| 摘要 |
The invention concerns a porous wall (62) through which a gas flow is produced forming a film (18) for levitation of a liquid volume (17) with reinforcing elements (63, 64) for stiffening it and for controlling the lower shape of the lifted liquid (17). Chambers subjected to different pressure levels (67, 68) can be formed, and optionally, separated by some (63) of said reinforcing elements, to enhance equalisation by reducing pressure in the centre; finally capillary tubes (70) can pass through the plate (62) to take pressure or enable further equalisation of the thickness of the film by a suction device. |
