摘要
历史比较法只适用于发生学上有同源关系的语言现象的研究，若超越了这一 范围和条件，它就会走向谬误。不同语言的声调多是独立产生的，相互缺乏同源关 系，因而历史比较法无助于声调起源的研究。语音的易变性和音系结构格局的稳固 性的对立统一规律是支配音变的一种杠杆。结构格局的稳固性决定了古今音变机理 的共同性或相似性，因而可以用从现实语言中总结出来的音变机理去解释历史上已 经完成的音变规律。
The historical comparative method only applies to the study on the related languages,otherwise it will result in falsehood.Most of different languages had their own tonal origins,the historical com- parativistics will be no use for the study.We know the law of the unity of opposites between the vari- ation of the sound and the firmness of the constructional pattern of the sound system.It rules the sound variation.It is the firmness of the constructional pattern of the sound system that has made the general and resemble characters of sound changes all the times,so the sound changes can be ex- plained.
