一旦此调用针对当前时间步长返回，就可以清空上一步长施加到这些物体上的力，然后获得动态物体的当前方位和角度。
Once the call returns for the current time step, you clear the forces applied to the objects from the last step, and then get the current position and Angle of your dynamic body.
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.
文末的数值算例进一步表明，精细积分法对大的时间步长和长时间计算均有效，因此是一种很实用的方法。
Results show that this method has high accuracy even for very large time-step sizes, and possesses excellent long-time numerical calculation behavior.
