The system performed as obtaining the real - time navigation information , adjusting the on - line control parameters , programming flight path , storing and analyzing data , which insured the realization of long distance flight 系统实现了导航参数实时获取、飞行控制参数在线调整、航迹规划与回显、数据存储及分析等功能，并为超视距飞行提供了有利保障。
Asynchronously attempts to send an internet control message protocol icmp echo message with the specified data buffer to the specified computer , and receive a corresponding icmp echo reply message from that computer 试图用指定的数据缓冲区以异步方式将internet控制消息协议( icmp )回显消息发送到指定计算机，并从该计算机接收对应的icmp回显回复消息。
Next , the process of error message packet , echo request and echo reply packet in icmpv6 are analyzed , and then the address resolve and the unreachable detection of neighbor in icmpv6 has been discussed in detail 接着，分析了icmpv6协议中的差错报文处理，回显请求和应答报文的处理过程，还重点分析了地址解析和邻居不可达协议的状态转换机制和实现过程。
In this example , as long as the time - out value requested is less than or equal to the maximum session time - out set at the server on the http endpoint , the server will honor the time - out interval requested by the client and echo the same value 在此示例中，只要所请求的超时值小于或等于http端点处设置的服务器最大会话超时值，服务器将允许客户端请求的超时间隔并在响应中回显相同的值(
An application , named postscript fm screening manager , is also achieved using java language . with the application , postscript file can be displayed . further more , fm screening processing for images in postscript file is realized successfully 采用具有跨平台功能的java语言，编制了postscript文件调频加网管理器，突破postscript文件不能回显、预视的技术禁区，实现了对组版后postscript文件的显示。
User can set radar environment parameter of radar and the carrier . function such as apar clutter and targets data generation , analyzing , storing , viewing , loading and simulator control etc , are provide . object oriented design method enhanced the software modularization and program reuse capability , it ' s also easy to maintenance program source code 该软件通过设置雷达和载机参数，产生相应的回波数据，并进行数据分析和显示；建立雷达模拟器控制平台，发送控制命令，监控模拟器运行状态；完成雷达模拟器与主机的数据交互，数据加载和目标回显。
So that designed the software of auto crash test measure and control system on low cost in short time . the software include auto crash test real - time control child system , magnanimity data high - speed transmission and acquisition child system , date re - show and split child system and data filter child system 从而，以较低的成本，在较短的时间内研制出了满足法规要求的汽车碰撞试验测控系统软件，其中包括汽车碰撞试验实时控制子系统、海量数据高速传输与采集子系统、数据回显与分离处理子系统、数字滤波处理子系统等。
This radar database system fits for china ' s radar network using object - oriented programming design method , recording some important parameters of radar data : the longitude , latitude of radar station , radar type , radar wavelength , radar data format , weather kind ( kind of intensity radar echo , schema of velocity radar , echo shape ) embodying in the radar data , etc . it also records the weather course information embodying in a series of relational radar data : the beginning time of weather course , the ending time of weather course , weather type , etc and the disk information , including recording time , recording contents , recording data number and weather type , etc . above all , this system realizes some basic operational processing : adding , deletion , updating , query of records and also some assistant functions : exportation , data transformation , displaying , backing up of data 该数据库系统采用面向对象程序设计方法，用visualc + + 6 . 0作为应用程序的前端开发工具，用microsoftaccess2000做数据库，不仅实现了对雷达基数据信息的一些基本操作：记录信息添加、删除、修改、查询，还实现了处理、分析雷达基数据所需的一些操作：数据导出，数据格式转换、数据回显(图像方式和动画方式) 、数据压缩、备份等，另外针对日前雷达台站存储雷达数据的现状，还实现了对存储光盘的管理。
