The airborne processing system can simultaneously and continuously detect and track the presence and motion of thousands of small or large targets over an area covering tens of square miles.
机载处理系统能够同时和连续地探测和跟踪数十平方英里面积内出现的数千个小型或大型目标。

Even slight spiraling motion in a square pipe increases the tendency of particles to be maintained in suspension.
水流在方管中稍有一些螺旋运动，将增加泥沙悬浮在水中的作用。

The system is simplified into single degree of freedom dynamics model with piecewise linear restoring forces and square damping, then the piecewise nonlinear motion equation of ALT is established.
