研究了使用液晶N4的电对流作为两个控制参数的函数：外加频率和外加电压。作为电压的函数，存在一系列丰富的分叉，将系统从静止滚动带到混沌。作为频率的函数，初始模式从低频下的静止斜辊变为高频下的静止正常辊。二次分叉也发生了变化。特别是，我们观察到随着施加频率的增加，双峰曲张不稳定性被歪曲曲张不稳定性所取代。并与理论预测进行了比较。
Electroconvection using the liquid crystal N4 is studied as a function of two control parameters: the applied frequency and the applied voltage. As a function of voltage, there is a rich series of bifurcations that takes the system from stationary rolls to chaos. As a function of the frequency, the initial pattern changes from stationary oblique rolls at low frequencies to stationary normal rolls at higher frequencies. There is also a change in the secondary bifurcations. In particular, we observe that the bimodal-varicose instability is replaced by the skewed-varicose instability as the applied frequency is increased. Comparisons with theoretical predictions are made.
