All that carbon and oxygen — byproducts of the helium fusion process — build up in its core. At that point the star will shed its outer layers and the core will form a White Dwarf.
所有氦聚变中的附产物碳和氧在它的核心逐渐积聚，这期间它将失掉较外层物质，核心最终枯萎成为白矮星。
It also bodes ill for the prospect of fusion using helium-3, a rare helium isotope that is missing a neutron.
这也预示着，利用氦- 3这种缺少一个中子的稀有的氦同位素进行核聚变的前景很黯淡。
Helium-3 has one less neutron than regular helium (helium-4) and is also produced in the sun and almost as quickly consumed in fusion reactions as deuterium.
氦- 3比普通氦(氦- 4)少一个中子，并且同样在太阳里产生然后象氘一样在核聚变中迅速被消耗掉。
Astronomers talk of placing a radio telescope on the moon's far side; energy experts want to mine the moon's helium 3, an isotope that could power clean-fusion reactors back on Earth.
天文学家想在月球远端放置射电望远镜；能量学家想提取月球上的氦3这种可以驱动清洁融合反应器回到地球的同位素。
Canisters of the harvested helium-3 are then sent to Earth to be used to generate fusion energy.
随后一罐罐的氦- 3就被送至地球用于核聚变产能。
The star used to be like the sun, a "main sequence" star that burns hydrogen by nuclear fusion, producing helium.
这颗恒星曾和太阳一样，是颗“主序星”(“main sequence”)。它通过核聚变燃烧氢，从而产生氦。
Based on the preliminary design of fusion reactor, aiming at the outline of solid blanket design, an advanced helium cooled solid blanket concept was developed.
在聚变堆初步概念设计的基础上，针对固态包层设计路线，提出了一个先进的氦冷固态包层概念。
Astronomers ascribed them to thermonuclear fusion of hydrogen or helium or to the sudden accretion of matter onto the star.
天文学家因此可将其归因于氢或氦的热核融合反应，或是有物质突然被星体吸附而产生的。
The energy of the Sun arises not from any burning process but from nuclear fusion, the transformation of hydrogen into helium, in part by a complicated process involving carbon and nitrogen.
大阳的能量不是来自燃烧过程，而是来自由氢到氦的核聚变，是部分由一个涉及碳和氮的复杂过程引起的。
That simplest fusion reaction, four hydrogens into one helium, works for turning a ball of gas like the Sun, 865,000 miles across, into a shining star.
最简单的核聚变反应，即压迫四个氢原子进入一个氦原子，是相当于把一团象太阳一样的气体从865000公里以外推进一颗闪亮的星星。
Nuclear fusion has created helium, carbon and other chemical elements.
核聚变已产生了氦气，二氧化碳和其他化学元素。
Nuclear fusion has created helium, carbon and other chemical elements.
