| 摘 要： | 本文以实验为基础,论述了玄武岩释放封闭氢的超声机理。在超声作用下释放的封闭氢,只有少部分逸散,可做为氢前兆信息,而大部分则转化为吸附氢,但依然是氢前兆的物质基础。此外,还阐述了只根据氢析出量不能判断声发射强度,从而推测岩石主破裂强度,即地震强弱

EXPERIMENTAL STUDY ON THE RELEASE OF SEALED H2 FROM BASALT ROCK UNDER ULTRASONIC VIBRATION |
| |
| Abstract: | This paper discusses ultrasonic mechanism of the sealed-H2 release from basalt rock on the basis of experiments.A small amount of released H2 by ultrasonic vibration is escaping H2,whereas most H2 is absorbed H2.Both phenomena can be regarded as a precursory H2.So,it is possible to use H2.to.forcast earthquake.Seeing that the intensity of u.v.and the its duration were constant in the experiments and the amount of released H2 gas increased during each vibration,abnormal H2 seems not to be representative of accoustic emission intensity,thus suggesting that the intensity of the failure of rock may be representative of the earthquake magnitude |
