查询词典 H2O

According to the experiment results of degradation in field, degradation mechanism of the biodegradable mulch film can include four stages: the first, the material surface appeared deficiency while the surface area and interstice increased of material in the action of natural environment and microorganism; the second, along with the surface area and interstice of material increased and the gap strengthened, the chemical chain of the high polymer's principal chain broke as a result of the hydrolysis or the enzymatic effect in the action of hydration, causing the molecular weight and mechanics function descended; the third, the molecular of high polymer split the low polymer after its physical mechanical function descended, the material decomposed the fragments, the mass defect intensified; the fourth, the low polymer of fragments form in the natural environment, the microorganism, the biological enzyme became the smaller fragments, thus absorbed by the phagocytes, or further turn into CO2 and H2O due to hydrolysis.

根据田间降解试验结果推测，生物全降解地膜的降解机理可能包括四个阶段：第一，在自然环境、微生物作用下，材料表面出现缺陷，同时表面积增大、空隙增多；第二，随着材料表面积的增大、空隙的增多，吸水性增强，在自水合作用下，高聚物主链由于水解或酶解而使化学链断裂，导致分子量和力学性能下降；第三，在其物理机械性能下降后，高聚物分子链断裂为低聚物分子，材料裂解为碎片状，质量损失加剧；第四，碎片状低聚物在自然环境、微生物、生物酶作用下进一步水解变成尺寸更小的碎片，从而被吞噬细胞吸收，或进一步水解，生成CO2和H2O。

Applying this point to Jackson's argument, we can't move a priori from microphysics to the claim that water covers 60% of the earth because there is a world in which some of what counts as water is ghost water, so even if H2O covers 60% of the earth in that world, what they call 'water' will cover more.

用这一点在Jackson的论证上，我们不能从微观物理学传递先天性给'水覆盖60％'，因为有一个世界有些算作水的东西是水幽灵，所以，即使在那个世界H2O覆盖60％，他们称为"水"的东西会覆盖更多。

What has to be added to microphysics is something that has the upshot that our term 'water' refers to H2O, and it is not clear that this can be done without simply assuming that the microphysical facts determine the referential facts, an assumption that is no part of microphysics.

给微观物理学所必需添加的是某种可以带来'我们的语词『水』所指为『H2O』'这个结果的东西，但在没有简单假设'微观物理学事实决定了所指事实'（——这个假设不是微观物理学的部分）的情况下，不清楚这是否能够做到。

The analysis results of crystal structure shows that the stoichiometric mononuclear Ni complex molecule C(subscript 37.5H45Cl2N10O12Ni was composed of two mononuclear Ni complex units {Ni[C35H33N10O](ClO4)2(CH3OH)2.5(H2O)0.5, Ni coordinated to the ligand to form hexacoordinated distorted octahedral configuration, and the orbital contribution and atomic net charge results has provided a good testimony for the coordinated condition in the crystal structure.

晶体结构分析表明，Ni单核配合物的化学经验式C37.5H45Cl2N10O12Ni的单胞中含有两个配合物分子{Ni[C35H33N10O](ClO4)2(CH3OH)2.5(H2O)0.5}，Ni与配位原子形成六配位的扭曲八面体结构。ab从头算所得原子轨道贡献和原子净电荷布居分析结果与晶体结构中的配位情况相符。

When smooth accelerant is shot by illumination, change smooth energy into electron and cavity above all, next with the oxygen in air (O2) and water element (H2O) reaction, the oxyhydrogen that generates a freeboard oxidation capacity is free base and oxygen anion (O2-).

光触媒被光照射时，把光的能量首先转化成电子和空穴，然后与空气中的氧气(O2)和水分子(H2O)反应，产生具超高氧化能力的氢氧自由基和氧负离子(O2-)。

During the preparation of AlOOH sol , Effects of peptizator, H2O/AL,hydrolysis time, hydrolysis temperature, aging time and composition were studied, it had been found that preparation period could be shortened by extending hydrolysis time. It was possibily because that , iso-propanol produced in the reaction could be volatilized when extending hydrolysis time, its harmful role to peptization process could be avoid in this condition.

在制备AlOOH溶胶过程中，系统研究了胶溶剂、H2O/AL、水解温度、水解时间、陈化温度和陈化时间的影响，并首次发现了延长水解时间可以显著缩短制膜周期，通过分析认为延长水解时间可以使反应过程中生成的异丙醇挥发出去，避免了其对胶溶过程的阻碍作用。

[Cu2(H2O)4]2 was prepared by the reaction of aqueous 1,2,4-triazol-5-one solution with the solution of copper picrate Cu2 and characterized by elemental analysis, FT IR and X-ray powder diffraction analysis.

本文通过1，2，4-三唑-5-酮水溶液与苦味酸铜水溶液反应，制备了[Cu2(H2O)4]2，用元素分析、傅立叶变换红外光谱分析、X-射线粉末衍射分析对其结构进行了表征。

Then, a standard pilot balloon was inflated with cuff pressure by 25 cm H2O, each participant was allowed to palpate the pilot balloon, until confident. After training, the same measurements were performed immediately, one week and one month later.

接著我们将气囊充气到压力值25 cm H2O，然后让每位受试者以手指头触感学习此时适当理想的气管内囊压力，直到他们觉得可以，接著以相同方式在学习完后立刻，一周后、一个月后来测量受试者对的气管内囊充气之压力。

At the location of the south polar vortex for the normal year, the mixing ratios of O3 and CH4 increased, HCl and NO decreased, but NO2 and H2O did not accord with a given rule at all altitudes over Antarctica in 2002, which was related to the change of the vortex and the dynamical transportation after the SSW, and affected by the reduced polar stratospheric clouds and weakened processes of heterogeneous chemistry.

通过比较还发现，在通常年份极涡所处的位置上，2002年O3和CH4的混合比有所增加，HCl和NO的混合比有所减少，而NO2和H2O在不同高度上的变化特点不同。这与爆发性增温之后极涡和动力输送的变化有关，同时由于增温导致极地平流层云中相关冰相反应的减弱也是一个重要的原因。
