scan vt. (-nn-) 1.細(xì)看,細(xì)察;審視。 2.〔口語〕大略一閱;瀏覽。 3.按韻節(jié)念,按句調(diào)讀,標(biāo)出(詩(shī))的格律(指劃分音步)。 4.【電視】掃描;掃掠;搜索。 vi. 1.(詩(shī))符合格律,讀起來抑揚(yáng)頓挫。 2.【無線電】掃描。 This line does not scan. 這一行不合韻律。 n. 1.細(xì)看;細(xì)察。 2.掃視,瀏覽。 3.【電視】掃描;掃掠。 4.眼界;視野。
We have designed the scanning and control system , which includes a pre - amplifier , a pid feedback and scanning - control circuit , high - voltage amplifiers and so on . the function of controlling scan and feedback has been realized 設(shè)計(jì)完成包含有前置放大電路、 pid反饋和掃描控制電路、高壓放大電路等掃描控制電路在內(nèi)的掃描控制系統(tǒng),完成各部分電路性能的測(cè)試及功能調(diào)試,實(shí)現(xiàn)反饋和掃描控制。
Secondly , the implementation of each module of the software is discussed in detail . main content of this part includes the inplementation of the massive image data high - speed transferring from scanner to host by use of a large capacity fifo and a 32bit high - speed pci card , how to control the step motor for precise location of the cis image sensors , the techniques for utilizing the lm9830 to control scanning actions based on the cis ' s characteristics , the real time image data collection , the reconstruction of the image data sampled by the z - shape combined cis sensors , and the parallel and pipeline techniques used in the whole process helping to save time 然后詳細(xì)討論了掃描儀底層驅(qū)動(dòng)軟件中各個(gè)功能模塊所解決的問題和具體實(shí)現(xiàn)方法,具體介紹的內(nèi)容包括:如何利用大容量fifo和高速32位pci接口卡實(shí)現(xiàn)大量圖像數(shù)據(jù)的高速傳輸功能,如何對(duì)步進(jìn)電機(jī)進(jìn)行控制實(shí)現(xiàn)圖像傳感器的精確定位功能,如何針對(duì)cis傳感器的具體特性應(yīng)用lm9830芯片控制cis的掃描動(dòng)作,如何實(shí)時(shí)的采集圖像數(shù)據(jù),如何對(duì)“ z ”型拼接傳感器掃描出的圖像進(jìn)行重構(gòu)以及如何應(yīng)用并行和流水技術(shù)對(duì)整個(gè)掃描過程進(jìn)行控制以提高掃描速度。
As the vital development of the millimeter wave guidance technology , phased array antennas use electrical control scanning beam , which results to faster scanning velocity , more flexible beam control and higher anti - interference ability . thus it can realize target seeking , tracing , guidance at the same time , and can work in the complex and worsening condition 作為毫米波制導(dǎo)技術(shù)的一個(gè)重要發(fā)展方向,相控陣制導(dǎo)技術(shù)中的相控陣天線是采用電控方式掃描波束,掃描速度快、波束控制靈活、抗干擾能力強(qiáng)等,可以同時(shí)完成目標(biāo)搜索、跟蹤、引導(dǎo)等多項(xiàng)功能,能工作在日益復(fù)雜和惡化的工作環(huán)境中。
