1.
The results show that when the content of SiC is in the range from 1%(mass fraction,the same below) to 10%,the attenuation frequency of lossy resonance(f0) shifts to a low frequency as the effective attenuation bandwidth grows,and this effect is stronger when the content of SiC is less than 2%.
结果表明:当SiC质量分数(下同)从1%到10%逐渐增加时,复相材料的损耗谐振衰减频率(f0)随之降低,衰减量也逐渐减小,有效衰减带宽增大;这种现象在SiC含量小于2%时更显著。
