摘 要 目的：探讨我省不同地区致乏库蚊对化学杀虫剂的抗药性现状。方法：采用浸渍法测定致乏库蚊幼虫的LC50。结果：不同地区致乏库蚊对溴氰菊酯均达到相当高的抗性水平；对敌敌畏和三氯杀虫酯的抗药性明显；对仲丁威的抗药性尚不明显。

Afterintroduction of basic electroluminescent theory of polymers and discussion of the studysituation of electroluminescent polymers and polyphenylene vinylene particularly, therelationship among structure, solubility and electroluminescent properties was studiedIn this paper, polyether-type PPV, polythioether-type PPV, and PPV containingoxadizole, biphenylene, or saturated aliphatic unit were synthesized, the monomers andpolymers were characterized as well.

在讨论了电致发光聚合物的基本发光原理并深入地分析了国内外有机电致发光聚合物尤其是聚苯撑乙烯的研究现状与发展趋势的基础上，论文着重研究了PPV衍生物的结构与它的可溶性以及电致发光特性的关系。

At present, the investigation about this aspect is concentrate on the pure inorganic cathodal electrochromic materials like WO3 and organic electrochromic materials like Prussian blue and Polyaniline.

关于这方面的研究却主要集中在以WO_3为代表的一元无机阴极电致变色材料和普鲁士兰、聚苯胺为代表的有机电致变色材料上，对多元的电致变色材料的研究较少。

The results showed: for the toxicity of two kinds of pollutants, the Cd(superscript 2+) is more poisonous that the Pd(superscript 2+). For the sensitivity to the pollutants, the P. caudatum, C cathayensi and D. japonica increase evidently in turn. The statistical analyses indicated that the single and combined toxicity effects both increase with the exposed time extended, especially for the combined toxicity (P.05), showing a marked time-effect relation. As for the single effect, ii increase prominently with Pb(superscript 2+) and Cd(superscript 2+) concentrations (P.05); But in the case of binary effect, the results showed obviously a time-effect (P.01) as well as a concentraction-effect relations.

结果表明：在同等条件下，Cd(上标 2+)对三者的致毒效应都明显强于Pb(上标 2+)；3种动物中，草履虫最敏感，而圆田螺耐受能力最强；随单一毒物浓度的增大以及暴露时间的延长，两者的致毒效应都显著增大，表现出明显的浓度－效应和时间－效应关系；二者复合作用时，对3种动物的致毒效应主要表现为与二组分的浓度比例有关。

In managing the disasters, scientific field pays attention to the disaster factors, eg. Some countries have improved their ability of monitoring and predicting natural disaster factors by applying geographic information system. While the civil administration organs show great concern for damageableness of the community they govern.

在灾害管理工作中，科学界关注的是致灾因子，如一些国家应用地理信息系统，提高了对自然致灾因子监测和预测能力；而民政部门更关注的是所辖社区的易损性，通过建立区域内灾害信息数据库，可根据易损性特征，对各种致灾因子采取不同的防御措施。

Methods Peripheral blood mononuclear cells from healthy donors were induced to become dendric cells and CIK, using tumor antigen extracted from gastric cancer SGC7901 cells to sensitize DC, antigenpulsed dendritic cells were cocultured with CIK to generate CIK induced by gastric cancer antigenpulsed DC.

从正常人外周血单个核细胞诱导DC、CIK细胞，用胃癌细胞SGC7901抗原致敏DC。致敏DC与CIK共培养，制备经胃癌抗原致敏的DC诱导CIK细胞。

The results show that complexing agent greatly effects on film's density. For the double complexing agents solution system based on citric acid, the solution with lactic acid and citric acid produced most compact film with lowest porosity; and for the double complexing agents solution system based on butane diacid, the solution with butane diacid and malic acid made most compact film with lowest porosity.

研究结果表明：络合剂对镀层的致密度影响显著，对于以柠檬酸为基的双络合剂体系镀液来讲，乳酸-柠檬酸双络合剂体系镀液获得的镀层致密度最好，具有最低的气孔率；而对于以丁二酸为基的双络合剂体系镀液来讲，丁二酸-苹果酸双络合剂体系镀液获得的镀层致密度最好，具有最低的气孔率。
