The coherent electron micro-diffraction from a translation domain boundary perpendicular to the direction of the incident beam was studied. The qualitative and analytical descriptions are given to reveal the phenomena on the breakdown of center symmetry and an appearance of the forbidden diffraction spots.

对垂直电子束方向的畴界的特征，进行了实空间法的准动力学的理论推导，给出了对称性的定性描述，同时用动力学多层法程序对一些上下畴界进行了模拟；对出现的斑点不消光，中心对称的破损，镜面对称的破损等给出了定性的实空间法的动力学的理论的解析描述。

Also help the students insight in the 21st century interdisciplinary branch of plant science will be even further infiltrated the differences between various branches and limits and gradually reduce the trend of development.

The analysis shows that the molecule chain coupling is the common feature of the two systems.

结果表明：一定条件下聚合物凝胶和疏水缔造合聚合物溶液具有相似的溶液结构和流动特性；胶态分散凝胶在多孔介质中的流动存在转变压力，2组流动实验中疏水缔合聚合物溶液也表现出类似的转变压力，分析认为聚合物凝胶分子链间的联结是化学交联，而疏水缔合聚合物为物理缔合，类似的分子链间联结方式是两种体系有相似流动特性的内在原因。

结果表明，纯钛种植体与骨结合十分紧密；钛与骨组织间的离子作用是相互的；钛—骨间既存在物理性结合，也存在化学性结合。

BACKGROUND: Early research indicates that chemotactic factors involved in chemotaxis of bone marrow mesenchymal stem cells in vitro.

背景：早期研究表明趋化因子参与骨髓间充质干细胞的体外趋化，确定骨髓间充质干细胞体内迁移的分子机制，对其介导的细胞治疗中枢神经系统损伤和疾病有重要作用。

This study aims to explore the following questions: differences of the genetic polymorphism among seasonal populations; differences of genetic diversity among four age groups and between two different gender populations; testifying the Ford and Chitty hypothesis; the relationship between the genetic diversity and geographic distance; the relationship between the genetic diversity and population density; edge effect on genetic diversity.

主要探讨以下问题：季节种群间遗传多态的差异；种群年龄组和性别间遗传多样性的差异；Ford和Chitty的假说；种群遗传多样性与空间距离的关系；种群遗传多样性与密度的关系；中心区、边缘区和半岛区种群遗传多样性的差异。

The result was not consistent with what was predicted by Chitty's polymorphic behavior hypothesis; aggressive behaviors of dyadic encounters were not correlated to body mass but to the difference of body mass negatively which means that there were more aggressive behaviors between dyadic encounters with similar body mass.

东方田鼠双冲突个体间的攻击水平与其体重的相关不显著，而与冲突个体的体重差异则呈显著的负相关，体重差异越大，冲突个体间的攻击水平越低。
