喜樂美語
  1. 1（數學／程式）不變量、不變式

    Something that stays exactly the same no matter what else changes around it. Mostly a technical word from math, physics, and computer science — for example, a quantity that stays the same throughout a calculation, or a condition in a computer program (a 'loop invariant') that must stay true every time the loop runs.

組成in- ("not") + vary ("to change") + -ant.
