地表观测 meaning in Chinese
surface observation
Examples
- A resistivity method with vertical line source has been used to study the distribution of injection water and surplus oil
摘要利用套管供电，通过地表观测电位研究油田注水分布和剩余油分布在油田开发中的应用。 - Watched the event from earth and scientists hoped the cloud of dust and debris would provide clues to the geological composition of the site
很多观测站在地表观测了撞击全过程，科学家希望撞击所激起的尘云和碎石能为研究“卓越湖”区域的地质构成提供依据。 - Observatories watched the event from earth and scientists hoped the cloud of dust and debris would provide clues to the geological composition of the site
很多观测站在地表观测了撞击全过程，科学家希望撞击所激起的尘云和碎石能为研究“卓越湖”区域的地质构成提供依据。 - The forward calculation shown that when providing current through whole casing pipe , the electrical potential on surface is mainly effected by shallow resistivity anomaly , whereas when providing current only at gun perforation position , the electrical potential is on surface mainly effected by corresponding resistivity of gun perforation position
正演结果表明：在全井套管供电时，地表观测电位主要受浅层电阻率不均匀性的影响；在射孔段供电时，地表观测电位主要反映射孔段的电阻率分布。 - Based the basic principle of the accumulation of induced electric charges across the resistivity discontinuities and the induction current channeling inside the conductive bodies inspirited by the mt field , we set up the relation between the measured field on the earth surface and the distribution of the induced source underground by means of the defining the electric charge occurrence probability function and the electric dipole occurrence probability function and the spacial distributing of the " correlation probability " . the " image " of the field sources underground , or the distributing graphy of the induced electric charges and the induced current in the mesuring area can be drawed , from which we can get the outline of the geological anomaly on the meaning of the probability
大地电磁场概率成像方法是一种新的地球物理成像反演方法，它是根据在大电磁波场的激励下，地下介质电阻率间断处产生感应电荷积累和导体内部产生感应电流，从而产生感应电磁场的原理，相应地定义了感应电荷发生概率函数和感应电偶极子发生概率函数，通过“相关概率”发生的大小的空间分布，建立了地表观测场与地下场源空间分布的内在联系。地下场源分布概率的“像” ，即测区的感应电荷和感应电流的概率的分布图像，就是测区内地质体在概率意义下地质异常体的分布轮廓。
