1.The keypoint of mechano-electrical unification design for reflector antennas is brie-fly described.
并简要阐述了反射面天线机电一体化设计的思想。收藏指正
2.It is necessary to control the mechanical stimuli precisely in the studies of cardiac mechano-electrical feedback(MEF).In the present study a ventricular pressure-clamping system has been developed,which can be applied to isolated-perfused rabbit hearts.Controlled by a computer,this system not only can make the left ventricle follow a command defining the same pressure wave as that during a beating cycle under physiological condition,but also deliver mechanical stimuli with a proper waveform to the ventricle at a particular time phase.This system integrates multiple functions,including perfusing,pacing,recording of electrocardiogram and monophasic action potentials,and clamping and measuring of ventricular pressures in isolated-perfused hearts.Thus,it is a distinct system for investigating the phenomena and mechanisms of cardiac MEF at organ level.
在心脏机械电反馈的研究中准确控制机械刺激是非常重要的.本研究室构建了一套适用于离体家兔心脏的心室压力钳系统.该系统通过计算机控制压力钳,不仅能模拟正常生理条件下左心室的压力波形,还能在心室活动周期的特定时相、以适当波形对心室施加机械刺激.该系统集心脏灌流与起搏、表面心电图记录、单相动作电位记录、心室压力钳制与测定等多种功能于一体,特别适用于器官水平上观察机械电反馈现象并探讨其机制.收藏指正
