oxygen-18 ice core record 氧18冰蕊纪录
Researchers' clues to the Eemian climate come from measurements of the ratios of two slightly different types of oxygen, isotopes oxygen-16 and oxygen-18, preserved in the GRIP core.
研究人员对间冰期气候的线索来自保存在 GRIP 冰芯中的两种略微不同类型的氧——即同位素氧-16和氧-18的比率。
In larger stars, pressure at the core is high enough to fuse heavier elements such as oxygen and carbon, creating more photons.
对于更大的恒星,核心的压力大得足以使更重元素进行聚变反应,比如氧和碳元素,它们将创造更多的光子。
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。
