核物理的用途是什麼?
Knowledge of nuclear physics is essential in many fields in our lives. The most commonly known applications of nuclear physics are nuclear power generation. Modern nuclear physics also contains particle physics, which is taught in close association with nuclear physics. Many of today’s most important advancements in medicine, materials, energy, security, climatology, and dozens of other sciences emanate from the wellspring of basic research and development in nuclear physics.
核物理知識在我們生活的許多領域中都是必不可少的。核物理最常見的已知應用是核能發電。現代核物理還包括粒子物理,它與核物理密切相關。當今在醫學、材料、能源、安全、氣候學和其他幾十門科學領域的許多最重要的進步都源於核物理的基礎研究和發展。

核物理有多難?
What kind of human knowledge is hard, and what kind is not? Nuclear physics isn’t hard to learn. It isn’t that hard if you want to understand the basic reactions like nuclear fusion and fission. Maybe the problem is that you cannot use most of the lessons in everyday life to understand nuclear physics. Mathematics is, and exact physics is better for this purpose. Only this may seem hard.
什麼樣的人類知識是難的,什麼樣的是不難的?核物理學起來不難。如果你想理解核聚變和裂變等基本反應,這並不難。也許問題在於你不能在日常生活中運用大部分的課程來理解核物理。為此目的,數學和精密物理會更加適合。只是這可能看起來很難。

核反應的主要型別有哪些?
Although the number of possible nuclear reactions is enormous, nuclear reactions can be sorted by types:
- Elastic scattering
- Inelastic scattering
- Capture reactions
- Transfer reactions
- Fission reactions
- Fusion reactions
- Spallation reactions
- Nuclear decay
雖然可能的核反應數量是巨大的,但核反應可以按以下型別分類:
- 彈性散射
- 非彈性散射
- 俘獲反應
- 轉移反應
- 裂變反應
- 聚變反應
- 散裂反應
- 核衰變

核反應(nuclear reaction),是指原子核與原子核,或者原子核與各種粒子(如質子,中子,光子或高能電子)之間的相互作用引起的各種變化。在核反應的過程中,會產生不同於入射彈核和靶核的新的原子核。因此,核反應是生成各種不穩定原子核的根本途徑。
