underground geology meaning in Chinese
地下地质学
Examples
- However , for the seismic data from the low snr region with complex surface , because of the complicated surface and underground geology conditions and the poor transmitting / receiving conditions , there exist severe static correction problem and strong disturbance in the original records so that the effective reflected waves can not be identified in the records , the snr in the original records is low and the static correction problem is severe
复杂地表低信噪比地区地震资料,由于地表及地下地质条件复杂,激发及接收条件差,在原始采集记录上存在着严重的静校正问题及各类强干扰,记录上几乎看不到有效反射波的影子,原始资料信噪比低,静校正问题突出。 - Owing to complicated earth ' s surface condition such as the steep stratum outcropping of front - zone of mountain or the huge thick gravel stratum ' s overlay and earth ' s surface large undulation , complicated underground geology structure developed extremely such as thrust and overthrust nappe , and violent change of the lateral velocity , etc . in front - zone of mountain there are a series of problems such as serious secondary disturbance and low signal - to - noise ratio in seismic exploration gathering
由于山前带高陡岩层出露或巨厚砾石层的覆盖、地表起伏大等复杂的地表条件、逆冲和逆掩推覆等复杂地下地质构造发育、速度横向变化剧烈等原因,造成了山前带地震勘探资料采集存在次生干扰严重和信噪比低等一系列问题。
