1.Around the Haversian canals, there are concentric lamellae, which look a bit like tree rings.

在斯管周围有许多同心片，看起来有点像树的年轮。

2.In osteoporosis, there's thinning of the cortical bone, widening of the Haversian canals and a decrease in the number of trabeculae in the spongy bone.

疏松症中，皮会变、斯管变宽、松内的小梁数目减少。

3.So with osteoporosis, abnormal findings include fewer trabeculae in the spongy bone and thinning of the cortical bone, as well as the widening of the Haversian canals.

那，疏松的异常包括松中的小梁会减少，皮变，还有斯管变宽。

4.In the center of these osteons, there are hollow spaces called Haversian canals, which contain the blood supply and innervation for the bone cells.

在这些单位的中心，这个中空的部分被称作斯管，提供了为细胞供应血液以及神经支配的空间。

5.It's also dotted with features known as Haversian canals, which are the pathways the blood vessels followed to bring nutrients to the fast-growing tissue.

它也散布着被称为斯运河的特征，这是血管为快速生长的组织带来营养所遵循的途径。机翻
