注意时间步长和迭代数是完全无关的。
Note that the time step and the iteration count are completely unrelated.
最后给出了根据时间步长推算的飞行轨迹简化计算模型。
Finally, a simplified flight track model was proposed based on time step.
这是一隐式格式，因而可放松稳定性对时间步长的限制。
一旦找到一个稳定的时间步长，进一步减少它不会显著增加解的精度。
Once a stable time step is found, further reduction will not appreciably increase solution accuracy.
