地幔面波 的英文怎麼說
中文拼音 [demànmiànbō]
地幔面波
英文
mantle surface waves-
By using the attenuation property of the rayleigh surface wave to invert the quality factor of crust and upper mantle, this paper yields the s - wave quality factor 3d structure of crust and upper mantle of china, and the viscidity structure of this area as well
本文主要通過rayleigh面波衰減反演地殼上地幔s波品質因子q _ ,建立了中國大陸地殼上地幔s波品質因子全三維結構。探討了中國大陸區域地球內部粘彈性結構。This is of very important significance to understand the material property and geodynamic of corresponding area, the surface wave attenuation mechanism and the inversion algorithm of attenuation and s - wave quality factor are discussed systemically in this paper. some important fruits and understanding are resulted from the the crust and upper mantle tomography of china. ( 1 ) calculating of the rayleigh surface wave attenuation factor y
本文首先探討了面波衰減的機理,對面波衰減和s波品質因子q _反演的計算方法進行了系統的研究,並對中國大陸地區地殼上地幔q _三維結構進行層析成像,取得了以下重要成果: ( 1 ) rayleigh面波衰減系數計算。It shows that the resolution of the crust interface ' s shape on this four profiles is very good, nevertheless that of the velocity structure is relatively poor. the crust and upper mantle ' s fine configuration on the hq - 13 profile is obtained by our tomography, which reveals some important structure and dynamic features of this region : the velocity structure of the crust consists of three layers, the upper crust, the middle crust and the lower crust. however it also can be divided into six lateral blocks, each of them " s velocity is always higher or lower than that of its neighboring blocks
本文第五章利用有限差分反演和射線反演的方法獲得了符離集?奉賢地震測深剖面( hq - 13線)精細的地殼上地幔結構剖面,揭示出下揚子地區一些重要的結構和動力學特徵:地殼速度結構在縱向上大致可分上地殼、中地殼和下地殼三部分,橫向上可劃分為6個塊體,各塊體的p波速度沿測線方向呈現高速?低速?高速的組合。
