JOURNAL OF COMPUTATIONAL MATHEMATICS

The Journal of Computational Mathematics is an international journal on numerical methods, analysis and applications. It publishs original research papers in English, French or German, but preferably in English. Prom 1998, it has appeared bimonthly（instead of quarterly）.     

Multiparty Quantum Secret Sharing of Key Using Practical Faint Laser Pulses

Based on a bidirectional quantum key distribution protocol [Phys. Rev. A 70 (2004)012311], we propose a (m-1, m-1)-threshold scheme of m (m≥3)-party quantum secret sharing of key by using practical faint laser pulses. In our scheme, if all the m-1 sharers collaborate, they can obtain the joint secret key from the message sender. Our scheme is more feasible according to the present-day technology.     

基于CAPPFramework的CAPP系统的开发与应用

在国家863CIMS目标产品CAPPFramework系统的基础上，研究了面向对象的信息建模技术、信息模型驱动的所见即所得工艺设计技术、工作流技术．并在此基础上进行集成化、智能化计算机辅助工艺设计(CAPP)的应用与开发，实现了工艺设计的自动化，基本达到了在信息集成基础上的工艺设计与工艺信息管理一体化的目的，对企业的CAPP实施具有一定的参考价值．     

多媒体教学手段的不断改进

针对多媒体教学手段存在的问题及如何改进所进行的思考和实践。     

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.     

利用全息扫描技术实现条码识别

根据条码识别装置的特点，利用全息扫描技术设计条形码扫描器及相应的辅助部件，从而使学生对全息照相及扫描技术有进一步的理解，掌握物理实验设计的一般要求。     

信息设备的三大“高空杀手”

 自从人类进入信息时代以来,人类的生存环境也具有浓厚的电磁环境内涵。各种信息技术设备,都存在一个受外界高强度电磁场辐射袭击的问题。雷电、太阳风暴、核电磁脉冲是信息设备的“高空杀手”,它们会干扰信息设备的程序,削弱其性能,甚至使其处于瘫痪状态和烧毁状态。这个问题在上世纪80年代已引起西方发达国家的普遍重视,迅速开展了研究、解决信息技术设备的电磁防护工作。我国近几年对此问题也有足够的认识和重视,对此的研究也进入了高层次。一、雷电雷电是自然界中最强的一种脉冲放电现象,包括雷鸣和电闪。
