beating pressure 中文意思是什麼
beating pressure
解釋
打漿壓力-
Her countenance, a natural carnation slightly embrowned by the season, had deepened its tinge with the beating of the rain - drops ; and her hair, which the pressure of the cows flanks had, as usual, caused to tumble down from its fastenings and stray beyond the curtain of her calico bonnet, was made clammy by the moisture, till it hardly was better than seaweed
她的臉本來是一種天然的淡紅色，現在被秋天的太陽曬成了淡褐色，上面落滿了雨點，顏色變得更深了她的頭發由於擠奶時受到奶牛肚子的壓迫，現在已經鬆散開了，亂七八糟地從頭上戴的白色帽檐里披散下來，讓雨水淋得又粘又濕，后來簡直比海草強不了多少。 -
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
在心臟機械電反饋的研究中準確控制機械刺激是非常重要的.本研究室構建了一套適用於離體家兔心臟的心室壓力鉗系統.該系統通過計算機控制壓力鉗，不僅能模擬正常生理條件下左心室的壓力波形，還能在心室活動周期的特定時相、以適當波形對心室施加機械刺激.該系統集心臟灌流與起搏、表面心電圖記錄、單相動作電位記錄、心室壓力鉗制與測定等多種功能於一體，特別適用於器官水平上觀察機械電反饋現象並探討其機制 -

At last, the heart beating speed and blood pressure of taxi drivers and the response time are measured after the vibration duration is 0, 2, 4, 6, 8, 10 hours. the phenomena that response time is longer and longer, the rate of heart beating is faster and faster and blood pressure raises firstly and then decreases are founded. the drivers will suffer from fatigue in about 8 hours
最後，本論文在國內外首次對出租車駕駛員工作0 、 2 、 4 、 6 、 8 、 10小時后的心跳速度和血壓這兩個生理指標及反應時間進行了測量，並發現隨著工作時間的增加，出租車駕駛員的反應時間逐漸加長，心跳速度逐漸增加，駕駛員的血壓先增加后降低;發現出租車駕駛員大概在工作8小時之後疲勞，與駕駛員的主觀感覺完全吻合;通過計算，職業駕駛員疲勞時對應的估計振動劑量值為: 11 . 12ms - 1 . 75 ，依此可以將此研究成果推廣到其他類似出租車駕駛員的職業駕駛員的疲勞判別中，從而可以制定出更合理的作業時間。
