前负荷的英文
preload
例句与用法
- This project makes some researches with emphasis on the mv / lv distribution power supply situation under the present load condition . some results such as the calculation of line load rate , theoretical line consumption rate and electric voltage decrease are acquired by the mathematical analysis , and thus the power supply capability is evaluated comprehensively . the same has been done to the lv power network
课题在系统搜集分析苏州供电企业的背景资料，即企业概况、电力需求、输电网、高压配电网状况基础上，重点研究了当前负荷下的中低压配电网供电情况，并通过数学分析得出线路的负载率的计算、理论线损率以及电压降等各项运行指标，综合评估得出其供电能力。 - And we also know that we should avoid reducing preload in these patients because reducing preload may cause obstruction of left ventricular outflow tract which is not convenient , so we try to avoid diuretics and nitrates in this kind of patients , but we use calcium antagonists and
我们也知道我们应该避免减低这些患者的前负荷，因为减低前负荷会使本来就很艰难的左心室流出道更加容易阻塞，所以我们都会尽量避免给这类患者使用利尿剂和硝酸酯类药物，但我们经常会用到钙离子拮抗剂和 - Among the pathophysiological mechanisms , the sudden shift from a positie to a negatie intrathoracic pressure plays an important role since it results on the one hand in an increased pressure gradient for systemic enous return and in cardiac preload and on the other hand in a decreased pressure gradient for left - entricular ejection and an increase in left - entricular afterload
在诸多病理生理学机制中，胸内正压向胸内负压的突然转换扮演了重要作用，一方面，是由于增加了体循环静脉回流的压力梯度和心脏前负荷，另一方面，降低了左室射血的压力梯度并增加了左室后负荷。
