| 1. | The larger the number of heteroatoms, the more highly oxidized the molecule . 杂原子数越多,分子被氧化的程度越高。 |
| 2. | At low temperatures, the difference in population of atoms between two energy levels, which is the basis of maser action, is greater . 在低温下,作为微波激射作用基础的两个能级之间原子数的差别较大。 |
| 3. | A loss estimation for dropping - back atom number in the atomic fountain 原子喷泉中回落信号原子数损失的估计 |
| 4. | Relativity study on carbon atomic number of normal alkane and property 正构烷烃的碳原子数与物性的相关性研究 |
| 5. | The calculation of crystal cell , atomicity and crystal plane atomicity of nano - kaolinite 原子数和晶面原子数的计算与研究 |
| 6. | The clusters have planar structures with less than 5 atoms and three - dimensional geometric structures with more than 6 atoms 原子数少于5个原子时,铝团簇具有稳定的平面结构,而铝团簇从六个原子的开始具有了三维空间立体结构。 |
| 7. | Most of them are hydrocarbons , compounds of carbon and hydrogen which differ from each other only in the number of carbon and hydrogen atoms in their molecules 它们中的大多数是碳氢化合物,仅仅由于分子中的碳和氢的原子数的差别而彼此不同的碳和氢的化合物。 |
| 8. | " valence number of bonds ( see bonding ) an atom can form . hydrogen ( h ) always has valence 1 , so other elements ' valences equal the number of hydrogen atoms they combine with . 原子价:元素的一个原子能够结合其它原子的数目。元素的特征价数是以该元素一个原子可结合的氢原子数或可从一化合物中置换出的氢原子数来表示。 |
| 9. | It was also found that the number of active atoms has relation with the length of border when the growth rate was low , and the number was largest as the length was shortest 并且发现,在低生长速率情况下,边界长度与可活动原子数间存在对应的周期性振荡关系。当边界长度最小时,可活动原子数为最大;反之,可活动原子数为最小。 |
| 10. | 2 studying of the properties of cbn thin films afm showed that cbn thin film delaminated from substrate obviously . basing xps , we calculate the nib ratio to be 0 . 90 that is closing to unity , and the thickness of hbn layer on cbn layer that is about 0 . 80 nm 根据x射线光电子能谱,计算得到立方氮化硼薄膜中的n和b的原子数比为0 . 90 ,接近理想化学配比1 ;立方氮化硼薄膜顶层的六角氮化硼的厚度约为0 . 80nm 。 |
