Here, the velocity is almost constant — it's almost a straight line.
而在这里速度几乎是个常数了-,在这里接近一条直线了。

Is the well-known equation for velocity under constant acceleration. This equation is linear; the slope of the line is the acceleration.
就是众所周知的恒加速度的速度方程。这个方程是线性的,这条直线的斜率就是加速度。

Under the assumption of line movement with constantvelocity, the flight path is built such that prediction error variance computed by the LFR times meets the specified requirements.
