篇3:Phytoplankton Community Dynamics in
Phytoplankton Community Dynamics in West Lake After Drawing Water from the Qiantang River
Seventeen phytoplankton dominant species of 218 taxa were found to have contributed to more than 80% of the biomass after analysis of the January, 1955 to December, phytoplankton population at five stations in West Lake after Qiantang River water had been drawn into the lake for a decade. The seasonal fluctuations were obvious; the maximum cell density of 90.91×107-93.58×107 cells/L and biomass of 57.41-58.61 mg/L occurred mainly in summer of 1996,largely as a result of the development of Lyngbya contorta, Merismopedia tenuissima, Oscillatoria limnetica, Spirulina laxissima and Scenedesmus quadricauda, etc. at Stations 2 and 4. At Station 1 located near the inlet for drawing water from the Qiantang River, the species number, cell density, biomass, chlorophyll a concentration and physico-chemical parameters (except for total nitrogen) were obviously greater than those at the other four stations, also greater than the corresponding parameters before the drawing of water from the Qiantang River into the lake.Compared with the results of study on the phytoplankton community in 1980 before the drawing of Qiantang River into the lake, the species number and the total individual density were increased, the dominant species changed somewhat, the biomass was decreased. The water quality was improved (especially at Station 1) after the drawing of river water into the lake.Based on criteria for evaluating trophic status, the biological and chemical indicators such as species composition and dominant species, and other parameters such as annual mean value cell densities (36.06×107-51.27×107 cells/L), biomass (29.03-39.74 mg/L), chl a concentrations (41.29-67.67μg/L), total nitrigen (1.72-2.89 mg/L), total phosphorus (0.12-0.16 mg/L) obtained at Stations 2, 3, 4 and 5, showed that West Lake is still at eutrophic lake.

In the community教学反思
本课时教学内容为关于文具的六个单词。通过本节课的教学,我认为我在教学中有得有失,现反思如下:
优点:
一、开课听歌学唱,给学生营造了一种学习英语的氛围,对于本课学生学习英语有很好的帮助。
二、教师自编的儿歌帮助学习复习了已学知识,给学生后面的表演提供了条件。
三、新知学习,充分地利用各种游戏练习了单词。这样就变把枯燥的单词教学变的有意义起来,让初学英语的学生们学的有兴趣,乐于去学。
四、“猜礼物”给学生说英语创造了条件,让学生有机会展示本节课所学知识,体验了成功的喜悦。同时“STICKER”的`奖励也调动了学生的积极性,使课堂气氛活泼起来。
缺点:
一、活动安排过多,有些环节学生参与面不够广,比如学生与学生问候和猜礼物这个环节,就未让所有的学生都参与进来,每个学生都猜一猜盒子里是什么礼物,这样可以给学生提供更多的说英语的机会,让学生敢于说,大胆说。
二、学生发言不积极,不大胆,平时要注重培养学生积极思维,积极发言的好习惯。
篇5:Study of microbial community structu
Study of microbial community structures in UASB sludge treating municipal wastewater by denaturing gradient gel electrop
The structures of microbial communities in lab-scale upflow anaerobic sludge blanket (UASB) reactors for treating municipal wastewater with different ratios of COD soluble/COD total were studied using denaturing gradient gel electrophoresis (DGGE) of 16S rRNA genes.The microbial structure of the inoculum sludge obtained from a full-scale UASB reactor of treating potato processing wastewater was compared with the structures of sludges collected from three lab-scale UASB reactors after eight months feeding with raw municipal wastewater, with CEPS (chemically enhanced primary sedimentation) pretreated municipal wastewater, and with a synthetic municipal sewage, respectively. Computer-aided numerical analysis of the DGGE fingerprints showed that the bacterial community underwent major changes. The sludges for treating raw and CEPS pretreated wastewater had very similar bacterial and archaeal communities (82%and 96% similarity) but were different from that for treating the synthetic sewage. Hence, despite similar % COD in the particulate form in the synthetic and the real wastewater, the two wastewaters were selected for different microbial communities. Prominent DGGE bands of Bacteria and Archaea were purified and sequenced. The 16S rRNA gene sequences of the dominant archaeal bands found in the inoculum, and UASB sludge fed with raw sewage, CEPS pretreated wastewater, and synthetic sewage were closely associated with Methanosaeta concilii. In the UASB sludge fed with synthetic sewage, another dominant band associated with an uncultured archaeon 39-2 was found together with M. concilii.
