Introduction to New Cover Mark of<CT Theory and Applications> and New Earth-mantle Velocity Model
Abstract：In this article, we introduce the New Cover Mark of<CT Theory and Applications>and a new earth-mantle 3-D velocity model. As shown at the lower-left part of the cover of Journal CTTA, our new journal cover-mark, issue No.1, 2002, consists of three parts: the upper part shows a three-dimension triangular four-side view(similar with the stereology imaging mark); The lower-right part denotes a medical imaging scanner(including various X-CT and MRI scanners, etc.); The lower-left part shows the earth-core(red color) and a 3-dimension earth model with two vertical cross-sections of earth-mantle P-wave velocity distribution, which is provided by Prof. Dapeng Zhao, as shown in cover page 4, red and blue colors denote the slow and fast velocities respectively. The velocity perturbation scale is shown below the cross-sections, and its method and data presented in his EPSL paper[1],This paper by Prof. Zhao is very important and has attracted great attention of earth scientists in the world. For details, see the EPSL web site.
