2) attenuation frequency
衰减频率
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。

6) frequency decay
频率衰减特性
1.
Generally speaking,it is caused by the difference between the equilibrium and the frequency decay,which is difficult to be controlled.
通常认为均衡特性和频率衰减特性的差异是造成这种现象的主要原因,很难抑制。
