磁性液体中的磁性微粒均匀的分布于液体之中做无规则的布朗运动，当外加1个平行于光透射方向的梯度磁场后，由于磁场和磁性微粒的相互作用，光透射率会发生显著变化，同样加垂直光路的磁场也会影响其光透射率。

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。

Brownian movement and the hydraulic condition required is only that the coagulant can be dispersed in the water rapidly;As the floc is growing further,the condition of making the floc diameters controlled in a certain limit is to be provided as well as the condition favorable for the collision of the floc.

得到细小粒子的凝集动力由布朗运动决定，此阶段只需要有将混凝剂迅速分散于水中的水力条件；在絮体进一步成长过程中除造成有利于絮体碰撞的水力条件外，还要造成絮体粒径控制在某一限度之内的水力条件，这样可以得到密度高、沉淀效果好的絮体。
