Abstract
The mechanical parameters of grains in partial region in China,such as internal friction angle,friction coefficient in relative to the silo wall(concrete and steel plate),angle of natural repose,was tested by use of the independently developed apparatus.The influencing factors,such as water content,particle size and regional difference,were analyzed.
