  1. Uranium fission may be accomplished by either fast or slow neutrons.

    鈾的裂變可用快中子或慢中子來完成。
  2. Neutron fluence measurement - part 6 : fast - neutron fluence determination with thorium fission detectors

    中子注量測量.第6部分:用釷裂變探測器測定快中子注量
  3. U - 238 can induce fission after absorbing a high energy neutron fast neutron and then forming the plutonium 239 pu - 239, which is a fissile nuclide

    后極可能產生裂變的核素，鈾- 238則是可裂變的核素。鈾- 238在吸收高能量的中子快中子后，會形成- 239 pu - 239 。
  4. At last, the valid data based fast emd algorithm was proposed. chaper five aimed to the requirement of the emd based time - frequency analysis in the field of rotating machinery signal analysis and fault diagnosis. studied the method of rotatory speed prediction to improve the precision of complete period sampling of vibration signals in rotating machinery, then, discussed the phenomenon of mode fission in noise signal anlysis by emd and provided the filter method to weaken the phenomenon. after then, found a process to analysis the signals using emd - based method in the field of rotating machinery signal analysis and fault diagnosis

    第五章針對旋轉機械信號進行emd時頻分析的要求，提出了提高整周期采樣精度的預測演算法和適合於單片機計算的近似公式；論述了模態裂解現象，並通過模擬信號和實際信號的研究，提出了使用濾波技術來減弱模態裂解現象的方法；給出了適合於旋轉機械振動信號基於emd時頻分析的工作步驟；研究了基於emd的旋轉機械振動信號自適應濾波技術。
  5. Fast - moving neutrons are produced by fission reaction in a nuclear reactor. water is commonly used to moderate and control the speed of neutrons

    核電站的核反應堆中，核裂變會產生高速移動的中子，通常是用水去阻隔及控制中子的移動速度。
  6. Neutron fluence measurement - part 1 : fast - neutron fluence determination with activation and fission detectors

    中子注量測量.第1部分:用活化檢測儀和裂變檢測儀測定
  7. The high energy neutrons released by fission travel at very high speeds fast neutrons and must be slowed down to increase its probability of hitting more uranium atoms and in turn induce more fission in the reactor

    核裂變所釋放的高能量中子移動速度極高快中子，因此必須透過減速，以增加其撞擊鈾原子的機會，同時引發更多核裂變。
  8. The high energy neutrons released by fission travel at very high speeds ( fast neutrons ) and must be slowed down to increase its probability of hitting more uranium atoms and in turn induce more fission in the reactor

    核裂變所釋放的高能量中子移動速度極高（快中子） ，因此必須透過減速，以增加其撞擊鈾原子的機會，同時引發更多核裂變。
