英语词汇“half-wave rectification”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

half-wave n. one-half of a complete wave, esp. of electricity or radiation; freq. attrib., utilizing only alternate halves of a sequence of waves, as half-wave rectification ( Chambers's Techn. Dict. 1940); half a wave-length long, as half-wave antenna, half-wave dipole, etc.

ΚΠ

1904 G. F. Goodchild & C. F. Tweney Technol. & Sci. Dict. 278/1 Half wave plate, a plate of doubly refracting crystal, capable of splitting up a plane polarised ray into two portions, one of which is retarded half a wave length with respect to the other.

1912 Motor Man. (ed. 14) ii. 33 When the platinum contacts at the end of the armature touch, one-half of every complete wave flows into the accumulator, and when the contacts separate, the reverse wave of the current is interrupted at the zero or no-voltage line; thus only the half-waves of current flowing in the same direction are used.

1926 R. W. Hutchinson First Course Wireless viii. 145 If the first half-wave is positive the grid will become positive.

1926 R. W. Hutchinson First Course Wireless viii. 145 The next half-wave is negative and this still further lowers the potential of the grid.

1928 Morning Post 6 Feb. 3/4 A half wave rectifier.

1943 Gloss. Terms Telecommunications (B.S.I.) 67 Half-wave dipole, a straight aerial symmetrical in regard to its standing-wave current and usually approximately half a wavelength long.

1962 J. H. Simpson & R. S. Richards Physical Princ. Junction Transistors xii. 276 The same is true of any amplifier, such as the Class AB, whose output is asymmetrical and consists of pulses that are larger than one half-wave.

1962 D. R. Corson & P. Lorrain Introd. Electromagn. Fields xiii. 446 After having mastered the electric dipole, we shall be able to study the radiation field of the half~wave antenna—the type commonly used for transmitting radio waves.

half-wave rectification n. Electronics the conversion of an alternating input into direct current output by a circuit, device, or component that passes current in one direction only.

1915 Gen. Electric Rev. Mar. 164 (caption) Half-wave Rectification, Upper Curve Gives Voltage Over Kenotron.

2020 K. Robinson Pract. Audio Electronics v. 60 One diode on its own easily achieves half wave rectification.
