GENETIC DIVERSITY OF THE WILD AND REARED PSEUDOSCIAENA CROCEA

The genetic diversity of both wild and reared Pseudosciaena crocea (Richardson) col-lected from Guan-Jing-Yang in Ningde, China in May 1999 was investigated by random amplified poly-morphic DNA (RAPD) in the present study. The polymorphism and mean difference of the wild popula-tion as revealed by RAPD were 18.9% and 0.0960 respectively, and those of the reared stocks were rel-atively lower, with 16.7% in polymorphism and 0.0747 in mean difference. The genetic distance be-tween the two stocks was 0.0041. From the comprehensive investigation, the main reasons for the loss of genetic diversity were probably overilshing, small number of parents as broodstocks and the debatable arti-ficial ranching. Results from this study also showed that the large yellow croaker populations distributed along Fujian coastal waters including Guan-Jing-Yang still potentially wide genetic variability. It is sug-gested that genetic management and prevention should be scientifically conducted in order to maintain and improve the genetic diversity of the P. crocea population.

离子液体调控溶剂热合成TiO2纳米颗粒及紫外-可见光催化降解性能

以钛酸四丁酯(TEOS)、去离子水为原料,离子液体1-丁基-3-甲基四氟硼酸咪唑盐([Bmim]BF4)为表面活性剂,通过溶剂热法制备了锐钛矿相TiO2纳米颗粒。用X-射线衍射仪(XRD)、扫描电镜(SEM)、紫外-可见吸收光谱仪(UV-Vis)对产物的晶相、形貌和光学性能进行表征。为了评估光催化活性,并以甲基橙水溶液为研究对象,在紫外光照射下分析不同照射时间下光降解效率。结果表明,离子液体、去离子水和钛酸四丁酯的体积比为1.3∶1∶1.3时,反应所得到的TiO2具有较高光催化活性,明显优于未添加离子液体的产品,这一结果可归因于其具有较大的比表面积。     

巧留时政作业 培养思维能力

作业是巩固知识的重要手段,把时政内容当成作业,促使学生关注生活,关心天下事,把时政和地理学习结合起来,事半功倍。在“工业发展”教学时,布置了一道这样的作业题：找工业新闻,并运用工业区位等知识分析该新闻。以下是两则学生完成的作业。     

刍议区域地理教学的情境创设与能力培养——以“澳大利亚”为例

区域地理是自然地理和人文地理的"出发点和归宿",许多自然地理和人文地理的案例都离不开区域这一载体。近几年来,地理高考试题更加注重考查考生的地理学习能力和学科素养,即考生对所学相关课程基础知识、基本技能的掌握程度和综合运用所学知识分析、解决问题的能力。这样,具有基础性、常识性和综合性特征的区域地
