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

neutral axis n. (a) Optics either of two mutually perpendicular directions within a plate of a birefringent substance, such that light polarized parallel to either of these directions is transmitted without change of polarization; (b) Mechanics the line or plane containing those points at which no extension or compression occurs when a beam, plate, etc., is subjected to stress.
