释义 | > as lemmasout of phase (with) a. Physics. A particular stage or point in the cycle of a periodic phenomenon (esp. an alternating current or a light wave), or in a recurring sequence of changes or movements, considered in relation to a particular reference position or time, or to the state of another cycle or system with which the first may or may not be in synchrony. in phase (with), having the same phase (as); in the same stage of variation at the same time (as); in synchrony (with). out of phase (with), not in phase (with). Also in extended use.
