本文提出了“形式词”概念,并在形式词的基础上,进一步研究了确定切词单位的非语法因素,包括语义因素、语音因素。在语义因素方面,研究了意义单纯性测定法、意义紧密性测定法、引申意义测定法、常用性测定法;在语音因素方面,研究了停顿判定法、双音节化判定法。最后,提出了视读原则、多元化原则、领域针对性原则等确定切词单位的非语言学的原则。

Based on the conception of formal word , the author inquires into the non-grammatical factors for determination of segmentation element . They include the semantic factors ,phonetic factors. He put forward the corresponding approaches : the semantic simplicity test approach ,the semantic tightness test approach ,the semantic derivation test approach ,the pause test approach ,the disyllabism test approach. Some non-linguistic principles are studied : easy-read principle ,pluralism principle ,domain-oriented principle.
