Finally, an approximating formula which is applicable for the whole frequency range is given.
最后给出了在全频率范围适用的声阻率近似公式。
The whole frequency is low to slice, and can produce the clean music, and can nicely protect the trumpet of good whole frequency;
全频低切,能产生干净音乐,并能很好地保护好全频喇叭;
The results show that (1) the modal radiation efficiency increases with the increasing of the frequency in the whole frequency range;
结果表明:(1)圆板的模态声辐射效率在全频段内大体呈现随着振动频率的增高而增大的特点;
