这个蓝图是 "<140.4>现代工业 Modern Industry" 这个蓝图合集大型硅蓝图里最实用的一个了。32联相比之下太大了，但凡资源穷一点或者地形狭窄狭窄一点的图就很难建造起来。
This blueprint is the most practical one of the large silicon blueprints in the collection of "<140.4>Modern Industry" blueprints.
The 32 couplets are too large in comparison. It is difficult to build maps with limited resources or narrow terrain.
