fusion bomb
Học thuậtThân thiện
Definition
- Noun:
- A thermonuclear weapon: A type of nuclear weapon that derives its immense destructive energy from the fusion (joining together) of atomic nuclei, specifically isotopes of hydrogen (like deuterium and tritium), under conditions of extreme heat and pressure. This process is distinct from and more powerful than the fission process used in early atomic bombs.
Usage
- The term "fusion bomb" is a technical and descriptive term for a hydrogen bomb (H-bomb). It is used in scientific, military, and historical contexts to describe the weapon's operating principle.
- It is often used to distinguish this class of weapon from fission-based atomic bombs.
Examples
- Noun:
- The development of the fusion bomb marked a significant increase in the destructive power of nuclear arsenals.
- Scientists explained that a fusion bomb uses a fission explosion to trigger the main fusion reaction.
Advanced Usage
- The phrase is sometimes used metaphorically to describe a powerful combination or mixture of elements, though this is less common.
- The chef's new dish was a fusion bomb of Asian and Latin American flavors. (Metaphorical use)
Variants and Related Words
- Hydrogen bomb (H-bomb): The more common name for a fusion bomb.
- Thermonuclear weapon: A formal synonym emphasizing the high temperatures required for the fusion reaction.
- Fission bomb: A nuclear weapon based on splitting heavy atomic nuclei, which is typically the first stage used to trigger a fusion bomb.
Synonyms
- Hydrogen bomb
- H-bomb
- Thermonuclear bomb
Notes
- The core mechanism of a fusion bomb involves using the intense heat and pressure from a primary fission explosion to compress and ignite a secondary fusion fuel, causing a much larger explosion. The term precisely describes this secondary, fusion-based stage of the weapon.
Noun
- a nuclear weapon that releases atomic energy by union of light (hydrogen) nuclei at high temperatures to form helium
