The result shows that large airgun source excited in reservoir environment is rich in low frequencies (0 Hz), and is effective to produce waves with long-offset and deep crustal penetration.

试验结果表明，大容量气枪震源是具有丰富的10Hz以下低频信号的低频震源，其激发的地震波具有传播距离远，穿透深度深的特点。

A field experiment using large volume airgun source was conducted in an onshore reservoir. The characteristics of the waveform and its propogation has been studied.

利用大容量气枪震源在陆上水库进行地震波激发试验，研究陆上水库环境下激发气枪震源所产生的地震波特征及传播距离。

This project also compared and discussed the research results of OBS and onshore-offshore experiments in nearby areas. The conclusion is that the active airgun source is equivalent to an earthquake of about magnitude 0.5, and the airgun signals can be detected at the maximum distance of only about 250 km, which is not enough for the study of deeper lithospheric structure below the crust. Furthermore, the onboard airgun source and MCS streamer are difficult to operate in the shallow water of reef and island areas.

本项目还分析对比了周边地区海底地震仪探测和海陆联合地震探测的研究成果，发现人工气枪震源约相当于0.5级的天然地震，其信号传播距离最远只有250 km左右，很难探测到地壳以下更深部的岩石圈结构特征，此外船载的气枪震源和多道电缆在岛礁区和浅水区很难开展工作。

Some stations do not broadcast over the public airwaves so they do not have to follow F.C.C.
