The method has been applied to the synthetic and real data, and compared with high-pass filtering methods. The processing and comparison results show that the proposed method is effective in attenuating ground-roll, at the same time, it can well preserve the amplitude and phase information of reflection wave.

文中将该方法用于模型及实际炮集资料的处理，并与常用的高通滤波方法进行对比，结果表明，该方法在衰减面波干扰的同时，能更好地保持反射波的振幅及相位信息。

The results show that the vehicle acceleration, the dynamic wheel load and offload factors increase with train speed, and distribute linearly. The safety of train operation and running comfort can meet the requirements when the high-speed train under secondary suspension passing through ballasted track subgrade structure. The dynamic displacement of the system is less influenced by train speed. The dynamic stress of subgrade surface increases with speed improving, and it is distributed as saddle along the lateral direction and as parabola along the longitudinal direction of subgrade surface. The dynamic stress of subgrade declines sharply along the depth of subgrade. The dynamic stress on 3 m depth below subgrade bed surface is about 16 percent of that of subgrade surface.

结果表明：车体加速度、动轮载和轮重减载率均随车速的提高而增大，呈线性分布；具有二系悬挂的高速列车通过有砟轨道路基结构时，列车的安全性及舒适度均能满足要求；系统动位移受速度影响较小；路基面动应力随速度的提高而增大，并在横向呈马鞍形分布，在纵向呈抛物线形分布；路基动应力沿路基深度方向衰减较快，在基床表面下3 m处，动应力只有基面的16%左右。

can be drawn by analyzing the experiment data:(1) With modeling indoor garbage column leaching test, the results indicated that the dynamic change of the pollution components of leachate display complex fluctuate attenuation; During the course of initial stages and middle stages, the garbage was decompounded quickly and gave out the quality concentration of pollutant maximally to the environments and the harm was also the most serious.

通过对试验数据进行整理分析，得出了如下结论：(1)通过室内垃圾柱淋滤模拟试验，结果表明淋滤液中污染组分的动态变化呈复杂的波动衰减；垃圾在填埋过程中，初期和中期降解速度很快，向环境中释放的污染物质量浓度最大，对环境造成的危害也最为严重。

Also, the efficacy of lysing depends not only on the electric field but, more importantly, on the temporal extend which the cell is exposed to the field strength required for lysis as the cell proceeds downstream.

经由FEMLAB的电场模拟以及MATLAB计算有效体积比率，结果显示3D电极电场不会随著微流道的高度而衰减且具有较均匀的分布，另外3D电极的有效体积比率也优於平面电极。

The accelerating erosion of biodiversity, often associated with overfishing, presaged a "global collapse" to the point, in 2048, where all species currently fished would be gone, they said.

他们说，经常与过度捕捞有关的生物品种的加速衰减，预示&全球灭绝&到2048年将达到这样的程度，到那时，现在被捕捞的所有物种都将灭绝。
