您要查找的是不是:
- neutron nuclear reaction 中子反应
- slow neutron nuclear reaction 慢中子核反应
- Perhaps nuclear reactions, such as neutron capture? 也许是某种核反应,例如,中子捕获?
- 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。
- neutron induced nuclear reaction 中子核反应
- 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。
- Never have nuclear reactions stopped inside the sun. 在太阳内部;核反应从来没有停止过.
- Using four nuclear reactions as neutron source, the relative efficiency of BF3 long counter in the neutron hall of 4.5 MV Van de Graaf accelerator at Peking University was calibrated. 本工作采用4种不同的核反应作中子源,对北京大学4.;5 MV 静电加速器中子实验大厅的BF3长计数器的相对效率进行了刻度。
- 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。
- miniature neutron nuclear reactor 微型反应堆
- 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。
- 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。
- 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。
