冈村枝管藻孢子体的形态和超微结构

从日本冲绳采回枝管藻，用毛细管将成熟多室孢子囊挑出，在试验室条件下培养，可长成孢子体．用光学显微镜和透射电子显微镜观察发现：孢子释放后形成盘状体附着在基质上，念珠状同化丝从盘状体中间分生．同化丝可从中间部位产生分支，多室孢子囊位于部分同化丝的近端部；同化丝大量产生后基部细胞平行排列，中空，形成假薄壁组织，而后孢子体进入伸长生长阶段；在每个盘状体细胞和同化丝细胞中都有多个色素体和线粒体，蛋白核突出于色素体其他部分，类脂体存在于类囊体中；在同化丝的细胞壁上存在缺口；对同化纤毛而言，色素体和线粒体数量少，紧贴细胞膜，质壁分离严重，在细胞壁上存在“通道”．     

Andreev-Fano Effect in a Hybrid Normal-Metal/Superconductor Interferometer

We report on a new type of Fano effect, named as Andreev-Fano effect, in a hybrid normal-metal/supeeconductor (N/S) interferometer embedded with a quantum dot. Compared with the conventional Fano effect, AndreevFano effect has some new features related to the characteristics of Andreev reflection. In the Iinear response regime, the line shape is the square of the conventional Fano shape, while in the nonlinear transport, a sharp resonant structure is superposed on an expanded interference pattern, which is qualitatively different from the conventional Fano effect. The phase dependence of the hybrid N/S interferometer is also distinguished from those of all-N or all-S interferometers.     

用于ψ＇→γ＇xcJ→γ＇γJ/ψ过程中多极分析的产生子

为了实验研究粲偶素ψ＇级联衰变过程ψ＇→γ＇xcJ→γ＇γJ/ψ,一个用于正确描述全部末态角分布的产生子是必要的．可以通过分析角分布的关联来确定这一过程的多极展开参数（或者等效的螺旋度振幅），而从中可以知道高阶电磁多极矩和相对论修正的贡献，同时可以检验ψ＇是不是ψ＇（2S）和ψ＇（1D）的混合．介绍了一个能完全描述这一过程的角分布的产生子，同时讨论了测量多极参数的测量方法．这些都可以被用在BESⅢ或者CLEOc的分析当中．

Sn-C60薄膜的紫外吸收光谱和X-射线衍射谱分析

对Sn-C60薄膜进行紫外可见光吸收，X-射线衍射和扫描电镜的测定结果显示，薄膜样品紫外可见光吸收的两个短波段吸收峰比纯C60薄膜的吸收峰显著下降，说明Sn-C60薄膜的电子光吸收跃迁为间接跃迁，能带中有杂质能级的存在；样品的X射线衍射峰则对应于面心立方结构；扫描电镜结果显示薄膜为纳米级颗粒组成。     

Effect of the Electron-LO-Phonon Coupling on an Exciton Quantum Dot

The influence of the electron-LO-phonon coupling on energy spectrum of the low-lying states ofan exciton inparabolic quantum dots is investigated as a function of dot size. Calculations are made by using the method of few-bodyphysics within the effective-mass approximation. A considerable decrease of the energy in the stronger confinement rangeis found for the low-lying states of an exciton in quantum dots, which results from the confinement of electron-phononcoupling.     

关于PFI-代数与剩余格

本文提出了一种强FI代数-PFI代数,并且深入研究了它的性质,借此进一步揭示了FI-代数和剩余格之间更加密切的联系,进而以FI-代数为基本框架建立了R0-代数、正则剩余格等逻辑系统的结构特征(包括对隅结构)及其相互关系．这种以FI-代数为基础来统一处理剩余格和R0-代数的方法,同样适合于格蕴涵代数和MV代数等代数结构,而且从中更能清楚地看出它们之间的密切联系,也将有助于对相应形式逻辑系统与模糊推理的研究．     

Spectrum Simulation of Li-Like Aluminium Plasma

X-ray emission spectra for L-shell of Li-like aluminium ions are simulated by using the flexible atomic code based on the collisional radiative model. Atomic processes including radiative recombination, dielectronic recombination, collisional ionization and resonance excitation from the neighbouring ion （Al^9＋ and Al^11＋ ） charge states of the target ion （Al^10＋） are considered in the model. In addition, the contributions of different atomic processes to the x-ray spectrum are analysed. The results show that dielectronic recombination, radiative recombination, collisional ionization and resonance excitation, other than direct collisional excitation, are very important processes.
