在对水下单气泡运动受力分析及任意时间剖面多气泡运动特性研究的基础上，建立了水下气泡群运动数学模型。

Based on the force analysis of single bubble movement and movement characteristic research of many bubbles in random time section, the mathematics modeling of many bubbles movement was built up.

最后的模拟实验数据表明优先级调度输入—线群多通道输出ATM交换系统模型较好地改善了HOL阻塞，提高了输入排队ATM交换网络的性能。

The final simulation experiment shows that the new model can better the HOL block, and improve the performance of input-queued ATM switch dramatically.
