词汇 | oxidize |
释义 | oxidize verb[ I or T ] (UK usuallyoxidise)uk /ˈɒk.sɪ.daɪz/ us /ˈɑːk.sə.daɪz/ If a substance oxidizes, it combines with oxygen and loses hydrogen to form another substance, and if something oxidizes a substance, it causes it to do this: 氧化;生锈 Iron oxidizes to form rust.铁氧化形成铁锈。 When you heat fat, it oxidizes easily.脂肪在燃烧时迅速氧化。 If a chemical element oxidizes, it loses electrons (= very small pieces of matter with negative electrical charge) and if you oxidize it, you cause it to do this.(使)氧化 Physical & chemical processes absorbable absorptive absorptive capacity absorptivity acidification aerate endothermic reaction excitability excitation excite exergonic exothermic impregnate re-emit reabsorb react reboil recondense scald vaporize Related wordoxidization oxidize | American Dictionaryoxidize verb[ I/T ] us/ˈɑk·sɪˌdɑɪz/ chemistry to react with oxygen and rust chemistry Oxidize also means to cause an atom or group of atoms to lose electrons during a chemical reaction. Examples of oxidizeoxidize Various elements, such as iron, titanium, manganese and sulphur can be oxidized to form oxides or hydroxides. Moreover, the assumption that the ferrous iron is only oxidized by oxygen is likely to fail when nitrate is present in appreciable amounts. Scarification by heat, acid treatments, bleach, oxidizing gases and mechanical abrasion are some of the traditional procedures known to elicit germination. Acids and oxidizing agents may weaken layers of tissues surrounding the embryo and allow emergence of the embryo. Consequently, the species losing electrons are virtually oxidized. The electric current is generated by electrochemically oxidizing the ferrocyanide ion. Conversely, under oxidizing conditions they do not form at all or do so only in small amounts in hydrothermal vents or in localized hydrogen-rich regions. The presence of oxidizing groups was denoted as areas of discolouration. As illustrated by the examples above, an array of chemical modifications obtained by oxidizing cysteinyl residues has been exploited in combating oxidative stress. The sediments are moderate to well sorted, and are highly oxidized with little or no preservation of physical structures. The implications for this work are immediately clear: for modern hydrothermal systems hosted in relatively oxidizing basaltic environments, organic synthesis is not favoured. In astrocytes, glutamine is oxidized to a-ketoglutarate which can also be transported to neurons and participate in glutamate synthesis. Our studies focus on why lactate generated in brain astrocytes is not oxidized locally. The redox potential suggests oxidizing conditions throughout the section. A renewed episode of significant lake deepening took place during deposition of unit 4, which at this time occur red under dominantly oxidizing conditions.
