Since a lot of important files and other valuable information stored as text style are transmitted on the network , people can use multimedia treatment software to edit and modify text data conveniently if no protective measures for texts are taken . it is obvious that the research on the copyright protection of texts is no time to delay 由于人们很多重要的思想以及其它有价值的信息都是以文本的方式存储并在网上传输,如果不对文本采取任何保护措施,文本的内容很容易被非法编辑和修改,可见研究文本的版权保护问题无疑迫在眉睫。
In conclusion , it is primarily described that the expectable social and economical benefits of this mis are great , and the design can be fulfilled smoothly . the difficulty of this thesis is : not only think about the coordination each other synthetically on workers , equipments , technologies , data and user ' s priorities , different project and different continuation day , but also must ensure that it is agility , controllable and safe when the data be transmitted on internet or intranet 本管理信息系统强调是针对无形的数据信息产品( gis等海量数据)的生产管理信息系统，不是单纯的统计计算，还要实施严密的控制，除需要综合考虑人员、设备、技能技术、权限、工程、工期在计划调度统计方面的协调性外，还需要强调海量数据信息产品的原始数据、半成品、成品在网络上流动的灵活性、可控制性和安全性。
Based on simulations , it is proved that ( 1 ) friday can give tcp protection from the aggressiveness of high - rate udp flows to some extent ; ( 2 ) friday is effective in the case of one - way tcp transmitting ftp ; ( 3 ) in the case of transmitting on - off pareto traffic and two - way tcp with higher burstness , friday is able to provide a higher fairness than lqd ( longest queue drop ) with the same scheduling algorithm ; ( 4 ) in the case of multiple bottleneck links , the fairness of friday is still better than lqd and red 用仿真实验证明，当存在高速udp流时， friday对tcp流具有一定的保护作用。 friday不仅对传输ftp业务的单向tcp有效、而且对传输on offpareto业务的tcp和具有更大突发性的双向tcp也可以提供比采用同样调度算法的lqd （最长队列丢弃）算法更好的公平性；当存在多条瓶颈链路时， friday的公平性仍然优于lqd和red 。
Ellipsometry based on polarized transformation , beams of light reflecting and transmitting on the thin films , is the method which inverse ellipsometric parameters processed by computers to obtain various of optic parameters of measured thin films . although a few researchers have discussed ellipsometric parameters of gratings on theory and experiment 椭偏测量技术是利用光束在薄膜上反射和透射时出现的偏振变化，通过椭偏仪测量其椭偏参数的变化，用计算机处理由测量得到的椭偏参数从而反演得到待测薄膜的各种光学参数。
The core component of data acquiring terminal on the spot is dsp . dsp can not only complete the task of monitoring and management , but also expand the function of the system in digital filtering and data compressing . the system uses embedded modem chip with low price to modulated the data which are transmitted on the pstn 现场数据采集及发送系统的核心是dsp 。 dsp不但可以完成对现场系统的监控管理，还可以进一步扩展系统数字滤波、数据压缩等方面的功能。系统选用低价格的嵌入式modem芯片完成数据在公众电话网上的调制传输。
