| 摘 要： | 使用北京台网记录的数据，利用功率谱方法对中海油渤海勘探部在渤海湾进行的气枪试验进行了分析。通过北京台网部分台站噪声功率谱与含有气枪信号信息的噪声功率谱进行的比较，发现频率0．2Hz左右含气枪信号信息的噪声功率谱明显高于不含气枪信号信息噪声功率谱。

| Abstract: | The data recorded in Beijing Seismic Network was analyzed to find the signals caused by the air gun test in Bohai sea area carried by the survey department of China National Offshore Oil Corporation, using the power spectrum method. Through comparison between power spectrum densities of noise and the noise with air gun test information among several stations, we found that the power spectrum density of noise with air gun test was higher than that without air gun test at around 0.2 Hz. |
