核聚变 (hé jù biàn)

特师的每日一词，2026年2月5日的词汇是：核 hé 聚 jù 变 biàn释义 Definition核聚变是指原子核结合时释放巨大能量的物理过程。核聚变 (hé jù biàn) refers to the physical process where atomic nuclei combine and release a huge amount of energy.例句 Example《凤凰周刊》中，有篇文章是这样用这个词的：「核聚变是通过原子结合释放能量的过程。虽然理论上多种聚变反应都能产生能量，但较常见的是氚同氘聚变生成氦。」这里说的是核聚变的基本原理和常见类型。In Phoenix Weekly, an article uses the term like this: '核聚变 is the process of releasing energy through the combination of atoms. Although theoretically many types of fusion reactions can produce energy, the more common one is the fusion of tritium and deuterium to form helium.' This discusses the basic principle and common type of nuclear fusion.你知道吗？ Did You Know?核聚变与核裂变不同：聚变是轻原子核结合成重核（如太阳发光），裂变是重核分裂成轻核（如核电站）。聚变燃料来自海水中的氘，几乎取之不尽，但需要极高温度才能发生，科学家正努力实现可控核聚变发电。核聚变 (hé jù biàn) is different from 核裂变 (hé liè biàn): fusion is when light atomic nuclei combine to form a heavy nucleus (like the sun shining), while fission is when a heavy nucleus splits into lighter nuclei (like in a nuclear power plant). Fusion fuel comes from deuterium in seawater, which is almost inexhaustible, but it requires extremely high temperatures to occur. Scientists are working hard to achieve controlled 核聚变 (hé jù biàn) for power generation.
