In a color-matching task where the cognitive goal is color constancy, environmental illuminant color temperature was used as a cue for the subjects and treated as an independent variable while not affecting the viewing of the target itself. The subjects' color constancy performance was then treated as the dependent variable.

It's an effective measure of fast valving in improving the dynamic stabilities of power system and preventing the overspeed of steam turbines, but the fast valving technique available can satisfy the need of modern steam turbines no more. On the basis of the new type fluid logic valve, which combines the regulating systems and safety systems happily, the steam turbine EHC based on new principle is put forward, one of its outstanding characteritics is, the fast valving is operating in a closed control loop. For the implementation of control for steam generator regulation and safety systems with nonlinear mult-operating modes, a new methodology for designing a fuzzy logic controller is proposed, which is based on the combination of"error phase plane"and"variable universe of discourse". Application of a double-mode FLC with the new methodology is presented, the validity of the design methodolody is desmonstrated by test; A new methodolody is also presented to improve the design and tuning of a FLC using variable structure control theory.
