The higher percentage of cross-fertilized kernel specifically expressed pattern was observed in highly heterotic hybrid, after comparison of gene differential expression between cross-fertilized and self-fertilized kernels during the early development of seed in wheat and maize, respectively. This indicated that there may be have common molecular mechanism for heterosis in different crops.

本文对玉米和小麦在种子发育前期杂交和自交间基因差异表达进行了比较，发现杂交特异表达类型与杂种优势均存在一定的正向关系，说明不同作物杂种优势形成在分子水平上具有共同点，即相同表达模式的基因或基因群在不同作物杂种优势形成中发挥一致的作用。

Methods: Rabbits whose allogenic thoracic aorta was cross-linked by dye-mediated photo-oxidation (DMP, n=6) were in the DMP group, rabbits whose allogenic thoracic aorta was cross-linked by glutaraldehyde (GA, n=6) were in the GA group, and rabbits whose homogenic abdominal aorta was orthotropically transplanted (OT, n=6) were in the OT group. Then the donor arteries were transplanted in the position of abdominal arteries of rabbits.

以经染料介导光氧化反应处理的家兔胸主动脉为研究对象，以戊二醛处理的家兔胸主动脉以及自体腹主动脉原位移植作为对照，建立家兔胸-腹主动脉移植模型；实验动物观察饲养1个月后，取出标本，通过原子吸收光谱法测定血管组织钙含量，扫描电镜观察血管壁钙化情况。

As Gudehus-Bauer hypoplastic model can not consider cross-anisotropy of sand, themodel introduced by matrix of cross-anisotropy is improved.

6针对Gudehus-Bauer亚塑性模型不能考虑砂土的横观各向同性效应，提出了在模型中引入一个考虑横观各向同性的矩阵进行改进。

METHODS: The distances from anterior acetabular margin, posterior acetabular margin to anterior inferior iliac spine, iliopubic eminence and pubic tubercle were measured, respectively to determine and make serial cross-sections of the acetabular anterior column. In addition, the safe angle of screw entry on all entry points of each cross-section was measured, and all data were put into software SPSS 10.0 for statistics process.

分别测量20个半骨盆标本髋臼前、后缘到髂前下棘、髂耻隆起和耻骨结节的距离，确定和制作髋臼前柱系列断面，并测量各断面上各进钉点的安全进钉角度，将测量数据输入到SPSS10.0软件进行统计学分析。

In order to enhance the compatibility of ABS/PP/CaCO3 composites, the effects of reactive blends of the composites were studied by using Haake rheometer. The effects of various assistant cross-linkingers, such as castor oil, triallyl isocyanurate, turpentine (JS-1) and glycol dimethacrylate, and the used amount of cross-linkinger-dicumyl peroxide on the torques of the melting composites were investigated.

为提高ABS/PP/CaCO3复合材料相容性，采用转矩流变仪观察了ABS/PP/CaCO3三元复合物反应性共混后的扭矩，考察了不同的助交联剂蓖麻油、异氰脲酸三烯丙酯、松香酯(JS-1)、二甲基丙烯酸乙二醇酯以及交联剂过氧化二异丙苯的用量对共混物的影响。

Two kinds of cross-linked polyacrylate latices with relatively narrow distribution of particle diameters, which are abbreviated to P and P/P, were synthesized by seeded emulsion co-polymerization, respectively.
