中文摘要：

现行盲文是唯一把汉语拼音当作文字使用的文字,现行盲文标调问题需要从非同寻常的视角进行研究。以声母为基准,从多方面考察汉语音节的结构和分布规律,并计算出基本音节的平衡性系数和最高频带调音节的隐性标调指数。很多定量研究成果不仅对现行盲文隐性标调有重要价值,对普通的汉语语音研究也具有参考意义。

英文摘要：

Current Braille is the only area in which Hanyu Pinyin is used as a text. The current problem of standard texturing of Braille needs to be studied from an unusual perspective. On the basis of the initial consonants,the structure and distribution of Chinese syllable can be investigated from various aspects,and the balance coefficient of the basic syllable and the recessive tone index of the highest frequency syllable are calculated. Many quantitative research results not only has important value for the existing blind implicit tone,but has reference significance for the study of ordinary Chinese pronunciation.
