Abstract: The characteristics of the transparent wall is researched in pressurized condition with theoretical and experimental methods. It is cleared the influences of the wall structure and the material of film for the transmittance. Transmittance is decreased with the thick layer wall. It is influenced very large with the size of the film and the pressure. The film characteristics, the density and Young modulus, hardly vary the frequency characteristics of the transmittance, but change the vibration mode of the film and vary the transmittance. The film of low density and low Young modulus makes the large transmittance.
