扩张

The interrelationship between several basic categories in fuzzy topology is made clear in terms of co-tower extension of topological constructs. It is shown that for ever completely distributive lattice L,the the category of L-fuzzifying topological spaces is isomorphic to the cotower extension of the category of topological spaces, and it can be embbedded in the category of L-topological spaces as a simultaneously reflective and coreflective subcategory.

用拓扑范畴的co-tower扩张的概念厘清了不分明拓扑中若干基本范畴之间的关系，证明了对任意完全分配格L， L-模糊化拓扑空间范畴同构于拓扑空间范畴的co-tower扩张，并且可作为一同时反射余反射子范畴嵌入L-拓扑空间范畴中。

At first, we give someelementary conception and properties of Novikov-Poisson Algebras, we elaborate on thegeneral conclusions about central extension and universal central extension in thechapter three.

我们首先给出了Novikov-Poisson代数的一些基本概念和性质，在第三章中详尽地阐述了中心扩张和泛中心扩张的一般结论。

On the base that searchs country firm, both all begin to be the centre of a circle to surround dilate outwards with this, if attentive observation, we will discover both did not distinguish besides search engine quality outside, the includes key of value core, outspread side to wait to having essence distinction of other.

在稳固搜索江山的基础上，两者均开始以此为圆心向外围扩张，如果细心观察，我们将发现两者除了搜索引擎性质没有区别外，其它的包括价值核心、扩张侧重点等都有着本质的区别。

The topical application of tanshinone IIA at one μg/ml and five μg/ml caused significant dose-related vasodilation, indicated by the increased agent/control ratio of arteriolar diameters from 1.0 to 1.25±0.08 and 1.57±0.11, respectively, in the hamster cheek pouch.

Primitive accumulation period of British colonial expansion during this period of colonial expansion, began in the 16th century until the late 18th century in the rise of the industrial revolution.

原始积累时期的殖民扩张英国在这一时期的殖民扩张，始于16世纪迄于18世纪后期工业革命的兴起。

Our data suggest that the site, age, and histological characteristics of the lesion allow us to define VT dilation as a nosological entity distinct from other cystic dilations of the conus medullaris.

我们的数据提示病灶的部位、发病年龄和组织学特点可以让我们将VT扩张作为一个病种从其它的脊髓圆锥囊状扩张疾病中鉴别出来。

Iris Tan of daystar company analyst thinks, giant client group, extensive vendor network and powerful brand acknowledge are spent should meet make the net that carry Cheng farther actual strength of the dilate in the tourism of the China from rapid dilate.

晨星公司分析师Iris Tan认为，庞大的客户群、广泛的供给商网络以及强大的品牌认知度应该会让携程网进一步从迅速扩张的中国的旅游业中扩张实力。

Surface tear of the endomembrane and atherosclerotic plaque induced by balloon dilatation, mechanical expansion and carotid sinus draw-off can adjust compliance of the carotid wall, change sensitiveness of carotid artery receptor, cause instability of hemadynamics and defluxion of plaque fragments, lead to hypotension, bradycardia, hypertension and vascular embolism. How to control and reduce occurrence of above-mentioned complications is a main problem in present studies.

但由于球囊扩张、支架置入机械扩张和牵拉，颈动脉窦引起内膜和动脉粥样硬化斑块的表面撕裂，调整了颈动脉壁顺应性，改变了颈动脉受体的敏感性，引起血液动力学不稳定和斑块碎片脱落，引起低血压、心动过缓、高血压及血管栓塞等并发症，如何控制和减少上述并发症的发生是目前研究的主要问题。

First, For the coronary artery stent, two kinds of loads, including the pressure named 〓 derivatively from the balloon and the counterforce named 〓 on the wall edge of the stent, have been taken into account in the analysis of the stent.〓 and 〓 were changing as the stent expanding. So, the expansion process of the stent could be considered as the process composing of many extremely short equilibrium processes, where 〓 and 〓 could be regarded as constants and the stresses, the strains and the displacements were obtained using NFEA in every processes. Then, the stresses, the strains and the displacements obtained in every processes or steps were added up to get the final structure of the coronary stent.

首先，解决了支架有限元分析的载荷非线性问题，认为医用心血管支架受到两种载荷的作用：球囊直接传递的压力〓和球囊对不锈钢支架丝壁边缘的反作用力〓，这两种载荷在支架分析中必须都考虑进去；〓为非线性载荷，随着支架扩张不断变化，处理时将支架扩张的整个过程看成由37个很短的平衡过程组成，在每个过程中取〓为常量，采用有限元法获得应力、应变、位移，最后将各过程的应力、应变、位移迭加起来就获得了不锈钢支架总的应力、应变和位移；本研究用变分法和有限元法模拟杆件拉伸证明了上述方法是合理的。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
