| 1. | With neutrons, the light element is not usually at any marked disadvantage . 对于中子,轻元素通常不是一个突出的问题。 |
| 2. | A few elements, among them uranium and thorium, spontaneously disintegrate into lighter elements by chances . 少数元素,其中有铀和钍,通过它们核的变化自然蜕变成较轻的元素。 |
| 3. | Hydrogen is known to be the lightest element 大家都知道,氢是最轻的元素。 |
| 4. | The lightest element is hydrogen 275最轻的元素是氢。 |
| 5. | Disproportionate lighting elements generate both light and an atmosphere that is necessary for the neighbourhood 不成比例的灯产生了适宜的必要的灯和气氛。 |
| 6. | A depth resolution of nano - meter level was achieved to light elements such as c and h with the q3d spectrometer system 用100mev的127i束对c / lif多层样品分析结果表明,表面分辩达到了1 . 2纳米。 |
| 7. | Hydrogen , the lightest element , has a single proton whereas uranium , the heaviest naturally occurring one , has 92 氢是最轻的元素,原子核中只有一个质子,而铀这种自然形成的最重元素的原子核中有92个质子。 |
| 8. | The abundance of those lighter elements allowed scientists to deduce that fission reactions must have gone on for hundreds of thousands of years 这些较轻元素的含量让科学家推论出,核分裂反应必定进行了好几十万年。 |
| 9. | The measurement of light element in the fields of steel industry , metallurgy , geology and environmental protection is an important object 轻元素检测方法的研究是钢铁、冶金、地质和环境等领域中的一个重要研究课题。 |
| 10. | This type of configuration has the advantages of better energy resolution at longer wavelengths ( soft x - ray and light elements ) and a much larger dynamic range than the energy dispersive method 其次利用~ ( 55 ) fe作放射源对探测器和mca多道分析系统进行了标校。 |
