| 2. | Take advantage of the checker - board - test method to test the horizontal resolution of velocity and depth parameter on hq - 13 profile and the four profiles of yunnan region
利用检测板试验的方法以及与其它二维和三维成像结果的对比验证了本文成像结果的可靠性。 |
| 3. | The software adopts eofs to describe the sound speed profile in the sea , and takes its bottom depth parameters from inputed digital chart . the software can process more complex 3 - dimension sound field
软件中采用经验正交函数来描述海洋中的声速剖面，海底深度参数以数字海图的形式输入，可以处理较复杂的三维情况下的海洋环境声场。 |
| 4. | During the inversion process of velocity and depth parameter , the velocity parameter should be inversed firstly and then do the depth so as to assure the stability of the final results and the reliability of the solution
在参数反演过程中应采用先反演速度参数、再反演深度参数的方案，这样的步骤使得反演结果较稳定，得到的解更为可信。 |
| 5. | It ' s found that the best absolute lateral resolution of the velocity on the hq - 13 profile is about 30 kilometer , while that of the depth parameter on this profile can be smaller than 10 kilometer . both of the velocity and depth parameter points are of 20 kilometers interval on the four profiles in yunnan region , their lateral resolution are also detected by the checker - board - test method
检测板试验的结果表明， hq - 13线速度地壳速度结构横向变化的最佳绝对分辨应在30km左右，该测线上界面形态横向变化的绝对分辨可以达到10km以内；取速度节点间距和界面深度节点间距均为20km的检测板试验表明，云南地区四条测线地壳内界面形态的横向分辨良好。 |
| 6. | Several numerical experiments are carried out to detect the actual steps and limitation for the velocity and depth parameter ' s ray inversion in the fourth chapter , and the we find that : a . the resolution capability of the layer ' s velocity change along both the top and bottom boundary is very poor . thus generally the vertical homogeneous layer model whose top velocity equal to that of its bottom boundary should be considered
本文的第四章通过一系列模型试验详细探讨了利用射线反演方法反演速度和深度参数的实际步骤，认为走时反演对速度层内顶部和底部速度变化的分辨能力很弱，仅仅依靠走时数据难以反演出层内顶部和底部的速度变化，故一般情况下应采用速度层底部和顶部速度相同的纵向均匀模型。 |
