Based on the research of body decoration on the ceramic wine bottle made with Yellow River silt,a series of semi-frit glaze was made.

Ceramic slurry mainly containing the Yellow River silt,a natural waste,was successful prepared for the slip casting use,which were more than 60%(in mass,the same below) of silt.

The raw material Yellow River silt is one sort of natural waste, which belongs to the silicate mineral material and meanwhile a utilizable precious resources, Manufacturing wine bottle with Yellow River silt can not only benefits the environment, but also economize cost.

By adding high molecular weight flocculants intohigh turbid concentration suspensions with Yellow-River sediments,and by using settling technique and image analysis technology.

Through the variation analysis of runoff and sediment transport capacity of Qiushuihe River from 1954 to 2000,the flow-sediment relationship of the river has shown a great change since 1978.

Combined with the optimum regularizafion technique inverse algorithm,the particle size distributions of sediments under different volume fractions and different particle size distribution were obtained according to the attenuation prediction of coupled-phase model plus a scattering model and experimental attenuation spectrum at fre- quencies ranges from 2 MHz to 7.
