We first treated the wood with creosote. 我们先用杂酚油对木柴进行了加工处理。
But because it does not need to receive further treatments a shed made from treated wood would not need regular applications of creosote, for example it should prove economical over its lifetime. 但是由于它不需要进行进一步的加工,从整个使用过程来说还是物有所值的。比如使用经加工的木材建造的棚子可以免于定期维护。
