According to the characteristic of ieee 1394 with wide bandwidth, common and real - time, the author put forward ieee 13 94 should be applied into real - time digital video transfer in optics - electronics theodolite. before engineering realization, carried out a video image transfer test on three types of digital video tape recorders and camera with ieee 1394 interface. we found that digital videos without compression transfered under ieee 1394 standard ( transfer from 4. 5m to 100m ), compared with analog videos, have no geometric distortion, and have better luminance, contrast, definition
作為工程實現前的實驗研究，對三類具有ieee1394介面的數字錄像機和攝像機進行了視頻圖像傳輸實驗，發現無壓縮格式的按ieee1394標準傳輸的數字視頻圖像（傳輸距離從4 . 5米到100米之間） ，較原始模擬視頻圖像在幾何位置信息上沒有衰變，而在亮度、對比度、邊緣清晰度這些方面有明顯的優勢；但是按dvcam壓縮格式（常見于sony公司的系列產品，是5 ： 1的dct幀內壓縮）壓縮的數字視頻圖像，較原始模擬參照圖像有明顯的幾何畸變。This paper develops iterative formula of sine and cosine function in document [ 40 ], and presents new pixel - level algorithms for generating archimedes and involute curves which are widely used in engineering
本文推廣了文獻[ 40 ]中正弦、餘弦函數的遞推公式，對工程繪圖中常用的阿基米德曲線和漸開線設計了新的逐點生成演算法。In this work, un - doped and nano sic doped mgb2 / fe tapes and wires were fabricated by the powder in tube ( pit ) technique, and the short samples were synthesized through two different routes of the traditional vacuum sintering and the sparking plasma sintering ( sps ). the sintering parameters were optimized in both sintering methods
本文採用粉末套管法（ powderintube ）原位（ in - situ ）制備了非摻雜和納米sic摻雜的mgb2 / fe超導線帶材，分別採用常規真空燒結和放電等離子燒結（ sps ）兩種方式合成mgb2超導相，優化了燒結工藝參數。With frequencies arising, close resonators have limitations on lowing quality factor 、 reducing the size of resonator and modes denseness etc. within microwave frequencies, electromagnetism open resonator technologies are widely used in electrical dielectric parameter measurement of low loss dielectric material
隨著頻率的升高，封閉的諧振腔存在品質因數降低、腔體尺寸減小、模式密集等局限性，所以在毫米波頻段，測量低損耗材料電介質參數最常採用的是電磁開腔技術。分享友人
