A key problem of synthetic seismogram is the problem of wavelet.

而子波问题则是制作合成地震记录中的关键问题。

We present a mathematic expression of the changing wavelet model of the seismogram.

本文给出了地震记录变子波模型的一种近似数学表达式。

From the results it showed that the method has good effects in synthetic seismogram inversion with different resolution, signal to noise ratio and phase.

试算结果表明，粒子群优化算法在不同分辨率、不同信噪比、不同相位子波合成的地震记录反演中效果明显。

This paper gives a time-synchronization technique bases on GPS time service signal which is used in broad band seismic recorder.

本文给出了一种应用在宽频带地震记录仪中基于GPS授时信号的时间同步技术。

In order to investigate the dynamic behavior of experinent simulation and behavior in situ, the numerical models under different slope and design parametes are established. The vibration forces are simulated from simple harmonic motion and from real earthquake records. The deformation of geosynthetic reinforced soil wall and interior failure surface generated the wall are also investigated.

为了解试验模拟与现地受振动之动态行为，建立不同坡度与设计参数之分析模型，其振动力分别为简谐振动与真实地震记录，并藉由数值模拟的方式，探讨不同振动力对加劲挡土设施之墙面变形与土体内部产生破坏面之动态反应。

Through poising seismic records in the direction of space, this method avoids the assumption that multiple events are orthogonal to the primary events.

该方法通过在空间方向上对地震记录进行均衡，避免了多次波和一次波同相轴正交的假设条件。

He saw several little blips and spikes, probably echoes of sonic thunder, but no major seismic events.

他看到了好几个点和尖峰，这些大概是炸雷的声音吧。不过还好没有地震记录。

The time-frequency peak filtering based on pseudo Wigner-Ville distribution was applied to process common shot point seismic record to eliminate the noise.

针对这一问题利用基于伪Wigner-Ville分布的时频峰值滤波技术处理共炮点地震记录。
