Therefore, it is necessary to introduce a way to analysis or to predict ships in operation in sea statetrajectory of the simulation.
因此，有必要引入一种能够分析预报船舶在作业海况中运动轨迹的模拟方法。

The statetrajectory of system is chattering, which restrict it's actual applications. In the circumstances, the arrival condition and the existence condition have been changed .
That's because we open our eyes to see, this is also the positive philosophy of quantum mechanics, see change, when we pay attention to the trajectory of the quantum, the state will happen.
