Ajax實(shí)現(xiàn)的WEB下載,由于OA系統(tǒng)是基于WEB方式的，如果只判斷用戶是否點(diǎn)擊“下載文件”，就來判斷用戶是否成功下載了文件。這種方式很顯然行不通，怎么辦呢？我想到的就是用一控件，然后用回調(diào)事件來處理數(shù)據(jù)庫方面的問題(下載記錄問題) 有興趣的朋友可在 http://www.interdrp.com/ 下載分銷系統(tǒng) 用測試帳號進(jìn)系統(tǒng)后,點(diǎn)測試程序,再點(diǎn)WEB下載 可以看見效果 https://www.interdrp.com/software/ReYoWebDownLoad.zip(點(diǎn)擊下載此控件) API說明 ReYoWebDL.copyright="銳洋軟件擁有版權(quán) http://www.interdrp.com/" //必須 ReYoWebDL.url="http://dl.baofeng.com/storm3/Storm2009-0504-1.exe" //下載文件的路徑 ReYoWebDL.path ="" //保存文件地址 ReYoWebDL.ReYoStartDownload() //下載動(dòng)作 ReYoWebDL.ReYoStopDownload() //停止下載 ReYoWebDL.size //下載文件大小 ReYoWebDL.bytes//已下載大小 ReYoWebDL.speed //下載速度 KB/S ReYoWebDL.done //下載是否完成 ReYoWebDL.cancle=true //是否取消下載 ReYoWebDL.urlsource //下載文件名 ReYoWebDL.percent //下載百分比

This work titled A Digital Phase Locked Loop based Signal and Symbol Recovery System for Wireless Channel is intended to serve as a document covering funda- mental concepts and application details related to the design of digital phase locked loop (DPLL) and its importance in wireless communication. It documents some of the work done during the last few years covering rudimentary design issues, complex implementations, and fixing configuration for a range of wireless propa- gation conditions.

This book is an outgrowth of the pioneering development work done by InterDigital Com- munication Corporation in 3rd Generation TDD WCDMA Technology. Many engineers and managers were involved in this development, which spanned a wide range of tech- nology areas, including system architecture, radio interface, radio modem design, radio resource management and hardware/software implementation. In addition, TDD WCDMA technology had many direct and indirect contributors across the globe in the context of the development of the 3GPP TDD WCDMA Standard.

Striking developments have taken place since 1980 in feedback control theory. The subject has be- come both more rigorous and more applicable. The rigor is not for its own sake, but rather that even in an engineering discipline rigor can lead to clarity and to methodical solutions to problems. The applicability is a consequence both of new problem formulations and new mathematical solutions to these problems. Moreover, computers and software have changed the way engineering design is done. These developments suggest a fresh presentation of the subject, one that exploits these new developments while emphasizing their connection with classical control.

German universities and scientists have repeatedly set the intermational standard in drive technology. Identification and active compensation of natural frequencies in oscillatory mechanics, status controls with monitoring structures incorporating acceleration sensors, adaptive compensation of measurement system deficiencies, self-adjusting detent torque compensation… everything invented with only a single aim in mind: to continue improv-ing the motion control, dynamics, precision and processing speed of your machines. For the industrial applicabability of this technology scientific publications in proceedings and laboratory test rigs are not enough. These features consequenty need to be converted into cost-efficient and easily manageable products. That 's exactly what we have done.So in future, if you should need more than today ' smarket can offer you, now everything isgoing to be alright. With our new high-performance ServoOne drive series you will experi-ence
