把这一句，留给此刻的你

I regard it in fact as the great advantage of the mathematical technique that it allows us to describe, by means of algebraic equations, the general character of a pattern even where we are ignorant of the numerical values which will determine its particular manifestation.

事实上，我认为它是数学技术的一大优势，它允许我们用代数方程来描述一个图案的一般特征，即使我们不知道决定其具体表现形式的数值。
