扩张

Third part: The relationship analysis of city expansion and the suburb farm development. First of all, city expansion has the characteristic of gradualness, regional, universality and integration. The city expansions effect is enlarging city scale, increasing the urban population and so on, Compared with other type farm, the suburb farm, lying in the city peripheral, has relatively developed economy, multipliable industrial structure, the better market growth and high the productive forces level. The city expansion changes greatly suburb farm strategic environment, urges the farm adjust its strategic development pattern.

第三部分：城市扩张与城郊农场发展关系分析，首先分析了我国城市扩张的阶段性、区域性、广泛性和一体性的特点，城市扩张的效果是城市规模扩大，城市人口增加等，然后说明了与其他类型农场相比教，城郊农场处于城市周边，经济相对发达，产业结构多元化特征明显，市场发育较好，生产力水平较高，城市扩张大大改变了城郊农场的战略环境，促使其战略发展模式的调整。

On such a basis, the expansion rate map was drawn to show the dominant direction of urban expansion. The results show that the urban built-up areas have continued to increase, and the expansion was directed mostly southeastward from 1973 to 1986, westward from 1987 to 1993, and southward and southeastward from 1994 to 2001. The rapid increase of population is thought to be the most important driving force of urban expansion.

研究结果表明，长沙市建成区总面积不断扩展，其中，1973~1986年扩张主要表现在东南方向，1987~1993年为西部方向，1994~2001年南和东南方向成为快速扩张方向；对长沙城市扩张驱动力进行分析，认为人口迅速增加是城市扩张的最主要驱动力。

After administerded for 30 days, all rats were killed and anatomized. The nephric exterior of model control group rats was offwhite, instead, that of Yi Shen Granule groups rats showed red grain in offwhite exterior. There were tumefaction of tissue and sediment of adenine in all kidney.

The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 130dB infrasound treatment In 1 day group, Bcl-2mRNA and P53mRNA were expressed lightly in CA1-CA3 areas in hippocampus and dentate gyrus. Blood vessels dilated lightly. In 7d group, Bcl-2mRNA and P53mRNA were more expressed in areas mentioned above. Dilation of capillaries and small vessels was more obvious. Bcl-2mRNA and P53mRNA were strong positive in endothelial cells of vessels. In 14d group, Bcl-2mRNA and P53mRNA expression was obviously increased in pyramidal cells of hippocampus and granular cells of dentate gyrus, showing deep blue staining. a The endothelial cells in some vessels were also strong positive for Bcl-2mRNA and P53mRNA. Dilation of capillaries and small vessels was lessened. In 21d group, Bcl-2mRNA and P53mRNA expression was decreased in pyramidal cells. In 28d group, little change about the expression and distribution of Bcl-2mRNA and P53mRNA was observed. Lots of Bcl-2mRNA and P53mRNA were scattered in cortex of temporal lobe around hippocampus and callosal gyrus area. Dilation of capillaries and small vessels was lessened obviously. The expression of Bcl-2mRNA and P53mRNA in hippocampus after 16Hz, 90dB infrasound treatment.

If it is mainly extrahepatic biliary diffuse stenosis, it will gradually expand upward and downward along bile duct by Bakes biliary duct dilater after the bile duct is cut in surgery ( Including the sphincter of Oddi expansion,the dilatation should be gradual and slow. Too much strength will result in biliary rupture with vascular hemorrhage). T-tube is then placed to support drainage.

若主要是肝外胆管弥漫性狭窄，手术时在切开胆总管之后，以 Bakes 胆道扩张器沿胆管向上、下方向逐步扩张（包括对 Oddi 括约肌的扩张，扩张时应渐次、缓慢的进行，不能过分用力以致胆管破裂及伴行血管出血），然后放置 T 型管支撑引流。

Methods The microcirculation through the Laser-Doppler Flowmetry, and the vessels of the expanded skin were measured at the different degrees of overinflation where the infused volume and the expanded skin area as its criterion.

In the fifth chapter,we study dipolarizations in some quadratic Lie algebras.Inthe first section,we obtain some results on the classification of dipolarizations in gen-eral quadratic Lie algebras,and prove that there exist dipolarizations in the solvablequadratic Lie algebras whose Cartan subalgebras consist of semisimple elements.

第五章讨论了某些二次李代数的双极化，在第一节中，我们给出了二次李代数的双极化的一些分类结果；特别证明Cartan子代数是由半单元组成的二次李代数上存在双极化，第二节确定了四维扩张Heisenberg代数的所有双极化，在第三节中，我们构造了2n+2维扩张Heisenberg代数的六类双极化，我们发现两个不同于半单李代数情形的有趣事实：（1）在扩张Heisenberg代数上同时存在对称和非对称双极化；（2）对应于扩张Heisenberg代数的双极化的特征元有的是半单的有的是幂零的。

From 6860 to 3170 cal.yr BP,semi-desert steppeexpanded,regional montane forest steppe retreated,suggesting a prolonged warm and dryclimate.Between 3170 and 2340 cal.yr BP,regional forest steppe expanded whereassemi-desert steppe retreated,indicating the climate became cool and wet gradually and thehumidity reached the maximum at the end of this stage.During 2340～1600 cal.yr BP,Poaceae steppe dominated whereas wetland meadow expanded and the montane forest stepperetreated,suggesting a cool and wet climate prevailed,wormwood grass steppe prevailed andthe climatic instability increased after 1600 cal.a BEThe climate and environmental reconstructions by pollen were supported by the diatomrecords.A relative high lake level and moister climate prevailed between 8660 and 7230 cal.yr BP as inferred by the dominance of planktonic diatom genera and high planktonic/benthicratio (〉40).low lake level and dry climate sustained during 7230～2330 cal.yr BP assuggested by the low abundance of planktonic diatom and low planktonic/benthic ratio ～20and the lake returned to high level during 2330～930 cal.yr BP as inferred by there-dominance of the planktonic diatom and the high value of palnktonic/benthic ratio.The pollen-based climate reconstruction was also consolidated by the grain size andPediastrum concentration records.

Ugii Nuur湖周围现代孢粉研究表明：松属为空气传播的外来花粉，其含量变化可能指示了远山森林草原发育状况；禾本科具显著低代表性，母体植物建群时含量通常在10％以下：藜科花粉含量可以指示区域气候干旱程度。2、以现代孢粉研究为基础、可靠AMS~(14)C年代为框架，Ugii Nuur孢粉记录高分辨率地重建了蒙古国中部地区过去8660 cal.yr BP以来的植被和气候变化。8660～7800 cal.yr BP研究区植被为禾草草原，湖畔及河谷低地发育苔草草甸，远山发育松属针叶林和森林草原，气候温和略湿润；其中8350～8250 cal.yr BP湿生草甸扩张，旱生植物成分减少，气候凉湿。7800～6860 cal.yr BP旱生成分增加，气候转向暖干。6860～3170 cal.yrBP半荒漠草原扩张，远山森林草原退缩，山地草原和河谷及湖畔湿生草甸退缩，气候持续暖干。3170～2340 cal.yr BP半荒漠草原退缩，远山森林草原扩张，气候转凉变湿，末期湿度条件达最佳。2340～1600 cal.yr BP禾草草原发育，湖畔及河谷低地湿生草甸扩张，远山森林草原略有退缩，气候总体较凉湿。1600 cal.yr BP以来研究区发育禾草-冷蒿草原，气候波动较大。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
