浅析塔克拉玛干沙漠降水云系特征及演变规律

文章在分析前人研究成果的基础上,总结归纳了塔克拉玛干沙漠降水云系的基本类型、特征、环流形势和云系演变的一般规律.云系类型归纳起来可以分为四大类:冷锋涡旋云系类,南支槽盾状云系类,大槽、低涡云系类,副热带西风急流云系类.这四类云系只要进入塔里木盆地活动,都会影响塔克拉玛干沙漠降水或大风、沙尘天气.

Relations between structural properties and synchronizability on local world dynamical networks

In this paper,the effects of various structural properties on the synchronization of coupled oscillators with local-world coupling configurations are investigated.It is found that for local world networks,the larger heterogeneity of the degree distribution,the enhanced interconnection of nodes,and the increased clustering do not improve the synchronizability of dynamical systems.On the con- trary,the increase of the maximum betweenness centrality appears to be responsible for the decrease of the synchronizability.     

Theoretical research progress in complexity of complex dynamical networks

This article reviews the main progress in dynamical complexity of theoretical models for nonlinear complex networks proposed by our Joint Complex Network Research Group (JCNRG). The topological and dynamical properties of these theoretical models are numerically and analytically studied. Several findings are useful for understanding and deeply studying complex networks from macroscopic to microscopic levels and have a potential of applications in real-world networks.

一种局部集聚的网络演化模型

著名的局域世界演化模型提出了局部演化的思想,但其局域世界的选取方式却不太符合现实世界的情况.由此提出了一个改进的局域世界演化模型,生成的网络同时具有无尺度和小世界特性,其度分布也同样表现为幂率和指数之间的某种过渡,而相对于原模型,却具有大得多的聚类系数,这符合真实世界的情况,使得本模型更有应用价值.     

对中学足球队员掌握规则的调查

运用调查法、文献法、数理统计法，对重庆市几所中学的足球队员掌握规则的状况进行分析。发现队员由于受知识的局限性，对足球竞赛规则的掌握程度较差，甚至于有些比赛中非常简单的常识性规则也没能够掌握好，势必会给比赛带来诸多影响，并针对此提出解决措施。     

覆岩离层分布时空规律的实验研究

通过相似材料物理模拟实验研究，揭示了煤矿区采动覆岩中离层产生、发展与分布的时空规律；探讨了离层发展高度与工作面推进距的关系、单一离层从产生到最大值直至消失的时间效应等规律。并提出了可充填离层带的概念，为离层充填减沉技术在理论上的完善及其在解决实际工程问题中的应用提供了科学的依据。
