规模经济的中心思想就是为达到高效率从而降低单位成本，而进行的通过标准化批量生产所采用的最佳方法。

Central to the concept of economies of scale is the idea that the best way to achieve high efficiency, and hence low unit costs, is through the mass production of a standardized output.

据此逻辑，提高效率而压缩单位成本的方法就是限定产品种类，并且进行标准化批量生产。

According to this logic, the way to increase efficiency end drive down unit costs is to limit product variety and produce a standardized product in large volumes.

如果想用单位法向量来计算通量，还得先把它标准化到单位长度？

Now, if you wanted the unit normal vector to compute flux, then you would just scale this guy down to unit length, OK?
