The unified symmetry of mechano-electrical systems with nonholonomic constraints are studied in this paper,the definition and the criterion of unified symmetry
Interaction between transmission control protocol (TCP) and random early detection (RED) gateway in the Inteet congestion control system has been modelled as a
A diode-end-pumped Nd:YAG dual-wavelength laser operating at 1319 and 1338 nm is demonstrated. The max-imum average output power of the quasi-continuous wave li
We propose the methods of generating multipartite entanglement by considering the interaction of a system of N two-level atoms in M cavities of high quality fac
This paper demonstrates an approach that negative uniaxial crystal has a relative anomalous dispersion effect which can compensate group velocity delay, and app
This paper proposes a novel quantum-behaved particle swarm optimization (NQPSO) for the estimation of chaos’unknown parameters by transforming them into nonlin
<正> 山城重庆以多雾而知名,天然的、社会的、政治的雾,浓而厚密,压得人喘不过气。当然重庆也有短暂的晴朗日子。当以毛泽东为首的中共代表团来到重庆同蒋介石国民党谈判时,当周恩来、董必武、王若飞、叶剑英、陆定一、吴玉章以及许多同志来渝,同国民党展开针锋相对的斗争,并向知名文化界、民族资产阶级、民主党派代表、进步工人解释我党方针、政策时。可惜人们头一次听到这许多立论新鲜、透彻有理的言论,脑子里还来不及消化,毒雾又开始弥漫山城了!
The relation between the excitonic purity and the concurrence in a system of two coupled large semiconduction quantum dots mediated by a single-mode cavity fiel
利用借音壮字考察其造字时代的汉语音,是研究粤语方音史的一种新途径和新方法,对中古汉语的研究也具有价值。本文尝试讨论利用古壮字研究广西粤语方音史的方法。
