你要做的就是拿一些长丝状的塑料，通过一个非常非常热的喷嘴把它挤出。

Filigrees of dust clouds align with the arms as well, and the central bulge or bar glows an eerie reddish yellow, the star formation there long since ceased, the bluer stars all exploded, leaving only the redder stars behind.

Each grain on the cob is the starting point for a thread of silk; and, unless the thread receives some particle of the dust which falls from the tassel flowers, the kernel with which it is connected will not grow.

玉上的每一个颗粒都是一束丝状雌花的起点，除非花束获得来自于状雄花的微粒，否则它所连接的内核就无法成长。

It's an expanding cloud of gas and dust, the remains of that dying star, and the colours are different chemical elements, so the orange is hydrogen, the red is nitrogen and those filaments of green are oxygen.

这个由气和尘埃组成的星云还在断扩张，它是一颗垂死恒星的残骸，同的颜色代表同的化学元素，橙色表示氢元素，红色是氮元素，那些绿色的丝状物是氧元素。

They're in this in between area. So if you cut them for example and you pull them apart, you might see like these stringy pieces, or like almost like liquid, these weird like almost like fibers.

介于固和液。如果你把它们切开，然后把它们拉开，你可能会看到像丝状的碎片，或者几乎像液一样，奇怪的几乎像纤维的东西。

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.

鸟类羽毛的前身是竖直、密集的丝状结构，主要由角蛋白构成，与构成你的头发和指甲的东西是同样的物质。

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.

中国出土的化石表明羽毛的前身呈简易的丝状结构，可能具有隔离热量的功用，这些简易丝状羽毛在陆地恐龙身上断进化，直至后来才具备了飞行功能。

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。

The first lamp that he made had a cotton thread for a filament, and it could burn for only forty-five hours.

他制造的第一盏灯中是一根细丝状的棉线，只能燃烧四十五小时。

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

这是牙线。但是它和牙膏筒最大的区别是它是用塑料制成的，而是用丝状物制成的。

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.

而在我们身的某些部分，动作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。

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。

Depending on the shape of the magnetic field, the auroras can form spectacular multicolored ribbons and sheets.

根据磁场的形状，极光可以形成色彩斑斓的丝状或片状。

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。

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

当它们挤入恒星的物质时，有些有着明亮的圆轮；其他的则形成复杂的丝状网。

So now we're going to julienne, very finely slice the pumpkin skins.

所以现在我们要将南瓜皮切成非常细的丝状。

It's been found with preserved quill-like filaments growing from its tail.

它被发现尾部长有保存完好的类似羽毛的丝状物。

Like those stringy things I sometimes find in my orange juice?

就像我有时在橙汁里发现的那种丝状物？

Inside the body, all of the silk glands have liquid protein in them.

在内, 所有的丝状腺都有液态蛋白质。

Have a close-up look at the nucleus though, what is this weird filamentary structure?

仔细看看细胞核，这个奇怪的丝状结构是什么？
