摘要：

Avalanching powder is a non-linear system which falls within a branch of the modern science known as deterministic chaos. The pattern of events generated by an avalanching powder can be described using the concepts of fractal geometry. The basic theory of these new techniques for characterizing the flowability of a powder by avalanching studies is outlined. Two different instruments: a ramp for Bow studies and a rotating disc for studying avalanches are described. Data characterizing the effect of particle size, humidity, and flowagents on the flowability of powders is presented. The usefulness of angle of repose measurements is discussed.
