有机酸淋洗液的非抑制型离子色谱法测定有机胺

研究了邻苯二甲酸、苯甲酸和对羟基苯甲酸3种有机酸分别做淋洗液的非抑制型离子色谱法分离测定甲胺、乙胺和正丙胺3种有机胺。3种有机酸做淋洗液均可将3种物质分离开，且分离结果差异不大。在淋洗液浓度相同的条件下，邻苯二甲酸做淋洗液测定的检出限较低，选择3.0mmol/L邻苯二甲酸做淋洗液测得了上述3种物质的检出限和线性范围，并进行了叶面肥试样分析，3种物质的加标回收率在97.0%-98.1%之间。

有机颜料晶体行为和颜色性能的关系——Ⅰ.联苯胺系黄色颜料

合成了系列联苯胺系黄色双偶氮颜料。采用X-射线粉末衍射枝术考察了它们的晶体行为,并关联了其颜色性能。发现C.I.颜料黄14和63为异质同晶体,C.I.颜料黄17存在同质多晶现象。测色结果表明:颜料的晶体行为对颜料的颜色性能具有重大影响。     

用荷瘤裸鼠模型研制抗人肝癌单克隆抗体

1985年Watanabe等报道:用去胸腺载瘤小鼠的脾细胞与小鼠骨髓瘤细胞SP 2/0融合获得抗结肠癌单克隆抗体之后,利用荷瘤裸鼠模型成功研制抗人肿瘤单抗的报道已相继出现:但所获单抗多为IgM,IgG类的单抗得率不高,本工作采用多次手术大部切除瘤块的方法延长荷瘤裸鼠的成活期,获得一株抗人肝癌IgG类单抗、其研制过程和结果报道如下。     

Engineering a mouse balancer chromosome.

Balancer chromosomes are genetic reagents that are used in Drosophila melanogaster for stock maintenance and mutagenesis screens. Despite their utility, balancer chromosomes are rarely used in mice because they are difficult to generate using conventional methods. Here we describe the engineering of a mouse balancer chromosome with the Cre-loxP recombination system. The chromosome features a 24-centiMorgan (cM) inversion between Trp53 (also known as p53) and Wnt3 on mouse chromosome 11 that is recessive lethal and dominantly marked with a K14-Agouti transgene. When allelic to a wild-type chromosome, the inversion suppresses crossing over in the inversion interval, accompanied by elevated recombination in the flanking regions. The inversion functions as a balancer chromosome because it can be used to maintain a lethal mutation in the inversion interval as a self-sustaining trans-heterozygous stock. This strategy can be used to generate similar genetic reagents throughout the mouse genome. Engineering of visibly marked inversions and deficiencies is an important step toward functional analyses of the mouse genome and will facilitate large-scale mutagenesis programs.     

A Novel Multi-Level Trust Algorithm for Mobile Ad Hoc Networks

Firstly, a multilevel trust algorithm for MANET （mobile ad hoe networks） is presented in this paper and the trust level is defined as a three-tuple type in this multilevel trust algorithm. The paper introduces the multilevel trust into MANET, thereby controlling restricted classified information flows among nodes that have different trust levels. Secondly, the infrastructure of MANET that suit to our multi-level trust is presented, Some conclusions are given at lastly.     

小型轴流定桨式水轮机的技术改造

通过对几座多泥沙河流上小型轴流定桨式电站的技术改造，表明，蜗壳式电站中的水润滑橡胶轴承可以容易地改造为稀油润滑轴承；容量匹配不合理的电站可以把1台机组的转轮更换为适宜于小流量发电的低比速转轮；转轮型号不妥的电站应重新设计与水力参数相符的转轮。这些合理、简便、经济的手段，可大幅提高电站的发电量和经济效益。
