The experimental results by using all of ECG records in MIT-BIH Arrhythmia Database are that the whole classification accuracy is ( 93.93 % ) for normal beats and 93.94 % for premature ventricular contraction ( PVC ) beats .

通过使用MIT-BIH心律失常数据库的所有数据集进行测试，正常心拍的总识别率达到93.9%，室性 早搏心拍的 总识别率达到93.94%。

This is really a difficult time for you because your whole life has been vision excitement recruiting positive growth and suddenly you are faced with contraction .

这段时间对你来说很困难，因为你 整个人生就是设想，激情，招聘，积极成长，而突然你就面临着 收缩。

Because the Ang ⅱ has strong vascular contractility capacity interacting with receptor AT-1 Ang ⅱ role in the vascular smooth muscle stimulates the whole body arteriole contraction leads to high blood pressure .

因为ANGⅡ有很强的收缩血管功能，它与AT1受体结合，作用于血管平滑肌，引起 全身微动脉 收缩，导致血压升高。

Pungent-dispersing and falling-down group pungent-dispersing and sweet-nourishing group and the whole recipe group could obviously quicken the contraction frequency .

辛开降逆组、辛开甘补组、 全方组能明显加快其 收缩频率。

Falling-down group pungent-dispersing and falling-down group and the whole recipe group could obviously augment the contraction amplitude of esophageal muscle strip .

降逆组、辛开降逆组、 全方组能明显增大食管肌条的 收缩幅度；

During the whole process we examined the flow of coronary artery degree of myocardial contraction heart rate and the concentration of the CK LDH SOD GSH-Px and MDA in perfusion liquid .

测定再灌注 30min后，灌流液中CK、LDH、SOD、GSHpx和MDA含量；同时测定离体心脏冠脉流量、心肌 收缩 幅度和心率。

Our estimates are that we are slightly growing at the moment but we think that there 's a chance that for the first half as a whole there might be a slight contraction .

我们的预估是目前我们的经济在低速增长，但我们认为就 整个上半年 来看，有可能会略有 萎缩。

Both countries ' 0.3 per cent quarter-on-quarter growth yanked up the eurozone as a whole to only a 0.1 per cent contraction .

上述两国经济各自较上一季度增长0.3%，拉动欧元区 整体经济 萎缩幅度收窄至仅仅0.1%。

Results : In the group which no thrombolytic therapy has been taken the left ventricular remodeling can be seen after the one week myocardial infarction with left ventricular leading to ball-shape and bigger cubage and whole and local contraction and diastolic function decreased .

结果：未溶栓治疗组左室重构在1周时已发生，左室趋向球形变化、容积增大、 整体及局部 收缩 功能下降、舒张功能减低。

In this paper the output of the society as a whole expansion and contraction of the study pairs of the process and impact of the economic cycle terms of which were further explored .

本文通过对社会 整体的产出扩大与 萎缩的考察，对经济周期的过程及影响条件做了进一步探讨。
