添加了一种关联管,放下关联管后需要在关联管的界面选择关联管储存的液体,关联管将尽力保持管内液体在75%，超过则收入虚空缓存，少于则从虚空缓存中放出,通常液体都可兼容，除非该液体传输的温度与默认温度不同。若想添加非默认温度的液体，可以在prototypes\templates.lua中照例修改。
目前暂时不要用关联管的尾部对着其他的输入端，否则极有可能失效。
Add a link pipe. After you put down the link pipe, the liquid stored in the associated tube needs to be selected in the interface of the link pipe. The link pipe will try to keep the liquid in the pipe at 75%. If it exceeds the limit, it will be included in the cache, and if it is less than the limit, it will be discharged from the cache. Generally, mod's liquid is compatible, unless the transmission temperature of the liquid is different from the default temperature. If you want to add a liquid with a temperature other than the default temperature, you can modify in prototypes\templates.lua.
At present, do not use the tail of the link pipe to face other input terminals, otherwise it is very likely to fail.
