Statistical characteristics include Tectonic Density, Degree of Central Symmetry, Skewness Index, Degree of Tectonic Optimal Direction, Power Spectrum Density, Cubic Entropy and so on. The former four indexes are implemented in this paper; Structural characteristics show the characteristics of spatial distribution of geological bodies. In chapter four, a quantitative method for describing geological structure by using the structure "tree" is studied and implemented, including its formalized definition and the measurement of the similarity of different "trees".

Durum wheat is tetrapolid (28 chromosomes) and contains two basic genomes, whereas common bread wheat (Triticum spp.) is hexaploid and contains three basic gonomes. Durum is best adapted to growing in arid regions of the world: Italy and other areas in Southern Europe; Turkey and Syria in the Near East; Morocco and Algeria in Africa; Soviet Union; and Canada and Northern United States in North America.

But detail geochemical study indicates (Wu et al., 2002)that those rocks have low Sr〓(0.706), high ε〓(-0.5～-1.9), young age of Nd model age (970-1090Ma) and syngenesis with surrounding I-type granites. The rock originated from partial melting of source igneous rock and belongs to I type granites. The occurrence of high alumina minerals is related to the intense interaction of magma and liquid during the late period of magma evolution, and tetrad REE patterns are formed.

但详细的地球化学研究表明(Wu et al。，2002)，岩体具有低的Sr〓(0.706)、高ε〓(-0.5～-1.9)、年轻的Nd模式年龄(970-1090Ma)及与周围Ⅰ型花岗岩的共生关系，认为岩体是火成岩源岩物质部分熔融的产物，属于Ⅰ型花岗岩，高铝矿物的出现与岩浆演化晚期强烈的岩浆—流体相互作用有关，并形成特征的稀土元素四分组效应。

In this text we used the method of volume integral equation base on tensor Green's function to study the forward of 4D transient electromagnetic response.

The systematic reform and construction of Marxism Philosophy should depend on the management of the following four relationships:(1) the relationship between explanation system and innovation system;(2) the relationship between set system and unset system;(3) the relationship between one system and several states;(4)the relationship between the whole and the parts.

马克思主义哲学体系的改革和建构应依据以下 4个方面的原则：第一，应正确处理阐释体系与创新体系的关系；第二，应正确处理有"体"与无"定体"之间的关系；第三，应正确处理"一体"与"多态"之间的关系；第四，应正确处理整体与分体之间的关系

Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

对导入赖草优质耐盐基因的株系Line15进行了C-分带、荧光原位杂交、SSR相结合的鉴定，确认Line15是一个二体异附加系，附加的一对染色体与小麦的第二同源群长臂、第三同源群着丝粒和第七同源群短臂密切相关，并确定了Line15的外源染色体C-分带特征带型，为目后鉴定Line15附加系的真伪提供了简便快捷的途径；对抗旱附加系Line17进行了荧光原位杂交和SSR检测，得出Line17也是一个二体异附加系，外源染色体与小麦的第四同源群短臂密切相关。

The nano-silica partrcles are organic-modified by E-MA-GMA elastomer through direct solvent process,the organic-modify process mechanism was studied,and the dispersing of modified nano-silica particles in tetrachloroethane solvent and PBT were investigated.FIRT,TEM,SEM results indicated that the epoxy group of E-MA-GMA could react with the hydroxyl groups of silica surface,helped to reduce the interactions of nano-silica particles particles and improve the dispersion of nano-silica on PBT and the interfacia...

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。
