Zero velocities on the cylinder were satisfied at the node points . 圆柱上速度为零在节点上满足。
Zero velocity surface 零速度面
Zero velocity curve 零速度线
Many vendors use the convention of a noteon with a zero velocity to represent a noteoff 许多厂商习惯使用零速率的noteon来表示noteoff )
Thus , the pressure field is coupled up with the velocity field while keeping zero velocity divergence 拟压缩项的引入使不可压方程在满足速度散度为零的同时耦合了速度和压强的变化。
Adopt zero velocity full auto paper receiving mode , end to end butt paper receiving , auto double side stickup connection adhesive tape so as to avoid spoilage of die cutter and dinkey dint of overlapping paper registration 采用零速全自动接纸方式,头对头对接接纸,自动双面粘贴连接胶带,可避免搭接接纸对印版的压伤及对模切刀具的损坏问题。
When the two objects are at zero velocity , the total energy of the system is zero , because while the rocket ship made of positive matter has gained positive kinetic energy , the ball of negative matter has gained an equal amount of negative kinetic energy 当两个物体的速率都为零,整个系统的能量也为零,因为当正质量构成的火箭飞船获得正动能时,由负质量构成的球体也获得了等量的负动能。
When the intensity of the laser field is weak , the velocity dependence of the average longitudinal force has the doppler shifted lorenztian resonance . at high intensities , there is a kink and change direction of the light pressure force near the point of zero velocity , the effects of the higher order harmonic light pressure forces become significant 当激光场强度比较弱时,作用在原子上的力为洛仑兹型,随着激光强度的增加,依赖于速度的零阶力在零速度附近方向发生了反转,出现了扭结现象。
The calculated results indicate that maneuvering efficiency of the bow lateral thruster is related to velocity and thruster ' s rotate speed directly , it is the best at zero velocity , and maneuvering efficiency of the bow lateral thruster increase with increasing thruster ' s rotate speed ; the calculated results also indicate that crabbing motion can be operated for large vessels under the main thruster , the bow lateral thruster and the rudder ' s united control 计算结果表明侧推器操纵效能与航速及桨转速直接有关,零航速最好,且随桨转速增高而增强;结果同时也表明了借助于主推进器、首侧推器和舵的联合操纵可实施纯横移运动。
