Some have bright rims as they push into material between the stars; others form complex webs of filaments.

This is dental floss. But the big difference is it's made out of silk instead of plastic.

And what you do is you take some plastic in the form of a filament, and you extrude it through a very, very hot nozzle.

你要做的就是拿一些长丝状的塑料，通过一非常非常热的喷嘴把它挤出。

24. In fact, we can actually use the cell walls of filamentous fungi as a filter, even after the fungi are dead.

事实上，我们还可以把丝状真的细胞壁用作过滤器，即使在这些真死后。

The thread-like fibers we see — thinner than a human hair — are the remains of those dense, dried out walls of cellulose.

我们看到的丝状纤维（比人类毛发还要细）是那些紧实干燥的纤维素壁（原细胞壁）的残留物。

The top picture shows similar filaments discovered by Dr McKellar and his team, suggesting flightless dinosaurs sporting such protofeathers were still around in the late Cretaceous.

上图所示为麦凯乐博士及其研究小组发现的类似丝状的羽毛，表明长有这些原生羽毛的“非鸟”恐龙在白垩纪后期仍然存活着。

Because the substance is composed of mucus and reinforced with numerous superfine and strong silk-like fibers, the slime is incredibly soft yet tough.

这是因为该物质是由黏液组成的，并以无数超细和强有力的丝状纤维加固，因此这种黏液非常柔软，但又非常坚韧。

But fossils from China suggest the precursors of feathers-simple, filament-like structures possibly used for insulation-evolved in land-lubbing dinosaurs and were only later adapted for flight.

The precursors of bird feathers were straight, dense, filament-like structures, which were mostly made of keratin, the same stuff your hair and fingernails are made of.

Some of the only parts of the body whose motions aren't governed by the muscular system are sperm cells, the hair-like cilia in our airways, and certain white blood cells.

而在我们身体的某些部分，动作不是由肌肉系统控制的，它们包括精细胞，我们气道里的丝状纤维，还有某些白细胞。

In a few minutes the cloud withers to a mesh of dim filaments and disappears, leaving the sky perfectly clear and bright, every dust-particle wiped and washed out of it.

几分钟后，云层消退成网状的暗淡丝状物并消失，天空清澈明亮，每一尘埃颗粒都被擦去和冲刷掉。

But since dinosaurs in different times and places had a variety of protofeather types, paleontologists are able to piece together how feathers went from basic filament structures, to ones that allowed flight.

但由于不同时代和地点的恐龙有多种原始羽毛类型，古生物家能够拼凑出羽毛是如何从基本的丝状结构发展为可以飞行的结构的。

The most influential of the grasses composing the sod is a delicate calamagrostis with fine filiform leaves, and loose, airy panicles that seem to float above the flowery lawn like a purple mist.
