A road car that can actually lift off the ground, even for a few seconds?
一辆真正能离开地面,哪怕几秒钟的公路汽车?
When people first read those headlines, many assumed it was special effects or pure science fiction.
当人们第一次读到这些头条新闻时,许多人认为那是特效或纯粹的科幻小说。
What kind of hardware is actually making this happen?
到底是什么样的硬件在让这一切发生?
The vehicle utilizes an optional package developed in collaboration with commercial aerospace
该车利用了与商业航空航天公司合作开发的选配套件
engineers, featuring what are known as cold gas thrusters.
工程师,其特点是被称为冷气推进器的东西。
Cold gas thrusters.
冷气推进器。
That is a fascinating aerospace term for our English learners.
对于我们的英语学习者来说,这是一个非常迷人的航空航天术语。
Ethan, could you break down how a cold gas thruster differs from a traditional rocket engine that
伊森,你能解释一下冷气推进器与传统的喷射火焰的火箭发动机有何不同吗?
shoots out flames?
射出火焰?
Of course.
当然。
Think of a standard rocket engine like a giant campfire in a metal tube.
把一个标准的火箭发动机想象成金属管里的巨大营火。
It burns chemical fuels and oxidizers at thousands of degrees to generate blazing exhaust.
它在数千度的高温下燃烧化学燃料和氧化剂,产生炽热的废气。
In contrast, a cold gas thruster involves zero combustion.
相比之下,冷气推进器涉及零燃烧。
Imagine blowing up a sturdy rubber balloon and then letting go of the neck.
想象一下,吹起一个坚固的橡胶气球,然后松开气球口。
The compressed air rushes out through a narrow opening, pushing the balloon across the room.
压缩空气通过狭窄的开口冲出,推动气球飞过房间。
A cold gas thruster takes that exact concept and supercharges it with aerospace precision.
冷气推进器采用了这个确切的概念,并用航空航天精度对其进行了增压。
That balloon metaphor makes it crystal clear.
那个气球隐喻让人一目了然。
So the car stores inert gas, like nitrogen or ultra -dense compressed air, inside heavy composite
所以汽车将惰性气体(如氮气或超致密压缩空气)储存在重型复合材料中。
pressure tanks and releases it through microscopic nozzles at supersonic speeds. Exactly.
压力罐并通过微小的喷嘴以超音速释放它。完全正确。
By firing those downward -facing and rear -facing nozzles, the vehicle can dramatically increase
通过点燃那些朝下和朝后的喷嘴,该车可以显著增加
downward traction on turns, rocket from 0 to 96 kilometers per hour in under two seconds, or release
转弯时的向下牵引力,在不到两秒的时间内从0加速到96公里/小时,或释放
a controlled vertical burst that momentarily lifts the chassis off the tarmac.
一个受控的垂直爆发,瞬间将底盘抬离沥青路面。
The physics behind it is undeniably thrilling.
其背后的物理原理是无可否认地令人兴奋。
However, automotive regulators and industry analysts are already raising practical questions.
然而,汽车监管机构和行业分析师已经提出了实际的问题。
How would street legal safety regulations treat high -pressure gas tanks in pedestrian zones?
街头合法的安全法规将如何对待行人区的髙压储气罐?
And what kind of noise levels does a supersonic airburst produce on regular neighborhood streets?
和超音速空气爆炸在普通居民区街道上会产生什么样的噪音水平?
Those are the exact regulatory hurdles engineers must solve.
这些正是工程师必须解决的确切监管障碍。
Official vehicle reservations have opened internationally, including in China, with earnest deposits

Researchers from the Kunming Institute of Botany under the Chinese Academy of Sciences have
中国科学院昆明植物研究所的研究人员
officially documented an extraordinary wild specimen in Yunnan, a colossal wild mushroom dubbed the
已正式记录了云南的一个非凡的野生标本,这是一朵被称为
king mushroom of Yunnan, or bawang dianjan.
云南的菌王,或者bawang dianjan。
I saw photographs of this organism, and it looks like something straight out of an enchanted fairy tale.

Just how big is this mushroom?
这个蘑菇到底有多大?
The fruiting body stands nearly 50 centimeters tall.
其子实体身高近50厘米。
That is half a meter high and weighs roughly two kilograms.
那是半米高,重约两公斤。
But what has the international scientific community buzzing is not merely its physical dimensions.
但让国际科学界议论纷纷的不仅仅是它的物理尺寸。
Genetic sequencing and morphological analysis confirm that this specimen is not just a newly
基因测序和形态学分析证实,该标本不仅仅是一个新
discovered species.
发现的物种。
It establishes an entirely new biological family, provisionally named Dionjunaceae.
它建立了一个全新的生物科,暂定名为 Dionjunaceae。
An entirely new taxonomic family.
一个全新的分类科。
Let us pause here because that is a vital scientific distinction for our listeners.
让我们在这里停顿一下,因为这对我们的听众来说是一个至关重要的科学区别。
In biological classification, scientists group living things into a hierarchy.
在生物分类中,科学家将生物归入一个层级。
Kingdom, phylum, class, order, family, genus, and species.
界、门、纲、目、科、属、种。
Chloe, how would you help our listeners visualize the difference between finding a new species
克洛伊,你将如何帮助我们的听众形象化理解寻找新物种
versus discovering an entirely new family?
相比发现一个全新的科?
Think of the tree of life like a vast family tree.
把生命之树想象成一颗庞大的家族树。
Discovering a new species is like finding out you have a distant fourth cousin you never knew existed.
发现一个新物种就像发现你有一个从未听说过的远房第四代表亲。
They still sit on an existing small branch.
它们仍然坐在一个现存的小树枝上。
But establishing a brand new biological family is like discovering a massive ancient tree limb that
但建立一个全新的生物科就像发现了一个巨大的古老树枝,
everyone walked past for centuries without ever noticing.
