plutonium fission 中文意思是什麼

plutonium fission 解釋
鈈核裂變, 鈈核分裂
  • plutonium : n. 【化學】鈈。
  • fission : n. 1. 裂開，分裂。2. 【生物學】分裂生殖。3. 【原子能】（核）裂變。vt. ,vi. 【原子能】（使）裂變。
  1. Indirect ionization by neutrons can also result from fission of plutonium or uranium isotopes.

    通過使鈈或鈾同位素裂變，中於也能產生間接的電離作用。
  2. Although almost all this material, which has a 24, 000 - year half - life, has since disappeared ( primarily through natural radioactive decay ), some of the plutonium itself underwent fission, as attested by the presence of its characteristic fission products

    這些物質半衰期為2萬4000年，幾乎已經全部消失（主要是經由自然的放射衰變過程） ，而且部份的鈽本身又經過核分裂，這可由其核分裂產物為證。
  3. It is not, however, the source of a modern bomb ' s main explosive power, for just as the chemical explosives trigger a fission explosion by compressing the plutonium, that fission explosion is used to ignite the third stage, a still - larger fusion explosion, by compressing and heating the main part of the bomb

    然而，該連鎖反應並不是核彈主要爆炸能的源頭，因為它只是化學爆炸物通過壓縮鈈而引發分裂性爆炸，並將進一布引發核彈爆炸的第三個階段，即通過壓縮並加熱核彈主體部位而引起的一種更大范圍的分裂性爆炸。
  4. 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 。
  5. Test method for atom percent fission in uranium and plutonium fuel mass spectrometric method

    用質譜法測定鈾和鈈燃料中原子裂變百分率的試驗方法
  6. Standard test method for atom percent fission in uranium and plutonium fuel neodymium - 148 method

    釹- 148法測定鈾和鈈燃料中原子裂變百分比的標準試驗方法
