helium nucleus meaning in English
氦核
Examples
- Alpha particles are positively charged helium nuclei obtained from natural radioactive decay .
粒子是从天然放射性蜕变得到的带正电的氦核。 - Standard theory predicts that two neutrinos are produced for every fusion of four protons into a helium nucleus .
标准理论预言，在由四个质子变成一个氦核的每一次聚变过程中要产生两个中微子。 - To take place . in this reaction , three helium nuclei will fuse together to form a carbon nucleus
为止，即把三颗氦原子核结合为一颗碳原子核。 - Similar to other main sequence stars , hydrogen nuclei will be fused to helium nuclei in the core
和其他恒星一样，大质量恒星会在主序阶段把氢转化为氦。 - The core meanwhile will reach a temperature of 100 million degrees kelvin , and the helium nuclei will begin fusing into carbon nuclei
在此期间核心温度会达到1亿k ，氦原子核将开始聚变成碳原子核。
