1Magnetoelectric and converse magnetoelectric responses in Tb_xDy_(1-x)Fe_(2-y) alloy & Pb(Mg_(1/3)Nb_(2/3))_(1-x)Ti_xO_3 crystal laminated composites显示文摘Measured results of magnetoelectric (ME) and converse magnetoelectric (CME) effects of TbxDy1-xFe2-y/ Pb(Mg1/3Nb2/3)(1-x)TixO3/TbxDy1-xFe2-y (TD/PMNT/TD) and PMNT/TD/PMNT laminated composites are pre- sented. ME effect was determined by measuring laminate voltage output under a Helmholtz-gener- ated AC field biased by a DC field (0―1 kOe) (1 Oe = 79.58 A/m). The CME effect was measured by re- cording the voltage induced in a solenoid encompassing the ME sample while exposed to a DC bias field and PMNT layer driven by a 10 V AC source. The ME and CME responses in the two laminated structure are linear. The highest values of ME coefficients in TD/PMNT/TD and PMNT/TD/PMNT com- posites are 384 mV/Oe and 158 mV/Oe, respectively, while the highest values of CME coefficients in the two composites are 118 mG/V and 162 mG/V (1 G=10-4 T), respectively.JIA YanMin LUO HaoSu OR Siu Wing WANG YaoJin CHAN Helen L W 2008Chinese Science Bulletin2008,53,14:3
2复合材料Terfenol-D/PMNT的磁电和逆磁电响应显示文摘给出了Terfenol-D/PMN-PT/Terfenol-D(TD/PMNT/TD)和PMNT/TD/PMNT两种层状复合材料的磁电和逆磁电响应的测试方法和测试结果.这两种复合结构的优化直流偏置磁场大小均为350Oe(1Oe=79.58A/m).在1kHz频率下,这两种复合材料的最大磁电电压系数分别为384mV/Oe和158mV/Oe,最大逆磁电系数分别为118mG/V和162mG/V(1G=10-4T).另外研究了这两种复合材料在谐振频率下的磁电响应.通过对两种复合结构的比较得知,磁致/压电/磁致复合结构具有好的磁电响应;而压电/磁致/压电复合结构具有好的逆磁电响应.这一结果有助于优化设计高性能压电/磁致复合磁电材料.贾艳敏 罗豪甦 Or Siu Wing 汪尧进 Chan Helen L W 2008科学通报2008,53,10:3

5抗生素使用的时间长短和使用时的生命阶段与全因/特定原因死亡风险的关系:一项前瞻性队列研究显示文摘过度使用抗生素一直是一个重要的临床问题,抗生素使用与肠道微生物菌群的改变有关,肠道菌群的改变与各种慢性疾病如心血管病和癌症的风险有关。此外,抗生素使用的时间可能是过早死亡的一个危险因素。研究者调查了成年期间使用抗生素的生命阶段和使用持续时间与全因和特定原因死亡风险的关系。该项前瞻性队列研究包括来自护士健康研究、均未患有心血管病或癌症的37516名年龄≥60岁的女性,收集其中年(40~59岁)和老年(≥60岁)使用抗生素的时间(无,<15d,15d至<2个月,或≥2个月)。研究者根据抗生素的使用时间估计10年内全因死亡率和心血管病或癌症的死亡风险比(HR)。在355918人年的随访中,研究者记录了所有原因导致的4536例死亡(包括728例心血管病死亡和1206例癌症死亡)刘青(译) 叶鹏(摘 审校) Heianza Y Ma W Li X Cao Y Chan A Rimm EB Hu FB Rexrode K Manson JE Qi L 2020中华高血压杂志2020,28,2:2
