摘要：

The convection cell described consists of a nematic liquid contained between two closely spaced parallel plates that are maintained at different temperatures. Sensitive circuitry detects any change in the cell capacitance and feeds back an AC voltage that holds the molecules at a constant angle and thus a constant capacitance.
