建立了二维超导光子晶体的物理模型，在超导二流体模型并考虑原子作非简谐振动情况下，用平面波展开法求出超导光子晶体的光子能带满足的方程.以YBaCuO超导光子晶体为例，探讨温度对它的光子能带结构的影响.结果表明：二维超导光子晶体在低温时具有较宽的禁带，且禁带宽度随温度的升高而变小.

The physical model of twodimensional suerconducting photonic crystal is established. Taking atomic nonharmonic oscillation into account with the help of twofluid model, the equation of photonic band structure is obtained using the method of plane wave expansion. Taking a superconducting photonic crystal YBaCuO as example, the influences of temperature on the photonic band structure are analyzed. The calculations show that the twodimensional photonic crystals have the wider band gaps at the lower temperature, which narrows with the increases of temperature.
