1Tricept机械手静刚度解析建模方法显示文摘以Tricept机械手的3自由度球坐标型并联机构为例,提出含恰约束支链的球坐标型并联构型装备静刚度解析建模方法。该方法首先借助子结构综合思想将末端执行器位姿变形分解为无约束主动支链的拉压变形、恰约束支链的弯曲变形及其扭转变形3个部分,然后利用虚功原理和结构矩阵法建立各子结构系统的静柔度模型,最后借助线性叠加原理组集整机末端静柔度模型。在建模过程中,侧重研究恰约束支链弯曲剐度以及铰链刚度的建模方法。在此基础上,考察了Tricept机械手中3自由度并联机构静刚度在工作空间中的变化规律,并借助全局性能指标评价了主要构件柔度对整机柔度的贡献。王友渔 黄田 CHETWYND D G HU S J 2008机械工程学报2008,44,8:24

5Terahertz Semiconductor Quantum Well Devices显示文摘For eventually providing terahertz science with compact and convenient devices,terahertz (1~10THz) quantum-well photodetectors and quantum-cascade lasers are investigated.The design and projected detector performance are presented together with experimental results for several test devices,all working at photon energies below and around optical phonons.Background limited infrared performance (BLIP) operations are observed for all samples (three in total),designed for different wavelengths.BLIP temperatures of 17,13,and 12K are achieved for peak detection frequencies of 9.7THz(31μm),5.4THz(56μm),and 3.2THz(93μm),respectively.A set of THz quantum-cascade lasers with identical device parameters except for doping concentration is studied.The δ-doping density for each period varies from 3.2×1010 to 4.8×1010cm-2.We observe that the lasing threshold current density increases monotonically with doping concentration.Moreover,the measurements for devices with different cavity lengths provide evidence that the free carrier absorption causes the waveguide loss also to increase monotonically.Interestingly the observed maximum lasing temperature is best at a doping density of 3.6×1010cm-2.Liu H C Luo H Ban D Waichter M Song C Y Wasilewski Z R Buchanan M Aers G C SpringThorpe A J Cao J C Feng S L Williams B S Hu Q 2006Journal of Semiconductors2006,27,4:2
6生理性线粒体破碎是心脏适应能量需求增加的正常现象显示文摘线粒体在心脏中起着双重作用:负责满足能量需求和调节细胞凋亡。通常认为,线粒体的分裂和碎裂是病理性应激(如缺血)的结果,是线粒体质量差的指标,并导致线粒体自噬和细胞死亡。然而,最近的研究表明,抑制裂变也导致线粒体功能减弱和心脏损害,说明裂变对维持心脏和线粒体生物能量平衡十分重要。刘莉 叶鹏 Coronado M Fajardo G Nguyen K Zhao M Kooiker KB Jung G Hu DQ Reddy S Sandoval E Stotland A Gottlieb RA Bernstein D 2018中华高血压杂志2018,26,1:2
