结构物对爆破振动荷载的动态响应，是其对于不同优势频率的细节信号的不同的动态响应的叠加的结果。
Under blasting vibrating load, the dynamic response of the structure results from the superposed results of its dynamic response to various dominating frequency detail signals.
由于隧道开挖采用多段微差爆破，所以多数实测爆破地震波中存在多个优势频率峰值，能量带分布很宽。
Multi-millisecond blasting is used in tunnel excavation, so there are several dominating frequency peak values in actual observation blasting seismic, and the energy distribution belt is wide.
如果降低执行的频率，就能提高xml列相当于分解的性能优势。
If you commit less frequently, you can increase the performance advantage of an XML column over shredding.
