THE PASSAGEWAY of THE FLORA MIGRATION ON BOTH SIDES of THE TAIWAN STRAIT IN PLEISTOCENEEPOCH

台湾原为大陆的一部分，以后由于断陷而形成台湾海峡。台湾海峡两岸植物区系关系密切，植物区系相互迁移分布，闽台陆桥是台湾海峡最浅的部分，在更新世冰期，由于海退，陆桥曾4次较长时间露出水面，成为台湾海峡两岸植物区系迁移分布的通道，使得两岸植物的迁移分布得以进行。Taiwan is a part of the mainland of China.The Taiwan strait was Formed as a result of Faulting activity.The Floras have closing relationship in both sides of the Taiwan strait with the mutual migration and distribution。Fujian- Taiwan land bridge is a part of the most shallow in the Taiwan strait.It was revealed on the sea surFace For Four times that is due to the regression in Pleistoeene glacial epoch,thereFore Fujian-Taiwan land bridge turned into passageway of the Flo-ras migration on both sides of the Taiwan strait in Pleistoeene Epoch

凤眼莲对福建龙湖重金属的监测及其评价

通过测定龙湖不同区域的水生植物凤眼莲结果表明,凤眼莲对水体的zn、MO、Pb、Cu等都有较大的吸收富集能力。其根部富集能力略大于其茎叶部位。通过测定表明,龙湖在重金属污染方面基本上处于未污染状态至轻污染状态

Bi and Eu-codoped Y_2O_3 Phosphor Prepared by Microwave Hydrothermal Processing and Its Luminescent Properties

[中文文摘]用微波水热法制备化学计量比为(Y0.94-x,Eu0.06,Bix)2O3(x=0,0.01～0.06)的铋铕共掺杂氧化钇磷光粉。用XRD、SEM、EDS、荧光光谱及HRTEM等进行表征。结果表明:该系统由于铋的加入使(211)晶面的生长受到抑制;在激发波长346 nm时,由于铋的掺入使发光增强;随铋掺杂量的增加,其发光先增强后减弱,并在x=0.03时有最大值;因此该系统可作为320～375 nm的近紫外(如白光LED及高压汞灯)激发用磷光粉。该系统在激发波长为254 nm时,铋的加入使发光强度减弱;因此该系统不适合用于低压汞灯。[英文文摘](Y0.94-x,Eu0.06,Bix)2O3(x = 0,0.01~0.06) phosphor powders were prepared by microwave hydrothermal processing.The powders were characterized by XRD,SEM,EDS,photoluminescence and HRTEM.The growth of the crystal face(211) was restrained,resulting from Bi doping probably.The intensity of the emission spectra was generally enhanced when excited with 346 nm owing to Bi doping.It was raised first and then declined later on,and achieved a maximum when x=0.03,indicating that the phosphor powders can serve in near-UV band of 320~375 nm excitation,for example,forwhite LED and high pressure mercury discharge lamps.The intensity of the emission spectra was generally weakened when excited with 254nm due to Bi doping,suggesting that the phosphor powders as mentioned are not suitable for the low-pressure mercury discharge lamps.福建省重大专项基金(2005HZ02-2)资助项

大專院校男女啦啦隊員內在動機及教練領導與凝聚力之研究

[[abstract]]本研究主要目的，在探討大專院校啦啦隊之領導行為和凝聚力及內在動機之間的關係。受試者分為本校參加啦啦隊學生，女生86名及男生73名的學生。 全部學生159個參加者完成三份問卷︰ 運動領導行為 (LSS) 、團隊凝聚力 (GEQ) 及內在動機量表。資料收集後以獨立t檢定、單因子變異數分析。結果如下︰一、選手知覺的教練領導行為，依序為：訓練與指導、社會支持、正面回饋、民主行為、專制行為。女生顯著高於男生之訓練與指導及正面回饋。二、團隊凝聚力，依序為團體合作、團隊適應、個人親和力和個人吸引力。男生顯著高於女生有較高的團隊凝聚力－個人親和力、個人吸引力、團隊合作、團隊適應。大專啦啦隊選手知覺的內在動機，依序為內在動機、努力、樂趣。四、每週訓練時間為2-3天以上比每週訓練時間1天的選手，有較高的「專制行為」。加強學生的內在動機，對於教練領導與凝聚力和運動表現，有正面的幫助

Phyto-geographical Characteristics of the Evergreen Broad-leaved Forest in Jinguanghu in Tong'an, Xiamen

金光湖植被主要是以木荷、红楠、米槠、青冈等种类为建群种或优势种的次生常绿阔叶林.其种类组成特点说明该地区植被在垂直结构上处于由南亚热带季雨林带向山地常绿阔叶林过渡的分界线上,与邻近地区植物区系在群落结构和组成特征方面的比较结果也说明金光湖植被具有由南亚热带雨林向中亚热带常绿阔叶林过渡的性质,区系比较结果表明金光湖植物区系与相邻地区的植物区系联系密切,且这种联系以热带、亚热带成分为主,具有明显的南亚热带性特点.The evergreen broadleaved forest in Jinguanghu is the largest and best secondly natural vegetation in Xiamen Economic Special Zone. Schima superba, Machilus thunbergii, Castanopsis carlesii, Cyclobalanopsis glauca etc. are its dominant species. Analyses of the community compositions and comparison of community structure and composition with some neighborhood plant communities indicate that Jinguanghu forest is a transitional type from southsubtropical rain forest to midsubtropical evergreen broadleaved forest. Comparative studies of plant flora demonstrate that Jinguanghu flora bear close relationships with its neighbors, and these relationships affirm its transitional and subtropical characteristics correspondingly

激光等离子体中超金属氧化物离子LiZnO~+的产生

By 355 nm laser ablating a composite target prepared from metallic lithium and ZnO in high vaccum, a new hypermetallic oxide LiZnO + ion, which consists of two heterometal atoms and oxygen atom, was observed by using a time of flight mass spectrometer for the first time. The time of flight positive ion mass spectra at different delay time between the accelerated electric field and laser pulse are investigated. It shows that the formation of LiOZn + depends on the delay time, and the hypervalent ion LiOZn + is observed obviously at the delay time from 7.5 to 17.5 μs. These results suggest that the ion molecular reaction between the ablated Li + ions and ZnO in the laser plasma should be responsible for the formation of hypermetallic LiZnO +
