英语词汇“helmholtz resonator”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

Helmholtz resonator n. (also Helmholtz' resonator, Helmholtz's resonator) [described by Helmholtz in 1859 in Gelehrte Anzeigen der Königl. Bayerischen Akad. der Wissensch. 48 553] Physics a hollow object designed to have a strong resonance at a particular pitch and no other significant resonances.As invented by Helmholtz it consisted of a hollow sphere with a short narrow neck. The resonant frequency depends on the volume of the sphere and the length and area of the neck.
