求翻译：将各层域依据所处层的层数，分别进行平均划分（即第i层平均划分为i部分，且均以sink为圆心进行划分，如图1（2）所示），从而形成一个个网格，每个网格内部署的传感节点将形成静态簇，如图1（3）所示，我们用Aijk（1≤k≤i）表示各静态簇，其中第一层各层域独立形成簇，即A111=A11,A121=A12,A131=A13。由平面几何知识易知，这种划分将确保所有网格较长的弧长均相同，进而使得同一层中各个簇的面积均相同，且处于不同层的各个簇的面积相差亦有限。记各簇中节点数为Nijk，各层域中节点数为Nij，则有Nij=Nij1+Nij2+……Niji。是什么意思？

Each layer is the domain based on the number of layers, layer evenly divided, respectively (i.e. , the first layer I is divided into Part I on average, and they are to sink to the center, as in figure 1 (2), as shown below, to form a grid, each grid deployment within the sense node will be a static

Will the layer domain pursuant to by Department layer of layer number, respectively for average Division (that subsection I layer average Division for I part, and are to sink for circle for Division, as Figure 1 (2) by as shown in the), thus formed one by one network cell, each network cell within d
