- METHODS: The measurement parameters included: peak velocities at rapid filling (VE) and atrial contraction (VA), the ratio E/A, deceleration rate of early diastolic rapid inflow (EDC) and E-F slope of mitral valve forelobe curve (EFV). 方法：以舒张早期快速充盈血流速度（VE）、舒张晚期心房收缩血流速度（VA）、二者比值（E/A）、舒张早期快速充盈减速度（EDC）及二尖瓣前叶EF斜率（EFV）为测量参数。
- Methods 85 patients suspect coronary heart disease, with echocardiography, the peak flow velocities during early diastole (E), atrial contraction (A), E/A ratio were recorded and calculated. 方法85例临床疑诊冠心病超声检查左心室二尖瓣口舒张早、晚期血流充盈速度E、A两峰峰值,计算E/A比值,其结果分为舒张功能正常和降低两组。
- Mitral inflow velocity, left atrium contraction inflow velocity in early diastole and their ratio were detected by Doppler flow imaging.Difference of the index of the two groups was compared. 并用二尖瓣血流多普勒法检测舒张期早期血流速度峰值、左心房收缩期血流速度峰值及二者比值，比较两组间所测指标的差异。
- Some developers also defer to the buyer request, conclude and sign contract time delay to next month. 有的开发商还按照买家要求,把签订合同时间延迟至下个月。
- A cumulative severer punishment would be received by the employee when second punishment performing that occured during the employee contract time. 员工在第一次受处分后，劳动合同期内如再受处分，则将受到累计升级处分。
- GET was delayed in 66% of 64 FD patients as compared with that of control, and it was related with gastric contraction initiating time and contraction times in 2 min. 64例FD患者中有 66%25存在胃液体排空延迟 ,且与胃起始收缩时间和 2min收缩次数相关。
- I recently bought a whole renovation auction, contract time, I found a clear contract in the decoration equipment brand models, and annotated "or other products of equal value". 问：我最近购买了一套全装修期房，签订合同的时候，我发现合同中在明确了各个装修设备的品牌型号后，又注明“或其他同等价值产品”。
- dropped premature atrial contraction 脱落的房性过早收缩
- Helmholtz-Kelvin contraction time 亥姆霍兹－开尔芬收缩时间
- At the end of diastole, your heart’s atria contract (an event called atrial systole) and pump blood into the ventricles. 当舒张期结束时，心房收缩（称为“心房收缩期”）将血液压入心室。
- We are pleased to inform you that we have got the goods ready two weeks in advance of the contracted time and that we can see effect shipment as soon as your L/C reaches us. 我们高兴地通知您方，我们已比合同时间提前两周将货物备妥，只要您方信用证一到，我方即能立即装船。
- At the end of diastole, your heart’s atria contract (atrial systole), pumping blood into the ventricles, and then begin to relax. 舒张期一结束，心房就首先开始收缩（心房收缩期）将血液压入心室，然后开始放松。
