中文摘要：

在在世界上的现代语言之中的基本差别被词音节结构(WSS ) ，不是由特殊音素有。语言差异应当是 WSS 的进化结果，它被音节被音节宪法和词的长度的类型决定。这里，我们使用 179 种现代语言的 Swadesh 表分析他们 WSS 差异索引和尝试的地理分发在进化过程发现他们的发展中的位置和深度。我们也使理想的 WSS 偏移量为语言当模特儿，计算偏移量距离和每种语言的偏移量方向，然后把语言划分成根据数据结果，其各个代表一种进化类型的三个组。我们的结论是 WSS 差异和 WSS 偏移量模型在世界上代表差异的进化趋势和人的语言的进化过程。另外，每种语言现在保留最主要的 WSS 特征到某程度。因此， WSS 可以被认为是人的语言的基因因素。

英文摘要：

A fundamental difference among modem lan- guages in the world are made by word-syllable structures （WSS）, not by distinctive phonemes. Language diversity is supposed to be an evolutionary result of the WSSs, which is decided by types of syllable constitution and the length of word by syllables. Here we use Swadesh lists of 179 modem languages to analyze their geographic distribution of WSS diversity index and try to discover their developing positions and depths in the evolutionary processes. We also set an ideal WSS offset model for languages, calculate the offset distance and offset direction of each language, and then divide languages into three groups according to the data result, each of which represents an evolutionary type. Our conclusion is that the WSS diversity and the WSS offset model represent the evolutionary trend of diversity and the evolutionary process of human languages in the world. In addition, every language nowadays keeps the most primary WSS features to some extent. Therefore, the WSS may be regarded as genetic factors of human languages.
