Abstract
Neutron diffraction measurements of the orientation of the apatite crystals show a significant preference of their c-axes for the vertical direction. This preference increases from bottom to top of each vertebral body and is substantially greater for the second than for the fifth lumbar vertebrae. This is in line with the predominantly vertical forces which the former withstands.
摘要
对磷灰石晶体取向的中子衍射测量表明，其c轴显著倾向于垂直方向。这种倾向从每个椎体的底部到顶部逐渐增加，并且第二腰椎的这种倾向比第五腰椎大得多。这与前者承受的主要垂直力是一致的。
