| 摘 要： | 通过重力异常分解模型，选用小波基函数“bior3.7”，分解得出青藏高原东北缘布格重力异常资料的小波4阶近似成分，利用其主要由莫霍面产生的布格重力异常，以6条人工地震剖面信息做初始控制条件，反演得出青藏高原东北缘的地壳厚度。

| Abstract: | With a gravity anomalies decomposition model,and through using the wavelet function bior3.7,the fourth order wavelet approximate components of the Bouger gravity anomalies of northeast margin of the Qinghai-Tibetan Plateau can be obtained.Furthermore,by utilizing the Bouger gravity anomalies come from the Moho and taking the information from the 6 artificial profiles as the initial control conditions,the crustal thickness of northeastern margin of the Qinghai-Tibetan Plateau is inversed,and the inversion re... |
