網絡擴展資料

cosmic radiation（宇宙輻射）指來自宇宙空間的高能輻射，主要由帶電粒子（如質子、電子）和電磁波組成。以下是詳細解釋：

定義與組成
- 核心含義：宇宙輻射是源自地球大氣層外的輻射，包括初級宇宙射線（如高能質子、原子核）和次級宇宙射線（初級射線與大氣分子碰撞後産生的粒子，如介子、中子等）。
- 能量來源：主要産生于超新星爆炸、黑洞活動等極端天體物理現象，部分來自太陽活動（如太陽耀斑）。
特點與影響
- 高能性：粒子能量極高，可達地球實驗室加速器無法達到的水平。
- 對地球的影響：大部分被大氣層吸收，但仍有少量到達地表，可能影響電子設備、生物DNA，甚至航空機組人員的輻射暴露。
相關術語
- Cosmic radiation age（宇宙線輻射年代）：指通過宇宙射線與物質作用産生的同位素（如碳-14）來測定地質或考古樣本年齡的方法。
- 電磁輻射（electromagnetic radiation）：與宇宙輻射中的光子部分（如X射線、伽馬射線）相關。
應用領域
- 科學研究：用于研究宇宙起源、粒子物理特性等。
- 技術影響：可能幹擾衛星通信和航天器電子系統，需特殊防護設計。

如需更深入的物理學機制或防護措施，可參考天文學或輻射防護領域的專業資料。

Cosmic radiation, also known as cosmic rays, refers to the high-energy particles that originate from outside the Earth's atmosphere and bombard the Earth's surface. Here is a detailed explanation of this term.

Definition and Usage

Cosmic radiation refers to the radiation that comes from outer space and reaches the Earth. It is composed of high-energy particles, such as protons, alpha particles, and even heavier atomic nuclei. Cosmic radiation is constantly bombarding the Earth's atmosphere and surface, and is one of the sources of natural background radiation.

Example Sentences

Cosmic radiation is a major concern for astronauts on long space missions. (太空飛行員在長時間的太空任務中，宇宙輻射是一個主要的問題。)
The study of cosmic radiation has led to a better understanding of the structure and evolution of the universe. (對宇宙輻射的研究，使人們對宇宙的結構和演化有了更好的認識。)

Usage and Synonyms

Cosmic radiation is often used in scientific and technical contexts, such as astrophysics, space exploration, and radiation protection. It is also known as cosmic rays, although this term is somewhat of a misnomer, as cosmic radiation includes particles other than just rays. Other related terms include ionizing radiation, which refers to any radiation that can remove tightly bound electrons from atoms, and non-ionizing radiation, which refers to radiation that does not have enough energy to ionize atoms but can still cause biological effects.

Antonyms

There is no direct antonym for cosmic radiation, as it is a specific type of radiation. However, one could refer to "terrestrial radiation" or "background radiation" to describe the radiation that originates from the Earth's surface and environment.
