查询词典 vena

By means of the present model certain phenomena related to the nonlinear acoustic properties of an orifice, such as the roll-up of the shed vortex sheet and the forming of the Vena-Contracta are simulated. For a sinusoidal sound pressure, the time- history of the average velocity through the orifice is computed, and the nonlinear distortion of the velocity is examined by means of the Fourier decomposition.

依据此模型，对圆孔声学非线性效应的若干特征现象进行了数值模拟，如脱落涡层的卷曲，Vena收缩段的动态形成；在孔板前声压按余弦规律变化的情况下，计算了孔中平均速度的时间历程，并借助于Fourier分解分析了孔中平均速度的畸变情况。

Methods 22 patients undergoing elective surgery were divided into two groups randomly:group HVH and group IVH.After induction of anesthesia, blood was withdrawn via radialis artery while Ringer's lactate solution with threefold the volume of blood withdrawnor Dextran 40 with the same volume as blood withdrawnwas infused in big peripheral vena with identical speed.

选择22例外科择期手术病例，分为HVH和IVH两组，于全麻稳定后，经桡动脉采血，同时外周大静脉匀速输入3倍于采血量的乳酸钠林格液或等于采血量的右旋糖酐施行血液稀释。

Apllied the data of QuickBird-2——the highest resolution remote sensing,and based on the theory and methodology of fractal geometry,we have quantitatively studied remote sensing lineations in Gaolong gold deposit of Guangxi.

采用Quick Brid-2高分辨率卫星遥感数据，通过分形几何学的盒计维数法，定量研究广西高龙金矿区遥感线性构造。

So, sometimes, to change the color can not be your food (referring to the above-mentioned crustacean) has been a sign of boiling over.

所以，有时，来改变颜色，不能你的食物一直是沸腾了的迹象。
