In this experiment,the formation of Faraday pattern in xanthan gum solution driven by high frequency
periodic external force is studied.The experimental results show that the critical parameter of pattern generation,
the maximum driving acceleration,has a quasi linear relationship with the driving frequency.Further semiquantitative
theoretical analysis shows that this result may be related to the balance of the energy dissipation caused
by viscosity and the energy input of the external driving force,and the maximum velocity of solution surface may be
the key characteristic quantity affecting the pattern generation.
