There are two types ofrelaxation: longitudinal relaxation, which is the time (T1) needed to align protons in a static magnetic field;
有两种类型的驰豫:纵向驰豫,静磁场中质子定向排列所需的时间T1;

The result shows that sag resistances of the tubing resins have a close relationship with NMR relaxation properties. Resins with longer longitudinal relaxation time possess better sag resistances.
