The result would be used in tobacco breeding.4 SRAP technology is used to study the genetic differences among different types of tobacco, including flue-cured tobacco, oriental tobacco, maryland tobacco, burley tobacco, and air/sun cured tobacco, five pairs of primer combinations which can amplify characteristic bands has been screened. Among the five combinations, two of them (SF25*SR2 and SF3*SR26) can distinguish air-cured tobacco including maryland tobacco and Burley tobacco from the other cultivated forms; SF20*SR14 can distinguish sun cured tobacco including oriental tobacco and sun-cured tobacco; SF16*SR14 can distinguish flue-cured tobacco and air-cured tobacco, and SF22*SR14 can distinguish DBJ599 with specisl aroma and the other flue-cured tobacco.5 8 varieties , which represent the different types of tobacco, are divided into 3 groups. I: G-28, II:DBJ599、MD40、By21, III: Basma、Sumsun、XNS、QCT. The cluster analysis result es consistant with experience evatuation.6 Anorthogonal design was used to optimize a ILP-PCR system with 5 factors (DNA, Mg2+, dNTP, primer and Taq polymerase) at 4 levels.The result showed the optimized ILP-PCR system for Nicotiana tabacum L. was: 2uL10×PCRbuffer, 20ng template DNA, Mg2+ 2.0mmol/L, dNTP 150umol/L, primer 0.3umol/L, Taq DNA polymerase 1 U in a total of 20uL reactionsolution.

After pathogenic fungi identified,we found 26 of them can cause cotton leaf spot. The 26 pathogenetic strains were carried out morphological and molecular identification of the firm. The initial identification of the pathogens is through the morphological observation such as the determination of growth, colony morphology, conidia and conidial stalk.

通过对生长量的测定，菌落形态，分生孢子和分生孢子梗等形态学观察进行形态学鉴定；通过PCR扩增真菌核糖体基因转录间隔区序列并测序，并将序列在GenBank上进行同源性比对和构建系统系统发育树等方法进行分子鉴定，鉴定出这26株真菌分属链格孢属、镰孢属、黑孢属、刺盘孢属、匍柄霉属等5个属。

METHODS: After isolated the PBMCs and blood-plasma from adult human peripheral blood by Ficoll-Hypaque centrifugation, the PBMC culture procedure with or without the self-blood -plasma was applied to polarize T cells in vitro , these cells were polarized by PHA(20 mg/L),non-PHA respectively.

用Ficoll-Hypaque梯度离心法分离出正常成人抗凝外周血单个核细胞和血浆，将PBMC置于含或不含有自身血浆环境中，并在植物血凝素(PHA ，2 0mg L)的刺激下进行培养，培养 2 4、48、72h后收获细胞，分别用双色免疫荧光标记，以流式细胞术对CD4+ T细胞表达表面分子CCR3、CCR5进行分析。结果：CD4+ T细胞受自身血浆和PHA刺激后向Th1 Th2两个方向极化，2 4、48、72h后极化率分别达到(13 2 8± 1 5 9)%(12 70± 1 6 5 )%、(17 19± 1 0 3)%(17 5 0± 1 30 )%、(19 49± 2 87)%(18 5 8± 1 49)%；而只有PHA刺激的极化率很低，两组有显著性差异(P 0 1)；Th1∶Th2之比约等于 1。

The concrete steps are: the lactic acid and small-molecule dicarboxylic acid react under the condition with the presence of the catalyst to directly polymerize the carboxyl-terminated lactic acid prepolymer; then the aliphatic polycarbonate diol and the catalyst are added; with the presence of the N2, the reaction is kept for 1 to 10 hours at the temperature of 150 to 200 Celsius system to get the poly lactic acid and polycarbonate copolymer of the low molecular weight; then the reaction is done in the twin-screw extruder at the temperature of 150 to 190 Celsius system to screw out the extension chain; finally the polylactic copolymer of the high molecular weight, toughness and heat resistance is made.

具体步骤是：乳酸和小分子二元酸在催化剂条件下反应直接缩聚合成羧基封端的乳酸预聚物，然后加入脂肪族的聚碳酸酯二元醇和催化剂，在N 2 气氛下，抽真空，在150～200℃温度下，反应1～10小时，得到低分子量聚乳酸/聚碳酸酯共聚物，然后在双螺杆挤出机中在140～190℃下，进行反应挤出扩链，最终得到高分子量的、韧性与耐热性较好的聚乳酸共聚物。
