| 6. | The method can be used to compute large residual static corrections in complex 3d near - surface areas such as areas covered by desert and gebi . 5 ) based on 2d refraction statics method in cmp domain , 3d refraction static method of cmp domain is presented 该方法是在二维基础上发展的,在折射界面起伏不大的情况下,它可以同时解决三维cmp道集中长波长静校正和短波长静校正问题,可适用于塔里木沙漠、长庆黄土塬覆盖区。 |
| 7. | But the conflict between them was appeared during our research in field and the discussion with others . it is followed that the former with the rolling bedrock , the mid with mild bedrock and the latter with the stable bedrock relatively . the conflict between two conclusion above arise , what relationship between loess landforms and their bedrock exist 但在野外调查及同其他学者交流中发现两者并非总体对应一致,显示出陕北黄土高原南部黄土塬基底起伏相对较大,北部黄土梁状(为主)丘陵沟壑区及黄土峁状(为主)丘陵沟壑区基底相对平坦的特征。 |
| 8. | Inversion of the near surface structure can be done by the method with refraction first - break information , so it can be used to solve 2d long wavelength and short wavelength statics problems for complex near surface areas ; 4 ) a kind of 3d statics method with statistical deposition of refraction first - break traveling time in common shot domain is developed 它适应折射面起伏不大、折射层较稳定的近地表条件,利用该方法可以解决二维沙漠、黄土塬覆盖区等复杂地表条件的长短波长静校正问题; ( 4 )三维共炮域折射旅行时统计分解静校正方法。 |
| 9. | There is a evolutional phenomenon to have been recognized in shaanbei loess plateau from south to north . that is luochuan district with the loess yuan ( platform land ) in south . yan ' an - an ' sai district with the loess liang ( ridges ) mainly in middle and shunde - mizhi district with the loess mao ( rounded knolls ) mainly in north . this frame and tendency is got and thought to coincide with the styles of their bedrock traditionalh ? called conformability 在长期的研究和调查过程中,发现陕北黄土高原在南北纵向上存在明显的黄土地貌分异现象,即由南向北,大致依次为洛川黄土塬(广义)地貌、延安?安塞黄土梁状(为主)丘陵沟壑地貌、绥德?子洲黄土峁状(为主)沟壑地貌。 |
