分离

Based on the antifungal activity screening of endophytic fungi obtained from Pyrethrum cinerarifolium, the strain of Y2 with higher activity was primarily identified and its active substances were separated.

最后用建立的方法对108份临床样品进行检测并同时进行病毒分离，荧光定量PCR方法检测出73份阳性样品且与病毒分离的符合率为100%，而常规RT-PCR只检测出54份阳性样品，表明本荧光定量RT-PCR法在检测猪瘟病料上具有潜在的应用价值。

Through the synthetically analysis of the historical origins and evolution of the Quebec issue,the author holds that the two referendums in history and the defeat of Parti Quebecois in the provincial cabinet reshuffle in 2003 shows that the anti-separatist is getting domination gradually and it is hard for Quebec to separate from Canada. However,the Q...

作者通过对魁北克问题的历史渊源及在当代的演进综合分析后认为，魁北克历史上的两次全民公投及魁北克人党在2 0 0 3年省政府改组中败北表明，反对分离的主张正在逐步扩大优势，魁北克分离梦难圆；但该问题仍将是影响加拿大联邦构建和英、法裔族际关系的不可忽视的因素。

The purpose of the present work is to conduct the basic and process studies on the resolution of racemate by enzyme-catalyzed reaction.

本研究目的在于采用酶催化反应来分离难以用物理方法分离的外消旋物。

The effects of the content of acetic acid and water in mobile phase on the separation were systematically investigated. The fast enantioseparation of the racemate on monolithic column was successfully realized by stepwise gradient elution.

The effects of racemate initial concentration, volume ratio of surfactant to organic solvent, pH value in internal or external phase, pH gradient from external to internal phase, ligand metallicion and system temperature on the performances of chiral separation were discussed.

摘 要：研究在含有Cu2+和N-n-十二烷基-L-脯氨酸手性配体的乳状液膜体系中手性萃取分离氧氟沙星对映体的效果，以及外消旋体的初始浓度、表面活性剂与有机溶剂的体积配比、内外水相pH值、从外水相到内水相pH值梯度变化以及配位金属离子与体系温度对液膜手性分离性能的影响。

Methods Proteins existed in adult Schistosoma japonicum membrane were extracted by Triton X-100 and purified through reverse-phase high performance liquid chromatography,and the main protein peaks were then collected separately. 125 I-LDL of human plasma as the ligand, through the radioautography and radioligand binding assay, the protein which can bind human serum 125 I-LDL specifically was identified.

自人工感染家兔的肠系膜下静脉取日本血吸虫成虫，用非离子去污剂TritonX 10 0抽提出日本血吸虫成虫表膜蛋白，反相高效液相色谱进行分离纯化后，收集各主要分离蛋白峰，以12 5I标记的人血浆低密度脂蛋白作为放射性配体，经放射性自显影及放射性受体配体结合分析鉴定能与人血浆12 5I LDL特异结合的蛋白。

General approach for noise-free BSS and classical BSS algorithms of real domain data are discussed.

2分析和研究了无噪模型下盲源分离的一般方法和常规实数算法，提出了一类盲源分离的多源复数算法，在计算机上用仿真数据验证了算法的性能。

Results Several amino acid substitutions located in antigenic sites or receptor binding sites were found more in the isolates than the current vaccine virus or the isolates from previous year. Amino acid substitution was found in 3, 140, 142, 144, 145, 158, 159, 189, 192, 193, 198, 204, 225, 226 and 227 positions in the isolates during 2003-2008, more amino acid substitutions took place in antigenic determinant A, B and receptor binding site.

结果 每个流行期分离的毒株都较当年的疫苗株或前一年的毒株出现了位于不同抗原决定簇或者受体结合位点的氨基酸替换。2003-2008年不同流行期分离株在3，140、142、144、145、158、159、189、192、193、198、204，225、226和227位点氨基酸发生了变化，多数的改变发生在抗原决定簇A、B及RBS。

These traits were not observed in both parents. Ratio of white awn to colored awn was 109:343 in a population of 452 plants, suggested it was controlled by epistasis recessiveness in interaction of 2 pair of genes confirmed by χ^2-test.
