摘要

By laboratory experiments, we investigate instability behaviors in a differential rotation system derived from the Czochralski silicon crystal growth. The experimental apparatus consists of a rotating disc (radius a, rotation rate omega) on the surface of homogeneous salt water contained in a rotating cylindrical tank (radius R>a, rotation rate Omega
