| 4. | The most important chemistry of dithianes, however, lies in their ability to act as a masked carbonyl group .
然而二硫杂环已烷的最重要的性质是它作为一个被掩蔽的羰基。 |
| 5. | Emphasis is on substitution and elimination reactions and chemistry of the carbonyl group
重点强调取代、消除反应和含羰基基团的化学性质。 |
| 6. | Aldehyde a type of organic compound with the general formula rcho , where the - cho group ( the baldheaded group ) consists of a carbonyl group attached to a hydrogen atom
醛:一种组成为rcho的有机化合物， - - cho基团（醛基团）是由碳酰基结合氢原子形成的。 |
| 7. | By repeating these simple kinds of reactions ? adding a carbonyl group here or a hydroxide group there ? we can synthesize a rich variety of complex organic molecules
我们重复这些简单的反应步骤，在这儿塞入一个羰基、那儿接上一个羟基，便可合成种类丰富、构造复杂的有机分子。 |
| 8. | Carbonyl groups readily attach themselves to nickel or cobalt atoms , but not so strongly that they cannot link to other molecules and jump ship to form larger molecules
羰基很容易与镍或钴原子结合，可是键结并不强，因此它还是可以与其他分子结合，甚至跳船形成更大的分子。 |
| 9. | When we conduct experiments using nickel or cobalt sulfides , we see that carbon addition occurs primarily by carbonylation ? the insertion of a carbon and oxygen molecule , or carbonyl group
要是我们以镍或钴的硫化物做实验，增碳过程主要循羰基化途径进行，也就是塞入一个羰基（由一个碳原子、一个氧原子组成） 。 |
| 10. | The studies expressed that the tensile - strength declined with the growth of dose rate after the radiation treatment , and at the same time , the gel content had extreme value with the change of the dose rate . the surface of uhmwpe fibers showed some irregular micro - pits and dents after radiation treatment , narnely rough degree increasing . their number and deepness increased with increase of dose . and this phenomenon is the most obvious when the dose rate was 8 . 5kgy / s and the dose was 400kgy . at the same time some containing oxygen groups , including hydroxyl group , carbonyl group and carboxyl group , were introduced into the fiber surface which was exposed to the air
研究表明， uhmwpe纤维经电子束辐照处理后，纤维的拉伸断裂强度随剂量率的增加呈下降趋势，凝胶含量随着剂量率的变化存在极值。纤维表面出现了不规则的微裂纹和凹痕，随着剂量的增大，电子束对纤维表面的刻蚀程度增加，在本研究中以剂量为400kgy剂量率为8 . 5kgy s时刻蚀效应最为明显。同时，在空气中进行辐照时，纤维表面被引入了一些含氧基团，包括羟基、羰基和羧基。 |
