This paper starts with the Naroll-Bertalanffy's hypothesis of the allometric growth of urban-rural population, namely and Sherratt's model about the distribution of urban population density, which are both based on the Christaller-l o ··sch's central place hypothesis and the hypothesis of supposing the regional population movement on the ideal land surface is similar to Brownian movement process.

基于中心地假设，从城市人口分布的Sherratt模型和Naroll Bertalanffy的城乡人口异速生长关系出发导出关于人口分布空间动力学和城市扩展时空过程的数学模型，然后借助Batty等关于城市生长的DLA -DBM模拟结果证明人口的区位选择过程与城市的分形形态存在着内在关系。

According to the some properties of the differentiation ,I found that the symmetry of the graph is closely related to the first-order differentiation and the second-order differentiation .from this ,I search for a way to identify the symmetry of the functional graph for the direct line or the central symmetry of the functional graph for the some dot .

摘 要：利用导数的一些性质，发现了函数图象的对称性与函数的一阶、二阶导数的密切关系。根据这些关系，找到了一种判定函数图象是否关于某一直线对称或关于某点成中心对称的方法。
