Synthesis of nickel(II) complexes of alpha-isoxazolylazo-beta-diketones and their absorption of spin-coating films and thermal properties for HD-DVD-R

Three kinds of new nickel(II) complexes of alpha-isoxazolylazo-beta-diketones with blue-violet light absorption were synthesized. Their structures were postulated based on elemental analysis, MS and FT-IR spectra. Smooth films on K9 glass substrates were prepared using the spin-coating method. The absorption properties and thermal stability of these complexes were discussed. The static optical recording test for high density digital versatile disc-recordable (HD-DVD-R) system was also studied. (c) 2005 Elsevier B.V. All rights reserved.

异构分布环境下的远程协作系统(HD-RCS)

分布环境下的应用处理与资源共享将面临不同层次的异构性（包括：数据库层，操作系统层和网络层），为此我们提出了一种基于客户／服务器结构的远程协作系统，该系统是建立在数据库远程过程调用（ＤＢＲＰＣ）的机制之上的，其特点是通过其底层的抽象通信平台（Ｓｔｅｐｇａｔｅ）能实现与各种网络协议的互联。同时也能支持其上层应用系统对各种远程资源（数据资源、操作处理资源等）实现同步或异步远程访问与操作。进而支持异构分布环境下的资源共享与分布处理。
