兴蒙造山带正 （ Nd，t）值花岗岩的成因和大陆地壳生长

“野外地质掌中宝”系统是以WindowsCE为软件平台 ,以掌上电脑为硬件载体 ,适用于野外地质勘探和国土资源调查的便携式工作平台。它包括前端工具软件包、后台伺服处理子系统、通讯子系统以及硬件接口软件等。该系统的开发研究将是以信息高新技术改造传统的野外地质勘探和国土资源调查技术的一次重要实践 ,它的研制成功将为野外地质工作者提供面向2 1世纪的高效、实用、方便的现代化工作平台

THE STUDY AND APPLICATION OF FIELD GEOLOGY PPC SYSTEM

This paper discusses the significance and main work of developing Field Geology PPC System,whose software platform is Windows CE and hardware carrier is PPC.Because of its portable work platform,the Field Geology PPC System is ideal on field geology work.The Field Geology PPC System is composed of front end software tools subsystem,background servo processing subsystem,communication subsystem,and software of hardware interface.Developing this system becomes an important practice of changing the traditional field geology exploration and resource investigative technology by high informational technology.Its successful research will provide an effective and applicable modern platform to field geology workers in 21st century.
