    摘要： A method for performing magnetic resonance spectroscopy on solid samples containing nuclei of interest with spin quantum number I subjects the sample to a static magnetic field. The sample is spun at the magic angle and broad-band excitation of transverse magnetization of the nuclei of interest is effected by applying a first train of rotor-synchronized rf-pulses, having a carrier frequency, to the nuclei of interest with a pulse duration 0.1 μs 1. Uniform excitation of a great number of spinning sidebands or families of sidebands that arise from large first-order quadrupole or hyperfine interactions is enabled and signal intensity is thereby improved.

    摘要： The method for a hydrocarbon mixture composition determination includes the collection of at least one sample of the hydrocarbon mixture. For this sample, a nuclear magnetic resonance method is used for measuring series of hydrocarbon mixture's free inductance decrement curves within a temperature range of −150° C. to +150°. Each free inductance decrement curve is then used to determine the solid component fraction Ps in the NMR 1H signal at a temperature, at which this value was measured. The received values are then used to plot a temperature dependence of the solid component fraction Ps in the NMR 1H signal and, based on the Ps value variation (ΔPsi), caused by a phase transition of the ith component due to a heating or cooling process and the content of solid and/or liquid phase components in the hydrocarbon mixture is defined by attributing the ΔPsi value to the associated components of the mixture.

    摘要： A method using nuclear magnetic resonance techniques to detect corrosion within metallic structures such as aluminum under non-ferromagnetic coatings without first having to remove the coatings. The metallic structure is placed within an external static magnetic field. A series of radio frequency preparation and inspection pulses is applied to the metallic with the preparation pulses, and for generating a series of nuclear magnetic resonance response signals with the inspection pulses. The response signals are detected and the amplitudes of the response signals are compared with the spin--spin relaxation time of corrosion for detecting the presence of corrosion in the structure.

    摘要： A whole measurement process includes a plurality of step combinations. Each of the step combinations is composed of a solution-state measurement step and a solid-state measurement step. In the solution-state measurement step, solution-state NMR measurement is performed such that magnetization that is to be used in the solid-state measurement step remains. In the solid-state measurement step, solid-state NMR measurement is performed by using the magnetization that remains. No waiting time for recovering magnetization is provided between the solution-state measurement step and the solid-state measurement step. The solid-state measurement step may be performed earlier, and the solution-state measurement step may be performed later. Alternatively, the two steps may be performed simultaneously.
