利用核磁共振成像技术测量了泡沫的三维结构，并对其三维几何特性进行了分析。利用新开发的三维几何结构分析程序，从三维核磁共振图像数据中提取了聚氨酯泡沫试样的8个气泡多面体，并首次对真实的泡沫体系进行了定量几何数据测量。结果与Matzke的肥皂泡研究结果一致，但与Weaire和Weilan的三维空间划分为具有最小分割面积的等体积细胞的最佳解不一致。这种分歧的原因尚不清楚;然而，改进的泡沫制备和更系统的测量使用的方法在这里开发可能会澄清这种差异。(C)出版社：Academic Press，Inc.
Three-dimensional foam structures were measured using NMR imaging, and their 3D geometrical properties were analyzed. Eight bubble polyhedra of a polyurethane foam specimen were extracted from 3D NMR image data using a newly developed 3D geometrical structure analysis program, and quantitative geometrical data were measured for the first time for real foam systems. The results agreed well with the study by Matzke with soap bubbles but did not agree with the optimum solution by Weaire and Phelan for 3D space division into equal volume cells with minimum partitional area. The reason for this disagreement is not clear; however, improved foam preparation and more systematic measurements using the method developed here may clarify this difference.
