at given speed的意思|示意

The curl actually measures twice the angular speed of a rotation part of a motion at any given point.

旋度实际上衡量的是，在任意给定点,运动旋转角速度的两倍。

Astronomers who study star clusters have noticed that the speed at which a star of a given mass spins (measured by tracking cool, dark spots on the surface) also seems to vary predictably with age.

研究星团的天文学家已经注意到质量一定的行星(通过追踪表面阴暗冷却斑点来测量)，其旋转速度随着其星龄呈现可预测性的变化。

The number of times your network reconnected within a given time frame at a lower network speed is not as acceptable as the same number of times the network reconnected at much higher network speed.

如果一个低速网络和一个高速网络在一个给定时段内的网络重新连接次数相同，那么相比之下，低速网络上的这一重新连接次数更加令人难以接受。
