另外一些公司，比如富士康，则需要依赖可以迅速对设计做出改变的当地供应商组成的闭合网络，这样一个网络不可能迁移到别处。

Others, like Foxconn, rely on a close network of local suppliers who can react quickly to design changes - a network that cannot be moved elsewhere wholesale.

Farhana：并且你的身体对修改是闭合的。

Farhana: And your body is closed for modification.

这个就是散度公式了，告诉大家一些相似的东西，仅仅是对被闭合曲面包围的空间区域来讲的。

This one here, the divergence theorem, tells you something similar but now for a region of space bounded by a closed surface.

If you have a quantity which is constant over any closed path, that quantity is a thermodynamics state function.

如果有一个物理量,对任何闭合回路积分是常数，这个物理量就是一个热力学态函数。
