true velocity

For low speed flow problems, because of the highly nonlinear coupling of the low bulk flow velocity and the high velocity of molecules' thermal motion, and usually over-estimate the true flow velocity in such cases and lose its authenticity.

对于低速流动问题，由于较低的流动速度和较高的分子热运动速度的非线性耦合，流体的流速被大大地高估，失去其真实性。

Solving for Nodal True Velocity Field By Gill Murray Method

应用Gill-Murray法迭代求解节点真实速度场

The player must practice repeatedly, follow in order and advance step by step, adopt various strength and velocity, according to the contents and style of the music works, to create the artistic images true to life.

弹奏者必须在循序渐进、反复训练的基础上，根据作品内容与风格的具体要求采用不同力度与不同速度弹奏，才能塑造出栩栩如生的艺术形象来。
