  频响特性
    When the heat-treatment temperature is 650 C,the tangent of dielectric loss angle of the fiber approachs to 1, and the frequency response characteristic is fine from 2GHz to 18GHz . In the heat-treatment ambience, the vapor is the most important factor, and reducing the vapor can make the electromagnetic properties more steady.
    经过650℃热处理的纤维,介电损耗角接近于1,在2GHz—18GHz频率范围内具有较好的频响特性

To investigate the dynamic characteristics of the elastomers, a series of Hopkinson's bar experiments were performed. From the experiment results it was found that with different ratios of length, diameter(L/D) and different hardness, an elastomer exhibits different cut-off and nature frequency characteristics. A mathematical model of the frequency response function for cylindrical elastomeric specimens has been developed. This model can be used as the basis for a computer-based...

To investigate the dynamic characteristics of the elastomers, a series of Hopkinson's bar experiments were performed. From the experiment results it was found that with different ratios of length, diameter(L/D) and different hardness, an elastomer exhibits different cut-off and nature frequency characteristics. A mathematical model of the frequency response function for cylindrical elastomeric specimens has been developed. This model can be used as the basis for a computer-based routine which is able to simulate frequency response characteristics i.e. filtering ability of given size and hardness of elastomeric specimen. The simulation results agree with the experiment results which indicate that the elastomer with this dynamic characteristics can be utilized as mechanical filter.

为了研究合成弹性材料的动态特性,利用Hopkinson棒装置进行了一系列试验。试验结果表明,具有不同长度与直径比和不同硬度的合成弹性材料具有不同的截止频率和固有频率。建立了圆柱形合成弹性材料试件的数学模型,并以此作为计算机程序的基础对给定尺寸和硬度的圆柱形合成弹性材料的频率响应特性进行了仿真,仿真结果与试验结果一致,说明具有该动态特性的合成弹性材料可以起到机械滤波器的作用。
