affine

将有限值赋给有限量。

Assigning finite values to finite quantities.

关于可表示为f(⃑x)=A⃑x+⃑b的函数,该函数将平行线映射为平行线,有限点映射为有限点。

Of or pertaining to a function expressible as f(⃑x)=A⃑x+⃑b (where A is a linear transformation and ⃑b is a constant), which, regarded as a transformation, maps parallel lines to parallel lines and finite points to finite points.

两种材料具有相互亲和性。

Of two materials, having mutual affinity.
