additional wall layer的意思|示意

Designed as a box inside a box, the solid inner wall reduces thermal conductivity while the exterior layer provides additional energy efficiencies.

建筑被设计为一个盒子内嵌一个盒子的形式，内部的实心墙降低了导热系数，而外层提供了额外的节能效果。

And in the design of the additional layer of the noise-damping tower, the light-weight steel framework, the light-weight wall body and the rubber isolating layer are adopted to extenuate the shaking.

在加层设计中，有效地运用了轻钢结构体系、轻质墙体和橡胶垫隔震层来减轻震动的作用。
