查询词典 H2O

The results show that a MgSnO3·H2O conversion film is formed by treatment in the stannate solution at 90℃, and the immersion test and potentiodynamic polarization show that the corrosion resistance of the AZ91D alloy is improved to some extent.

结果表明：锡酸盐转化处理后合金表面形成了以MgSnO3·H2O为主要成分的转化膜，可对合金起到一定的防护作用；转化膜由细小的球形颗粒密积而成，颗粒之间存在间隙，它可以为化学镀镍的前处理过程提供良好的吸附条件；转化膜上的化学镀镍层组织致密、无缺陷， MgSnO3·H2O转化膜在镀镍层与基体之间起到过渡作用，镀层的磷含量达到9%，与基体结合良好；在3.5% NaCl (pH=7)溶液中的动电位极化测试表明，镀镍以后的合金在阳极极化过程中发生了明显的钝化，耐腐蚀性能进一步提高，对基体起到了较好的防护作用。

After analysis and study of characters of observational parameters of these extragalactic H2O megamaser sources, the correlations among them have been obtained as follows: lg S peak is anticorrelated with lg V sys and lg D , respectively.

通过对这些河外H2O超脉泽源的观测参数的特征的分析和研究，得到这些观测参数之间的相关关系为：河外H2O超脉泽源的峰值流量密度的对数分别与系统速度的对数和距离的对数之间存在着反相关关系。

Since the first extragalactic H2O megamaser source toward the Active Galactic Nuclei NGC 4945 was discovered, 19 sources have been found.

自从在活动星系核NGC 4945的视线方向上发现第一个河外H2O超脉泽源以来，迄今为止已发现了19个河外H2O超脉泽源。

Two organosulfonate complexes, [M22]·H2O (M=Cd 1, M=Pb 2), were obtained from the reaction of 1,10-phenanthroline, sodium 4-aminonaphthalene-1-sulfonate tetrahydrate and Cd2·2H2O or Pb (NO3)2 in a mixed solvent of water and methanol at 25 ℃. The compounds were characterized by elemental analysis, IR, and X-ray diffraction single crystal structure analyses.

合成了2个新型有机磺酸配合物，[Cd22]·H2O(1)和[Pb22]·H2O(2)(phen=1，10-邻菲咯啉，ans=4-氨基-1-萘磺酸根)，通过元素分析、红外光谱等对配合物进了表征，用X-射线单晶衍射方法测定了配合物的单晶结构。

Influence of the chemicals on the composition of pyrolysis products of Tilia amurensis lignin was discussed. During the pyrolysis process, a great deal of CO2, CO and H2O was produced, which was mainly attributed to the elimination of carbonyl, carboxyl, hydroxyl, methyl and the further reaction to form polycyclic aromatic hydrocarbons.

结果表明：木质素在裂解过程中，产生大量的CO2、CO、H2O，其主要原因是高温时羰基、羧基、羟基、甲基等脱除反应以及环芳香族化反应深入进行，而所选用的阻燃剂大多数促进了CO2、CO、H2O的产生。

Even if it is a microphysical fact that H2O is a waterish stuff around here, it is not a microphysical fact that it is the waterish stuff around here.

即使这是微观物理学事实&H2O是这里的某种水性材料&，但&这/H2O就是这里的这些水性材料&也不是一个微观物理学事实。

Then the overall argument says that the two microphysical facts, that H2O covers 60% of the globe and that H2O = the waterish stuff around here, together with the conceptual truth, logically imply that water covers 60% of the globe.

那么，整个论证说的是两个微观物理事实：H2O覆盖地球的60％表面，H2O＝这里的这些水性材料，加上概念真，逻辑上就蕴涵水覆盖地球的60％表面。

The ore-forming fluid of this kind of deposits is mixture of basinal hot brines with CaCl2-NaCl-H2O system and seawater with NaCl-H2O system.

该类矿成矿流体为CaCl2-NaCl-H2O体系盆地热卤水和NaCl-H2O体系正常海水的混合水。

Two coordination polymers [Pb6(H2O)24]·3H2O(1)(H3cit=citric acid)and Pb(H2O)2(2)(tar=tartaric acid)were synthesized under hydrothermal conditions and characterized via IR,TG-DTA,C,H,N elemental analysis,XRD and single crystal X-ray diffraction analysis.

在水热条件下，合成了2个含柔性配体柠檬酸和酒石酸的二价铅配位聚合物[Pb6(H2O)24]。3H2O(1)(H3cit=citricacid)及Pb(H2O)2(2)(tar=tartaricacid)。用红外光谱、差热-热重、元素分析、粉末X射线衍射及单晶X射线衍射等手段对化合物进行了表征。化合物1属三斜晶系，P1空间群，a=0.97053(19)nm，b=0.9764(2)nm，c=1.0955(2)nm，α=109.016(3)°，β=98.380(3)°，γ=92.136(3)°，V=0.9671(3)nm3，Z=2，R1=0.0420，wR2=0.1049，GOF=1.064。

The canonical intuition is that XYZ isn't water because being made of H2O is an essential property of water; whatever is a sample of water is ipso facto a sample of H2O, and nothing else could be.

标准的直觉是：XYZ不是水，因为由H2O构成是水的本质特性，水的任何一个样品事实上都是一件H2O的样品，由其他任何成分构成的都不可能是水。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
