Research on the Determinants of National Identity of Hong Kong People：An Empirical Analysis on the Sample of Asian Barometer Survey

国家认同是整合社会资源、凝聚社会力量的重要手段，也是保障社会稳定、实现国家长治久安的精神力量。香港特别行政区，由于其特殊的殖民历史、特殊的政治制度和政治地位，当地民众形成了特殊的政治认同和文化认同。近年来，香港民众与内地不断发生冲突事件，方式越来越激烈，影响越来越大，有调查显示，香港民众的国家认同感连年下降，如今已降至历史最低，香港民众正面临着国家认同的危机。造成这种现象的原因是什么？是特殊的政治认同使然还是文化归属的影响？本研究旨在利用亚洲民主动态调查（AsianBarometerSurvey，ABS）2012年的数据，通过比较政治认同和文化认同对香港民众的国家认同的影响差异，以期找出香港民...National identity is of great significance in integrating social resources and promoting social cohesion.

Distribution and Species of Mercury in Water and Sediments from Huangpu River

黄浦江江水的总汞、溶解态汞和颗粒汞含量变化较大,其平均值分别为(0.4±0.44)ng/mL、(0.27±0.42)ng/mL和(0.13±0.10)ng/mL,江水中汞以溶解态汞为主.黄浦江沉积物的总汞含量为70.52ng/g~387.30ng/g,平均汞含量为(204.03±97.41)ng/g.江水和沉积物中汞的沿江分布具有中游高,上游和下游低的特征,西渡—南浦大桥江段汞含量为整个黄浦江最高的江段,汞的分布特征与两岸工农业布局相一致.沉积物总汞与有机质显著相关,沉积物中高汞含量的地点都在高水汞点的下游,与河流的动力沉积特点一致.沉积物中汞以可交换态、腐殖酸结合态、残渣态为主,少量为碳酸盐结合态.从上游到下游,沉积物中可交换态汞具有两端高中间低的特点,而残渣态汞与此相反.在剖面方向上,沉积物中的汞主要集中在残渣态,少量为腐殖酸结合态,可交换态及碳酸盐结合态,随着深度增加残渣态所占比例不规则增加.愈接近长江口,沉积物中的重金属愈容易被重新激活.Levels of total mercury, soluble mercury and particle mercury in water of Huangpu River change greatly, their average values are (0.40.44)ng/mL, (0.270.42)ng/mL, (0.130.10)ng/mL respectively. Mercury in water is mainly in the form of soluble mercury. Average mercury content in sediment of Huangpu River is relative high and up to (204.0397.41)ng/g, with a range of 70.52ng/g387.30ng/g. Mercury content is high in the middle reach of Huangpu River, especially in section of Xidu-Nanpu Bridge, and low in upstream and downstream. Distribution of mercury is hightly related with distribution of industry plants and farming. Locations with high mercury content in sediment are in the downstream of locations with high mercury content in water. Mercury (in sediments) is mainly in the form of residue, exchangeable ions, and humics-bound, seldom is in the form of carbonate-bound. Contrary to residue-bound mercury, exchangeable mercury is low in the middle reach, and high in upstream and downstream. There mainly are residue-bound mercury and little humics-bound mercury, exchangeable mercury, and carbonate-bound mercury in sediment in profile, and the residue-bound mercury increases irregularly with depth. Nearing the Mouth of Yangtze River, mercury in sediment becomes more active.国家自然科学基金资助项目(20077016);; 中国博士后基金项目(2002032148);; 厦门大学行动计划联合资助项目(0660-X01114

Preparation and permeation characteristics of novel PVA/APTEOS hybrid membranes

采用溶胶-凝胶法制备了聚乙烯醇(PVA)/γ-氨丙基三乙氧基硅氧烷(APTEOS)有机/无机杂化膜。用FTIR和XRD对杂化膜进行了表征。测定了膜在乙醇/水溶液中的溶胀行为。考察了杂化膜对85%(质量)的乙醇/水溶液的渗透蒸发分离性能。加入APTEOS降低了PVA的结晶度,有效控制了膜的溶胀,呈现出优良的分离性能。随着APTEOS含量的增加,杂化膜的选择性急剧增加,在5.0%(质量)时达到最大值;同时膜的渗透通量迅速增加。解决了PVA膜trade-off效应。Novel organic-inorganic hybrid membranes were prepared through sol-gel reaction of poly(vinyl alcohol)(PVA)with γ-aminopropyl-triethoxysilane(APTEOS).The resulting membranes were characterized with Fourier transform infrared spectroscopy and wide-angle X-ray diffraction.The swelling degree of PVA and PVA/APTEOS hybrid membranes in water/ethanol mixture was determined.The pervaporation performance was investigated by separation of water/ethanol mixture at 50℃.The effect of APTEOS content on the pervaporation performance was studied.The decrease in swelling degree with increasing APTEOS content was due to the formation of hydrogen and covalent bonds in the membrane matrix.The crystalline region of PVA decreased with increasing APTEOS content.The separation factor for water increased,and then decreased when APTEOS content was more than 5.0%(mass).The hybrid membrane containing 5.0%(mass) APTEOS exhibited the highest separation factor.However the permeation rate increased remarkably with increasing APTEOS content.The trade-off relation of the PVA membrane was solved,and the PVA/APTEOS hybrid membranes showed high pervaporation properties.国家自然科学基金项目(50573063);; 高等学校博士点专项基金(20050384013)~

