Field use and test shows that , ( 1 ) the coupler drive system improves the soft characteristics in the starting and transmission of the pumping unit ; ( 2 ) the new drive system solves the problems of drive slippage and frequent change of rubber belt ; ( 3 ) it provides large transmission rate and enables adjusting the stroke number optionally ; ( 4 ) the system efficiency of the pumping unit can be improved and power consumption can be lowered by using the coupler drive system 现场应用测试表明： ( 1 )耦合器传动系统可改善抽油机启动和传动中的软特性，提高整机和抽油杆的使用寿命； ( 2 )解决了抽油机胶带传动中打滑“丢转”和频繁更换胶带等问题； ( 3 )实现了抽油机大传动比，冲次任意可调，从而满足供液不足油井和稠油注蒸汽生产井的不同需要； ( 4 )可提高抽油机系统效率2 . 24 % ，日耗电量下降39 . 6 % 。
On the one hand , we separate the system into four apartment , basic database , quoting for tenders , the document management and consumer information management , on the other hand , we are going on the logic design for the database in detail according to the requirment . we design the database ' s physical structure and distributing according to client end / server mode . we design the database equitment and the database with microsoft sql server 在应用软件开发上，按照客户端服务器模式设计出数据库的物理结构及分布，在microsoftsqlserver上建立了数据库设备及数据库；在程序编码上，采用面向对象和生命周期法相结合，开发出满足功能设计的应用软件，并在用户的应用测试中不断修改完善，同时给出相应的技术文档；在开发平台的选择上，主要用powerbuilder作为前端开发工具。
To facilitate users of the two sides to choose viewing the web pages of the other side either in traditional chinese or simplified chinese characters , in the first half of 2001 the hksarg installed for testing a software on the " hksar - guangdong link " that automatically converts the presentation of web pages between traditional chinese and simplified chinese characters 为方便粤港两地用户能选择繁体或简体中文版本浏览对方的网页，港方于二零零一年上半年在粤港专线联网上安装了一套繁简体中文网页转换软件，供粤港双方部分用户进行应用测试，测试结果满意。
On the base of technology of modern network management , the author introduced in detail the stages of software procedure in steps of user requirement analysis , outline analysis , detail analysis , system coding , system test etc . and provided the design original code for some important classes 在现代网络管理技术的基础上，作者对eventprocessor子系统的需求分析、概要设计、详细设计、系统编码、应用测试等软件开发过程中的各个阶段都作了详细的介绍，其中对于比较重要的类还给出了类的设计原码。
We design the physical structure and distributing according to client end / server mode in physical design and implement of the database , and design the database equitment ang the database with microsoft sql server , and establish the diagram structure with powerbuilder method ; we design the diagram coding combining object - oriented method with life cycle method . the software is improved by testing in daqing esp company . we also give the technological document 其中数据库物理设计与实施按照客户机/服务器模式设计出数据库结构和分布，在microsoftsqlserver上建立数据库设备及数据库，在powerbuilder中建立表结构，载入调试数据；程序编码采用面向对象和生命周期法结合的方法开发满足功能设计的应用软件，并在用户的应用测试中不断完善，在编码过程中同时给出相应的技术文档。
The system introduces 991 ultra - low frequency pick up , and takes the vibration signal as the simulation input of practical measurement , which makes the s ystem can measure the ultra - low frequency vibration of long , large , tall and flexible structures and the low frequency vibration of engineering and site 系统引入991型超低频拾振器，将其拾取的振动信号作为本系统实际应用测试中模拟输入，使系统可对长大高柔结构的超低频振动和一般工程及场地的低频振动进行测量。
