为了避免磺酰氯化合物发生水解、醇解和胺解等衍生化反应影响磺酰氯化合物分子结构表征，本文采用衍生化反推法证明了β-萘酚结构磺酰氯化合物的分子结构，并利用红外光谱、核磁共振氢谱、质谱表征了含β-萘酚结构磺酰胺染料的分子结构。

The relationship between inter-story torsion angle and torsion deformation ratio is deduced base on the rule of irregular plan structures in China tall building technical specification. Considering the inter-story ratio limitation of different performance levels under different earthquake hazard levels, a series of torsion angle demand curves are established and a new method named as Torsion Angle Capacity Spectrum is put forward for the PBSD of irregular plan frame structures.

从现行规范对平面不规则结构的限制条件出发，推导出了结构层间扭转角与扭转位移比的关系式，结合框架结构在不同性能水平下的层间侧移角限值，建立了平面不规则框架结构在不同地震作用水平下的扭转角需求曲线，提出了扭转角能力谱法。

我们选择不同的结构和生长序列的几个典型的超细钛纳米线，即四边形、五边形和六边形序列，以及六边形序列的两个较大体系，以分别考察结构和尺寸效应。

BRICKWORK_STRUCTURES_DESC;Vaults and cylindrical structures used in medieval churches needed this technique of bricklaying to form its structures without angularity.

中世纪不带棱角的拱顶和圆柱建筑需要这种砌砖技术。

We find in form, the surface parts which are put in front of the time marks of the two structures are antithetic of affirmation and negation; in content, these two structures fully show their complementary distributions with their process meaning and critical meaning. And the essence of the complementary distributions is the contradiction of one-way dimension of objective time and inverse subjective thought.

从形式上看，在"没有VP之前"与"VP之前"结构的时间标记之前的表层成分是否定和肯定的对立；从内容上看，尽显"没有VP之前"与"VP之前"各自独立品格的是过程意义与临界意义的互补分布。

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.

首先，经过对北京山区水源林天然林和人工林结构要素的演替动态研究，提出其发展规律，同时依据水源林结构与功能耦合关系研究，从林分层次和流域层次上分别构建了水源林的理想结构，其中，林分层次上水源林的理想结构为：异龄、复层、混交的结构状态，林分结构趋于天然林结构的特征；在流域层次上水源林的理想结构为也应形成&复层&、&异龄&、&混交&的结构，即：在流域各水源林斑块间形成林冠层复层、斑块内部乔木、灌木、草本层的复层；不同水源林年龄面积上的均匀分布；形成不同水源林斑块间的镶嵌分布。
