In this work, a model of cellular structures in thermal fields has been established based on methods of material mechanics, structural mechanics and thermodynamics. Cellular structures have different deformation behaviors in thermal environment with different coefficients of thermal expansion (CTE), the desirable equivalent coefficient of thermal expansion (ECTE) of cellular structures can be achieved by introduce members with different CTEs. Three different configurations are proposed to study the relationship between ECTE and geometrical configuration. The results show that: desirable ECTE can be obtained by designing configuration shape of cellular structures, inclined angle of members and positions of different CTE materials.

在这项工作中，已经基于材料力学，结构力学和热力学方法建立了热场中的细胞结构模型。蜂窝结构在具有不同热膨胀系数（CTE）的热环境中具有不同的变形行为，通过引入具有不同CTE的构件可以实现蜂窝结构的理想等效热膨胀系数（ECTE）。提出了三种不同的构型来研究ECTE和几何构型之间的关系。结果表明：通过设计蜂窝结构的外形形状，构件的倾斜角度和不同的CTE材料的位置，可以获得理想的ECTE。
