For an extended image, sa would reduce the contrast and degrade the details . 對于一個擴展的圖象,球差會減少反襯度并使圖象的細(xì)節(jié)模糊。
From the sa node, electrical impulses spread through the heart muscle to trigger the heartbeat . 從竇房石結(jié)出來的電脈沖傳播到心臟肌肉觸發(fā)心臟跳動。
This is particularly important when the conducting tissues between the sa node and the ventricles fail only from time to time . 尤其在竇房結(jié)和心房之間的傳導(dǎo)組織有時發(fā)生故障時這點尤為重要。
An "atrially triggered" pacemaker can pick up the signals directly from the sa node and strengthen them before passing them to the ventricles . 一種“心房觸發(fā)式心博器”就能從竇房結(jié)直接接收這種信號,并在傳送到心房去之前還能將這種信號進行放大。
Sa : i will have an absolute straight up , please 山:我來一杯不加冰的純伏特加。
