This paper is expanded into three main parts to study and analyze the stock time series.1 Through the normality tests, All the sample stock-data curves show different phenomenon of Aiguille and Fat-tail, as well as Left-Deviation, which proves that none of the sample series belong to normal distribution, in other words, the linear method can't be applied into the analysis process, so we adopted the R/S method instead.2 The application of R/S method has verified the long-term memory characteristics of the sample series, and Support Vector Regression is combined to enhance the precision of Average circle period.

文中对股票时间序列从以下三个方面进行了研究和分析：1通过正态性检验，发现各样本股票数据均表现出不同程度的尖峰和胖尾以及左偏现象，证明了所有的样本序列全都不属于正态分布，也就是说明它们不能够适用线性方法进行分析，必须采用重标极差分析方法的非线性方法。2应用R/S分析方法验证他们具有长期记忆的特性，并且结合支持向量回归机提高了测定平均循环周期时的精确性。

WSMIS is an end-to-end software system that enables Air Force personnel globally to track the lifecycle of aircraft parts and weaponry.

WSMIS系统是终端对终端的软件系统，能够使空军人员在全球跟踪飞机部件和武器系统的生命周期。

OBJECTIVE: To explore effects of cyclical air-pressure culture on proliferation, activity and cell cycle of rabbit BMSCs.

目的：探讨周期性压力培养对兔骨髓间充质干细胞增殖活性及细胞周期的影响。

In which, first of all, the influence of solid tide whose period is longer than 128 minutes is removed with high-pass filter, and the secondly, air-pressure influence is removed with linear regression method ,and then the signals for 2~128 minutes are decomposed into 6 different kinds of frequency bands with wavelet transform method. The results indicat that wavelet transform can be used to identify small change existed in deformation signal.

用高通滤波消除周期＞128分钟的固体潮汐影响，用回归分析方法消除气压干扰，用小波变换方法将2~128分钟的信号分解到6个不同频段进行分析，结果显示小波变换方法能提取出信号中的微弱变化信息。

This thesis discusses mainly the hardware design and development of a simulator for airborn phase array radar. The long period of the simulator is implemented by SDRAM MODULES used in Personal Computer, the broadband is implemented by D/A with internal double-data-channel switching architecture, and the control is implemented by a single CPLD.

本文主要探讨了一种机载相控阵雷达回波模拟器的硬件设计和工程实现，采用了PC机内存常用的超大容量高速缓存SDRAM MODULES来实现输出信号的长周期，采用内部具有双路数据分时切换结构的D/A实现输出信号的宽带，采用一片CPLD完成整个系统的时序逻辑控制。

Several economic theories are applied in this thesis in the quest to identify the boosters behind the transformation of Taiwan's manufacturing industry and to pinpoint some deficiencies at different major stages of Taiwan's economic development. Among them are: Kaname Akamatsu's Flying Geese Paradigm, Vernon's Theory of the Product Cycle, the Theory of International Division of Industry, Porter's Theory of Stages of Economic Development, etc.

论文中运用了赤松要的产业转移雁行理论，弗农产品生命周期理论，产业的国际分工理论，经济管理大师波特的经济发展阶段论等，在力求阐明促进台湾制造业成功转型动因的同时，也力求找出台湾在各个主要经济发展阶段的一些不足之处。

"It may be that these very young drinkers just haven't lived long enough — or had time to experience the cycle of failure and success — to allow abstinence to work," said Kaskutas, director of training at the Alcohol Research Group in Berkeley, CA.

"可以说，这些非常年轻饮酒者只是还没有住够长-或者没有足够时间进行体验周期的失败和成功-让禁欲的工作，说：" k a skutas主任，训练时，酒精研究小组在伯克利分校钙。

TN91# strain fermentation could increase fermentation speed and improve wine quality and wine alcoholicity by TN91# strain fermentation was as high as 12.8 %, 14.3 % higher than that by parent strain fermentation.

TN91#菌株在发酵周期内酒精度为12.8 %vol，比出发菌株提高了14.3 %，且该菌株在起酵速度及增加果酒品质方面都有提高。

This "Mayan" cycle also corresponds to a 26,000 year relationship of the Sun orbiting Alcyone, the central star of our Seven Sisters Pleiades constellation.

这种"玛雅"周期也对应于太阳轨道昴宿六2.6万年的关系，我们七姐妹昴宿星座中央恒星。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
