- direct nuclear reaction 直接核反应
- The point at which a nuclear reaction is self-sustaining. 临界点核反应能够自我维持的一个点
- Iron is, in fact, the dead end of nuclear reaction. 铁其实是热核反应的终站。
- The gadget expedites the reaction of the nuclear reaction. 这一装置可以加速核反应。
- The energy released by the nuclear reaction is transformed into heat. 核反应中释放出来的能被转变为热。
- The application fields of these kinds of nuclear reaction are indicated. 指出了这几种核反应的使用领域。
- Perhaps nuclear reactions, such as neutron capture? 也许是某种核反应，例如，中子捕获?
- This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to bum continuously. 在它初次碰撞时，产生的能量非常巨大，以至于发生了核反应，恒星中的气体开始持续燃烧。
- The calculations are based on nuclear reaction rates, computed for different stages of a star's life. 计算工作以恒星一生中不同阶段具体的核反应速率为基础。
- Never have nuclear reactions stopped inside the sun. 在太阳内部;核反应从来没有停止过.
- Since there is no nuclear reaction inside the protostar, a protostar is not a star yet. 由于在原恒星的核心尚未发生核聚变,它们仍不能称为真正的恒星。
- At the other extreme, a star whose mass is too great will become so hot as a result of accelerated nuclear reaction. 另一极端方面,质量过大的恒星将会由于加快了原子核反应而变得很热。
- This energy produced is so great when it first collides,that a nuclear reaction occurs and the gases within the star start to bum continuously. 在它初次碰撞时，产生的能量非常巨大，以至于发生了核反应，恒星中的气体开始持续燃烧。
- Furthermore, the energy that powers the continuing evolution of the universe apparently can all be traced to nuclear reaction and transformation. 而且，赋予宇宙不断演化的动力的能量明显地可追逆到核反应和核蜕变。
- helium-mercury direct nuclear laser 氦汞直接核抽运激光器
- Spontaneous emission of radiation, either directly from unstable atomic nuclei or as a consequence of a nuclear reaction. 自动放射:自动地发出辐射,直接源于不稳定的原子核或是作为核反应的结果。
- They give concrete evidence that nuclear reactions are proceeding in stars. 它们给出了恒星内正在不断进行的核反应的确实证据。
- Maxim's theory predicts,in early university,the presence of superpartner make it easier and faster for nuclear reaction to occur. 他的理论认为，宇宙初期的超级对子的存在促使宇宙中核反应变得更容易和更快。
- Transformation of one element into another by one or a series of nuclear reactions. 嬗变通过一次或一系列核反应把一种元素转化为另一种元素
- Deuterium behaviour in TiD x /Mo was investigated by ion beam analysis of nuclear reaction analysis(NRA),elastic recoil detection (ERD),rutherford backscattering(RBS). 用核反应分析（NRA）、前向反冲分析法（ERD）、背散射谱法（RBS）等离子束分析方法研究了TiDx/Mo样品中氘的行为。
