streamline surface的意思|示意

Push off in streamline and let your body rise to the surface.

蹬出，让身体保持流线型并慢慢地升到水面。

Preferably, the streamline surface of the shell is gradually shrunk from the head to the tail, and the rear openings are symmetrically distributed around the Central Line of the shell.

优选的，所述壳体的表面流线型由头部到尾部逐渐收缩，所述后开口围绕所述壳体的中心线对称分布。

In addition, due to the streamline surface, the shape resistance is reduced, thus lowering the flowing pressure loss and the fluid transportation energy consumption.

另外，重要的是由于其流线型表面，使得形状阻力减小，从而降低了流动压力损失，减少流体输送能耗。

Start with the simple push-off drill, in which the swimmer pushes off and stays in the streamline position until they pop to the surface and stop moving forward.

从简单的有力的游泳练习，游泳运动员结束划水时，停留在流线型姿势直到他们流行于表面，停止前进。

A possibility of automatic detection of the surface streamline position by analysing the oil visualisation images is discussed.

讨论了通过油流显示图像的分析，自动探测表面流线方位的可能性。

In this paper, the finite element method is used for the calculation of S1 streamline surface of Francis turbine runner with half vanes.

本文采用有限元法对带半叶片的混流式转轮的S1流面进行了流场计算。
