| Abstract: | A set of experimental device for measuring pressure screening effect is presented.The experimental data can completely exhibit the distinct difference between the granular matter and the liquid.The experimental results are in good agreement with the theoretical calculation,which show that the pressure screening effect results from the great effect of friction between the grains and the container wall. |

| Keywords: | pressure screening effect granular materials friction apparent mass |
