Torsades de pointes is a special form of polymorphic ventricular tachycardia. It is characterized by continuously changing morphology of the QRS complexes that seem to twist around an imaginary line, rate dependence, underlying QT prolongation and the so called "long-short initiation sequence".

Torsades de pointes是一种特殊形态的多形性心室频脉，其心电图的特徵包括：QRS波的形态会一直改变，彷佛缠绕著一条假想的线；另外它的发作常与心博过缓有关，合并有QT间距延长，及以所谓「长-短」的序列而开始。

Early or too small to walk on the regular stations, there is going to be bent leg, the doctor said to be x-shaped legs, I guess it should be a big distance between the lower leg, she has a two-year-old, the best solution to see a doctor, and the smaller the better.

走路早或是太小是就经常站，是会引起小腿弯曲的，医生说是x形腿，我估计应该是小腿间距大的，她已经两岁了，最好去找医生解决，而且越小也好的。

The results showed that the surface architecture and ultrastructure of gills filaments and secondary gill lamellaes of the largemouth and the blue gill were similar to other teleosts.

结果表明：大口黑鲈和蓝鳃太阳鱼鳃的表面结构和微细结构与其它硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的上皮细胞所覆盖，表面观凹凸不平；大口黑鲈鳃耙的尖齿直径和长度分别为蓝鳃太阳鱼鳃耙的3.4~3.8倍和2.1~3.8倍；两种鱼的鳃丝末端略为膨大呈勺状，鳃丝表面都具有规则或不规则分布的环形微峙、沟、坑、孔等结构；大口黑鲈鳃丝之间的距离相对较大，蓝鳃太阳鱼的鳃丝间距离仅为大口黑鲈的83%~88%；大口黑鲈鳃小片的高度、厚度和片间距都大于蓝鳃太阳鱼。

The result showed that the surface architecture and ultrastructure of I.punctatus ' gill and secondary gill lamellae were similar to those of other teleosts. The surface of gill arches and gill rakers was covered with pavement cells which were characterized by circular microridges, and secreting-holes were found among cells on the surface of gill arches. The base part of gill rakers were bigger in terms of diameter. The pavement cells' surface of gill filaments' middle part was characterized by microridges with fine lateral protuberances on both sides which were either fused or interruped, while the microridges disappeared on the pavement cells' surface on both top and base parts of gill filaments, forming dense granulated protuberances. The height and interlamellar space of secondary gill lamellae in I.punctatus were relatively higher and bigger, respectively.

结果表明，斑点叉尾鮰鳃的表面结构和微细结构与其他硬骨鱼类基本相似，鳃弓和鳃耙表面被具环形微嵴的扁平上皮细胞所覆盖，鳃弓表面细胞之间有孔洞；鳃耙基部较粗壮；中部鳃丝上皮细胞表面的微嵴两侧有细小的横突，有些微嵴出现融合或间断；端部和基部鳃丝上皮细胞表面的微嵴消失，形成密集颗粒状突起；鳃小片的高度和片间距较大。

Main advances of research on vortices in pump sumps;2. Based on flow field analysis,it shows that owing to the wakes behind the upstream suction pipe,the downstream flow becomes more turbulent and appears with obvious free-surface vortices and submerged vortices in complicated movement.

本文在玻璃水槽内对不同管间距条件下的吸水管周围进行了大量的PIV流场量测实验，通过流场分析显示，上游吸水管的尾流作用加剧了下游吸水口的水流紊动强度，流场多处出现表面旋涡和水内旋涡，其运动形态复杂多变。

In the multi-storey and tall building structures of reinforced concrete, the foundation of double or more columns usually needs to be designed into a whole because of being subjected to the influence of many factors such as the distance of column axes, the load of superstructure and the property of subsoils. This kind of double or more columns combined foundation is widely used in the engineering.

在钢筋混凝土多、高层建筑结构中，因受柱间距、上部结构荷载、地基土特性等多因素的影响，常常需要将双柱、甚至多柱的基础设计成一个整体，这种双柱或多柱的联合基础在工程中应用十分普遍。
