It differs from demasking on one hand and from the masking action defined by IUPAC on the other.───它一方面不同于掩蔽，另一方面又不同于 IUPAC 定义的掩蔽作用。
Multiply unsaturated compounds are usually best named by the IUPAC nomenclature.───多重不饱和化合物一般最好用IUPAC命名法来命名。
Ketones are named by the iupac system as derivatives of the class name for this homologous series "alkanones. ""───系统中，酮是作为这个系列的类名——“烷属酮”的衍生物来命名的。
Ketones are named by the IUPAC system as derivatives of the class name for this homologous series, "alkanones. "───在IUPAC系统中，酮是作为这个系列的类名——“烷属酮”的衍生物来命名的。
Unbranched hydrocarbons having one double bond are named in the IUPAC system by replacing the ending -ane of the alkane name with -ene.───在系统命名法中，直链的、有一个双键的烃可通过将其相应烷烃名字的词尾–ane改换为-ene而得。
It was only in 1997 that the International Union of Pure and Applied Chemistry, or IUPAC, proposed names for 104 - 109.───在1997年国际理论与应用化学联合会（简称IUPAC）就对外征集104——109号元素的名字。
In order to maintain the diversity of population, the algorithm uses the IUPAC degenerate code for mutation.───在算法变异操作中加入IUPAC简并码保持种群的多样性。
In the IUPAC system, alkyl and aryl substituents and many functional groups are named AS prefixes on the parent (for example, iodomethane).───在系统命名法中，烷基、芳基取代基和许多官能团被命名为前缀并放在一个母体的前面（例如：碘甲烷）
