| 释义 | † surdesolid, n. (a.) Math. Obs.
Also surdsolid.
[ad. mod.L. surdesolidus. Cf. It. surdesolido, G. † surdesolidalisch.
The origin of mod.L. surdesolidus is obscure. In Zedler's Universal Lexicon, s.v. Dignitas, the term is given as the name of the 5th power ‘according to the Arabs’, corresponding to quadratocubus, the name ‘according to Diophantus’; the 7th power is surdesolidum secundum, and the 11th surdesolidum tertium. If the term is of Arabic origin, it may = *surdē solidum, lit. deafly solid, i.e. of a power not ‘communicating with’, i.e. not derivable from, 2 or 3 or their powers (cf. the origin of mathematical L. surdus, surd a. note).]
= sursolid.
