Methods To observe synchronization in 7 left bundle branch block patients. 15 right bundle branch block patients and 21 normal subjects by tissue synchronization imaging and tissue tracking, 6 ventricular regional myocardia were assessed.

运用组织同步成像和组织追踪技术，观察7例左束支传导阻滞、15例右束支传导阻滞患者及21例正常人的心肌6个节段的收缩起始时间、收缩达峰时间，计算时间差值和标准差。

The simulation shows that the Corkscrew of beam centroid is a low frequency motion which overleaps the average eccentricity between centroid of beam and axis of accelerator and a dispersive effect.

计算结果显示，束心Corkscrew运动是叠加在束心平均偏轴上的一种横向运动，同时也是一种色散效应。

Image reconstruction from the projections of fan-beam: The CT equipment is broadly adopted on the world that its detectors are arranged on the concentric circle at same angle interval. This equipment rebates the complex machinery movements like parallel-beam geometry, makes the sampling time shorter, that is rebating the whole CT testing time.

扇形束图象重建：将探测器等角间隔排列于同心圆周上采集射线投影数据，然后进行图象重建的CT装置是目前世界上广为使用的，它减少了平行射束采样方式的繁杂的机械运动，可有效地缩短数据采集时间，也就是减少了CT检测的总的花费时间。

When the injection pressure is about 0.1MPa, the air flow through the injector becomes critical, so if the swirl level variation reaches the required range, the pressure should be kept as low as possible.

空气射束的喷射压力越大，涡流比的变化范围也越大。而当喷射压力达到0.1MPa左右时，空气在喷嘴内的流动已接近临界状态。因此，射束喷射压力不宜过高，在满足涡流变化要求的前提下，喷射压力应尽量低一些。

Kenaf phloem bundle fiber layers were separated with a acidified sodium chlorite treatment with an additional ammonium oxalate treatment.

采用亚氯酸钠冰醋酸和草酸铵处理，将不同部位的红麻韧皮部束纤维进行分层，并-测定各束纤维层的纤维细胞长度，探讨红麻韧皮部纤维细胞长度的分布规律。

Measurement of radial and azimuthal current density on the beam cross-section in different time and energy fluence on beam spot center with 13% more than its average value for the beam is also presented.

测量还给出了不同时刻束截面上的径向和角向束流密度分布，而束斑中心处的能注量高于平均值约13%。

Compared with the result of plane wave, additional beam factor represents the effect of Gaussian beam, which is related to beam waist size, distance from beam waist to object center and the illuminated area on object, together with the incident or scattering angles.

与平面波解不同的是，在公式中引入了波束因子这一表征波束作用的重要参量，该参量与束腰半径、束腰中心与物体中心距离和物体照射面积以及入射、散射方向有关。

It basically consists of a ring cavity around which there are two laser beams traveling in the opposite direction, one clockwise and the other counterclockwise, and the beat note of the two counter propagating beams is proportional to the rotation rate of the ring cavity relative to an inertial frame.

其原理是在环形谐振腔内运行着顺逆两束激光，这两束光的频差与外界的角速度成正比。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
