摘要 为高精度、快速地完成地面核磁共振信号的正演模拟,借助连分式插值技术对积分核函数利用尽可能少的节点上的值进行插值计算。核函数的积分采用高斯求积公式。对自由空间中单层含水层地面核磁共振响应的数值模拟结果表明,结合插值与高斯积分,能精确、高效地获得地面核磁共振信号。 To simulate surface Nuclear Magnetic Resonance (NMR) signal efficiently and accurately, kernel function can be computed from the known values at certain nodes as few as possible by means of continuous fraction interpolation. Numerical results of a single aquifer embedded into free space show that the combination of Gaussion quadrature and continuous fraction interpolation can speed up surface NMR simulation without losing accuracy.
