4Comparison of eastern paleo-Tethyan ophiolites and its geodynamic significance--Evidence from Dur'ngoi ophiolite显示文摘Nd-Pb isotopic geochemistry of metabasalt from Dur抧goi ophiolite, Qinghai Prov-ince, NW China reveals the presence of DMM mixing with EMII components in its upper mantle source, which is comparable with present Indian MORB. Comparisons indicate that the geo-chemistry, chronology and source characteristics of Dur抧goi ophiolite coincide with Pa-leo-tethyan ophiolites from 揝anjiang?area. Together with evidences from regional geology in adjacent areas, this study proves that independent paleo-tethyan basins evolved contemporarily, the dynamics of which is attributed to the interaction of mantle plume with over-riding lithosphere.CHEN Liang1,2, SUN Yong1,2, PEI Xianzhi2, Feng Tao2 & Zhang Guowei2 1.

7Color 3D Reverse Engineering显示文摘This paper presents a principle and a method of col or 3D laser scanning measurement. Based on the fundamental monochrome 3D measureme nt study, color information capture, color texture mapping, coordinate computati on and other techniques are performed to achieve color 3D measurement. The syste m is designed and composed of a line laser light emitter, one color CCD camera, a motor-driven rotary filter, a circuit card and a computer. Two steps in captu ring object’s images in the measurement process: First, the color CCD camera ta kes the color picture of the object to be used for texture mapping in post proce ssing. Secondly, the monochrome data of the object is taken. The laser light emi tter is started; the light plane and the surface of the object intersect to form an undulate line, which forms an image on the CCD sensor. After the optic- electronics transformation, the electronic signals are captured and send to the computer. A new color 3D measurement model was derived, and a rapid calibra ting method to measure the system parameters was proposed--optical plane equat ion calibrating method. A calibrating drone was designed and built. 3D color sca nning system not only provides an object’s individual point information in the 3D coordinate, in the mean time, it provides the color information of each indiv idual point. This paper also advances a multi-frame auto-merging method, i.e. several frames of color 3D digital images measured are merged quickly according to their curvature characteristics and RGB information. Initial matching and fin e tune of the registration are completely performed by the computer; initial mat ching is via user interface in helping computer to find the transformation matri x. The transformation matrix is found according to the geometric characteristics chosen by hand. After the initial transformation matrix is found, fine tune of the registration is preformed to do the optimum adjustment to achieve a complete color textured 3D model. The system can be broadly used in the fields of produc t design, mold manufacture, multimedia, game development, animation, medical eng ineering, antique digitization, etc.XU Zhi-qin 1, YE Sheng-hua 1, FAN Guang-zhao 2 (1.

8冲击波测量法检验含铝非理想炸药的能量释放(英文)显示文摘将有机玻璃紧贴于炸药柱,当爆轰波沿药柱传播至界面时即在有机玻璃中引起一个强烈的冲击波。利用一特定装置分别测定在NH4NO3/TNT80/20,NH4NO3/TNT/Al80/10/10,NH4NO3/TNT/LiF80/10/10和NH4NO3/Al90/10等炸药爆轰作用下有机玻璃中冲击波的传播速度,以检验含铝非理想炸药的能量释放。结果表明,冲击波速度随着传播距离的增加而降低;铝粉颗粒越细,冲击波衰减速度越慢,这是由于铝的氧化反应热所致。Stanisaw CUDZIO, Andrzej MARANDA, Waldemar Andrzej TRZCI N ’SKI (Military University of Technology Kaliskiego 2,01 489 Warsaw,Poland) 1999含能材料1999,7,1:2
