查询词典 reaction coil

A large number of bond-type complexes, as long as the hydrogen of the molecules covalently coupled to the molecular approach in an electronegative atom up, that constitutes a hydrogen bond, there are intramolecular hydrogen bonds and intermolecular hydrogen bonds of the points, will affect the formation of complex reaction carried out, such as in solution adding dioxa cyclohexane, or tetrahydrofuran, will reduce the alkylation reaction rate.

氢键型络合物为数众多，只要含氢的分子以共价键方式耦合到分子中一个电负性原子上去，即构成氢键，有分子内氢键和分子间氢键之分，络合物的形成将会影响反应的进行，如在溶液中加入二氧杂环己烷或四氢呋喃，都会降低烷基化反应速率。

Reactive dye not only can covalently bind with modified flax by nucleophilic reaction, but also can form electrovalent bond. Attracting among hydronium is of benefit to nucleophilic reaction.

改性亚麻与活性染料之间即可发生亲核取代反应形成共价键结合，又可形成离子间的库仑力，而且离子间的相互吸引更有利于染料上的活性基与纤维素发生亲核取代反应。

The chain-condensation reaction and its reversible reaction are the key controlling elementary reactions of the copolymerization mechanism for the studied system,while the chain initiation elementary reactions are not the key controlling elementary reactions of the copolymerization mechanism for the studied system.

其中，链引发及其逆反应对D4/APAEDMS的本体共聚反应没有直接调控作用，而链缩合及其逆反应是本体系反应机理不同于纯活性阴离子聚合或逐步聚合反应机理的关键原因。

"If it is positive, the reaction is endothermic; if it is negative, the reaction is exothermic."

如果这个热量是正的，就说这个反应是吸热的；如果反应热是负的，那就是放热反应。
