术语“热核爆炸”的详细信息

英译术语:

thermonuclear explosion

汉语语境:

一种元素通常为氢或氦加热到原子核变得不稳定的程度下发生热核爆炸。结果是融合，原子结合形成更重元素的原子，并释放出大量的能量以维持产生融合的热量。在一枚氢弹中，达到所需温度的初始能量是由一枚小原子（裂变）弹提供的。热核能在一次大爆炸中消散。这个过程通常发生在太阳或恒星中。

英语语境:

A thermonuclear explosion occurs when an element, usually hydrogen or helium, is heated to the point that the nuclei of atoms become unstable. The result is fusion, when atoms combine to form the atoms of heavier elements, giving off enormous amounts of energy, which sustains the heat that resulted in fusion. In a “hydrogen“ bomb, the initial energy to achieve the required temperature is provided by a small atomic (fission) bomb. The thermonuclear energy is dissipated in an enormous explosion. This process occurs naturally in the sun and stars.
