| 摘 要： | 近震体波层析成像方法利用地震波走时来反演地下结构,这需要观测到时准确。在实际情况中,观测到时或多或少包含一定的误差,包括人为误差、仪器误差（如钟差）等。本文提出了一种新的近震体波层析成像方法,来消除随时间积累的误差对反演结果的影响,并验证了该方法的正确性和可行性。 |
| 关 键 词： | 近震体波 层析成像 钟差 |

| Abstract: | Seismic body-wave tomography on the local scale is a technique of imaging 3-D velocity and/or attenuation structure of the Earth,according to minimum principle of difference between theory arrival time and observe arrival time.Hence,the accuracy of observe arrival time is very important to this technique.In practice,observe arrival time include more or less error,such as artificial error,instrumental error,among which some error is a value which increase with increasing of time.The paper propose a new techn... |
