多国文字混合处理系统NHRUSS的文字输入：软件复用技术实例研究

采用软件复用技术，在ＤＯＳ操作系统下，在 ＮＥＣ ＰＣ－９８０１微机上开发 了ＮＨＲＵＳＳ系统。该系统具有中、日、俄、英多国文字和多功能处理等特点。 使用该系统可缩短软件研制周期，提高软件的可靠性。通过ＮＨＲＵＳＳ系统的 实现，说明软件复用技术在软件设计过程中的应用。

Implementation of character input methods in multi-linguistic character mixed processing system NHRUSS - example study of software reusability techniques

NHRUSS system developed in NEC PC-9801 microcomputer is of multi-function and multi-linguistic character, including Chinese, Japan, Russian and English processing system. The system is implemented by means of the software reusability techniques under the system operation of in ternational prevalent DOS. It is the techniques that develop the new software by the existent successful software or component. It is shown that the software development cycle can be shortened and the software reliabilities are improved. The application of software reusability techniques during the software design process through the example study of the implementation of NHRUSS system is described.
