The model was preprocessed to assure the regulation of facets, create the dual graph of it, and then adapt Reeb Graph to extract the skeleton which contains enough information of the model, such as gesture and topological features, to be able to be used as descriptor of 3D model retrieval.

通过对模型进行一定的预处理保证面片的规则，定义面片间距离计算方法，创建模型的对偶图，识别连通分量，在连通分量上应用Reeb图的计算思想抽取原模型的骨架。试验表明，该算法具有较好的计算效果和效率，最终的骨架保存了模型的拓扑连通性以及姿态，可用于基于内容的三维模型检索时的特征描述符。

For example,the graph in Fig.3-5 is Hamiltonian（a possible path being P→Q→R→S→T→P）but is not quite Eulerian,since any path which includes every dege exactly once（e. g.P→Q→T→P→S→R→Q→S→T）must end up at a vertex different from the initial vertex.

例如，图3-5所示是一个哈密尔顿图（存在一条路P→Q→R→S→T→P）但不是一个欧拉图，这是因为图中任何包含所有边一次且仅一次的路（如P→Q→T→P→ S→R→Q→S→T）都不能回到原出发顶点。

RT-3DE shows clearly full view of the primary atrial tumor than two-dimensional echocardiography and obvious image differences between atrial myxoma and malignant atrial tumor. It is a convenient, quick and precise modality for diagnosing primary atrial tumor and may be of significant clinical value for the diagnosis of primary atrial tumor.

Nighty rats were randomly divided into the groups of control, myocardial infarction and doxycycline, which were given orally 48 hours before and 48 hours after MI with 30mg/Kg per day. Protein and mRNA extraction was done on left ventricular samples containing scar and myocardium together. Samples were assayed from 1 day to 4 weeks post-Mi. The activity of MMPs was measured by zymography and collagen amount by the method of chloramine T, the ratio of II III collagen was assessed by immunohistochemical stain. Protein and mRNA of MMP-2, 9, TIMP-1 were determined by Western-Blot and RT-PCR.

红外光谱分析结果表明，山楂叶原花青素产物1、产物2的红外谱图与原花青素A类相似。

Image analysis system was used for semi-quantitive assay of TGF-βRⅠ and R Ⅱexpression, and microphotography was used to record the morphologic changes of culturedchondrocytes. The results are:1. TGF-〓 showed sequentially inhibitory and promotive effects on the proliferation of human articular chondrocytes of two week monolayer culture from one passage to eight passage.

After the cell growth curves was recorded, RPE cells of the 3-5th passages were utilized. 2、Three different siRNA (siRNAl,siRNA2,siRNA3) targeting against human cx43 gene and one negative control siRNA were designed and transfected into cultured human RPE cells via liposome reagent. The most effective siRNA can be determined by semi-quantitative reverse transcription PCRRT-PCR. 3、To the most effective siRNA, after transfected into human RPEs with different concentration, the cellular proliferate activities were messured by MTT colorimetry ; the percentages of RPE in different cell circle phase was assayed by FCM; the changes of phenotypical properities were observed with SCM; the protein expression of cx43 was studied through immunocytochemistry stain and Weston blot; the communication intercellular was calculated with FRAP; and the ability of recovery was assessed by using an in vitro wound healing model.4、The total proteins of siRNA1 and RPE were seperated by two-dimensional gel electrophoresis and visualized by silver staining. Proteins with significant expression alterations were selected and their peptide mass fingerprints (PMFs were obtained by matrix-assisted laser desorption/ionization time of flying mass spectrometry (MALDI-TOF-MS).The PMFs were used to search NCBInr database by Auto MS-Fit software.

In order to conserve raw materials, reduce costs, at the time of the first three days of mathematical seihan "the regeneration of positive PS plates, each 印张 essentiallythe with a overprinter version is enough (with the exception of special circumstances), and the eye for an eye" on the selection of mathematics is a new version of positive YP-IIPS, as a result, with positive YP-IIPS Edition plates made of plates might as well have ratooning positive PS Edition plates.

为了耗费原质料、贬低本钱，制版时《初三数教上》采取了复活阳图PS版，根基上是每个印张用一套印版不离不足了，而《月朔数教上》采取的是陈的阳图YP-IIPS版，甘休，用阳图YP-IIPS版制成的印版的耐印力还不如复活阳图PS版的耐印力。

In contrast, cultivated provenances had low genetic differentiation perhaps due to coancestry. The UPGMA analysis revealed that the cultivated provenances from Kenya and Tanzania might have originated from native provenances from East Java, Lombok, Bali, and Sumbawa. The native provenances from Timor revealed geographic relationships among these islands.
