beta decay 解釋
【原子能】β衰變。

  • beta : n. 1. 希臘字母第二字 [B,β]。2. 第二位的東西。3. 【天文學】β星〈星座中第二等最亮的星〉。
  • decay : vi. 1. 朽，腐爛。2. 衰減，衰退。3. 凋謝，枯。vt. 使朽壞；使衰退。n. 1. 衰微，衰退。2. 朽，腐爛。3. 【無線電】衰變。
  1. Let us very briefly rehearse one or two facts about nuclear beta decay.

    讓我們非常簡要地復述一下有關該衰變的一兩件事實。
  2. The radioactive transformation giving rise to these electrons was known as beta decay.

    產生這種電子的放射性變化，稱為衰變。
  3. The shape of the electron spectrum in beta decay is not dominated by properties of the matrix element.

    衰變的電子譜的形狀不取決于矩陣元的性質。
  4. Couched in mathematical language within the framework of the quantum theory, it gave a satisfying explanation of beta decay.

    如按量子理論的觀點表達為數學語言，就可對衰變作出滿意的解釋。
  5. These radionuclides undergo radioactive decay, by emitting harmful alpha particles, beta particles or gamma rays

    它們在衰變期間會放出對人體有害的粒子粒子或射線。
  6. In some kinds of beta decay, a nuclide loses surplus positive charge by emitting a positron ( in the same event, a proton becomes a neutron, and neutrinos are also given off )

    以某種貝它衰減，一個核素靠發出一個正電子失去剩餘正電荷（在相同的事件中，一個質子變成一個中子，而且也發射微中子） 。
  7. They designed sophisticated experiments to test their hypothesis and proposed them to another chinese physicist, c. s. wu, who later confirmed their prediction of symmetry breakown in the beta decay experiment of cobalt

    美籍華裔物理學家楊振寧和李政道教授相信自然界並非如此，他們提出論據並由另一位華裔物理學家吳健雄博士通過鈷的衰變實驗所證實。
