The small-disturbance model is actually valid for disturbance magnitudes that seem quite violent to human occupants . 既使对于人来说似乎已是十分剧烈的扰动值，小扰动模型实际上仍是正确的。

The td - disturbing - valued fuzzy normal subgroup 型扰动值模糊正规子群

The simulated results for a certain howitzer show that the muzzle disturbance can obviously be reduced after optimized ; niche genetic algorithm can search out several effective schemes to favour the flexibility of general layout for the howitzer 结合某火炮，对上述方法进行了计算，计算结果表明：优化后的炮口扰动值比优化前明显降低；小生境遗传算法一次可以搜索出多个有效方案，给火炮总体布置带来更大灵活性。
