Yiqiang Zhan,Bing Jian,Dewan Maneesh,Xiang Sean Zhouterature. Both high-resolution and low-resolution approaches have been used for PC/QC NMR applications; the latter dominate in popularity for a variety of practical reasons and are usually based on low-field magnets that are not capable of high-resolution performance.

Xiao Dong,Guoyan Zhengof liquid crystals were considered. The analysis of dynamical properties in molecular systems with many degrees of freedom is more complex than that of the equilibrium properties. Spin relaxation characteristics of nuclear spin systems are influenced by internal degrees of freedom within spin-bearininterpose 发表于 2025-3-29 08:12:06

Arthritis of the Spinehe cervical spine, causing neck pain and headache. Cervical spine arthritis also often occurs in children with juvenile idiopathic arthritis. Radiography is an essential diagnostic tool in the evaluation of patients with spinal arthritis, but provides limited information on the posterior spinal stru
