hypersonic [noun]
hypersonic 常作定语修饰 speed、flight、missile 等名词。
The new fighter jet can reach hypersonic speeds.
这种新型战斗机可以达到高超声速。
高超声速的；极超音速的
先理解核心含义，再看它在真实句子里的用法。
高超声速的；极超音速的
of or relating to hypersonic speed; moving at hypersonic speed
The new fighter jet can reach hypersonic speeds.
这种新型战斗机可以达到高超声速。
速度等于或大于声速五倍,或能达到该速度的。
Of a speed, equal to, or greater than, or capable of achieving, five times the speed of sound.
速度远高于声速,以致因空气的化学反应或离解而产生显著行为差异的。
Of a speed, far enough above the speed of sound as to cause significant differences in behaviour due to chemical reactions or dissociation of the air.
The new experimental jet is designed for hypersonic flight.
这架新的实验性喷气式飞机是为高超声速飞行而设计的。
Engineers are testing materials that can survive hypersonic speeds.
工程师们正在测试能够承受高超声速速度的材料。
The company hopes to build a hypersonic passenger plane one day.
这家公司希望有朝一日建造一架高超声速客机。
hypersonic 常作定语修饰 speed、flight、missile 等名词。
The new fighter jet can reach hypersonic speeds.
这种新型战斗机可以达到高超声速。
The missile is hypersonic, traveling at over Mach 5.
这种导弹是高超声速的，飞行速度超过5马赫。
Not this
The new fighter can fly at supersonic speeds of Mach 6.
Use this
The new fighter can fly at hypersonic speeds of Mach 6.
supersonic 指超过音速（通常1–5马赫），而 hypersonic 指高超声速（5马赫以上）。表示6马赫时应使用 hypersonic，不能把二者混用。
Not this
Hypersonic is difficult to study in a wind tunnel.
Use this
Hypersonic flow is difficult to study in a wind tunnel.
hypersonic 是形容词，不能单独作主语；应后接被修饰的名词（如 flow, flight, missile）来表达“高超声速现象/飞行器”。

高超声速飞行需要先进的热防护系统。
高超声速导弹
Several countries are developing hypersonic missiles.
多个国家正在研发高超声速导弹。
高超声速飞行器
Engineers tested a new hypersonic vehicle in the desert.
工程师在沙漠中测试了一种新型高超声速飞行器。
高超声速风洞
The design was evaluated in a hypersonic wind tunnel.
该设计在高超声速风洞中进行了评估。
高超声速滑翔飞行器
A hypersonic glide vehicle can maneuver after reentry.
高超声速滑翔飞行器可在再入大气层后进行机动。

拆开看：hyper（超级）+ sonic（音速）→ 比音速还快很多，记住“超级音速”就是高超音速。
语域：formal 常见场景：航空工程、航天技术、军事防务 该词多用于正式的科技、工程或军事语境，表示速度超过5倍音速；日常口语中很少使用。
这些 -sonic 结尾的词重音都在 -son-，读作 /ˈsɒnɪk/，与 hypersonic 押韵。注意 hypersonic 的 hyper- 读 /ˌhaɪpə-/，别与 hypertonic /ˌhaɪpəˈtɒnɪk/（高渗的）混淆——它虽形似，但 -tonic 读 /tɒnɪk/，发音不同。
