In this research,we first examine 117 students who have not learnt Periodic Function middle school to analyse studentsunderstanding level towards period.

本研究通过对117位初三学生问卷测试作为前测，分析学生在还没有学习周期函数之前，对周期的了解水平。

Model for finding the cryptic period of hydrological time series is proposed. The functions of the model include to apply logarithm transformation for making the sequence more stationary, to construct a corresponding auto-regression model for reducing the herteroskedasticity of residual, to determine the component of the prime period by periodogram analysis.

bstract 本文在讨论水文时序平稳性和异方差性的基础上，提出了检测水文时序隐含周期的模型，即对水文时序设计对数变换序列，提高序列的平稳性；建立相应的自回归模型降低残差的异方差性；通过对所得平稳序列进行周期图分析确定可能的主周期分量。

Diurnal and semidiurnal quasi-harmonic terms are included in the Scheme Ⅱ.

方案Ⅱ则包含长周期、全日、半日周期的准调和项18项。

Results show that there are multi-time scale periodic variations in AOI, the temperature and precipitation in Northwest China with significant syntonic periods of qausi-3 a between AOI and the precipitation, while the multi-time scale correlations between AOI and the temperature are quasi-2 a, 3-5 a and about 8-11 a with the strongest coherency in 8-11 a syntonic period. The influence of AO on temperature is more remarkable than that on precipitation in Northwest China for the interaction of their interdecada1 variation.

结果表明，AOI、西北地区降水和气温变化都存在着不同尺度的周期振荡，西北地区降水与AOI之间存在准3 a尺度的显著共振周期，而AOI与西北地区气温变化的多时间尺度相关表现为准2a、3~5 a和8~11 a左右的显著相关振荡且以8~11 a共振周期的凝聚性最强；AO对西北地区气温变化的影响比对降水的影响更显著，与其年代际尺度的相互作用有关。

In chapter 2, we form the system info of theory of finance cycle by deep analysis.

The environmental impact during production, usage and residual period of arsanilic acid was assessed in viewpoint of life cycle.

本文介绍了最常用的有机胂制剂－对氨基苯胂酸的主要用途和污染特征，从生命周期的角度识别并定量评价了其生产、使用和残留过程的环境影响，评价结果表明对氨基苯胂酸在土壤中最终残留的环境影响占其整个生命周期的99%以上，指出了常规环境影响评价在评价其环境污染上的局限性，据此提出逐步减少或禁止有机肺制剂的生产和使用、并在一些特殊的建设项目环境影响评价中推广生命周期评价的建议。

But the result of life cycle assessment shows that paper has not the advantage of plastics in environmental protection.This paper analyses and assesses both Plastics and paper package materials using sumple life cycle matrix.

然而生命周期的评价结果表明，纸在环境保护方面并不具有优势，本文采用简式生命周期矩阵对这两种包装材料进行了分析和评价。

When the Roman Church altered the Easter cycle from the old computation on a basis of 84 years to the new cycle of 532 of Victorius Aquitaine in 457, the Gallican Church, unlike the Celts, did the same; but when, in 525, the Roman Church adopted the 19 years cycle of Dionysius Exiguus, the Gallican Church continued to use the cycle of Victorius, until the end of the eighth or beginning of the ninth century.

当罗马教会改变了复活节周期从旧的计算的基础上， 84岁的新一轮的532 Victorius阿基坦在457的高卢圣教会，不同的是凯尔特人，也做了同样的；但是当在525 ，罗马教会通过19年周期的狄奥尼修斯艾克西古斯的高卢圣教会继续使用周期Victorius ，直至第八或年初的9世纪。
