The effects of thepreparation conditions on the structures and performances of the sol samples were studied,followed by investigating the formation mechanism of the anatase TiO_2 particles. Thecharacterization of the as-obtained sol-gel samples shows that the TiO_2 and P-doped TiO_2sols have anatase crystal structures, and the latter has higher crystallizability than theformer.

第二节分析了瓦当纹饰与建筑遗址的关系，通过对三个国家出土瓦当位置的分析认为，瓦当一般在宫殿建筑或比较高等级的建筑使用。

Some SPR-LI neurons were also positive for TH. After administration of vasopressin, SPR-LI structures became denser, especially at levels of pyramidal decussation and area postrema . The dendrites of motor dorsal nucleus of X in the dorsal part of MVZ appeared thin and straight in morphology instead of curl and thick outlooks. These results implicate that some SPR-LI neurons might receive or regulate the cardiovascular stress information induced by vasopressin.③In PHA-L/FOS/TH triple-labeled experiments, seven kinds of immunohistochemical structures were found in MVZ. They were FOS-LI neurons, TH-LI neurons, PHA-L positive fibers, PHA-L positive fibers terminated on FOS-LI or TH-LI neurons, FOS/TH doublelabeled neurons, PHA-L positive fibers terminated on FOS/TH double-labeled neurons.

在锥体交叉和最后区水平，SPR免疫反应阳性结构较正常组明显增强；背内侧部迷走神经运动背核的SPR纤维也由弯曲的粗纤维变为细的直纤维，30％的SPR阳性神经元为SPR/FOS双标记神经元，提示这些神经元参与感受心血管伤害性刺激信息，继而参与心血管活动信息的中枢传导或整合；③三重标记研究结果显示，在MVZ可见到七种免疫反应阳性结构，即PHA-L，FOS，TH，FOS/TH，PHA-L/FOS，PHA-L/TH，PHA-L/FOS/TH。

Mud diapir structures in Yingehai Basin, South Chia Sea provided better channels for gas migration, so that gas at 3000-6000m depth were migrated to 000m shallow reservoirs throught mud diapir structure s and traped in favourable structures.

莺歌海盆地泥底辟构造为天然气运移提供了良好通道，3000~6000m深处的天然气通过泥底辟构造运移到浅部，并在有利构造部位成藏。

The concept of topology optimization of truss structures with discrete variables including two kinds of variables and the relative difference quotient algorithm for discrete optimization are extended to the topology optimization of plate and shell structures composed by plate and shell elements.

将包含两类变量的桁架结构拓扑优化设计的概念及求解离散优化的相对差商法进一步推广到由板壳单元组成的板壳结构的拓扑优化，建立了包含两类变量的板壳结构拓扑优化设计模型，并采用相对差商算法进行求解。

In [28], the author has proved the feasibility in mathematics. In this paper, we propose a direct sum decomposition algorithm of AFS structure based on the research in [28], which decomposes a complex AFS structure into several independent sub-AFS structures, thus the elements in the same sub-AFS structure are dependent on each other, the elements in the different sub-AFS structures are independent.

本文在文献[28]理论研究的基础上，具体提出了AFS结构直和分解算法，实现了把一个复杂的AFS结构划分为若干个相互独立的子AFS结构，使得同一个子AFS结构中的元素是相互关联的，而不同子AFS结构中的元素是相互独立的，即每个子AFS结构均是一个连通系统，从而有效地降低了分析AFS结构的难度。

It indicates that the N—O bonds in the singlet dimer adsorption configurations are weaker than any other structures, and this is propitious to the NO direct decomposition. 7. Unlike NO molecules interaction with copper atoms, when two NO molecules interact with the adjacent silver atoms, the non-planar structures are more stable than the planar.

同时，单重态的二聚体与相邻的金属铜和银原子作用时，由于电子从金属原子转移到二聚体上的数量最多，因此在这种吸附构型中，金属原子被离子化的倾向最大，同时使得二聚体中N—O键被削弱的程度也最大，有利于NO的直接分解； 7。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
