View system including partials and collection support.

视图系统，包括对局部视图和集合视图的支持。

OK, so it's the vector whose components are the partials.

这个向量的所有分量就是这些偏导。

OK, and so the coefficients of dx and dy are the partials.

那么dx和dy前面的系数就是偏导数。

Well, the gradient is also a way to package partials together.

同样地，梯度也是把偏导数糅合到一起。

RoR assumes that partials are named with a leading underscore.

RoR假设片段命名时使用一个前导下划线。
