不饱和性 meaning in English
nonsaturation
u aturation
unsaturation
Examples
- Standard test method for polyurethane raw materials determination of unsaturation of polyols
聚氨酯原材料的标准试验方法:多元醇不饱和性的测定 - Standard test method for vinylidene unsaturation in polyethylene by infrared spectrophotometry
用红外线光度分光光度法测定聚乙烯中乙烯不饱和性的试验方法 - Standard test method for vinyl and trans unsaturation in polyethylene by infrared spectrophotometry
用红外线分光光度法对乙烯基和横相不饱和性的标准试验方法 - Then , analytical work was carried out as follows : the ultimate analysis and physi - chemical analysis of the pyrolytic oil comprised a sketch of the fuel properties of the oil ; then , through the distillation analysis of the oil , the fraction composition of the " unrefined " oil was known . after that , a general knowledge of the aromaticity and saturation of the hydrocarbons in the oil was provided by the outcome of the ft - ir functional group analysis . also , from the analysis , the form of the polar functional groups and their distribution in different fractions of the oil were learned
文中首先对不同热解温度下热解油产率进行分析讨论，然后，针对热解油品质进行了一系列分析：通过元素组成和理化特性的分析，对热解油作为燃料特性有了一个大致了解；通过实沸点蒸馏分析，得到热解油作为一种未提炼油的馏分分布，并为后续热解油馏分的细入分析提供了前提；通过对热解全油和各窄馏分的ft - ir官能团分析，对热解油的芳香性、不饱和性有了整体的了解，并且清楚了热解油中的极性官能团存在型式及其在热解油不同馏分中的分布。 - Gas chromatography - mass spectrometry ( gc - ms ) analyses showed that both potassium permanganate and chlorine could oxidate the organic matters with unsaturated functional groups into those with carboxyl , hydroxyl and aldehyde . and it was further revealed that after preoxidation by potassium permanganate , the sorts of organic matters were reduced remarkably , however , chlorination leaded to increase of the sorts of orgnic matters and brought some chloro - organics such as chlorobenzene , chlorophenol , and trichloro - ethane
通过色谱-质谱联用( gc - ms )评价分析了高锰酸钾和氯对有机物结构的改变，高锰酸钾和氯均将原水中的一些不饱和性有机物氧化分解为一些含氧基团的有机物，如羧酸类、醇类和醛等有机物，但预氯化会在水中出现一些卤代物，卤代产物不仅出现在苯环上，而且出现在链烃上。
