| 摘要 |
The wall (10) to the inner-room has over at least 20% surface cavities (2) which do not extend longitudinally. The wall does not have any cavities on the outside, or the inner cavities have twice the volume of the possible cavities on the outer-room. The inner cavities are rounded in their base section and have a depth of 15%-85% of the wall thickness (S). The remaining depth (SR) is at least 0.5 mm.
