In general, metal foams are useful for high-tech shock and impact absorbers, the gas inside makes them extremely compressible, so they can absorb a lot of mechanical energy, while still retaining some of the strength and durability of a metal.

总之，金属泡沫对高科技震动和压力吸收的帮助很大，内部气体让物质极度压缩，可吸收很多机械能，而且依然保留金属的强度和耐用性。
