| 1. | The strong interaction between two nuclear particles gives rise to a very strong force only when they are close together . 两个核粒子间的强相互作用仅在粒子十分接近时才能形成很强的作用力。 |
| 2. | The stability of a nucleus can be described in terms of a number of parameters 原子核的稳定度可以用若干参数来描述,其中一个参数是核粒子的结合能。 |
| 3. | The stability of a nucleus can be described in terms of a number of parameters 原子核的稳定度可以用若干参数来描述,其中一个参数是核粒子的结合能。 |
| 4. | One such parameter is the binding energy of particles inside the nucleus , i . e . the nucleons 原子核的总结合能是指把原子核分开成为独立核粒子所需的能量。 |
| 5. | One such parameter is the binding energy of particles inside the nucleus , i . e . the nucleons 原子核的总结合能是指把原子核分开成为独立核粒子所需的能量。 |
| 6. | The total binding energy of a nucleus is defined as the energy that would be required to separate the nucleus into separate nucleons 换句话说,独立核粒子结合组成一个原子核,就会释放出相等于该原子核的总结合能的能量。 |
| 7. | The total binding energy of a nucleus is defined as the energy that would be required to separate the nucleus into separate nucleons 换句话说,独立核粒子结合组成一个原子核,就会释放出相等于该原子核的总结合能的能量。 |
| 8. | In other words , the same amount of energy will be given off when stand - alone nucleons come together to form the nucleus . when the binding energy per nucleon is plotted against the mass number , i . e . total number of protons and neutrons in a nucleus the bottom right figure , it is found that the curve peaks around the mass number 56 , i . e . the iron nucleus 如果把原子核内每颗核粒子的平均结合能又称比结合能与质量数原子核中的质子和中子的总数绘制成图右下图,便可发现图中曲线在质量数大约等于56即铁原子核时到达最高点,即是铁原子核的总体能量最低。 |
| 9. | Nuclear particle track - etched anti - counterfeit marking is a new weapon against fake products . the mark is manufactured by intricate high technology in state - controlled sensitive nuclear facilities which ensures that the mark can not be copied . the pattern of the mark is characterized by its permeability , and can be distinguished from fakes by using a transparent liquid ( e . g . water ) , colored pen or chemical reagent . the technique has passed the official health safety examination and poses no danger of nuclear irradiation 用核粒子照射塑料薄膜形成径迹,再经化学试剂蚀刻和成像技术,得到由微米级微孔组成的图案.这种图案具有物质透过特性.用这种方法生产的核径迹防伪标志,具备核尖端技术不易扩散,制作设备不易得到,产品用其他方法难以伪造,防伪识别简单、快速、可靠等特点.此种标志已经通过放射性安全检测,可以用于各种商品(包括食品)的包装 |
| 10. | In other words , the same amount of energy will be given off when stand - alone nucleons come together to form the nucleus . when the binding energy per nucleon is plotted against the mass number , i . e . total number of protons and neutrons in a nucleus ( the bottom right figure ) , it is found that the curve peaks around the mass number 56 , i . e . the iron nucleus 如果把原子核内每颗核粒子的平均结合能(又称比结合能)与质量数(原子核中的质子和中子的总数)绘制成图(右下图) ,便可发现图中曲线在质量数大约等于56 (即铁原子核)时到达最高点,即是铁原子核的总体能量最低。 |
