However, these methods can't suppress the frequency component in the surge.

但是这种方法难以抑制涌流中的高频分量.

By using the model, the vibration level can been predicted accurately but the frequency component.

简化模型虽然能较准确的预测出地面振动的强烈程度,但在分析振动频率成分方面存在着不足.

In order to control the frequency component in the surge, the low - pass filter was used widely.

对于浪涌中的高频分量的控制, 广泛应用的是低通滤波器.
