Second, From the internal comparison of linzhang dialect,I find that the difference from east to west is smaller and the difference is larger from south to north ,particularly the southern Zhanghe is affected by vicinity dialects, the tail is abundant and the suffixation of the northen Zhanghe is increasing under the influence of the Standard Chinese. The exterior comparison includes the comparison of the linzhang dialect vocabulary to that of the vicinity and that of the Standard Chinese. The comparison with the vicinity dialects reveals the ralationship of the Linzhang dialects with the vicinity dialects and inquire into its reason. Third, Through the comparison between the dialect and the Standard Chinese from the aspects of sallable, morpheme,affixation, I reveal the vocabulary-made characteristics of the Linzhang dialect---- to have abundant affix. Last, we divide the vocabulary in the Linzhang dialect into the Ancient Chinese words,the Medieval Chinese words,the Modern Chinese words,the Modern Chinese words by the historical view.
