There are velocity and acceleration dynamic lag errors in the Model I system .

I型系统存在 速度、加速度动态 滞后误差。

The change of velocity should be noticed during the data treatment because of the velocity lag .

数据处理时要注意到由于来 流 风速 的 滞后而产生的速度变化。

We designed a TV auto-tracking system of photoelectric theodolite for taking high-precision tracking of the targets with rapid velocity and high acceleration . We utilized the technique of velocity lag compensation acceleration lag compensation and double closed loop control system in the design .

为了精密跟踪速度快、加速度大的被测目标，采用双闭环控制策略，及 速度 滞后补偿和加速度滞后补偿技术，设计了光电经纬仪电视自动跟踪系统。

When analysing the longitudinal damping moment not only should the pitching damping moment caused by the pitching angular velocity be considered but the damping moment of the lag of wash caused by the angle of changing rate be calculated .

分析纵向阻尼力矩时，除考虑w＊z引起的俯仰阻尼力矩 Mwzzwz外，还应估算出dαdt引起的洗 流 时差阻尼力矩Mαzα。

It is found that the more lag of the diversification of velocity profiles relative to the averaged velocity in diffuser / nozzle components the less lag of the diversification of flow relative to the diversification of pressure the flow of the micropump increase more greatly .

研究发现扩张管/收缩管组件中速度波形的变化相对于 速度的滞后越大，流量的变化相对于压强 滞后越小则越有利于流量的提升。
