它能把路由器的能量汇聚到一个方向——朝着房子的另一端——而不是分散到整个环形空间。
Metals such as aluminum can also form foams -- and because of their greater rigidity, they could, in theory, dissipate as much energy as a polymer foam in a much thinner layer.
金属,如铝,也可以制备成泡沫材料。 由于金属更高的刚度,理论上,更薄金属泡沫就可以吸收聚苯乙烯泡沫所能吸收的能量。
But this did not dissipate the shockwave's energy.
