利用RAPD标记鉴定芥菜(Brasica juncea Cos.)品种(英文)

从６０种１０ｂｐ随机引物中筛选出７种引物,对８个芥菜变种的１６个品种（每个变种有２个品种）进行了随机扩增多态性ＤＮＡ（ＲＡＰＤ）鉴定,能快速、灵敏、较为简便获得了１６个芥菜品种的基因组ＤＮＡ指纹图谱．结果表明,不同引物在１６个品种上都有其特征ＤＮＡ带,一般只有１条,少数有２条．在同１个变种的２个品种之间存在着丰富的ＲＡＰＤ标记,通过比较２个品种各自独具的ＲＡＰＤ标记,就可明确地将２个品种区分．在所用的７种引物中,没有１种能同时将８对芥菜品种全部区分开,但用２种或２种以上的引物就完全可以将８对芥菜品种全部区分开．

LIQUID DYES''CHARACTERISTICS IN DYEING WASTE PAPER PULP AND THEIR APPLICATION

In this paper, some liquid dyes were used to dye the waste paper pulp (OCC pulp and waste cement sack paper pulp), and their dyeing characteristics were analyzed, The liquid dyes include liquid basic yellow, liquid basic blue, liquid basic red, liquid basic orange, liquid basic brown and liquid direct black. We found that, each dye had its own dyeing characteristic while dyeing the waste paper pulp.Generally different types of liquid dyes were combined to dye the waste paper pulp, which the adding process must be noticed. We also observed that a black pigment could be applied together with said liquid dyes to dye or adjust the color of the bottom sheet for the fireproof board. We could also achieve the same dyeing result through different combinations of different dyes.     

废气再循环阿特金森汽油机经济性优化算法

基于一维整机模型在3 000r·min-1部分负荷工况下对Atkinson汽油机性能进行仿真分析.结果表明,在保持节气门位置、空燃比与点火提前角不变的情况下,随着废气再循环率提升或随着LIVC(late intake valve closing)增大,发动机的油耗均呈现增大趋势.为进一步优化Atkinson发动机燃油经济性,在节气门全开条件下搭建了GT-power与MATLAB联合仿真模型,通过改进的遗传算法,对废气再循环率、进气门晚关角、点火提前角、空燃比等参数进行优化迭代,并对历代种群进行了模糊聚类分析,得出了不同负荷工况点的油耗最优值及对应的控制参数.
