国家有关部门就汉语拼音的拼写规则先后颁布了一系列的规定，其中包括作为国家标准的《汉语拼音正词法基本规则》。但修订后的《现代汉语词典》在注音拼写方面仍存在着不少与这些规定相抵牾或内部自相矛盾之处。本文用大量具体例证指出了《现代汉语词典》在注音拼写的大小写方面所存在的问题，并希望这些问题能在再修订时加以解决。 Relevant departments of the state promulgated a series of provisions on the spelling rules of Hanyu Pinyin, including the “Hanyu Pinyin Orthographic Law Basic Rules” as a national standard. However, there are still many inconsistencies or internal contradictions in the revised Modern Chinese Dictionary in phonetic transcription. In this paper, a large number of concrete examples are used to point out the problems existing in the modern Chinese dictionaries in the case of phonetic spelling and hope that these problems can be solved when revisions are made.
