When these grasp on to the hooklets of neighboring barbules, they create a structural network.
当它们抓住邻近小枝的钩状物时，就形成了一个结构网络。
The finding suggests that the barbs and barbules evolved before the rachis in feathers.
该发现表明，羽毛中的羽枝和小羽枝是先于羽轴进化出来的。
But this specimen lacked the rachis; it just had barbs and barbules down its ribbonlike tail.
但这件标本没有羽轴，带状尾巴上只有羽枝和小羽枝。
One of the minute, hooked projections extending from and interlocking the barbules of a feather.
羽纤支从一根羽毛的羽小支上延伸或与羽小支交叉的…
When these grasp on to the hooklets of neighboring barbules, they create a structural network that's featherlight but remarkably strong.
当这些小钩子与邻近羽刺上的类似结构结合在一起后，便形成了羽毛的结构网络，看似轻柔，但又异常牢固。
Branching from the rachis are smaller shafts called barbs, and then branching from the barbs are even smaller filaments called barbules.
沿着羽轴伸展开去的较小的杆状物叫做羽枝，沿着羽枝伸展开去的更小的细丝则叫小羽枝。
According to this scenario, scales became feathers by first elongating, then growing fringed edges, and finally producing hooked and grooved barbules.
根据传统理论，鳞片变成羽毛的第一步是先拉长，接著长出流苏般的边缘，最后产生有小钩与沟槽的羽小枝。
Structure characterization and spectrum investigation suggest that the iridescent color of the green and purple barbules should originate from the interference from the top keratin cortex layer.
