This paper preliminarily analyzed the advantage of a reactor core with rod type element in tight triangle lattice, and briefly introduced its application in small and medium nuclear power plants.
The modal characteristics of dual core photonic crystal fibers(PCFs) are analyzed by a full vector supercell lattice overlapping model.
应用全矢量超格子叠加模型分析了双芯光子晶体光纤（PCF）的模式特征。

The data are reduced using the concept lattice attribute reduction method, and thus the core attributes, relative necessary attributes and unnecessary attributes for fault diagnosis are obtained.
