您要查找的是不是:
- 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
- Perhaps nuclear reactions, such as neutron capture? 也许是某种核反应,例如,中子捕获?
- Iron is, in fact, the dead end of nuclear reaction. 铁其实是热核反应的终站。
- Never have nuclear reactions stopped inside the sun. 在太阳内部;核反应从来没有停止过.
- 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。
- The gadget expedites the reaction of the nuclear reaction. 这一装置可以加速核反应。
- 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
- 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。
- Nuclear reactions may be induced by bombardment with a wide variety of particles. 核反应可以通过各种各样粒子轰击来诱发。
- There are two types of nuclear reactions in which large amounts of energy may be liberated. 有两种类型的核反应,可以从中释放大量的能量。
- It is worth emphasizing that the nuclear reactions occurring in the interior of the sun and stars are thermonuclear. 值得强调指出,发生在太阳和恒星内部的核反应是热核反应。
- These massive stars explode when the fuel that sustains nuclear reactions inside their cores is depleted. 当其内核中支撑核反应的燃料耗尽时,这些大质量恒星将会爆炸。
- These signals are produced by colliding stars or nuclear reactions in outer space. 这些信号是由外层星球的相撞或核反应所产生的。
- To make stars you need colossal clouds of frigid gas that will collapse to begin star-producing nuclear reactions. 恒星的形成需要大团的寒冷气体发生塌缩,以便开动创造恒星所需的核反应。
- Nuclear reactions are taking place con tenuously inside the sun , giving the sun its constant supply of energy. 核反应在太阳内部连续发生,从而源源不断地给太阳提供能量。
- Nuclear reactions in such a star's core, the source of power for nearly its entire life, deplete the available hydrogen, then the helium. 恒星一生的能量来源,几乎都来自中心的核反应,过程中会耗尽所有可用的氢,然后是氦。
- Paradoxical as it may seem, the value of a star's luminosity does not depend on the nuclear reactions taking place in the interior. 看来十分奇怪的是,恒星的光度竟然与发生在内部的核反应无关。
- Thus, our Sun is a star but Jupiter is not. When a star ceases to have nuclear reactions anymore, we say the star is dead. 当一颗恒星核心内的热核反应停止,它便不再是一颗真正的恒星,我们会说这恒星已死。
- The nuclear reactions in the interior of the sun, including PPI reactionand CNO cycle, are discussed by the method of nonequilibrium thermodyna-mics. 本文应用非平衡热力学方法讨论了太阳内部热核反应,包括PPI反应及CNO循环的稳定性问题。
