Question

求助:航空发动机里的专业英语中,"Out of roundness"如何翻译.

该词组所在原文为: Out-of-roundness , (OOR) ,is assumed to be the circumferential variation from the intended geometry in an otherwise symmetrical plane . This effect can be induced in a number of ways both thermally and mechanical . Unbalanced local thermal gradients ,single air off takes from a circumferential casing bleed , and circumferentially varying environmental conditions can all contribute to out-of-roundness of the linings from thermal effects. Split casings , shrouded stator split lines , engine primary structure distortions transmitted to the lining support are example of mechanically induced OOR.
