地板和地板基础的所有属性的总和。物理性质包括诸如耐压性，弹性和非弹性形变，耐磨损性，内部隔音性，光滑度和防滑表面等方面。在物理性质方面，必须分别考虑单位面积的载荷和集中载荷。

         Sum of all properties of the floor and floor foundation. The physical properties comprise aspects such as resistance to pressure, elastic and inelastic deformation, resistance to wear, internal sound insulation, smoothness, and skidproof surface. In the context of the physical properties the load per unit area and the concentrated load must be regarded separately.
