Constructing cdna expressing library of erythrocytic plasmodium falciparum from hainan : the total rna was obtained by using. triplix kit. a modified oligo ( dt ) primer ( cds ffi pcr primer ) was used in the single - stranded ( ss ) dna synthesis reaction. the ss - dna was reversely transcripted from total rna. double - stranded ( ds ) cdna was amplified by long - distance ( ld ) pcrafter the digestion with proteinase k and sfi i, the cdna with no less than 200bp was collected and purified by glass - milk kitthe library was constructed after the ligation of cdna to tiplex2 phage particle packaged with the packaging extract system in vitro. a high titer and high recombinant ratio of cdna library was constructed
構建惡性瘧原蟲海南株紅內期cdna表達文庫提取紅內期惡性瘧原蟲海南株總rna ，直接以總rna為模板使用cdna文庫構建試劑盒，首先反轉錄合成ss一dna ，再擴增合成ds一dna （ cdna ） ，對擴增產物用蛋白酶k消化及左z丁i酶切，抽提蛋白、去除rna后，用玻璃奶試劑盒純化、回收20obp以上的片斷，經與載體連接再用蛋白包裝物包裝后形成未擴增文庫，最後擴增完成惡性瘧原蟲海南株紅內期cdna表達文庫的構建。 -
Finally, combining the two extraction methods with the two classification methods, the thesis put forward four models of palmprint recognition : k - l + ld model, k - l + nn model, nn + ld model and nn + nn model. the experiments show the accuracy, efficiency and the fault tolerance ability of these models. in terms of their characteristic, we can apply them in various fields
論文把兩種特徵提取方法和兩種分類器設計方法進行結合，提出k - l變換與最小分類器、 k - l變換與bp神經網路分類器、線性神經網路與最小分類器、線性神經網路與bp神經網路分類器四種組合，最後對四種識別方法進行比較，根據它們識別的準確率、效率以及容錯能力對識別結果進行分析，總結出各種方法的優缺點，根據它們的特點，提出在不同方面的應用。 -
