  • scanning : n. 1. 細看，細察，審視。2. 【電視】掃描，掃掠,搜索。
  1. There are two scanning formats for motion pictures, namely progressive. scanning and interlaced scanning

    摘要運動圖象的掃描方式有2種，即逐行掃描和隔行掃描。
  2. Scanning electron microscopy : after fixed in 2. 5 % glutaraldehyde made up in 0. 1 m phosphate buffer ( ph 7. 2 ), the tissue of testis was post - fixed in 1. 0 % oso4, dehydrated in a progressive ethanol solution, dried and sputter - coated with gold, then observed with kyky - 1000b microscopy and photographed

    掃描電鏡樣品以2 . 5戊二醛（ ph7 . 2 ， 0 . 1m lpbs緩沖液配製）和1鋨酸雙固定，酒精系列脫水，乾燥，真空離子濺射儀噴金， kyky - 1000b型掃描電鏡觀察並拍照。
  3. Current tv system has two types : one is the 60hz based system, the other is the 50hz. the phenomenon of large area flicker is not obvious in the 60hz based system, so the scanning converter uses the way of converting the 60hz and 50hz based interlaced scanning signal to 60hz based progressive scanning signal. employing this way the converter can not only reduce the large area flicker and interline twitter, but erase the raster and display finer and smoother pictures

    現行的電視制式有60hz和50hz系統兩種，在60hz系統里，大面積閃爍不是很明顯，因而本掃描轉換器採用將60hz和50hz的隔行掃描信號統一處理成60hz的逐行掃描信號的方法，這樣可一方面使大面積閃爍和行間閃爍都比較輕，又可消除行結構，重現細膩圖像。
  4. In order to solve the phenomenon of splitting picture which is caused by dismatching of writing and reading speed during converting 50hz based interlaced signal to 60hz based progressive signal, the two - frame memory which can effectively prevent it emerging is used. the scanning converter supplies two communicative ways : rs - 422 and rs - 232

    為了解決50hz隔行信號到60hz逐行信號轉換中由於存儲器寫入、讀出速度不匹配而產生的裂像現象，在本設計中使用了雙幀存儲器，有效的防止了此現象的產生。
  5. The scanning converter comprises five parts : video signal decoding, data reconstruction, progressive video signal encoding, control signal producing and communication

    掃描轉換器包含了電視信號的解碼、解碼后數據的重構、逐行信號編碼、控制信號的產生以及通信五部分。
