It can be concluded from the above analysis that at the beginning of language, simple linguistic signs, coming from sound imitation, natural exclamation and morphological stimulation, took a strong feature of iconicity, while arbitrariness still existed to a little extent. With time going by, the primitives had to create more linguistic signs to meet their needs of survival and development, so that they arbitrarily related the sound patterns and concepts to conventionalize them as linguistic signs adopted in the whole society. During this period of time, arbitrariness played a more important role, while iconicity still worked as phenomena of phonaesthesia designate. With society developing, human beings found that it was not enough to create new signs at will, so they began to make use of some principles like compound, derivation, etc. to form new linguistic signs, either simple or complex. The linguistic signs formed during this period of time always took a better disguise to be iconic, while no one until now could defuse the contributions of arbitrariness of their formation. From the above investigations, it can be seen that arbitrariness and iconicity interact in the whole process of language development at the level of lexicon. If there were no arbitrariness, human language could not expand at the very beginning.
因此可做如下推论:在语言产生之初,简单语言符号的产生常常都是有理据的、象似的,但是仍不排除任意性的作用;后来有理据的词无法满足人们生存和发展的要求,人们开始任意地连接声音形象和概念,并约定俗成获得语言符号,此时任意性起主导作用,但是象似性在音义关系中对语言符号的产生起着不可否认的作用;随着社会的发展,人们发现这些词已经不再能满足需要,而创造更多的词也不是很可能,所以人们开始采用一些构词法来创造新的语言符号,此时产生的语言符号往往更具象似性,但其核心仍然是任意的。

Chapter two proposes the unified form of Hojman"s conservation law and Lutzky"s conservation law. Firstly, the author introduces the general Lie group of transformations that the variations of both the time and the generalized coordinates are considered, derives the determining equation of Lie symmetry for the system, presents a new conservation law, which contains the Hojman"s and the Lutzky"s conservation law as two special cases, and obtains a condition to exclude trivial Hojmans conserved quantities.
第二章,Hojman定理和Lutzky定理的统一形式:首先,引入一般意义下的Lie变换群(即位型变量q_s和时间变量t同时变换),给出系统的Lie对称性确定方程,提出一个新的守恒律,Hojman定理与Lutzky定理则分别是这个新守恒律在两个特殊情况下的推论,导出一个可排除平凡Hojman守恒量的定理,并分别讨论了Birkhoff系统和非完整系统的Lie对称性和Hojman守恒量,最后,讨论了Hamilton系统的梅对称性与Lie对称性的关系,给出了由梅对称性求Hojman守恒量的方法。
