uranium nucleus 中文意思是什麼
uranium nucleus
解釋
鈾核-
In 1945, all mankind came to know and fear the nucleus when the fission of 1 kg of uranium devastated hiroshima.
1945年，當1公斤的鈾裂變使廣島成為廢墟時，全人類開始知道原子核並對它產生了恐懼。 -
In addition to splitting the nucleus into two halves, the process releases two or more neutrons and a large amount of energy in the form of heat. the released neutrons in turn hit more uranium nuclei and release more neutrons to produce a chain reaction
核裂變過程除了把原子核分裂成兩份外，亦會釋放大量的熱能及同時放出兩個或以上中子，以撞擊更多鈾原子核，再釋放更多中子，產生鏈式裂變反應。 -
When hydrogen is fused to helium, energy is produced. however, we have to supply energy to fuse iron to even heavier elements. this is why we can split a heavy nucleus, like uranium, into several smaller ones to produce energy
氫轉化為氦會產生能量，但要把鐵結合成更重的元素時，卻反而要吸收能量，這也是為甚麼我們把如鈾等重元素分裂成較輕元素時，可以產生能量的原因。 -
Nuclear fission is initiated when the nucleus of a uranium atom is hit by a neutron and split into two halves
鈾原子核被中子撞擊后，會分裂成兩份，產生核裂變。 -
For example, the carbon - 12 nucleus contains 6 protons and 6 neutrons. the uranium - 238 nucleus contains 92 protons and 146 neutrons
例如，碳- 12的原子核內有6顆質子及6顆中子，而鈾- 238的原子核內便有92顆質子及146顆中子。
