We find that the specific magnetization σof the composites decreases exponentially with the increase of concentration of SiO2 particles, and the effective permeability μ of the composites can be agreement with the effective media theory improved by Musal.

通过对颗粒复合体比磁化强度、磁导率、磁谱以及77K下I~U特性的测量和分析，我们发现复合体比磁化强度随SiO2含量的增多呈指数衰减；用Musal改进的有效介质理论模型能很好地拟合磁导率随锰锌铁氧体含量变化的规律；颗粒复合体显示出共振型磁谱的特征。

These results demonstrate that the PsbS protein is located within PSll-LHCll supercomplex and lies between PSll reaction center complex and peripheral antenna complex LHCll.

这些结果证明，PsbS位于PSll-LHCll超级复合体中，并且在PSll反应中心复合体和外周天线蛋白复合体LHCll之间。

There was no typical Golgi complex in oogonia, but there were some Golgi vesicles. At the early stage of vitellogenesis, Golgi complex was abundant whose saccules increased to more than ten layers. At the middle stage of vitellogenesis, Golgi complex grew more in numbers and got together, so its secreting quickened. Moreover, it formed a number of Golgi vesicles, which were filled with granule substances that changed into yolk granule finally.

卵原细胞内无典型的高尔基复合体，但具高尔基囊泡；卵黄发生早期，高尔基复合体发达，膜囊数达10多层；卵黄发生中期，高尔基复合体分泌活动加快，产生大量的大小囊泡，囊泡内充满颗粒状物质，最后演变成卵黄颗粒。

Nano-Metre Size TiO2/Al2O3 complex Support was prepared by improved Sol -Gel method.The structure composition and distribution state of complex suppor t were invesigated by XRD.XPS and IR.At the same time,the effect of mechanical g rinding method and other factor effecting on composition change in preparation w ere researched.

采用溶胶-凝胶法成功制备出纳米尺寸的TiO2/Al2O3复合体，并用XR D、XPS和IR等手段研究了复合体的结构组成及TiO2和Al2O3的分布状态，进一步探讨了机械研磨法制备TiO2/Al2O3复合体等因素对其组成的影响。

In the end, the synthesis condition and influential factors of PU-titania (TiO2) process, such as manufacturing sol (including the amount of water, the amount of PU/Titanium butyrate, the concentration of the solution, the pH value, the kind of alcohol), aging process, theoretical analysis of the dipping process, dry and heat treatment of the gelation, were also discussed especially. FT-IR、SEM、TEM、DLS techniques were applied to analyze and study the reaction mechanism and watch the surface and section of the PU-TiO2 membrane. According to above, it was inferred that PU-TiO2 membrane (containing K600) was better composite.

本文采用原位合成法制备了聚氨酯-二氧化钛水分散复合体，并着重对影响制备稳定透明的复合体的因素（包括加水量、醇的加入量、pH值、聚氨酯/钛酸四丁酯投入量、醇种类）进行讨论，利用红外光谱技术分析聚氨酯-二氧化钛分散复合体的结构，动态光散射技术与扫描电镜分别表征复合分散体的粒径大小与分布及复合膜的表面形态，结果显示含K600的聚氨酯-二氧化钛体系复合情况良好。

The results show that soil-root complex still comply with Coulombs law; root-soil complex cohesion and the incremen in the unit soil content directly proportional relationship, and the root system anchoring role formula is established based on this; Different distribution methods in root has different impact on the shear strength of composite material.

结果表明，根土复合体仍然符合库伦定律；根土复合体粘聚力的增量与单位土体中根系的含量成正比关系，在此基础上建立了根系锚固作用公式；根系不同的分布方式对根土复合体的抗剪强度有不同影响。
