Exploration on enhancing innovation capability of functional information materials in China

The present status and future prospects of functional information materials, mainly focusing on semiconductor microstructural materials, are introduced first in this paper. Then a brief discussion how to enhance the academic level and innovation capability of research and development of functional information materials in China are made. Finally the main problems concerning the studies of materials science and technology are analyzed, and possible measures for promoting its development are proposed.

函数式语言方法在网络交互程序中的应用

网络应用程序中为了保持程序的交互性,服务器端的控制程序如CGI(command gateway interface)程序需要在不同的脚本程序之问切换,这样不可避免的会造成控制信息的丢失.为了避免这些问题,介绍了将函数式程序设计语言的一些方法,如Continuation、CPS(eontinuationpassing style)等,并将它们应用到网络程序设计中,不仅简化了设计过程,也提高了程序的安全性,并可以在更一般的语言中实现.
