An important processing procedure in which top - priority processing most often results from real - time entries which usually have precedence , through the use of interrupts into lower - priority or background processing 一种重要的处理过程，其中最高优先权处理任务常常由具有优先度的实时任务形成，经过使用中断而进入较低优先权任务或后台处理任务。
Messages which are processed immediately - the message handler doesn t return until the message is complete and asynchronous messages which are processed in the background some time after the message is received - the message handler returns immediately , long before the message is processed 信息（同步信息被立即处理- -直到信息处理完成才返回消息句柄；异步信息收到后将在后台处理一段时间- -而早在信息处理结束前就返回消息句柄） 。
This is a background process through sense - and - respond mechanisms and tools that monitor the health of soa applications , including the all important standards implementations of ws - management and other relevant protocols and standards that implement quality of service for a soa 这是一个通过sense - and - respond机制和监测soa应用程序健康的工具来进行的后台处理过程，包括ws - management和其他相关协议的所有的重要的标准实现以及为soa实现服务质量的标准。
Vecon - con system is triggered by 4 infra - red sensors along the selected lanes with 2 in pairs . false trigger by wind shield and container - type trucks are dalian yaowan phase ii screened out and the system captures and recognizes container numbers , country codes , iso codes automatically in less than 0 . 012 seconds from trigger till image capture . the captured images are transmitted to the tos for processing which enhances efficiency and ensures security while maintaining manpower at the minimal Vecon - con透过四个红外线对射敏应触发器进行触发，两个一组并列于车道上，具备防止集装箱型卡车大型集装箱车拖头等误触发，系统接收到触发信号后，自动抓拍集装箱号码国家代码箱形代码，抓拍的图像会被传送到码头控制系统中心进行后台处理，该系统由触发到抓拍只需不多于0 . 012秒，整个系统大大提高了口岸工作效率，并减低了人力物力的耗用，为港口码头的管理提供了更加高效可靠的处理手段。
By function , hardware is divided to control message input module and communication module , software is divided to show module and background process , which is also subdivided to interpolation module , tool compensation module , nc program coding module , nc process simulation module and system interface function module 硬件结构按功能可分为控制信息的输入模块、通信模块;软件结构按功能可分显示模块和后台处理模块,它们又可细分为插补模块、刀具补偿模块、 nc程序译码模块、数控加工三维仿真模块、仿真系统界面功能模块。
One of the system characteristics in the network security is that it has a set of thorough modes of secure running . it can provide auditing and logging services in the foreground business system , network transports and background processes . it also can associate well with the secure technologies in network layer , link layer and physical layer , so , it can keep the whole security of the integrated business system 该系统在网络安全方面的最大特点是在应用层建立了一套周密的安全运行模式，从前台业务平台、网络传输、后台处理等各个环节进行严格的审核、审计，并能够与许多基于网络层、链路层和物理层的网络安全技术有机地结合起来，从而保证了“综合业务系统”的整体安全性。
The radio frequency receiver supports interface for instrument and base station and air interface for mobile station , and it takes the task of magnifying low noise and down - convert and digital baseband processor filtering and magnifying intermediate frequency to reverse link signal . the digital baseband processor samples the received signal after down - convert radio frequency signal to intermediate frequency signal and processes other processing and supports interfaces to computer , next sends data to computer . the gps receiver supports interface for instrument and gps system , and receives gps system signal , next it demodulates the correlative information and sends out benchmark clock signal we need 射频接收部分主要为仪器和基站、移动台提供空中接口,其主要任务是在反向链路上对接收到的射频调制信号进行低噪声放大、射频下变频变换、中频滤波放大等;数字基带部分为对接收信号变频为中频后进行a / d采样,以及其他的rsp处理并和计算机提供接口,将数据送至计算机进行后台处理、显示等; gps接收机部分为仪器和gps系统提供接口,接收gps系统信号并解调相关信息,输出所需的电文及时钟基准信息等。
The measurement system can automatically control the movement of servo motor and communicate with vna through gpib bus to setup the measurement variable automatically , measure the phase of s parameter . it also can progress the measurement data on the background , display the results by graph data , store them in the data files 系统自动控制伺服电机的运行,对测试探头完成指定的移动定位;通过gpib总线与矢量网络分析仪器通信,自动完成相关测量参数的设置以及s参数的相位测量;对测得的数据进行后台处理,将结果以图形、数据文件的方式显示、保存。
