双语例句
- The crystal structure analysis of photocolored product showed that the photochromic phenomenon was due to photoisomerization from enol form to keto form.
结构分析表明：其光致变色现象是由于它在溶剂与光的共同作用下发生了从醇式到酮式的异构化。 - The keto form predominates in many aldehydes and ketones, the enol form in phenols.
在许多醛和酮中酮基都是最主要的组分。 - The calculation of the thermodynamic parameters shows that the transfor-mation from enol to keto form is endothermic process.
热力学参数的计算表明，从烯醇式到双酮式构型的转变是一个吸热过程。 - Under UV-irradiation, the absorption of enol form decreases, whereas ketone form increases with increasing irradiation time.
当以紫外光进行辐照时，烯醇式异构体不断减少，酮式的含量则不断增多。 - The formation of the 1: 2-bridged hydrogen-bonded complexes makes the keto form lower more energy than the enol form.
1：2桥式氢键的形成使得酮式能量降低比烯醇式多。 - Some isoquinolinium salts are able to react with a wide variety of cyclic enol ethers and cyclic vinyl ethers in Diels-Alder reaction, this is an effective way to form fused ring compounds.

本文就不同条件下烯醇式的互变异构的相对含量作一分析。 - The results showed that two aromatic β-diketone compounds existed in the enol form in chloroform, and they were kinds of good UV-A ultraviolet absorbents in UV region from 320 to 400 nm.
这两种β-二酮化合物在氯仿溶液中主要以烯醇形式存在，并在320~400nm的紫外光区具有强烈的特征吸收，故是一类良好的UV-A紫外线吸收剂。 - The results indicate that β-diketones exist only in the enol form.
结果表明，这些β－二酮仅以烯醇式存在。 - The Content Analysis of The Enol Form Tautomerism
烯醇式互变异构体的含量分析 - It is an obvious feature that the detur groups always take place tautomerism in this process, such as in the excited state enol form transfers to keto form, and result in red-shift of the emission wavelength of molecules.
在此过程中给质子基团往往会发生互变异构现象，如烯醇在激发态时发生烯醇式向酮式转变的互变异构现象，导致分子发射波长向长波长显著移动，这是ESIPT的一个重要特征。
