1短纤维和织物增强混凝土薄板试验研究显示文摘研究了乱向短纤维、织物和预应力织物增强混凝土薄板的四点弯曲性能。混凝土基体采用了德国快硬硅酸盐水泥、中国硫铝酸盐水泥;短纤维用E玻璃纤维和耐碱玻璃纤维;织物采用耐碱玻璃纤维织物和碳纤维织物。试验表明,耐碱玻璃纤维织物较短纤维增强混凝土薄板的增强效率高,预应力碳纤维织物较非预应力碳纤维织物则有更高的增强效率。荀勇 孙伟 Reinhardt H.W. Krueger M. 2005土木工程学报2005,38,11:37

4Fiber Migration and Distribution of Twist at Different Radial Positions of Rotor Yarn-by Hi-Scope Video Microscope System显示文摘This paper describes systematic measurement of fiber migration and distribution pattern of twist at different radial positions of rotor spun yarn mixed tracer fiber by Hi-Scope Video Microscope System. The positions of tracer fibers were measured in three dimensions accurately, and the migration index and the twist distribution at different radial positions of rotor yarn were calculated and analyzed. This research result serves to provide useful references for further study on the structural mechanics of rotor spun yarn.王善元 CHEUNG H.W. 张宏伟 LO M.T. 卢明德 2002Journal of Donghua University(English Edition)2002,19,3:5

8法洛四联症患者肺动脉瓣置换后自体移植物功能的长期随访显示文摘Aims: To analyse the long-term outcomes after pulmonary valve replacement(PVR) in patients with a previous correction for tetralogy of Fallot. Methods and results: In a retrospective study, 158 adult patients with a diagnosis of tetralogy of Fallot, who had undergone a PVR after initial total correction in childhood, were identified from the CONCOR(CONgenital CORvitia) registry. All patients underwent 175 PVRs between June 1986 and June 2005. To analyse the predictors for homograft dysfunction and adverse events(death, reoperations, balloon angioplasty), Cox-regression analysis was performed. Overall freedom from significant homograft dysfunction was 66%after 5 years and 47%after 10 years. We could not identify predictors for combined homograft dysfunction. Event-free survival was 78%at 10 years and 68%at 15 years after PVR. Both early significant pulmonary regurgitation(PR)(HR 6.8, P=0.017) and pulmonary stenosis(PS)(HR 4.0, P=0.037) after surgery were associated with adverse events. When analysing direct post-operative PR or PS,we observed that in patients with severe, pre-operative PR, right ventricular aneurysm/patch resection resulted in a lower post-operative PR(mean difference grade 0.38±0.14, P=0.01). Less significant post-operative PS was associated with a higher diameter of the homograft(HR 0.37, P=0.006). Conclusion: While 47%of the patients in our study were free from homograft dysfunction at 10 years after PVR, event-free survival after PVR remained fairly good(78%). Significant residual lesions directly after surgery influenced event-free survival. A smaller diameter of the pulmonary homograft and severe pre-surgical PR were related to early homograft dysfunction after surgery.Oosterhof T. Meijboom F.J. Vliegen H.W. B.J.M.

11THE LIGHT INDUCED CHANGE IN TRANSIENT PHOTOCONDUC-TIVITY OF POLYMORPHOUS SILICON FILMS显示文摘The decays of transient photoconductivity and their light-induced changes of polymorphous silicon (pm-Si:H) films were investigated. The decays can be fit fairly well by a sum of two exponential decay functions, which indicates that there are two kinds of traps contributing to the process. The light-induced changes of the concentration and energy level of the traps were estimated. The results show that the light-induced changes in trap energy position Et, trap concentration Nt as well as photoconductivity are markedly less for pm-Si:H than that for a-Si:H.S.B. Zhang, G.L.

12古代奥林匹克运动会史话显示文摘第一章古代和现代一八七○年九月一日,也就是在拿破仑三世向普鲁士宣战后不到八个星期的日子,法国在色当的战役中遭到了惨败。九月四日法兰西宣布废除帝制,成立资产阶级共和国,十天后,巴黎宣布了投降,紧接着,普鲁士又侵占了法国的阿尔萨斯和洛林两地区。这一系列的失败给法国带来了极度的和长期的黑暗,但是,这也给现代奥运会的产生提供了温床。据说拿破仑一世的代表队在伊顿的一些运动场上输掉了那些决定性的比赛。这种不幸情况的产生是由于当时在法兰西的公立学校中,教学大纲的制定过分强调了智育而忽视了体育,同时学校中没有体育场,学生几乎没有参加体育锻炼和比赛的机会。正因为如此,男爵顾拜旦感到十分担忧。在色当失守的时候,他年仅八岁,但是一达到法定的年龄,他就开始为改变法兰西人的体质作出了不懈的努力。M.I.芬利 H.W.普拉克特 阮光明 1980上海体育学院学报1980,4,2:2
