因此，这些材料就可以阻挡以热量形式存在的声子，并将它们反射回去。
That allows the material to block and reflect back the phonons in the form of heat.
基本的单极子天线由于其本身的特性会在天线内部对馈入的信号进行多次反射，严重制约着它的辐射性能。
According to the specific characteristics of monopole antenna, feeding signal may be multi reflected at the terminals, which could seriously damage the radiation characteristics.
最初的井眼成像依赖于单极子源并侧重于分析反射回井眼的辐射纵体波。
Initial borehole acoustic imaging relied on using the monopole source and focusing the analysis on the radiated compressional body waves that were reflected back to the borehole.
