scan vt. (-nn-) 1.細看,細察;審視。 2.〔口語〕大略一閱;瀏覽。 3.按韻節念,按句調讀,標出(詩)的格律(指劃分音步)。 4.【電視】掃描;掃掠;搜索。 vi. 1.(詩)符合格律,讀起來抑揚頓挫。 2.【無線電】掃描。 This line does not scan. 這一行不合韻律。 n. 1.細看;細察。 2.掃視,瀏覽。 3.【電視】掃描;掃掠。 4.眼界;視野。
The results are presented in the form of snapshots and a - scan plots 模擬結果以波場快照和a掃描曲線形式給出。
Comparison of c - scan of entire sample and the date of local point a - scan collected and processed with the metallorgaphs of sample cross section showed that the method could be used to determine the spot size of resistance spot welding 對接頭焊點的c掃描及對局部點的a掃描信號的采集與分析,經負際焊點橫截面的金相觀察對比,可以較準確確定點焊的焊核直徑。
Studied the cluster and background reduction algorithm and , proposed an enhanced adaptive step average method based on the amplitude of a - scan signal ; 2 . improved the gpr data acquisition and processing software , some utilities have been added such as position wheel control program , data format translation etc . ; 3 . implemented 3d targets imaging using mixed programming of matlab and visual c + + ; 4 本文的主要工作如下: 1 .研究了探地雷達回波信號雜波及背景去除算法,改進了一種基于a - scan信號強度的自適應滑動平均法; 2 .改進并完善了探地雷達數據采集處理軟件,加入了定位輪控制數據采集、數據格式轉換、目標距離測定等程序; 3 .研究了探地雷達目標成像算法,利用動態鏈接庫技術實現了在脫離matlab環境下在visualc + +編寫的程序中調用matlab程序對目標進行三維成像的功能; 4 .參加外場實驗及項目驗收。
