The composites were similar to natural bone to some extent in crystallite phase composition, crystallite size of hydroxyapatite and micro-structure of collagen fibril.
复合材料的晶相组成，羟基磷灰石晶体大小、胶原纤维的结构等都与天然骨相似。
The results showed that there were distinct differences in micro-fibril Angle, width of growth-ring and tracheid diameter.
结果表明，管胞直径和微纤丝角及生长轮宽度等指标表现为差异显著。
The result shows that:(1)Micro-fibril angle increases gradually from the center to the edge in radial direction, and the surface area percentage of its fiber band has the same variability;
结果表明，微纤丝角径向自内向外略有减小，纤维股面积比径向自内向外逐渐增大；
