The authors presented a novel synthetic route for the imidazolium functionalized poly（arylene ether ke- tone）s, derived from an engineering plastics polymer, a poly（arylene ether ketone） with 3,3＇,5,5＇- tetramethyl-4,4＇-dihydroxybiphenyl moiety（PAEK-TM）. The preparation of anion exchange membranes comprised converting benzylic methyl groups to bromomethyl groups by a radical reaction, followed by the functionalization of bromomethylated PAEK with alkyl imidazoles, i.e., methyl, butyl or vinyl imidazole. The structure of imidazolium functionalized PAEK was proved by 1H NMR spectra. A class of flexible and tough membranes was then achieved by subsequent film-forming and anion exchange processes. The water uptake and hydroxide conductivities of mem- branes are comparable or superior to those of quaternary ammonium（QA） anion exchange membranes. This work demonstrated a new route for non-QA anion exchange membrane design, avoiding the chloromethylation reagent and oreciselv controlling the degree and location of imidazolium grouos.

A series of novel 1,3,4-thiadiazole derivatives possessing benzisoselenazolone scaffold were designed and synthesized, and their antitumor activities against human cervix adenocarcinoma（HeLa）, human liver cancer cell（SMMC-7721）, human breast cancer cell（MCF-7） and human lung cancer cell（A549） lines were evaluated by CCK-8 assay, The bioassay results demonstrate that most of the tested compounds showed potent antiproliferative effects against various cell lines. Furthermore, compounds 7c, 7e, 7h, 7i and 7k showed significant antiproliferative activities against SMMC-7721 cells, with IC5o values of 2.38, 2.67, 1.35, 2.75 and 2.48 μmol/L, respectively. Com- pounds 7a, 7e, 7j and 71 exhibited highly effective antitumor activities against MCF-7 cells, with IC50 values of 2.89, 2.95, 1.12 and 2.75 μmol/L, respectively. Compound 7j was found to be the most potent compound against A549 cells, with an IC50 value of 1.25 μmol/L. The pharmacological results suggest that the substituents of benzylthio-moiety at position 2 on 1,3,4-thiadiazole are vital for modulating antitumor activities against various cancer cell lines.

Sulfonated poly（ether ether ketone kctone）（SPEEKK） membranes with different degrees of sulfonation（DS） were successfully prepared via electrospinning method. The morphology of the resulted membranes varies from nanospheres to nanofibers with increasing the concentration of SPEEKK. The conductivities of the membranes prepared under the same condition increase with the DS increasing. The spherical morphological membranes with a DS of 1.2 show the highest proton conductivity, 0.55 S/cm, which is much higher than those of the membranes prepared via normal solution evaporation method. The results show that electrospinning is an efficient method to prepare high performance SPEEKK membranes with different morphologies.

今天青少年的生活体验缺失问题,病根在家庭,表现在学校,社会让病情加重。身心发展失衡,学校与家庭教育的现实,使青少年难以获得人格发展所需要的生活体验。成长中的青少年,需要次序与和谐,需要连续生活历程体验。由于成长中的生活缺失,青少年将产生对生活缺失补偿的渴望。生活的过程也是道德学习、品德建构的过程,开发日常生活资源,让青少年体验生活,发展社会适应行为,不仅是社会认同和健全人格的需要,而且也是学校和家庭的教育使命。

家校关系是现代学校制度建设的重要维度。目前的家校互动研究,多关注正面的典型家校合作或负面的家校冲突。附属型家校互动是中国基础教育实践中的一种常态。家校合作中的附属性样态主要表现为应召式家长会、任务领受与攀比式点赞的家校群、交易型义工、作为学校立场的家委会。从文化视角探究,可以认为中国国民心态中的教师本位、家庭本位、学校本位三个观念使得家庭与校方各持立场与利益分歧,在权力博弈与利益权衡中造成家庭对校方的附属格局。为了从当前附属型家校互动中走出来,既需要从中国传统优秀文化中寻找资源(和而不同),也需要从世界教育发展史上寻找资源(儿童立场)。

People's Republic of China is one of the most rapidly developing countries in the world today. There is a great demand on highly actual and accurate spatial information of the whole country, especially of West China which becomes the focus of development of the Chinese government right now and in the next years, but where still not enough topographic maps are available. This raises great challenges to the surveying and mapping community in China. Facing the new challenges the Chinese Academy of Surveying and Mapping (CASM) started its pioneer work early 2002 to explore new techniques and technologies available today toward increasing the map productivity. With import of a CCNS/AEROcontrol system in November 2002, the first DGPS/IMU-based photogrammetric project in China was successfully accomplished jointly by CASM, the Germany-based companies IGI and Techedge. Two photogrammetric blocks of 1:4, 000 and 1:20,000 photo scales, respectively, were flown in Anyang, China. Direct georeferencing and integrated sensor orientation were conducted. Results achieved were proven by using ground checkpoints and compared with those of aerial triangulation. Orthophotos generated based on direct georeferencing shows the high efficiency and quality, and thus proved the promise of the new technology. Furthermore several DGPS/IMU-based photogammetric projects was accomplished one by one and a big project of more than 100, 000 km2 in the Inner Mongolia will be started in August 2003. The paper presents experiences with DGPS/IMU-based photogrammetry in China. Results achieved in concrete projects are shown and evaluated. Politic and technical specialties in China are discussed. Conclusions outline the potential of DGPS/IMU-based photogrammetric production in China.

道德渗透在社会生活的一切领域,道德体验是学校道德教育规律的内在要求,体验具有亲历性、反思性、整合性和不可传授性的特点。关注学生在自己的生活中学习道德,既是学生生命成长的需要,又是寻求支持道德学习的条件。生活中处处有体验,但不是有生活就有体验,回归生活世界,开发体验式道德学习资源,是学校教育的使命所在。如何让学生在自己的生活中学习道德,一是把握“物镜”生活,使学生体验到道德就在身边;二是创设“情境”生活,在情感体验中丰富道德智慧;三是开发“意境”生活,让学生在艺术生活中学会生活。
