1强迫振动方法确定黏弹性细棒的复杨氏模量显示文摘提出了一种方法一强迫纵振动法(该计算方法不同于以前的梁振动法)来确定黏弹性样品细棒的杨氏模量。在室温下,对长度分别为108 mm,100 mm,90 mm,83.5 mm,80 mm,74.5 mm,70 mm的聚碳酸酯细棒,实验测试得到了棒两端的振幅比与激励频率之间的关系曲线,并由曲线的3 dB带宽计算得到损耗因子,进一步得到棒的储能和耗能杨氏模量。依照这种方法,只要能得到足够多的数据,用最小二乘算法,可得到在感兴趣的频段内该材料相应的杨氏模量随频率变化的曲线。若测试频率步长减小到5 Hz,则测试最大误差可小于6%。与现有测试方法相比较,本方法计算简单,物理意义清晰。贺西平 Avraham Benatar 2012声学学报2012,37,2:6
2Determination of complex Young's modulus of viscoelastic bars using forced longitudinal vibration of slender rods显示文摘A method to identify complex Young’s modulus of viscoelastic materials using forced longitudinal vibration of slender rods is proposed.The method differs from the beam one.Experimental tests were carried out at room temperature with different lengths in 108 mm, 100 mm,90 mm,83.5 mm,80 mm.74.5 mm,70 mm for the polycarbonate bars,and the curves of ratios A2/A1 between two ends of a viscoelastic bar versus frequencies are obtained, furthermore,the corresponding 3 dB bandwidth and the storage and loss modulus can be calculated.Sufficient number of obtained complex Young’s modulus at different frequency allows us to calculate other ones using the least square method.If the step of the tested frequency is 5 Hz,the maximum error of results can be less than 6%.By comparison with the measurement methods which the previous literature mentioned,this new method simplifies the calculation,and the physical meaning appears apparently and clearly.HE Xiping Avraham Benatar 2013Chinese Journal of Acoustics2013,32,1:4
3伦理学与SARS:多伦多的教训显示文摘SARS的流行说明传染病在世界范围内流行是件多么容易的事,为了更好地应对下一次流行病,我们不仅要解决医学方面的问题,也同样需要解决伦理学方面的问题。Peter A Singer Solomon R Benatar Mark Bernstein Abdallah S Daar Bernard M Dickens Susan K MacRae Ross E G Upshur Linda Wright Randi Zlotnik Shaul 肖月 2004英国医学杂志中文版2004,7,4:3
4美国重症肌无力基金会关于重症肌无力临床试验的建议显示文摘由美国重症肌无力基金会(MGFA)的医学科学建议委员会(MSAB)组成工作组,于2010年在美国和2011年在意大利召开专家共识会议讨论重症肌无力(MG)临床试验的问题,与会代表包括来自美国和欧洲的神经科医生、统计学家、企业界代表、MG患者以及MGFA和欧洲重症肌无力协会的平民代表。Benatar M Sanders DB Burns TM Cutter GR Guptill JT Baggi F Kaminski HJ Mantegazza R Meriggioli MN Quan J Wolfe GI 李海峰(摘译) 高翔(摘译) 2013中国神经免疫学和神经病学杂志2013,20,1:2
