活动周期 meaning in English
activity cycle
Examples
- Elimination ; temperature regulation ; grooming , cleaning of body and nest , and evolution / emancipation of these actions for social uses ; reactions to illness and injury ; sleeping and activity cycles ; nesting re other functions , adaptations
排除；温度调节；整洁，清洁身体和巢，及这些社会用途的行为的演化/解放；对疾病和伤害的反应；睡眠和活动周期；筑巢的其他功能，适应。 - 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

提出了利用进程的每一个活动周期来作为可预测的任务单元的思想和实现方法，从而得到比较精确的工作量估计，并在此基础上提出三级预警的电压调度算法。 - Focusing on the sanyang wetland in wenzhou of china , and inspired by the principle of life and cosmos from taoism , the plan analyses the rules of water regime , lifecycles and cycling human productive behaviors ecologically , and tries to combine them through an efficient spatial - temporal organization to make " everything take its own course naturally " , in order to respond to complex challenges faced by the project : agricultural production , environmental deterioration , flood threat as well as habitat regeneration
选取温州三?湿地为研究对象，汲取道家对于生命和宇宙规律的认识，对水文周期、动植物生命周期和人类生产活动周期的规律进行生态学研究，试图通过经济有效的时空布局将其巧妙嵌套，让万物“自然而然”自行其道，以回应基地面临的农业生产、环境品质恶化、洪水威胁以及栖息地再生等复杂的挑战。
