After sonication, the emulsification capacity and the foam ability of SPI were improved, and the emulsification stability of soybean crude 7S and 11S protein were also increased.

Using drainage ability strong permeability foam concrete can be as light, the gravel based on in or artificial turf, as a playground use.

The influence of temperature, gas-liquid ratio, gas-liquid rate, residual oil saturation and permeability on steam foam sealing ability is studied on the basis of microscopic percolation study.
