This invention relates to seismic surveying and in particular relates to an amplifier for reproducing seismic waves. According to our invention9 the input impedance of a seismic wave amplifier is varied inversely as a function of the strength of signals received. By limiting the strength of...收藏...
aThis non-destructive rock reinforcement integrity testing analysis is conducted using a complex “Stress Wave Analysis“ package based on the processing of clear seismic signals imparted into the rock reinforcement element that is being tested. 这非破坏性的岩石增强正直测试的分析使用根据被给予的处理的...
athis assumption is correct for structures standing on a reasonably restricted area, in which the soil characteristics are presumed to be homogeneous and the seismic wave propagating velocity can be neglected 这个假定为站立在一个合理地禁区的结构是正确的,土壤特征被假定是同类的,并且繁殖速度的地波可以被...
UCVM is used to query seismic velocity models for earth properties (Vp, Vs, density) by lat,long, and depth. It can create velocity meshes used in seismic wave propagation simulations. This repo contains the source codes that implement the core UCVM quer
The resultant signal has a residual explosion peak PE' which is highly attenuated in comparison with the resultant implosion peak PI'. The different bubble periods can be achieved by using multiple-muzzle guns fired simultaneously, since the bubble period decreases as the number of muzzles ...
