摘要：
The helical pitch as a function of low-frequency ac electric field at different temperatures has been investigated in a ferroelectric liquid crystal both experimentally and theoretically. A simplified model has been presented to calculate the variation of helical pitch under such fields, and the results obtained are in good agreement with the experiment. The frequency dispersion of the pitch has also been measured.
