查询词典 ring in

At Pt electrode, DHA undergoes hydration reaction to form bicyclic product, and then further transform into 2, 3-diketogulonic acid and its enol form via the opening of lactone ring. At CuCoHCF/Pt electrode, DHA undergoes ring-opening reaction followed by degradation reactions.

但后行反应不同：在裸Pt电极上，DHA进行水化反应生成了双环结构产物，而后开环形成羧酸或烯醇结构；在CuCoHCF/Pt电极上，DHA水化反应生成开环产物，进一步又发生降解反应。

It was found that some main structural factors influencing the RI of organophosphates are 7 substructures such as ＝CH2,≡C—, aaC—(where "a" refers to a chemical bond in the aromatic ring),＝O, O, Cl and Br, which were related to the molecular skeleton of organophosphates, substituent groups on phenyl ring, and alkyls binding to the bond of P—O.

结果表明，影响不同固定相上OP色谱保留的主要结构因素都是由7个ETSI描述子对应的子结构碎片，即：＝CH2，≡C—， aaC—，＝O，—O—， Cl和Br。其中子结构aaC—，＝O和—O与OP化合物母体骨架密切相关，而＝CH2，≡C—，—Cl和—Br反映支链或取代基的变化。
