[ noun ] any distinct time period in a sequence of events
Synonyms Examples "we are in a transitional stage in which many former ideas must be revised or rejected" Used in print (The Christian Science Monitor,...)You will need a stereo music system , with speakers preferably placed at_least seven or eight feet apart , and one or more of the new London `` Phase 4 '' records . London explains that the very distinct directional effect in the Phase 4 series is due in large part to their novel methods of microphoning and recording the music on a number of separate tape channels . (Edward Austin Walton, "On Education for the Interior...)In the earlier years of training certain phases of the work must be covered and the synthetic problem has its use . (Handbook of Federal Aids to Communities. U.S. Dep...)One-day conferences covering some specific phase of business management , also part of the continuing activities of the Small_Business_Administration , aid community economic development programs . (Cornell H. Mayer, "Radio Emission of the Moon...)In the observations at 4.3 mm ( Coates , 1959 a ) , the diameter of the antenna beam , 6 ' .7 , was small enough to allow resolution of some of the larger features of the lunar surface , and contour diagrams have been made of the lunar brightness distribution at three lunar phases . |

[ noun ] (physical chemistry) a distinct state of matter in a system; matter that is identical in chemical composition and physical state and separated from other material by the phase boundary
Synonyms Examples : "the reaction occurs in the liquid phase of the system" Used in print (Nathan Rapport, ""I've Been Here before!"...)So we may conceive the coexistence of the infinite number of universal , apparently momentary states_of_matter , successive one_after_another in consciousness , but permanent each on its own basic phase of the progressive frequencies . (Jay C. Harris and John R. Van Wazer, "Detergent...)In an essentially static system , an oil cannot be replaced by water on a surface unless the interfacial_tensions of the water phase are reduced by a surface-active_agent . ( 3 ) For anionics , these micelles appear to be roughly spherical assemblages in which the hydrocarbon tails come together so that the polar groups ( the ionized ends ) face outward towards the aqueous continuous phase . Obviously hydrophobic ( oleophilic ) substances such_as greases , oils , or particles having a greasy or oily surface are more at_home in the center of a micelle than in the aqueous phase . Related_to micelle formation is the technologically important ability of detergent actives to congregate at oil_water_interfaces in such a manner that the polar ( or ionized ) end of the molecule is directed towards the aqueous phase and the hydrocarbon chain towards the oily phase . |

[ noun ] a particular point in the time of a cycle; measured from some arbitrary zero and expressed as an angle
Synonyms Used in print (Cornell H. Mayer, "Radio Emission of the Moon...)The infrared_emission could then be assumed to originate at the surface of the moon , while the radio_emission originates at some depth beneath the surface , where the temperature variation due_to solar_radiation is reduced in amplitude and shifted in phase . |
