中文摘要：
对二维组合开缝金属圆管的禁带特性进行了数值模拟和实验验证,着重研究了缝参数对禁带的影响,并分析了不同缝参数开缝圆管组合结构具有的独特禁带性质.模拟计算和实验结果符合较好,结果表明这种微缝带隙结构具有起始频率低的特点.同单一缝参数开缝圆管带隙结构相比,组合缝参数带隙结构具有连续的大禁带.
英文摘要：
The band gap of two-dimensional metal tube structure with multi-width narrow slits is simulated and verified experimentally. The unique properties of the stop band exist in the band gap structure with combined parameters of slit tubes. It is found that the band gap of this structure is large and the starting frequency is low. In contrast to the band gap of the structure with narrow slits, the stop band of the combined structure of the parameters of the slits is continuous and large.
