Water proton transverse relaxation times (T2) and self-diffusion coefficients (D) were measured in randomly oriented hydrated collagen fibers. Three T2 relaxation times were discerned indicating the presence of at least three water fractions in the collagen sample. The D values associated with each water fraction were determined. The diffusion time dependence of D suggests water motion is restricted by macromolecular structure. The experimental results are discussed with reference to the structural properties of hydrated collagen fibers.
在随机取向的水合胶原纤维中测量了水质子横向弛豫时间（T2）和自扩散系数（D）。辨别出三个T2弛豫时间，表明胶原样品中至少存在三种水分级分。确定了与每种水分级分相关的D值。D对扩散时间的依赖性表明水的运动受到大分子结构的限制。结合水合胶原纤维的结构特性对实验结果进行了讨论。
