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的棉线，只能燃烧四十五小时。

The thready mass was the hair of the head—long and straggling, showing that the head was a woman's.

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

根据磁场的形，极光可以形成色彩斑斓的丝或片。

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

当它们挤入恒星之间的物质时，有些有着明亮的圆轮；其他的则形成复杂的丝网。

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不是用塑料制成的，而是用丝物制成的。

25. For example, the pharmaceutical industry grows filamentous fungi in large quantities in the lab.

举个例子来说，制药行业在实验室中培育了大量的丝。

This filamentous approach to acoustics could someday change the way we make microphones… and take webcasting to a whole new level.

霍普金：这种丝的声方法有朝一日可能会改变我们制造麦克风的方式… … 并将网络广播提升到一个全新的水平。

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的塑料，通过一个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，我们还可以把丝的细胞壁用作过滤器，即使在这些死后。

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.

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

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。

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，云层消退成网的暗淡丝物并消失，天空清澈明亮，每一个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.

构成草皮的最有影响力的草是一种精致的 calamagrostis，它有细密的丝叶子和松散、通风的圆锥花序，它们似乎像紫色的雾气一样漂浮在繁花似锦的草坪上。

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.

细丝的尘雾也排列在星臂上，中央的凸起物或条物发出怪异的红黄色，那里的恒星形成活动早就停止了，更蓝的恒星都爆炸了，只留下更红的恒星。

Here you find mats of the curious dwarf willow scarce an inch high, yet sending up a multitude of gray silky catkins, illumined here and there with, the purple cups and bells of bryanthus and vaccinium.

在这里，你会发现稀奇古怪的矮柳的垫子不到一英寸高，却长出大量灰色的丝柔荑花序，点缀着紫花和越橘的紫色杯和铃花序。
