在结构上

Rossini inherited the brilliant tradition of Italian classical opera; chose typical characters and events in theme; Pursued its ampleness and showed conditions and conflicts in personalities; Adjusted the inne...

在继承意大利古典歌剧优秀传统的同时，在题材上选择典型的人物和事件，在人物塑造上力求丰满，表现个性冲突和矛盾；对歌剧的内部结构进行了合理的调整，改革了以往咏叹调和宣叙调交替出现，统领一部歌剧的现象；改变了歌唱家为了炫耀技巧而随意改动旋律声部，破坏剧作的统一和完整的现象；增加了重唱与合唱的分量；在歌剧管弦乐的表达上与剧作内容紧密结合，管弦乐为戏剧服务。

However,authors still do not find the relevant references on convergence and symmetric problems of the semi-analytical solution.Based on the semi-analytical solution for Hamilton canonical equation theory,the formulations of the clamp and simply supported and symmetric boundary conditions on the Hamiltonian element are derived by the variational principle.Several numerical examples show that with increase of meshes,the convergence rate of the semi-analytical solution is faster than the convergent rate of traditional finite element method based on displacement.

①在厚度上没有任何位移和应力模式的假设，由于传递矩阵方法的引入，从理论上讲，不受板壳厚度或层合板壳层数的限制；②采用弹性力学的Hamilton正则方程半解析法，可以克服边界的局部化效应[8]；③由于在平面内或圆柱壳的曲面内采用了有限元法，所以一般的板壳问题不受结构侧面边界条件的限制，在复杂工程板壳问题上具有广泛的应用领域。

Composite structure is a new type of structure, which is generated by thecombined precast technology and cast-in-site technology.

这些结果都是基于复杂网络的拓扑结构得到的，然而真实的复杂网络不仅仅具有它们的拓扑结构，还有发生在此结构上的信息和交通动力学，对于社会网络的理解，结点之间连接强度的不同也是尤为重要的。

Genomic DNA in eukaryotic cell is organized into nucleosome array and further packaged into higher-order structures. Each nucleosome is composed of a stretch of approximately 147bp DNA wrapping around a histone octamer, and neighbored nucleosomes are connected by linker DNA with length varies from 20bp to 100 bp.

This paper chooses 2000 stochastic retailing stores whose acreages all exceed 40km2 in the three circles of Wuhan city,after the analysis of spatial difference on acreages,number,population density,and manage forms,and makes a conclusion that the retailing spatial structure of Wuhan city has taken on figure of ring shape with hierarchy wholly and frame of centralization-diffusion and enchasing partially; Finally,the whole paper probes into the change mechanism and trends of retailing spatial structure.

随机抽取武汉市中环线内2000个营业面积大于40m2的零售商业网点，基于统计资料、实地调查，运用GIS空间分析技术，划分环带与格网提取武汉市零售业网点密度、服务人口、营业面积、业态分布、商品特色等空间分布数据，分析零售业网点密度分布的空间特征，得出武汉市零售业在空间结构上表现出整体的等级圈层结构，局部的空间聚合扩散结构和&逆发散特征&——镶嵌结构；最后对其变动的动力机制和演变趋势进行了初步探讨。
