讨论了一种新型核磁共振设备，核磁共振鼠标（移动通用表面探测器），用于表征聚合物。弹性体的不同性能与有效的横向松弛参数T-2eff有关。多回波序列影响衰减曲线，可以用B-0不均匀性和自旋锁效应来描述。此外，在非均匀磁场条件下，通过对稳态自由进动（SSFP）脉冲序列进行改进，可以提高信号的信噪比。(C) 1998学术出版社。
Applications are discussed of a novel NMR device, the NMR MOUSE (mobile universal surface explorer), for characterization of polymers. Different properties of elastomers can be related to an effective transverse relaxation parameter T-2eff. Effects of multiecho sequences influence the decay curve and can be described in terms of B-0 inhomogeneity and spin-lock effects. Furthermore, the signal-to-noise ratio (SIN) can be improved by use of steady-state free precession (SSFP) pulse sequences modified for use in inhomogeneous magnetic fields. (C) 1998 Academic Press.
