GA often uses C or Visual C++ to compile codes, so the program is not only long and cockamamie but also the efficiency is low and the velocity is slow. This paper uses software Matlab powerful calculating ability and many functions to compile programs, then encapsulate and link those programs to run without Matlab environment. At last use Visual C++ friendly alternate function to compile in-out interface.

The author of this paper participated the beginning phase of the whole Yun-Wan freeway geological exploration work. After lucubrating GIS exploitation technique and reading plenty of correlative references the author realized that geological data management is of practical value to engineering project department. Thus, thanks to those profound data accumulated during previous explorations, the author developed a professional and practical GIS system for Yun-Wan freeway—EGIS based on exploitation flat roof - Arc View.

作者参与了云万高速公路的整个地质初勘阶段的工作，在深入学习了GIS开发技术和在查阅大量相关参考文献的基础上，并了解了工程设计部门对地质资料管理的实际需求，将工作中所收集到的大量地质勘察资料作为基础源数据，在ArcView GIS的开发平台上，针对云万高速公路开发出了专业型的实用GIS系统——工程地质资料管理信息系统，系统由Access关系数据库管理系统建立属性数据库，由ArcView GIS软件来实现对空间数据库的管理功能；以软件本身所提供的Avenue语言和程序设计语言Visual Basic 6.0作为系统的开发语言，并对ArcView GIS软件本身的不足方面，进行了二次开发，使系统的功能得到了增强，让系统使用起来更加方便和完善。

This article proposed one kind of improvement algorithm in this foundation, this algorithm has defined a filter balance factor formula, according to this formula, we readjustment filter balance factor value appropriately, through controlsling the LMS filter coefficient's freezing and the restoration, we solute echo puzzle perfectly; In the telephone condition examination algorithm aspect, in view of the busy signal examination algorithm which has has only been able to examine the busy signal, but cannot examine the dial tone, hang the staccato the deficiency, this article improves its algorithm to enable it to apply these aspects, make it can be better used in the actual system application.

本文在此基础上提出了一种改进算法，该算法定义了一个滤波器平衡因子的计算公式，根据此公式，适当调整滤波器平衡因子的阀值，通过控制LMS滤波器系数的冻结和恢复，很好的解决了回声的困扰；在话机状态检测算法方面，本文针对已有的忙音检测算法只能检测忙音，而不能检测拨号音、挂断音的不足之处，研究改进其算法使之能够应用到这些方面，更好的为实际系统的应用服务。

No matter which is true or virtual, the students" needs is the first of all. Based on the present situations and problems of primary English situated teaching in our country. We pose the strategies on the students" curiosities and Finks significant learning theory.
