摘要
地球是一个巨大的开放系统,地壳放气现象是地壳不同层次进行物质、能量、信息交换的重要形式。因此,强烈放气通道实际上是一个洞察地球内部物理变化、化学变化、应力应变的“窗口”。通过系统观测和记录释放地点、释放量与释放方式可以了解地壳内压力的变化与通道的开启状况,从而可对地震预报、构造活动、火山监测提供重要信息。 断层气测量已经在地震科学领域中广泛应用,并发挥了一定作用。作者全面、系统介绍了此方法在我国的应用现状与初步结果,并指出此方法虽然刚起步,还不够成熟,但由于它轻便、快捷、价廉的优点,已显示了广阔的应用前景与巨大的科学潜力。
The earth is an enormous open system and gas-releasing phenomenon of the crust is the major means of exchanges of matters, energy and information between the deep and the shallow. Therefore a powerful gas-releasing channel is actually a window to understand the subterranean physical and chemical variations as well as stress-strain changes. Release quantities and ways obtained by systematically observing and recording the releasing places can indicate the pressure variations in the crust and openness states of channels,and furthermore provide important information for earthquake prediction,tectonic activities and volcano monitoring.The fracture-gas measurement has been applied widely to seismological sciences and played an important role. The authors introduce systematically the application situations and preliminary achievements in China. They point out that though this technique is at the beginning stage and not much sophisticated , because of its superiorities of easy-carrying, fast-operating and inexpensiveness, it has showed a promising blueprint and great potentialities.
