摘要
Three-dimensional (3-D) nuclear magnetic resonance (NMR) experiments reflect material structure, such as physical array of porous media and chemical compositions of complex fluids. However, a huge database is acquired in multi-dimensional NMR and obstructs the extraction of this information in a proper manner. In this paper, a new fast 3-D Laplace inversion procedure is introduced which contains a specially designed 3-D pulse sequence to acquire the data responding to interesting NMR properties simultaneously and efficient data-processing algorithm referring this pulse sequence. A 3-D NMR experiment in low-field on water-saturated synthetic porous sample is presented to demonstrate the validity of the designed 3-D inverse Laplace algorithm.
