摘要：
We describe the influence of superimposed deterministic and stochastic electric fields on electrohydrodynamic convection in nematics. Multiplicative noise leads to complex spatio-temporally fluctuating patterns. We measure the thresholds for the onset of electroconvection, construct stability diagrams and compare the results to theoretical predictions.
