速度梯度 meaning in English
gradient of velocity
gradient velocity
velocity gradient
Examples
- Therefore , we can conclude that the velocity gradient of fluid around a fiber is the key for its rotation
于是得出结论：纤维附近流体的速度梯度是导致纤维旋转的主要因素。 - Prophase studies about the coagu - flocculation mechanism lay particular stress on collision mechanism and the theory of velocity grads , but reseau coagu - flocculation can ' t inosculate in the practical applications
前期对混凝机理的研究偏重于碰撞机理和速度梯度理论，但实际应用中的网格混凝不能吻合。 - It is found that drag reduction occurs with adequate wavenumbers and grows with an increase of h . the mechanisms are revealed through variations of velocity profile and the decrease of wall shear stress
分析减阻机理是流速分布曲线及近壁区速度梯度介于层流与湍流之间， h值增大引起壁面剪应力显著下降。 - If increasing drawing interval , the movement and flow range of top coal will enlarge , and the velocity gradient on flow cross - section will diminish , so that it is good for controlling the flow rate of thin sand among loose top coal
研究表明，加大放煤步距，顶煤运移流动的范围变大，流动断面内速度梯度变小，有利于控制细砂的下窜速度。 - Specifically , we present a full velocity difference ( fvd ) car - following model , a cellular automata ( ca ) model that considers the velocity effect of the preceding car , another ca model that can describe the synchronized flow , and a speed gradient ( sg ) macroscopic model which can describe the anisotropic properties of traffic flow
具体地说，我们提出了一种全速度差车辆跟驰模型，一种考虑前车速度效应的元胞自动机模型，另一种能较好模拟同步流的元胞自动机模型，以及一种能体现交通流各向异性特征的速度梯度宏观连续模型。
