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

在哈弗斯管周围有许多同心薄片，看有点像树的年轮。

What we see here is the beginning of dense haversian bone.

我们在这里看到的是致密哈佛的开始。

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.

质疏松症中，皮质会变薄、哈弗斯管变宽、松质内的数目减少。

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.

那么，质疏松的异常包括松质中的会减少，皮质变薄，还有哈弗斯管变宽。

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.

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

We know we begin with calcified cartilage that will form into primary bone and then mature into secondary bone and then eventually develop into something called dense haversian bone.

我们知道我们从钙化软开始，它会形成初级，然后成熟为次级，最后发展成一种叫做致密哈弗斯的东西。
