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。

Especially, its operation does not depend on packet dropping. In chapter 5, we have analyzed the relation between link rate and link price of the Newton-like algorithm, which is proposed by Low et al to solve the utility function. And then we reduce the convergence procedure of Newton-like algorithm to a simple recursive procedure along a convex curve after the reduction and mathematical derivation. Thus, we found the reason that leads to the severe fluctuation of the sending rate during its convergence procedure, and then proposed our improved algorithm.

在第五章，我们在对Low等人提出的用于解决效益函数的Newton-like算法的链路速率与链路价格之间关系的深入分析的基础上，经过简化和数学推导，我们将其收敛过程归结为沿着一个凸曲线的非常简单的收敛过程，由此找到了导致Newton-like算法收敛过程中信源速率振荡剧烈的原因，在此基础上，我们提出了一个改进的链路算法。
