摘要：With the continuous development of full tensor gradiometer （FTG） measurement techniques, three-dimensional （3D） inversion of FTG data is becoming increasingly used in oil and gas exploration. In the fast processing and interpretation of large-scale high-precision data, the use of the graphics processing unit process unit （GPU） and preconditioning methods are very important in the data inversion. In this paper, an improved preconditioned conjugate gradient algorithm is proposed by combining the symmetric successive over-relaxation （SSOR） technique and the incomplete Choleksy decomposition conjugate gradient algorithm （ICCG）. Since preparing the preconditioner requires extra time, a parallel implement based on GPU is proposed. The improved method is then applied in the inversion of noise- contaminated synthetic data to prove its adaptability in the inversion of 3D FTG data. Results show that the parallel SSOR-ICCG algorithm based on NVIDIA Tesla C2050 GPU achieves a speedup of approximately 25 times that of a serial program using a 2.0 GHz Central Processing Unit （CPU）. Real airbome gravity-gradiometry data from Vinton salt dome （south- west Louisiana, USA） are also considered. Good results are obtained, which verifies the efficiency and feasibility of the proposed parallel method in fast inversion of 3D FTG data.

摘要：孔子原典和谐理论中,涉及关于社会和谐的理想、人际和谐的标准、秩序和谐的尺度、教育和谐的模式、人格和谐的要求、天人和谐的原则等。这些原典和谐思想固然产生于以礼制为本的王权社会,但其中仍然存在着不为特定时代和社会形态所限制的恒常价值。这种关于人作为本体存在的价值体认,可以为我们在树立科学世界观,构建社会主义和谐社会的过程中,达到人与社会和谐、个人身心和谐、人与自然和谐提供难能可贵的生态智慧和思想资源。
