- Iron is, in fact, the dead end of nuclear reaction. 鐵其實是熱核反應的終站。
- The gadget expedites the reaction of the nuclear reaction. 這一裝置可以加速核反應。
- The energy released by the nuclear reaction is transformed into heat. 核反應中釋放出來的能被轉變為熱。
- The application fields of these kinds of nuclear reaction are indicated. 指出了這幾種核反應的使用領域。
- Perhaps nuclear reactions, such as neutron capture? 也許是某種核反應,例如,中子捕獲?
- 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. 在它初次碰撞時,產生的能量非常巨大,以至於發生了核反應,恆星中的氣體開始持續燃燒。
- The calculations are based on nuclear reaction rates, computed for different stages of a star's life. 計算工作以恆星一生中不同階段具體的核反應速率為基礎。
- Since there is no nuclear reaction inside the protostar, a protostar is not a star yet. 由於在原恆星的核心尚未發生核聚變,它們仍不能稱為真正的恆星。
- Never have nuclear reactions stopped inside the sun. 在太陽內部;核反應從來沒有停止過.
- At the other extreme, a star whose mass is too great will become so hot as a result of accelerated nuclear reaction. 另一極端方面,質量過大的恆星將會由於加快了原子核反應而變得很熱。
- 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. 在它初次碰撞時,產生的能量非常巨大,以至於發生了核反應,恆星中的氣體開始持續燃燒。
- Furthermore, the energy that powers the continuing evolution of the universe apparently can all be traced to nuclear reaction and transformation. 而且,賦予宇宙不斷演化的動力的能量明顯地可追逆到核反應和核蛻變。
- Spontaneous emission of radiation, either directly from unstable atomic nuclei or as a consequence of a nuclear reaction. 自動放射:自動地發出輻射,直接源於不穩定的原子核或是作為核反應的結果。
- Maxim's theory predicts,in early university,the presence of superpartner make it easier and faster for nuclear reaction to occur. 他的理論認為,宇宙初期的超級對子的存在促使宇宙中核反應變得更容易和更快。
- They give concrete evidence that nuclear reactions are proceeding in stars. 它們給出了恆星內正在不斷進行的核反應的確實證據。
- Transformation of one element into another by one or a series of nuclear reactions. 嬗變通過一次或一系列核反應把一種元素轉化為另一種元素
- Deuterium behaviour in TiD x /Mo was investigated by ion beam analysis of nuclear reaction analysis(NRA),elastic recoil detection (ERD),rutherford backscattering(RBS). 用核反應分析(NRA)、前向反衝分析法(ERD)、背散射譜法(RBS)等離子束分析方法研究了TiDx/Mo樣品中氘的行為。
- This observational result provides a strong constraint on the theoretical models of nuclear reaction processes that produce heavy elements in the universe. 這一觀測結果提供了強有力的制約;理論模型的核反應過程產生的重元素宇宙.
- Finally, there should be no significant amounts of boron, lithium or other so-called poisons, which absorb neutrons and would thus bring any nuclear reaction to a swift halt. 最後一點,周圍不能有大量的硼、鋰或其他稱為抑製劑的物質;這些物質會吸收中子,使核反應中止。
