机械刺激 meaning in Chinese
mechanical stimulus
Examples
- The group discovered that chemical and mechanical stimuli both resulted in the same messenger molecule , camp , which acts like a gatekeeper of reactions in the olfactory neurons
该小组发现：化学和机械刺激都能导致相同的信使分子环磷腺苷产生，环磷腺苷是嗅觉神经反应的关键。 - 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 - Abstract : 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

很早以前，人们就认识到机械力的作用对植物生长能产生明显的影响，诸多学者对机械应力刺激的研究结果表明，机械力的刺激在生物内部会产生一系列的复杂生理和化学响应；并且这些响应的强弱与外界机械刺激力的大小和类型有密切的关系。 - These results are consistent with the results from gross and salzstein and so on . osteoblast is the seeded cell of bone tissue engineering . now , in order to research the response of the osteoblast when it is cultured with mechanical stimulating , the paper consider the osteoblast as an homogeneous , isotropic , incompressible viscoelastic medium
由于成骨细胞是骨组织工程的种子细胞，为研究其在机械刺激离体培养下的受力情况，论文将成骨细胞看作是一种均匀、各向同性、不可压缩粘弹性体，然后应用数值方法将物理关系中的遗传积分展开，从而导出物理关系的矩阵形式。
