Forward modeling is the base of inversion techniques, and the speed of forward modeling and how to store the coefficient matrix from inversion are the key techniques of the gravity and magnetic 3D inversion. An new Gravity and Magnetic 3D forward modeling method with rolling topography is presented in this paper. The principle is that two different scale matrixes with different measurements from forwarding modeling are produced based on the layers partition for inversion vertically, and the forward modeling values of the gravity and magnetic value with rolling topography are direcdy computed based on the local linear interpolating by taking the topography as the horizontal in the local model space. 相似文献

2D INVERSION OF VES DATA UNDER ROLLING TOPOGRAPHY AND ITS APPLICATION
Considering to meet usually the rolling topogra- phy in the groundwater resource investigation, mineral exploration, engineering detection, etc. and based on the published literature in existence, this paper pres- ent our settlement of 2D inversion problem of VES da- m with the rolling topography by applying the total smooth constraint in the inversion. The approach can effectively process the FEM grid division and the in version software is made. Finally, it is proved that the inverted results is reliable through inverting the simulated and measured VES data, and the inversion software can be applied to the practical work. 相似文献

<正>Fourteen graptolite species of the Late Tremadoc and Early Floian are described from the Nanba section in the Yiyang area,Hunan Province.Among them,Paradelograptus onubensis, Kiaerograptus bulmani,K.kutchini and Paratemnograptus isolatus of the Late Tremadoc are first found in China.Based on the current graptolite materials,the correspondingly complete graptolite zones of Upper Tremadocian in China are recognized as follows(in ascending order):the Adelograptus tenellus Zone,the Aorograptus victoriae Zone,the Araneograptus murrayi Zone and the Hunnegraptus copiosus Zone.In the Nanba section,the Hunnegraptus copiosus Zone is overlain directly by the Tetragraptus approximatus Zone,there is no hiatus below the base of Floian. 相似文献

<正>A new family of so-called‘higher' planthoppers,Weiwoboidae fam.nov.,from the Lower Eocene of Yunnan is described.A new monotypic genus,Weiwoboa gen.nov.,with Weiwoboa meridiana sp.nov.is also described and illustrated.The characters of tegmen venation of the new family,its evolution,and supposed relationships are briefly discussed. 相似文献
