An original survey directed to the end users having interest in dvd recorders was conducted with the intent to incorporate basic functional needs related to " recording , " operability , " and " dubbing " in the new machines . as a result of enforcing these needs , increased high picture quality for long time recording modes improved ; compatibility to record on dual layer dvd - r disc ; easily operable navigation system was installed ; and high - speed dubbing at 16x dvd - r and 6x dvd - rw were realized 并向对dvd刻录机感兴趣的用户提问的方式，解答并说明了新产品对dvd刻录机的“录像” “操作” “拷贝”等基本功能的强化，以达到如下结果：可以长时间保持画面清晰与双层dvd - r兼容安装便于操作的导向系统及实现16xdvd - r和6xdvd - rw的高速拷贝功能。
Computer clocks which synchronized with the observatory s network time service might show incorrect date and time during the period of the fault . users whose applications require recording the accurate date and time should check the date and time recorded . the observatory apologizes for any inconvenience it might have caused to users 于故障期间，使用天文台网络时间服务来校对时钟的电脑可能会出现错误日期或时间，如有关用户的应用程式需记录正确日期和时间，这些用户应检查所记录的日期和时间。
Automobile travel recorder is new a acting high - tech product , but real time record automobile accurately the course of traveling in various state parameters , and through ic card deliver the data of recorder collection systematic personal computer in , analyse through the data for special purpose that analysis software goes to for collection , can reappear automobile the course of traveling in various states 汽车行驶记录仪是新一代高科技产品，可实时、准确地记录汽车行驶过程中的各种状态参数，并通过ic卡将记录仪采集的数据传送到系统微机里，通过专用的分析软件对采集到的数据进行分析，可以再现汽车行驶过程中的各种状态。
Aimed at the short time run of the generator , multi - channel and high precision in aircraft test on ground , based on the idea of multi - channel long time record at locale , then playback and analysis , an aircraft electric multi - channel test system based on vxibus is designed , it is proved to have convenience and high test - precision , and well fulfills the need of multicenter test at locale and implements that multilcenter data can be playback and analysed 摘要针对目前飞机地面电气测试中发电机开机时间短、测试通道多、并且要求测试精度高的要求，按照现场长时间多通道记录，后期回放处理的设计思路，设计了一种基于vxi总线技术的飞机电气多通道测试系统，实践证明该系统使用灵活，测试精度高，很好满足了现场实验多通道数据同时测量的要求，并实现了对多个通道数据后期回放及分析处理。
Through real - time detecting and controlling on the facilities and environment in the central control room , for instance , the setup of the remote control on the air conditioner , the remote control on the real - time recording from 6 - route video cameras and the remote control on the permission of the integrated pan and tilts , the personnel in out access through three main entrances and the informing management for failure identification via phonetic system , the system ensures the safety and effective management in the central control room 通过该系统对机房内的设备及环境进行实时监测与控制，例如：对机房内的空调进行远程开关机设置通过六路视频实时录像，同时允许对一体化球机进行远程控制对3道重要门进行人员出入控制及出入记录将重要事故及故障通过电话语音通知机房管理人员，从而确保机房整体系统的安全性，提高机房管理的效率。
2 . 768 * 576 pixels and 24 bit real time dynamic and static pictures can be captured by a special medical video card . the number and quality of the pictures captured can be controlled by the frame frequency , size of the documents enacted . owing to the image real time compress technology , real time record can be long time , documents transcribed can be re - screened randomly , operation database can be created automatically , normative operation reports can be printed freely 2 、通过一块专有的图像采集卡可以捕获768 * 576象素分辨率的真彩实时动态和静态图像;可通过设定捕捉频率、帧数、文件大小来控制所捕获图像的数量和质量;由于采用运动图像实时压缩技术,可以长时间实时录像,同时能任意回放录制的文件;自动生成手术数据库,能随意打印规范的手术报告单。
" function , the user can record behavior directly in the field by setting the time interval through the audio alarm function for time sampling of behavioral data . if the behavior is recorded on videotape , this program can also match its timing with the timing recorded on the videotape or the vcr counter , and the user can correct data directly or press a special key to perform editing functions corresponding to the vcr , including pause for timing , different playback speeds , and modifying previous records . users can also continue recording data from previously saved data in the 在记录数据功能上，可直接在现场记录，也能够配合时段采样的时间间隔使用闹铃功能，也可以配合所拍摄录影带上的时间(或录影机上显示之时间)做同步记录；修改功能方面，提供直接按键修改或按特殊功能键以配合录影机的特殊功能，包括暂停，不同播放速度和连续多次修改记录；可选择单键即时记录
Familiar automatic recording device for overvoltage can just monitor inner overvoltage , but the device introduced in the paper can real time record lighting impulse overvoltage and inner overvoltage together in 10kv distribution system . with the characteristics of overvoltage in the 10kv distribution network , the principle of realtime recording device for overvoltage is introduced by author , and design and develop applied realtime and automatic recording device for overvoltage first 通常的过电压自动记录装置采样频率不高，采样周期短，大多只能监测内过电压，而本装置研究的目的是能够同时监测雷电过电压和内过电压。作者结合10kv配电系统的过电压特点，提出了10kv配电网过电压实时自动记录装置的基本原理，设计并研制成功了实时监测大气过电压和内过电压的监测装置。
