  1. To overcome the disadvantages of the linear calibration methods such as mlr and pls, least - squares support vector machine ( ls - svm ) is introduced to nir quantitative calibration in this thesis. for a set of diesel cetane number ( cn ) samples, the ls - svm model obtains the best performance in the cn prediction, compared with the mlr and pls model

    為克服mlr與pls等線性校方法的局限性,本文將最小二乘支持向量機( ls - svm )演算法用於近紅外光譜的定量校,並以批柴油值樣品數據為例對以上方法進行了比較。
  2. Rufifacies, peak 16 ( unknown ) and 25 ( 11 -, 13 -, 15 - methyl - hentriacontane ) for b. peregrina and peak 3 ( unknown ), 4 ( tricosene ) and 23 ( unknown ) for p. crassipalpis. additionally, the models were developed respectively to determine the larval age of different flies accurately. 2 temperature effects of time - associated characteristic in cuticular hydrocarbons of aldrichina grahami larva highly significant correlation were observed between the relative abundance of some larval cuticular hydrocarbons associated with gas chromatographic peaks and the chronological age of al

    2溫度對巨尾阿麗蠅幼蟲表皮碳氫化合物組成時間特徵的影響及日齡推斷模型的建立巨尾阿麗蠅幼蟲表皮碳氫化合物組份色譜峰,即p30 (二五烯a ) 、 p33 () 、 p48 (二七烯a ) 、 p49 (二七烯b )和p79 ()含量與幼蟲日齡呈極顯著相關,且在不同恆溫( 16 、 20 、 24和28 )下的變化趨勢基本致。
  3. A novel aqueous two - phase system can be formed by the mixtures of a polymer and cationicanionic surfactants. such a system can be used as a partitioning system of proteins. in this work, we investigated the formation, phase behavior and protein partitioning in aqueous two - phase systems formed by dodecyltriethylammonium bromide / sodium dodecylsulfate / peg and dodecyltriethylammonium bromide / sodium dodecylsulfate / dextran. the ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated. it was shown that the surfactants and polymers are enriched in different phases of aqueous two - phase systems. phase separation are promoted by increasing temperature and adding inorganic salts. different proteins are partitioned in different phases. the selectivity of protein partitioning is increased by adding ligands with affinity

    報道了由負離子表面活性劑與高聚物混合溶液形成的種可用於蛋白質的分離及分析的新型雙水相萃取體系.研究了負離子表面活性劑(溴化基三乙銨/基硫酸鈉)分別與葡聚糖和聚乙二醇混合雙水相體系的形成規律、相行為及牛血清蛋白和溶菌酶在雙水相體系中的分配.通過在高聚物分子中接上親和配基,研究蛋白質在雙水相體系中的親和分配.結果表明,在該體系中,表面活性劑與高聚物分別富集於不同相中.升高溫度及加入無機鹽均可促進雙水相體系的形成,不同蛋白質可分配于不同的相中.親和配基的引入極大地增強了蛋白質分配的選擇性
  4. Choose an optimum condition on the basis of that to go on an amplification experiment whose product become the raw and processed materials with which the influence between the adding of dbs a as the second dopant and the conductivity of cp is studied

    根據交試驗結果,選取個最優條件並進行放大實驗。以該試驗產品為原料,研究了基苯磺酸二次摻雜對絲炭/聚苯胺導電材料導電性能的影響。
