字母词在新时期大量涌现 ,它作为汉语词的性质也逐渐得到学界的承认 ,但人们对字母词的读音问题却尚未形成统一的认识。许多词典在收录字母词的同时 ,都对字母的注音采取了回避的态度 ,理由多是认为字母的读音是按西文音读的。本文认为 ,语音形式未经汉化的字母词是无法进入汉语词汇系统的 ,而汉语语音系统的开放性和语音之间的相似性决定了用汉语拼音给字母注音的可行性 ,本文就是针对这一问题展开论述的。 Alphabetic words emerged in a great amount in the new period. As the nature of Chinese words, they have also been gradually recognized by the academic circles. However, people have not yet formed a unified understanding of the pronunciation of alphabetic words. Many dictionaries include the letter words at the same time, have taken the attitude of the phonetic alphabet to avoid, for many reasons that the alphabetic pronunciation is pronounced in Western languages. This paper argues that unmodified phonetic forms of phonetic forms can not enter the Chinese lexical system. However, the openness of Chinese phonetic system and the similarities between phonetic sounds determine the feasibility of phonetic transcription with Hanyu pinyin, The problem is discussed.
