The feature point in affine scale-space has higher repeat rate under nonisotropic geometric transformation and the ellipse window of nonuniform Gaussian kernel on characteristic scale is founded on image contents.

仿射尺度空间上的特性点在非同向性几何变换中具有更高的反复率，并且其特性尺度上的非统一高斯核椭圆窗口是基于图像内容的。

The bending problem of simple-supported parallelogrammic plates on Winkler foundation is reduced to two simultaneous Fredholm integral equations of the second kind by applying Green quasifunction method. The Green quasifunction is set up by using the fundamental solution of Poisson equation and the normalized boundary equation.

应用准格林函数方法，即利用方程的基本解和规范化的边界方程构造一个准格林函数，将Winkler地基上简支平行四边形薄板的弯曲问题化为两个耦合的第二类Fredholm积分方程，此积分方程的核表示式在区域的边界上具有奇异性。

In order to solve the important and basic problem of the petrogenesis of "Tiantangzhai migmatitic granite" in the core of Dabie orogenic belt, the detailed 1∶50000 regional geological surveying and the big scale dissection of important region (metamorphic rocks, granites and structure), were operated in about 900km〓 area near Tiantangzhai peak. On the bases of the petrology, mineral chemistry, geochemistry of rare earth element and microelement, isotope geochemistry and chronology, physicochemistry, magmatic dynamics, geodynamics, diagenetic simulation, and regional geophysical data, the theory of cooling age and historical geochemistry and the viewpoint of tectonic evolution are applied to study the petrogenesis of Yanshan epoch granites of this region. On the bases of above studies, the process of tectonomagmatic dynamics after indo-Chinese epoch in Dabie orogenic belt is discussed. The important conclusions are gotten

From normal to hyperplastic epithelia, and to squmous carcinoma, the density of pisum sativum lectin receptors on cell and nuclear membrane tended to increase gradually.

发现从正常食管上皮、增生食管上皮到癌，细胞膜、核膜的豌豆凝集素受体呈递增趋势。

After 24 hours, cells had pseudopodia, and exhibited fusiform or polygon-shaped with one or two nuclei. Cells rapidly grew, and formed cell cluster within 3-4 days, and lamellar finally.

h后肾上皮细胞伸出伪足呈梭形、多角形，具有胞核一两个，细胞大小均匀，生长迅速，三四天后形成细胞簇，最后肾上皮细胞连接成片生长。

Two pathways may belong to the same functional system, though they have some architectural difference. It has been disscussed that some neural structures in the visceral afferent pathway may have some relation to the somesthetic afferent.

在梭形细胞的树突上见到较多的对称性突触，突触前末梢含有多形性囊泡；在卵圆形细胞的远核区和树突上，常见到含圆形囊泡的末梢，与胞体和树突形成不对称性突触。

In addition, higher enantioselectively was obtained when the groups on the oxazoline ring were less sterically demanding. That is, substrate will be closer to the backbone of ferrocene.

我们发现当恶唑啉上取代基立体位阻减小时我们发现当恶唑啉上取代基立体位阻减小时，产物的对映选择性就会相对较高，因而平面手性的影响很可能就是通过二茂铁非取代茂环和底物及亲核试剂之间的相互作用而产生的。

Although tau deposits are found in neurofibrillary plaques and tangles in Alzheimer's disease but not in late-onset PD, tau mutations on chromosome 17 are linked to frontotemporal dementia with PD (FTPD-17) and to progressive supranuclear palsy, which are both neurodegenerative movement disorders like PD.

尽管tau沈淀物在阿默海滋氏症的神经纤维性斑块和团块中被发现，但是在迟发性帕金森氏症中没有发现。位於17号染色体上的tau基因突变与伴有震颤麻痹的额颞性痴呆以及进行性核上性麻痹有关，这两种疾病同帕金森氏症一样，都属於神经变性运动失调的疾病。

A series of copper halides in one, two, or three dimensions have been successfully synthesized such as rhomboid dimers of stoichiometry [Cu2X2L2]n, the tetranuclear species on cubane or stepped cubane tetramers of stoichiometry [Cu4X4L4]n and hexagonal[Cu6X6] grid chains.2 The main strategy in crystal engineering is a secondary building block approach.3 For a given building block, there are two routes to construct frameworks.
