The silhouette of object on the turnable stage has been observed from multiple views through rotating. A bright background has been used to improve the contrast of images. An acquiring and processing system has been built. The 3D reconstruction algorithm has been studied based on Shape from Silhouette, and a 3D octree volume element structure model has been achieved through refining. The data will be used in 3D model repairing of laser scanning method.

本文采用单个固定CCD摄像机与转台相配合的方式，实现对物体轮廓图像的多角度采集，并使用背景照明来增加轮廓的清晰度，建立了一套自动的多视角轮廓3D测量系统，通过逐级细化的方式获得物体八叉树体元结构的三维模型，用于激光扫描法的数据修补。

Based on the ITS sequences,the phylogentic tree of these species was constructed using the nrDNA ITS sequence of Ulothrix zonata as the outgroup.

通过实验分析莱茵衣藻1个种和互连网获得衣藻属15个种及丝藻属1个种，共17个种的nrDNA ITS序列，并以U.zonata为外类群，采用计算机分析软件包对其进行分析及构建分子系统发育树图。

The universal primers of ITS1 and ITS4 for fungi were used in amplification of genomic rDNA sequences. A target fragment was obtained by ITS-PCR. Then, the fragment is cloned into the vector of pMD18-T before sequencing. The result of sequencing showed that the fragment is 692 bp in length. The results of Blast in Genbank and the analysis of fungal rDNA systemic development show that the relation between this fragment to the fungi of Sporisorium is closest, while the relation between it to the fungi of Ustilago is much far. It suggests that the name of Ustilago scitaminea for sugarcane smut isn't consistent to the result of rDNA systemic development analysis. It still needs more experiments to support this hypothesis.

用真菌rDNA序列分析的通用引物ITS1和ITS4，通过ITS-PCR得到目的片段，克隆在pMD18-T载体上后进行测序，结果显示该片段的长度为692 bp，与Genebank中已报道的真菌序列进行Blast和系统发育树分析，表明所获得的序列与Sporisorium属真菌具有更高的亲缘关系，而与Ustilago属真菌的亲缘关系较远，这与一直沿用的甘蔗黑穗病菌的命名似乎并不吻合，有待进行更多的研究以证实。

Some morphologic and anatomicalcharacteristics were in common with xerophobous characteristics, which illuminatedthat Malania olefera had some capabilities to adapt to calcific mountains arid livingconditions.

蒜头果在根、茎、叶、花、果实、种子的形态和解剖上既具有原始的性状，又具有进化的特征，对铁青树科分类系统的研究有着重要的意义。

TaYAB1 and TaCRC may play important roles in transcription and transcription regulation during the establishment of abaxial-adaxial polarity in wheat.KeywordsWheat;YABBY gene family;TaYAB1;TaCRC;Bioinformatics

本研究以TaYAB1与TaCRC为研究对象，利用生物信息学方法，对这2个基因编码的蛋白结构与功能进行预测，同时构建其同源基因的系统进化树，从而为揭示小麦侧生器官背腹极性建立的分子机理提供重要资料。

All 13 strains can agglutinate the red blood cell of chicken and human O type. However, their ability of agglutinating the erythrocytes of swine, horse, cow, rabbit and guinea pig were variable.

为了分析分离毒株的流行病学来源及它们之间的相互关系，我们对13 株F 基因1-374bp 的片段进行同源性分析比较并绘制了系统发育树。

For real-time recognition, both the accuracy and the distortion invariant ability can be improved by using the bifurcating tree discriminant classification algorithm based on the multi-sample training with typical distortion images.

采用基于典型畸变图象的多样本训练的二叉树鉴别分类方法，则提高了实时识别系统的准确性和抗畸变能力。

Our company takes cultural marketing system of four-dimensional economy as the core," the tree is brilliant in a century that inherit, if cast the green for a long time family estate ", with the enterprising spirit of " striving, pioneering and inventing, being practical and high-efficient, pursuing being outstanding in coordination ", it put forward " with setting up by bodying, with sincere to treat by people, by rule of virtue enterprise " slogan,it is " know whether there are peoples not to establish, if have both ability and political integrity ", thus realize company of " deal in continuously forever, favour pool world " wish the scene.

本公司以四维经济文化营销系统为主，秉承&树百年辉煌，铸长青基业&的发展理念，以&协同拼搏、开拓创新、务实高效、追求卓越&的企业精神，提出&以诚立身、以诚待人、以德治企&的口号，树立&知人善用，德才兼备&的人才观，从而实现&永续经营，惠泽世界&的公司愿景。

Wavelet packet decompresses vibration signals, and wavelet packet nodes which are sensitive to the change of state, as eigen-nodes, form a decomposition tree; the signal restructured at all eigen-nodes can be used as the fingerprint in many breaker diagnostic systems. Support vector machine with the "most important" factors at eigen-nodes as input vector classifies the states at "one to others" strategy.

首先利用小波包分解振动数据，提取状态变化敏感节点作为特征节点形成分解树，利用敏感节点重构完好状态振动信号，并以此作为当前大多断路器诊断系统中使用的指纹信号；同时提取特征节点最大系数形成特征向量，作为支持向量机的输入向量，使用&一对其余&策略进行特征分类。

Since all of the trees are open we can clean up the trees a lot more, removing redundant abilities.

由于在这种系统中所有的技能树都是开放的，那么我们就可以很方便的把一些冗余的技能清理掉。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
