Formation Mechanism and Orderly Structures of an Iron Film System Deposited on Silicone Oil Surfaces

A new iron film system,deposited on silicone oil surfaces by vapour phase deposition method,has been fabricated and its formation mechanism as well as orderly structures has been studied,It is found that the formation mechanism of the films obeys a two-stage growth model,which is similar to that to the other metallic films on liquid substrates,Large and orderly structures are observed in the continuous iron films.The experiments show that the orderly spatial structures result from the local material gathering in these nearly free sustained films.     

卓艺：坚持Hi—Fi精品的路线

经营之法各种各样，据说松下创始人松下幸之助看到庭院水景，悟出“清浊并吞、随方则圆、上波下静”的经营之道。其实这就是中国先哲所谓“上善若水水自流”的别解，商品质量、公道价格和优质服务是营销必需的“三大件”，但还是不够，来的都是客，朋友即财源，这是我们的“店规”。     

类锂铝复合机制产生X光激光的等离子体状态

本文从速率方程出发,讨论了类锂铝复合等离子体的激发态结构,衰减常数,反转率和小信号增益等表征介质增益特性的物理量以及它们随电子温度,电子密度和光子逃逸几率的变化。找到了进行类锂铝离子通过复合机制产生X光激光设计应创造的等离子体状态目标区域。还讨论了这些物理量随原子序数变化的定标律。     

用Technicolor理论研究稀有辐射衰变Bc→Dsγ

在一代Technicolor(TCI)和带有一个无质量的标量二重态(TCⅡ)模型下,计算荷电的哥尔斯通粒子对衰变B_c→D_sγ的贡献,并把它们同标准模型的计算相比较,发现哥尔斯通粒子对电磁企鹅图的贡献很大(TCI下),在TCⅡ下贡献较小;而对弱湮没图的贡献可以忽略不计,还对同位旋三重态粒子π+p的质量进行了约束. 预言将来在LHC上能对不同模型下的分支比Br(B_c→D_sγ)的差异进行研究,进而对不同的模型进行检验.     

Evolution of Weighted Networks by Duplication-Divergence Mechanism

The duplication and divergence process is ubiquitous in nature and man-made networks. Motivated by the duplication-divergence mechanism which depicts the growth of protein networks, we propose a weighted network model in which topological evolution is coupled with weight dynamics. Large scale numerical results indicate that our model can naturally generate networks with power-law-like distributions of degree, strength and weight. The degree-strength correlation is illustrated as well. These properties are in agreement well with empirical data observed in real-world systems. Furthermore, by altering the retention probability δ, weighted, structured exponential networks are realized.     

浅析SNMP三个发展阶段的安全机制

一、SNMP的基本概念 网络管理中的简单网络管理协议(SNMP)模型由4部分组成:管理节点(management node)、管理站(management station)、管理信息库(MIB:Management Information Base)和管理协议(management protoco1).
