This paper introduces a novel approach of HFR, which is based on minimum entropy.

提出了一种基于最小熵的方法进行高频重建，试验结果表明重建声音主观听觉良好。

Although some new funds have been created, HFR reckons there were just 8, 860 funds at the end of March, down from 10, 096 in 2007.

尽管期间有部分新基金成立，根据对冲基金研究的计算结果，截止至三月末，仅剩8860家对冲基金，而2007高点时为10096家。

The proposed invention offers a low-complexity, intermediate quality HFR method useful in speech and natural audio coding applications.

本发明提供一种可应用于语音和自然音频编码的低复杂性，中级质量HFR 方法。

Figures from Hedge fund Research (HFR), a consultancy, show that the average fund gained 5. 2% in May, the best monthly performance since 2000.

咨询公司，对冲基金研究(HFR)的数据显示各基金五月平均收益为5。2%，是自2000年来表现最好的一次。

The worst year for the sector, according to HFR, was 2002, when the index fell 1.5%; there has been only one month since 1990 when the sector lost more than 3.5%.

按照HFR的说法，这个行业最差的一年是2002年，当时指数跌了1.5%，而且自1990年以后只有一个月这个行业的损失超过3.5%。
