adjective ˈpɒlɪfeɪzˈpɑliˌfeɪz

1Consisting of or occurring in a number of separate stages.
多级的
a polyphase tectonic interpretation
Example sentencesExamples
- New palaeomagnetic data from Lower Carboniferous granitoids of the orogenic root of the eastern Variscan belt show a polyphase palaeomagnetic record.
- The Arunta Inlier is an extensive east-west-trending, polyphase, high-grade, predominantly Palaeoproterozoic metamorphic complex.
- Precambrian metamorphism and migmatization and the wide spectrum of mainly Alpine mica ages provide clear evidence for such a polyphase geological history.
- The Moine rocks widely record polyphase deformation and metamorphism up to amphibolite facies.
- The polyphase tectonic and sedimentological development of East African continental rift basins is well-illustrated in the Kilombero Rift Valley in Tanzania.
1. 1.1 (of an electrical device) simultaneously using several alternating currents of the same voltage and frequency but with different phases.
  （电气设备，电路）多相的
  a polyphase induction motor
  Example sentencesExamples
  The Energy Policy Act of 1992 required minimum efficiency standards for general purpose, polyphase induction motors.
  The reduction in the die area dedicated to capacitance opens up the possibility of building more complex RF circuits, such as image-reject mixers and polyphase IF filters.
  In contrast to direct current (which was difficult to transmit more than ten miles), polyphase AC systems proved capable of transmitting power hundreds of miles.

Derivatives

polyphasic

adjective

Electromyography may show short-duration, small-amplitude, polyphasic motor units with an increased terminal innervation ratio (number of fibers innervated by a single anterior horn cell).
Example sentencesExamples
- The blink reflex was characterized by an initial triphasic wave on the ipsilateral stimulus side, followed by a polyphasic wave on both sides.
- It has been demonstrated that when a dark-adapted leaf is illuminated with high intensity actinic light, the fluorescence transient shows a polyphasic rise, including phases O, J, I, and P.
- Isolates underwent polyphasic analyses employing phenotypic (selective media and biochemical testing) and genotypic (polymerase chain reaction) assays to determine species identification.
- But he had no scientific proof that, in situations of sleep deprivation, polyphasic sleep - the term for frequent napping - was more efficient than monophasic (getting sleep all in one chunk).
