The results showed that the biological activities are closely related to the steric conformation and distribution of electrostatic potential of carboxyl group: The coplanatity between the group of C-3 position and the parent nucleus and the coplanatity between the group of C-3 position and C-4 keto group are very important for biological activities.

结果发现该类药物的抗菌活性与C 3位的空间构象和静电势分布有着紧密的联系。C-3位羧基与C-4位酮基共面性、以及它和母核共面性对抗菌活性十分重要，C-3位两个氧原子周围较强的负静电势也是影响活性的重要因素。

With selection, evaluation and the continuous self-pollination, two whole female parent lines were developed. Line A is green base fruit and hairless surface with few convexities, while line B with green base fruit and short thin thorn.

为此，我们于2000年从引进国外10品种，对此进行系统观察、鉴定、评价，通过连续自交的方式，纯化亲本，选育成A型果实基部绿色，果面有稀疏瘤突、无刺毛，B型果实基部绿色，果面有稀疏瘤突，且有短细刺毛的二个全雌性自交系亲本。

The foundation of arch dam usually is layer rock base, and the depths of the layer are small, it is common that several layer rock base contact with one layer element grid. According to the geometry relation and the property of shape function, a new element kind that includes 24 nodes has been proposed to dissect the dam and foundation effectively, whose shape function are independent. In fact the element can be looked as a hexahedron divided into five small hexahedrons. It can be simulate all kind of the condition of the base and the dam.

拱坝的地基一般是层状岩石地基，有的层厚度很小，这样就有多个岩层和坝体某层单元接触，本文根据岩基与坝体接触的几何关系，利用形函数的性质，提出24节点六面体层单元，这种单元实际上是将一个厚的六面体单元分成5个更薄的六面体单元而形成的，其形函数采用可以拆分的形式表达，因此可以方便地解决坝体单元的一、二、三、四个面与错动带接触的情况，可以模拟一、二、三、四个棱边与错动带接触的情况，还可以退化为12节点的四边形面单元，以及五面体层单元。

In addition, an improved rough fabrication method called "photo etching" is developed to enhance the milling efficiency for prefabricating the rectangular micropillars which can be polished through the FIB microscope for the finishing step.

压缩变形后SEM观察发现在(01 0)柱面出现平行的滑移线，在(0001)基面出现成60o相交的滑移线。迹线分析表明：当加载面为(2 0)时，两组滑移系(10 0)[1 10]和(1 00)[11 0] 同时开动。

On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。
