In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.

中国物流统计数据缺乏，客观上限制了对其周期规律的研究，本文选取社会物流总额作为测度指标，设计了一种人工序列，解决了统计数据过短问题；谱估计法从频域角度揭示客观事物的时间特性，在研究时间序列周期波动方面具有时域分析法所不具备的优势，作者采用谱估计法对中国物流发展周期进行测定，检验了指标序列平稳性，分析了截断点参数灵敏度，比较了6种不同滞后窗下周期值，并检验了所测得周期的显著性。

In this algorithm, by initially setting a larger threshold of rate-distortion slope and marking the channels that their rate-distortion slopes are larger than the thresholds in each coding block as "selected state", and then decreasing the threshold step by step until the sum of the rate of those selection exceeds the predefined rate limitation, an approximate optimal truncation point will be obtained.

本算法通过初始设置一个较大的长度－失真斜率阈值，将每个编码块中长度－失真斜率大于该阈值的通道置为"选入"状态，逐次减小该阈值并重复上述过程，直到状态为"选入"的通道的累积码流长度大于设定的码流长度，得到近似的最优截断点，再采用舍弃最小斜率的方法获得最优截断点以实现码率控制。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.
