英语很烂求帮忙
This is the amortized cost of feedback in units of foregone symbols.
Note that higher layers cannot tolerate an arbitrary increase in latency
caused by excessive aggregation,so one can never drive the cost
of feedback to zero.Suppose that nf already takes into account
as much amortization as is possible subject to higher-layer latency
constraints.

答案

这是反馈摊销成本的预先象征,既然高层不能容忍因过度聚集而长生潜在因素使其任意增长,所以没有人能迫使反馈到零,假设NF想尽可能多的分期偿还将会受到高层的潜在约束的.
