| 1. | Seismic signals are stored digitally in binary code .
地震信号是以二进制编码的数字形式储存的。 |
| 2. | It is that energy conversion that is responsible for the violent impact against the earth that generates the seismic signal .
就是这种能量转换引起对地层的猛烈冲击，从而产生了地震信号。 |
| 3. | De - noising of seismic signals using wavelet transform
地震信号去噪的小波方法研究 |
| 4. | Hilbert - huang transform spectrum and its application in seismic signal analysis
黄变换谱及其在地震信号分析中的应用 |
| 5. | Application of fractal box - counting dimension to analysis of blasting seismic signal
基于分形盒维数的爆破震动信号研究 |
| 6. | We analyze also the theoretical method of wavelet decomposition , as well as network learning and training from seismic signals
分析了利用地震信号进行小波分解和网络学习、训练的理论方法。 |
| 7. | The high - frequency components of seismic signals are attenuated more rapidly than the low - frequency components as seismic waves propagate
这就导致低频部分相对增加，使主频向低频方向移动。 |
| 8. | The thesis mainly discussed the realization with software and hardware of the seismic signals detecting and target identifying microsystem
本文重点讨论了小型便携式地震动目标探测识别系统的软、硬件实现。 |
| 9. | The phased array seismic signal detection result is given and compared with single and combination vibroseises under the same experience condition
在给定条件下，与单震源地震和组合震源地震相比，相控地震的信噪比最高。 |
| 10. | Bombast notwithstanding , the small size of seismic signals from the tests of both countries has cast doubt on the declared explosive yields [ see illustration on page 74 ]
试爆后，两国宣布的爆炸威力却让人怀疑，因为造成的地震幅度很小（见50页插图） 。 |
