请高手翻译一下如下说明，谢谢！

Enter tray numbers and corresponding efficiencies in the table provided.  Note that efficiencies are considered to be provided for ranges of trays.  Therefore, trays which do not have supplied efficiencies but are bracketed by trays with supplied values are assigned values determined by linear interpolation.  Trays which do not have supplied values and are not bracketed by trays with supplied values are assigned efficiencies of 1.0.  The condenser and reboiler trays are always assigned efficiencies of 1.0.上文是有关塔盘效率的问题，请高手说明，谢谢！

字面意思是要求输入塔板数和相应板效率，并请注意板效率是分段定义的。未提供单板效率，但是属于段内的（已定义效率），采用内插法确定板效率；未提供单板效率，不属于段内的（已定义效率），认为其效率为1。再沸器和冷凝器效率为1。

非常谢谢！