Permeation and characterization of TiO_2/PVA hybrid membranes

通过纳米TiO2粒子填充改性制备了新型TiO2/PVA杂化膜。红外光谱表明纳米TiO2表面的羟基与聚乙烯醇(PVA)链上的羟基存在较强的氢键作用。扫描电镜显示当TiO2的质量分数低于1.5%时,在PVA中分散均匀。X射线衍射显示纳米TiO2的加入降低了膜的结晶度。通过对含水质量分数低于20%的水/乙醇体系的脱水研究了该杂化膜的渗透性能,考察了TiO2粒子填充量、料液质量分数和温度与膜分离性能之间的关系。渗透通量J随着TiO2、水质量分数和温度的升高而增加,分离因子随着温度和水质量分数的升高而下降,在TiO2质量分数为1.5%时分离因子达到最佳值。40℃下分离质量分数85%的乙醇水溶液,分离因子可达1 590,渗透通量为0.049kg/(m2.h)。Novel nanometer-sized TiO2 filled polyvinyl alcohol(PVA) membranes were prepared.Fourier transform infrared(FTIR) indicates that there is a strong hydrogen-bond interaction between PVA and TiO2.Scanning electron microscope(SEM) shows that TiO2 particles are well distributed in the membrane matrix when TiO2 mass fraction is less than 1.5%.X-ray diffraction(XRD) reveals that the crystallinity of the hybrid membrane is lower than that of the PVA membrane.The permeation properties of the membrane was studied through the dehydration of water/ethanol system,of which water mass fraction is less than 20%,and the effects of TiO2 mass fraction,feed water mass fraction and temperature on the permeation properties of the membrane were investigated.The results show that the permeation flux J increases with increasing TiO2 mass fraction,feed water mass fraction and temperature.Meanwhile,the separation factor α decreases with increasing the feed water mass fraction and temperature.Separation factor arrives at an optimal value when TiO2 mass fraction is 1.5%.The separation factor and permeation flux reach 1 590 and 0.049 kg/(m2·h) respectively for the separation of mass fraction 85% ethanol/water solution at 40 ℃.国家自然科学基金资助项目(50573063);; 教育部新世纪优秀人才支持计划资助项

Preparation and permeation characteristics of PVA/PEG/TEOS hybrid membranes

以聚乙烯醇(PVA)与聚乙二醇(PEG)共混,并与正硅酸乙酯(TEOS)进行交联反应制备杂化膜。FTIR证实杂化溶胶液发生交联反应形成共价键Si—O—C,WXRD观察表明加入TEOS改变了膜结晶度,加入PEG提高了PVA膜对乙醇/水溶液的渗透通量,但分离因子下降,随着TEOS的加入,膜的分离因子提高。在TEOS质量分数为10%时,杂化膜的分离因子达到最大。提高退火温度可以提高膜的分离因子,但通量下降。在100℃下退火12 h的杂化膜对乙醇质量分数为85%的乙醇/水溶液的分离性能最佳。Poly(vinyl alcohol)(PVA) was mixed with poly(ethylene glycol)(PEG) and then cross-linked by tetraethoxysilane (TEOS) to prepare organic-inorganic hybrid membranes.Fourier transform infrared spectroscopy(FTIR) proved that covalent bond Si—O—C was formed in the hybrid membranes.Wide-angle X-ray diffraction(WAXD) was used to observe the effect of TEOS and annealing on crystallinity.The hybrid membranes were tested in separation ethanol/water mixture by pervaporation.The effect of PEG,TEOS content and annealing temperature on the PVA hybrid membrane performance was discussed.The addition of PEG increased the PVA membrane flux,but its selectivity decreased.Water permselectivity increased with the addition of TEOS into the PVA/PEG membrane.The hybrid membrane exhibited the highest water permselectivity when TEOS mass fraction was 10%.Water permselectivity increased by increasing the annealing temperature,but permeation flux decreased at the same time.The hybrid membrane separation performance was best for pervaporation of water/ethanol(85%mass fraction of ethanol) mixture when annealing at 100 ℃ for 12 h.国家自然科学基金资助项目(50573063);; 高等学校博士点专项基金资助项目(20050384013

哌啶阳离子功能化侧链型阴离子交换膜的制备

燃料电池因其能量转化率高、污染小等特点,成为当前的研究热点.然而,作为关键部件的阴离子交换膜仍然存在离子电导率低、耐碱性能差等缺点,这限制了燃料电池的发展.利用威廉姆森成醚反应在聚醚酮主链接枝哌啶鎓盐,成功制备了侧链型阴离子交换膜.设计的哌啶鎓盐通过长柔性亚甲基与主链相连,使膜内形成有利于高效离子传输的微相分离结构,PEKCQA-1.0膜在80℃的电导率高达72.7mS/cm.此外,哌啶阳离子基团离主链较远,减弱了对主链的吸电子作用;同时,环型结构的哌啶阳离子具有一定的空间位阻,减少了OH~-对阳离子基团的攻击,使膜表现出优异的耐碱性能.PEK-CQA-0.8膜在60℃下1mol/L KOH水溶液中浸泡360h后,离子电导率仅下降了8.8%,有望应用于碱性燃料电池.国家自然科学基金面上项目(21376194,21576226
