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)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(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。
The results are presented in the form of snapshots and a - scan plots 模擬結(jié)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(diǎn)的c掃描及對局部點(diǎn)的a掃描信號(hào)的采集與分析,經(jīng)負(fù)際焊點(diǎn)橫截面的金相觀察對比,可以較準(zhǔn)確確定點(diǎn)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(dá)回波信號(hào)雜波及背景去除算法,改進(jìn)了一種基于a - scan信號(hào)強(qiáng)度的自適應(yīng)滑動(dòng)平均法; 2 .改進(jìn)并完善了探地雷達(dá)數(shù)據(jù)采集處理軟件,加入了定位輪控制數(shù)據(jù)采集、數(shù)據(jù)格式轉(zhuǎn)換、目標(biāo)距離測定等程序; 3 .研究了探地雷達(dá)目標(biāo)成像算法,利用動(dòng)態(tài)鏈接庫技術(shù)實(shí)現(xiàn)了在脫離matlab環(huán)境下在visualc + +編寫的程序中調(diào)用matlab程序?qū)δ繕?biāo)進(jìn)行三維成像的功能; 4 .參加外場實(shí)驗(yàn)及項(xiàng)目驗(yàn)收。
