(Zoology) In certain birds and mammals, one of two or more color variations characteristic of the species, but independent of the ordinary seasonal and sexual differences, and often also of age.

Phase rule (Physics Chem.) A generalization with regard to systems of chemical equilibrium, discovered by Prof. J. Willard Gibbs. It may be stated thus: The degree of variableness (number of degrees of freedom) of a system is equal to the number of components minus the number of phases, plus two . Thus, if the components be salt and water, and the phases salt, ice, saturated solution, and vapor, the system is invariant, that is, there is only one set of conditions under which these four phases can exist in equilibrium. If only three phases be considered, the system is univariant, that is, the fixing of one condition, as temperature, determines the others.
Phase splitter (Electricity) A device by which a single-phase current is split into two or more currents differing in phase. It is used in starting single-phase induction motors.
Phase splitting (Electricity) The dephasing of the two parts of a single alternating current in two dissimilar branches of a given circuit.
