helium nucleus 中文意思是什麼
helium nucleus
解釋
氦核-
The deuteron can fuse with another proton to make a helium 3 nucleus.
氘核可以和另一個質子聚合以生成一個氦3核。 -
Standard theory predicts that two neutrinos are produced for every fusion of four protons into a helium nucleus.
標準理論預言，在由四個質子變成一個氦核的每一次聚變過程中要產生兩個中微子。 -
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。 -
When a star is at the main sequence stage, its interior continuously fuses four hydrogen nuclei i. e. protons into one helium nucleus
在主序星階段，恆星內部不斷把四粒氫原子核即質子融合成一顆氦原子核。 -
Which turns four hydrogen nuclei to a helium nucleus. the star will have a convective shell and a radiative core just like our own sun see
進行，將四顆氫原子核結合為一顆氦原子核，恆星會有輻射核心和一個對流外殼就像我們的太陽。 -
Reaction, which consists of several steps. interested students should look up the textbooks for a discussion of the details of the p - p chain reaction. the net effect is that four hydrogen nuclei fuse into a helium nucleus and produce a large amount of energy carried away by the photons in the form of gamma ray and others particles
，這種機制包括一連串的核反應有興趣的讀者可參考課本較詳細的討論，但總結果是四顆氫原子熔合為一顆氦原子，過程中會以發放伽瑪射線光子及其他粒子的形式釋放出大量能量。 -
To take place. in this reaction, three helium nuclei will fuse together to form a carbon nucleus
為止，即把三顆氦原子核結合為一顆碳原子核。
