查询词典 H2O

The invention relates to a method for stocking and preserving green round wood and sawn timber, which is stored in an airtight and lighttight sealing cover. The oxygen inside the cover is decomposed by the respiratory process of mushrooms, bacteria and wood cells that are still alive, thereby forming CO2 and H2O.

本发明涉及用来保存绿圆木或锯成木材的方法，其中将绿圆木或锯成木材储存在不透气和不透光的包覆层下面，所述包覆层以内的氧气被真菌和细菌的呼吸和发酵过程以及仍然存活的木细胞的呼吸过程所消化，因此产生CO2、H2O。

The results showed that monocarboxylic acid stearic acid played a role of surfactant, and the product was still orthorhombic Ce2O(CO3)2·H2O with a high crystallization degree. In turn, duality-carboxylic acid tartaric acid...

实验结果表明在尿素及硝酸铈的混合溶液中分别加入一元羧酸硬脂酸，二元羧酸酒石酸和三元羧酸柠檬酸时，一元羧酸硬脂酸在混合溶液中只起表面活性剂的作用，其产物为斜方晶系的单晶Ce2O(CO3)2.H2O微粉，且表面活性剂硬脂酸的加入使得晶体的晶化程度明显提高；而二元羧酸酒石酸与三元羧酸柠檬酸在均相反应中则起螯合剂的作用，分别与Ce3+形成螯合物酒石酸铈和柠檬酸铈，这些结果的造成是由于其反应机理的不同所导致的。

Further application of the partially perturbative density functional theory to MX2-NX-H2O solution indicates that the present theory is better than the Poisson-Boltzmann equation and can be used to predict the structures and ion-partitioning of high-valent ions in charged nanopores.

对混合电解质溶液MX2-NX-H2O的结果同样表明本文的部分微扰的密度泛函理论要好于传统的Poisson-Boltzmann方程，且能够预测高价离子在带电纳米孔内的结构与分配。

The mineralization of a number of deposits of this class were associated with certain types of host rocks, but the most were formed by the unmixing of H2O-CO2-salt fluid with very high salinities and the mineralization is commonly linked to potassic alteration.

部分该类矿床的形成与一定的主岩类型有关，而多数矿床可能由高盐度H2O-CO2-盐混合流体的不混溶作用形成，且矿化通常与钾化有关。
