轴管

Methods:Axial and coronal scaning were performed in 50 persons (100 ears),and facial nerve canal was observed with MPR in multiple angles.

对50例（100耳）进行了轴位、冠状位扫描，并对面神经管进行了多角度的MPR观察及测量各段的长度与角度。

Noggin induces the nerve tube formation. It binds and inactivates members of the transforming growth factor-beta superfamily signaling proteins, such as bone morphogenetic protein-4 (BMP4). Proximal symphalangism (SYM1) and multiple synostoses syndrome (SYNS1) are related to noggin mutations.

Noggin能使紫外线人工腹侧化的爪蟾胚胎重新恢复背-腹的身体轴；在神经系统中诱导神经管的形成；减弱包括骨形态发生蛋白在内的转化生长因子信号蛋白的活性，从而控制骨的生长；调控生殖系统的发育。

For the case of deep oil well, pumping rod is eccentric in oil tube during the oil recovery.

在采油过程中，由于油井较深的缘故，抽油杆在油管中是处于偏心位置的，聚驱井产出液在抽油杆做轴向运动的井筒中的流动问题就是非Newton流体在内管。。。

The flowfield numerical simulation of the axisymmetric jet emanating fromthe organ-pipe nozzle is made with the turbulence κ—ε two equations model, providing the basis for improving its cleaning ability.

采用湍流κ-ε二方程模型对风琴管式喷嘴内外流场进行数值模拟，弄清其流场的流动特性（轴向速度、径向速度的分布规律和衰减规律），为提高清除岩屑效率提供依据。

The propeller shaft may be solid or hollow,protected by an outer tube or exposed.

螺旋桨轴可能是固体或空心，保护了外管或暴露。

The results show that the tangential velocity distribution in the annular space shows a typical feature of strongly swirling flows and it consists of quasi-free vortex area and quasi-forced vortex area.

由于流体与双侧壁面之间的摩擦造成能量损失和湍流能量耗散，导致最大切向速度不断衰减且位置沿轴向向下逐渐向提升管外壁移动，同时涡量传递造成外部的准自由涡区逐渐增大，内部的准强制涡区逐渐缩小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
