| 释义 | > as lemmasreflection oscillator reflection oscillator n. Electronics (a) a valve oscillator having two closely-spaced grids with an alternating electric field between them, through which electrons pass twice, once in each direction; (b) an oscillator consisting of a resonator (a tuned circuit) and an active device such as a transistor connected in such a way that instability in the latter causes oscillations to build up in the former until stability is reached. ΚΠ 1946 Proc. Physical Soc. 58 476 A working model equivalent to a reflection oscillator has been made, using a balanced horizontal arm. 1947 J. G. Crowther & R.
