Quantum Games of Continuous Distributed Incomplete Information

We study two-player quantum games of incomplete information in which both the sides have partial information.The previous results of Du et al. [Phys. Rev. E 68 (2003) 016124] are incorporated in our more general formalism.Because of different roles played by the total information uncertainty and the information asymmetry, the game exhibits many interesting features.     

浅谈里德伯常数

 1.里德伯常数的由来用光谱仪分析氢放电管和某些星体的光谱,即可获得H原子光谱。瑞士科学家巴末尔长期研究原子光谱线。1884年6月25日在巴塞尔自然科学协会的演讲中,他公布了一个关于氢光谱波长规律的经验公式。同年又发表在当地的一个刊物上,1885年又刊载在《物理杂志》上,他根据实验结果得出在可见光区的氢光谱分布规律的经验公式:λ=Bn2n2-22,式中B是一常数,等于36456纳米.     

两个回归函数相等的Bootstrap检验

两个回归参数相等性检验一直是统计界感兴趣的问题之一．在这篇文章中，四个检验统计量被用于度量两曲线的差异，在原假设下统计量的分布采用向量数据的重复抽样来逼近，并给出了—些模拟结果．     

Multiple Scattering Effects of Ag Particles in Random Ag-SiN Film

A layer of 40nm-thick Ag-SiN film with Ag nano-particles embedded and distributed randomly in the SiN thin film were deposited by the method of radiant-frequency magnetron sputtering. Specimens orderly comprising a random Ag-SiN film and an optical phase change recording layer were exposed to a focused laser beam with wavelength of 69Ohm. It is shown that, with a random Ag-SiN layer deposited above the recording layer. Calculation by the finite difference time domain method of a 4Ohm-thick SiN film under a Gaussian beam irradiation has been carried out to simulate the near-field distribution in the film, which showed a huge local near-field intensity enhancement of about 200 times if small Ag particles with diameter of 6 nm were modelled inthe SiN film in the central region of the in cident laser spot.     

相干态光场的位相统计性质

根据Pegg-Barnett位相定义，计算了相干态光场的位相概率分布函数，并且进行了数值模拟。研究表明在真空态时，位相分布曲线为一条直线；相干态下位相分布曲线表现为：均匀分布→泊松分布→均匀分布。     

从二项式分布推出高斯分布

在实验中,对一个物理量在同一条件下进行测量次数很多时,测量值或随机误差通常遵守高斯分布。为简化引入该分布的手续,本文从二项式分布出发推出高斯分布。一、回顾二项式分布对一个随机事件,在同一条件下进行N次独立的试验,若以试验结果事件A发生的概率为P,A不发生的概率为(1-P),
