| 1. | Let us very briefly rehearse one or two facts about nuclear beta decay . 让我们非常简要地复述一下有关该衰变的一两件事实。 |
| 2. | The actual rate of decay may be somewhat greater or less than this expected rate . 衰变的实际速率可以比这个预期速率稍大些或稍小些。 |
| 3. | The shape of the electron spectrum in beta decay is not dominated by properties of the matrix element . 衰变的电子谱的形状不取决于矩阵元的性质。 |
| 4. | Because of the continuous decay, the quantity of radioactive material and the rate of emission of radiation decrease steadily . 由于连续衰变的结果,放射性物质的数量,辐射发射率都逐渐下降。 |
