当勾选请求者时，若从外界输入某种货物大于某个值，则火车将会来这里拉货，但是不应该来的。我不是在你的mod里面设置数量的，我是外部输入了，但是勾选请求者毫无作用

Google translate:

When the requester is checked, if a certain type of cargo is input from an external source in an amount greater than a certain value, the train will come here to pick up the cargo, but it shouldn't. I'm not setting the quantity in your mod; I'm inputting it externally, but checking the requester has no effect.

If you never want this station to be a provider, uncheck the provider box. That sets a high provide threshold (2,147,483,647). LTN stations are ALWAYS both providers and requesters. If your available (minus threshold) is ever positive, the station will advertise availability and trains may come to pick up.

如果您不希望此站点成为供应站，请取消勾选“供应站”复选框。这将设置一个很高的供应阈值（2,147,483,647）。LTN 站点始终既是供应站又是需求站。如果您的可用资源（减去阈值）为正数，则该站点将发布可用资源信息，列车可能会前来装载货物。
