As such, HMSPP has recently become a hotspot of development in many countries. This review summarizes researches in the past few years on the development of HMSPP, from preparation to property characterizations, with special emphasis given to the in situ polymerization technique to access long chain branched HMSPP.

本文从HMSPP的结构特点、制备方法、性能测试等方面总结了近年来的研究进展，着重介绍了反应器合成长链支化型高熔体强度聚丙烯的方法以及其结构表征，并在总结国内外现状的基础上展望了高熔体强度聚丙烯的发展前景。

Statistical characteristics include Tectonic Density, Degree of Central Symmetry, Skewness Index, Degree of Tectonic Optimal Direction, Power Spectrum Density, Cubic Entropy and so on. The former four indexes are implemented in this paper; Structural characteristics show the characteristics of spatial distribution of geological bodies. In chapter four, a quantitative method for describing geological structure by using the structure "tree" is studied and implemented, including its formalized definition and the measurement of the similarity of different "trees".

统计特征有构造密度、中心对称度、失真指数、优益度、密度功率谱、方位熵等等，本文实现了前四个参数值的提取；结构特征是反映地质体空间分布的结构特点，第四章研究和实现了用"树结构"描述地质结构的定量方法，包括结构的形式化描述和结构的相似性度量。

First, the digraph is used to represent the topology of multi-agent systems, and then, a first-order integrator model and a consensus convergence criterion of systems are established.

首先提出了能使用有向图表示的多智能体网络系统的拓扑结构，并根据该拓扑结构建立了网络系统的1阶数学模型和提出了多智能体网络系统一致收敛准则。

The effect of HO_3OH structure on diol self-association was summarized.

The former is to prepare polymolybdates coordinated' directly by organic ligands using Na2MoO4 and MoO3 precursors; The latter plays emphasis on exploiting a simple and effective routine to synthesize Keggin polytungstates in which the transition metal or Si acts as the heteratom by reaction precursor Na2WO4.We have synthesized a 4,4'-bipyridine bridging dumbbell-like polymolybdates a metatungs...

前者主要是制备有机配体键合的多金属钼酸盐；后者重点是探索出一个简易、有效的合成过渡金属或主族元素硅作杂原子的Keggin多金属钨酸盐的方法，然后通过变换过渡金属或有机配体的种类探讨对产物结构的影响，再对所得化合物的结构和组成通过物理测试手段进行表征，同时研究其在光、电、磁等方面的性质。

Namely,spinous setae mainly distributed on the legs of Cybister bengalensis,acetabula setae distributed on the legs of male Cybister bengalensis,and bunchy setae only distributed on the nick points of the pronotum and the elytra.

采用体视显微镜、扫描电镜技术观察并描述了黄缘真龙虱体壁表面各部位的形态结构特征，发现了3种典型的凹陷和普遍存在的凸起，了解了其三维结构，分析了凹陷与龙虱水生生活的关系。

From the above observations, it is evident that Golgi body-like structrue present in encycting trophozoites are absent in the log-phase trophozoites, and the components of the Golgi body like structure are not synthesized in the process of encysting, indicating that they may be a temporarily assembling event in a specific stage of encystation.

在蓝氏贾第鞭毛虫成囊过程中，高尔基体结构成分无大量合成，出现的类高尔基体结构可能是各组分临时组装的结果。

Each of these bundles is called a nucleosome, and many nucleosomes are bound together by the continuing strand of DNA, which forms a string of beads that further coils to form one of two kinds of chromatin, either euchromatin or heterochromatin.

所有细胞核的最显著的特点就是染色体，由DNA和组蛋白所组成的染色质构成，DNA绕行在由4个相似的组蛋白分子结合而形成的柱状的芯上，这一结构称为核小体，核小体之间由连续的DNA链连接，形成串珠样结构，进一步盘曲形成常染色质或异染色质。
