数字化条件下航天产品的工艺文件在表现形式、组织架构等方面与传统工艺文件有着本质的区别,导致现有工艺文件管理标准不足以支撑数字化工艺设计.从航天行业标准《航天产品工艺文件管理制度》标准族中提炼工艺文件管理要素,并以管理要素为主线全面分析《航天产品工艺文件管理制度》系列标准在数字化条件下的适用性,在此基础上提出数字化条件下工艺文件管理要求建议,为以后航天产品数字化工艺文件标准制定提供参考.

本文介绍了以知识化思路开展通用产品货架化管理的概念和思路,详细阐述了通用产品目录管理,货架产品组批生产与选用配套管理流程、货架产品组批生产与选用配套管理平台的设计及应用,货架组批投产模式的实施是实现科研生产模式转型的基础.

The XML-based structured data organization and management technology is proposed for the communication protocol of ground telemetry software.The technology can accommodate the communication protocol changes by modifying the communication protocol text file based on the XML with no modification on the program.It can reduce the maintenance costs of modifying the communication protocol,and improve the program safety.

Aiming at the features of raw data protecting, large quantity data storage and the trend of telecommuting in 3D modeling and visualization, comparing B/S architecture with C/S, the paper presents a B/S-based approach to 3D geoscience modeling system, which consists of client, Web server, application server, and database server. In order to ensure real-time display and interactive of the images, the article proposes the establishment of double buffer, display list and dynamic compression ratio.
