Contractivity of Interpolation Operators and the Defect Iteration of Finite Elements for Singular Two-point Boundary Problems 奇异两点边值问题插值算子压缩性及有限元迭代校正
Our conclusion is that Ischemic Preconditioning can reduce the necrosis, enhance the preservation of cardiac contractivity and decrease the morbidity of ventricular arrhythmia on the donor heart during canine heart transplantation. 结果提示:缺血预处理对犬心移植中供心具有良好的心肌保护作用,能减轻心肌组织损伤程度,降低心肌收缩力下降幅度,减少室性心律失常的发生率。
Oxygen sensitive potassium channels can sense the change of oxygen pressure and mediate modifications in cell excitability, contractivity and secretory activity. 能够感受氧压变化的钾离子通道称为氧敏感钾离子通道,氧敏感钾离子通道参与调节神经分泌细胞的分泌活动、血管张力及神经元的兴奋性。
Effects of Tobacco Smog Extract on Contractivity of Isolated Rabbit's Aortic Strips 莫合烟烟雾提取物对家兔离体胸主动脉条舒缩活动的影响
In this paper, the numerical stability of multistep Runge-Kutta methods is studied by introducing the concepts of generalized contractivity and weak generalized contractivity. 本文对多步隐式Runge&Kutta方法进行数值稳定性分析。
Objective To detect the regional myocardial contractivity and microvascular perfusion improvement in vivo after bone marrow stromal cells ( MSCs) transplantation by tissue Doppler image ( TDI) and myocardial contrast echocardiography ( MCE) in myocardial infarction rabbits. 目的检测骨髓间质干细胞移植到梗死心肌后局部心肌运动特征和新生微血管的活体灌注状况。
For normal people, whether adults or children, even newborns, the changes of their cardiovascular function, such as cardiac function, myocardial contractivity, cerebral blood flow velocity, blood pressure, heart rate, and electrocardiogram all have circadian rhythm. 在正常人群无论是成人,还是儿童乃至新生儿,其心血管机能,如心功能、心肌收缩力、脑血流速度、血压、心率、心电图等变化均存在着昼夜节律。
