一引言音韵学是一门古老的学科,统计法则是一种纯粹的数学方法,将统计法引入音韵学研究中,是一种创新,也是音韵学发展的必然结果。统计方法由于有精确的数字使研究资料量化,又有音韵学的各种方法(如反切比较、韵字系联等)作为辅助,从而可以使音韵研究成为定性研究和定量研究的最佳结合,使研究结果更加准 I. INTRODUCTION Phonology is an ancient subject. Statistical law is a purely mathematical method. The introduction of statistics into the research of phonology is an innovation and the inevitable result of the development of phonology. As a result of the precise number of research data to quantify the statistical methods, there are phonological methods (such as comparison of anti-cut, rhyme system, etc.) as a subsidiary, which can make phonological research qualitative research and quantitative research the best combination, Make research more accurate
