Definition

Noun: - Hydrogen bomb, H-bomb: A thermonuclear weapon of immense destructive power. Its energy is released through the nuclear fusion of hydrogen isotopes, a process that can be initiated by a primary fission (atomic bomb) stage. Its explosive yield is typically hundreds to thousands of times greater than that of an atomic (fission) bomb.

Usage Examples

• Noun:
  • Bom khinh khí có sức hủy diệt khủng khiếp. (The hydrogen bomb has terrifying destructive power.)
  • Quốc gia đó đã thử nghiệm một quả bom khinh khí. (That country tested a hydrogen bomb.)
  • Sức công phá của bom khinh khí lớn hơn bom nguyên tử rất nhiều lần. (The destructive force of a hydrogen bomb is many times greater than that of an atomic bomb.)

Advanced Usage

• The term is used in scientific, military, and political contexts to discuss nuclear arsenals, deterrence theory, and historical events like nuclear testing.
• It is often contrasted with "bom nguyên tử" (atomic bomb), which is a fission-based weapon.

Variants and Related Words

• Bom H (n): Abbreviation for "bom khinh khí"; synonymous with hydrogen bomb.
  • Hiệp ước cấm thử bom H đã được ký kết. (A treaty banning H-bomb tests was signed.)
• Bom nhiệt hạch (n): The technical/scientific term for a thermonuclear bomb, which is the same device as a hydrogen bomb.
• Bom nguyên tử (n): Atomic bomb; a fission bomb, which is less powerful and often serves as the trigger for a hydrogen bomb.

Synonyms

• Thermonuclear weapon: The broader technical category for weapons using fusion reactions.
• H-bomb: Common abbreviation.
