模擬結果表明，該方法重建的解碼圖像整體感好，無塊匹配搜索法的塊輪廓，而編碼速度和塊對數搜索法相當。 -
Transfection of antisense pcdna3 - doc - 1r plasmid and testing influence on cell growth we have transfected sense and antisense pcdna3 - doc - 1r plasmids into mouse nih3t3 cells respectively, then transplanted cells which were in logarithm growth phase into 24 orifice plates, sampled one time per 24hs, every time chosen three orifices " cells
另將pcmv一cdkz 、 pflag一doc一ir質粒轉染hela細胞中，通過免疫熒光顯微技術，尋找doc一ir和cdkz兩種蛋白細胞內原位結合的證據。實驗結果1 .小鼠doc一ir基因鑒定小鼠doc一1redna編碼序列長為92obp ， orf編碼127個氨基酸。 -
The elliptic curve digital signature algorithm ( ecdsa ) is the elliptic curve analogue of the digital signature algorithm ( dsa ). it was accepted in 1999 as an ansi standard, and was accepted in 2000 as ieee and nist standards. unlike the ordinary discrete logarithm problem and the integer factorization problem, no subexponential - time is known for the elliptic curve discrete logarithm problem. for this reason, the strength - per - key - bit is substantially greater in an algorithm that uses elliptic curves
橢圓曲線數字簽名演算法（ ecdsa ）是數字簽名演算法（ dsa ）的橢圓曲線對等。它先後成為ansi ， ieee ， nist和iso的標準，而且其它的一些組織正在考慮成為其標準。不象普通的離散對數問題和因數分解問題，橢圓曲線離散對數問題沒有已知的亞指數演算法，所以使用橢圓曲線的演算法在密鑰的位強度是足夠高的。 -
