ATP simulation and tests of the real recording oscillograph data of fault occurred in East China Power Grid prove that the model has the advantages of high classification rate and convergence speed.

通过AT P仿真及华东电网实际故障录波数据的测试，结果表明该模型具有很高的识别率和收敛速度。

When the number of grid is very great or viscous effects dominates or sometimes the speed of flow is low, the rate of convergence slows down dramatically, resulting in inefficient solution technique.

流体力学控制方程的数值求解过程中，当网格加密、粘性效应强或来流马赫数低的时候，流场收敛非常缓慢。

In addition, the demanding technical specification is still indispensable factor, which accords with the special bandwidth demand of the grid drive pulse in measuring the convergence error.

此外，为符合会聚误差测量中栅极驱动脉冲特定带宽的要求，脉冲的高技术指标仍然是不可缺少的因数。
