| 1. | In specific acid catalysis, the undissociated acids do not contribute .
在特殊的酸催化中，不离解的酸不起作用。 |
| 2. | When alkali is added to such compounds a series of proton dissociations occurs .
当碱加到这类化合物中，将发生一系列质子离解作用。 |
| 3. | ＠~~the dissociation does not always occur spontaneously, it may be induced by the monomer .
离解反应也不总是自发进行的，它也能被单体所诱导。 |
| 4. | All the atomic and molecular systems are subject to photoionization and photodissociation .
所有的原子和分子系统都受光致电离和光致离解的影响。 |
| 5. | The latter arises from abstraction of the somewhat lesser activated c-h bond in the dioxolane .
后者是由二氧杂环戊烷中活化较弱的C-H键离解而产生的。 |
| 6. | experiments were carried out at 100℃ and pressures sufficiently low to prevent dissolution.
试验是在100和压力低到足以防止离解的条件下进行的。 |
| 7. | This increased optical density caused by a disassociation or melting of the dna is called hyperchromicity .
这种由于DNA离解或融解引起的光密度增加，称之为增色效应。 |
