在随机取向的水合胶原纤维中测量水质子横向弛豫时间（T2）和自扩散系数（D）。识别出三个T2弛豫时间，表明胶原样品中存在至少三种水部分。测定了与每个水部分相关的D值。D的扩散时间依赖性表明水的运动受到大分子结构的限制。实验结果进行了讨论与参考水合胶原纤维的结构特性。
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.
