  1. Employing the interlaced scanning, current tv system can compress the frequency band of tv signal effectively and facilitate transmission. but this method reduces the scanning lines of pictures and the frequency of the field. it leads the pictures displayed on tv to have such disadvantages as large area flicker, edge flicker, interlace flicker, raster visibility and creeping line etc. to satisfy people " s vision feeling better, the big - screen, multi - function and high quality tv - set have been made great progress

    現行的廣播電視系統由於採用隔行掃描方式，從而有效地壓縮了電視信號的頻帶，有利於傳輸；但由於這種方式使得圖像的掃描行數少，場頻低，導致了重顯的電視圖像有大面積閃爍、邊緣閃爍、行間閃爍、行結構可見及行爬行等。
  2. Various solutions such as raising response speed of lcd pixels, raising frame frequency, back light blinking, back light scanning, black field insertion and image processing were reviewed

    討論了提高液晶像素的響應速度、提高幀頻、背光源閃爍、背光源掃描、插入黑場和採用圖像處理技術等多種解決方法，並對各種方法進行了分析和評論。
  3. The bzt thin film has good properties in high frequency. the essential principle, technology process and advantages of the ba ( zr0. 3ti0. 7 ) o3 ( bzt ) ferroelectric thin films grown on pt / ti / sio2 / si substrates and quartz substrates by sol - gel process are introduced. the heat - treatment technology was fixed according to the dsc - tg measurement, afm ( atomic force microscope ) and fe - sem ( field emission - scanning electrical microscope )

    我們通過在pt / ti / sio2 / si襯底和石英襯底上制備ba （ zr0 . 3ti0 . 7 ） o3鐵電薄膜，了解了溶膠-凝膠法（ sol - gel ）制備薄膜的基本原理、工藝過程及工藝特點;並對所制得的ba （ zr0 . 3ti0 . 7 ） o3薄膜的前驅體溶液和干凝膠進行了差熱與熱失重（ dsc - tg ）分析，確定了溶膠在熱處理各個階段的反應情況。
