the cells have nuclei, but the nuclear membrane is discontinuous; There are many chromosomes in the nuclei, but the chromosomes remain permanently condensed during cell cycle; The cristae of mitocondria is tubular, and the cells have no typical endoplasmic reticulum.

甲藻细胞虽有核膜，但双层核膜不连续；有多个形态结构完整的染色体，但染色体在整个生命周期中永远处于高度凝集状态，DNA纤维的折叠方式与典型真核生物中期染色体完全不同；线粒体的嵴为管状。

At first, using the gravitation mode the article confirms the range of Xi'an district, then the article carries on the analysis of the distance optimizing, economic linking, perimeter urban industry basic and water resources protection, then propose " a pair of axis "and" a pair of level " mode, and establish the xi'an satellite city, they are Xianyang, Lintong, Changan, Yanliang, Gaoling, Huxian, Xingping , Liquan , Jingyang , Sanyuan , Qianxian. Then on the basis of analyzing the industry shift of Xi'an, he article confirm the function of every satellite city; At the same time point out the study and adjust of Xi'an satellite city should be strengthened, and strengthen the industrialization construction of the infrastructure, then propose to build one pair of rings structure of traffic facilities.

文章首先应用引力模式确定西安都市区范围，继尔经过优化距离分析、经济联系紧密度分析、周边城镇产业基础分析及水资源保护限制分析后，提出了&双轴线、双层次&发展布局模式，确立了西安包括咸阳、临潼、高陵、户县、兴平、礼泉、泾阳、三原、乾县、阎良、长安十一个卫星城；继而在分析西安市产业梯次转移的基础上，确定了各卫星城的职能；同时指出要加强西安卫星城基础设施发展的研究及调控，要加强基础设施产业化建设，提出建设交通设施的双环结构。

The results for the double-ayered show that, owing to the presence of concrete outer layer of the shell, the maximum boundary stress of steel is reduced to about 20—25%, and the pressure distribution between these two layers takes the sha...

在此基础上，作者提出了计算双层蜗壳的近似方法。在三夹层蜗壳的试验中，测量了内外层钢板的应力，发现这种结构不仅在工艺上有其特点，而且能在很大程度上消除蜗壳边界的应力高峯。
