The wavelet classical theory is used to discuss the behavior properties of share price signals . we show that there are the properties of self - similarity , periodical , and long - term trend in these signals 本文利用小波分析经典理论研究了股价信号行为特征，发现股价信号具有自相似性、拟周期性，和某种长期趋势性。
The sea - ice extent of north arctic undergoes an evident decrease during the last 42 years ( from 1953 to 1994 ) , for which the unusual changes of the spring ( may - july ) north arctic sea - ice extent make the main contribution 北极海冰面积过去42年( 1953 - 1994年)来经历了一种趋势性的减少，春季( 5 - 7月)北极海冰异常变化对此做出了主要贡献。
The author starts from the evolution of general management theory , concludes its trend , analyze the effect that general management has on the taxation management , then points out that taxation culture management should , or must be , a trend 从一般管理理论的演变入手，总结管理内容提要理论演变的趋势性，分析一般管理理论演变对税务管理的影响，进而指明税收文化管理也应当并必将成为一种趋势。
So it is essential to have efficient index system to control and measure the tax resource . by this index system , we can have more information about taxpayer . so we can grasp the rule of tax and administer some important questions to reduce risk of tax imposing 通过建立一套指标体系，可以改善税务机关信息不对称的状况，建立有效的涉税信息库，把握纳税行为的规律，加强对重点问题和趋势性问题的治理，以减少税收征管的风险。
An improved ar model is studied , which established by the combination normal order time serial and contrary order data in case the observations are less , and then , the combination model with improved grey and time serial is introduced . it can reflect not only the deformation tendency , but also the stochastic characters . it is very suitable to be applied to deformation analysis and prediction 为了充分利用有限的地表变形数据所蕴涵的内在规律性，提出了利用变形数据的正逆时间序列建立ar模型的方法，并与时变灰色模型组合，不但可反应出变形数据序列的趋势性，同时还可表现出其随机性，从而可进一步提高预测的精度和效果。
In this thesis the author tries to prove that the wave of price in the stock market is predictable finitely with theory and practice . as a matter of fact , trends , time cycles and price cycles are characteristic of the wave . at the same time , prediction itself cannot provide absolute precision , and it ' s finite 本文从理论和实证上证明股票市场价格波动存在有限可预测性，即价格波动存在趋势性、周期循环和价格循环，同时也指出预测科学本身并不能提供100的精度， “可预测性”是有限的。
( 2 ) some studies are made for the subject of various effects on wave propagation and ground motion of multi - dry , multi - saturated , and alternate dry and saturated soil layers . a comprehensive computer program is compiled , accounting for soil dilatancy , linear and non - linear constitutive relation , rigidity degradation and suiting to any combinations of soil layers , dry and / or saturated with different thicknesses , properties , continuity conditions at interfaces , and inputs at base and top boundaries . from the numerical results obtained for a quite large number of typical cases , some knowledge of general trends of response for , especially , the cases of alternate dry and saturated soil layers are gained both quantitatively and qualitatively ( 2 )对不含水土层分层排列、饱水土层分层排列、不含水土层与饱水土层分层交错排列情况下对波传播和地面运动的影响做了一些研究，考虑到土壤的剪胀性、线性和非线性本构关系，刚度退化等因素，编制了可适用上述各种情况和任意多土层(包括含水或不含水、力学性质不同、厚度不同、边界连续条件不同等) ，在不同基底输入或上边界输入作用下的通用分析程序，通过对相当数量的典型情况进行的分析计算，得到了一些趋势性的认识，特别是对饱水与不含水土层分层交错情况，取得了一些新认识。
Using data from 1978 to 2004 , the paper presents a comprehensive analysis on the time serial change of grain yield per hectare in northeast china from 4 viewpoints of period , trend , steady and crops respectively , and illustrates the different impact factors of agricultural production conditions on grain yield per hectare change at different stage using grey relation analysis 以1978 - 2004年数据为基础，分别从阶段性、趋势性、稳定性与不同作物等4个角度，对东北地区粮食单产时序变化进行了系统分析；并从农业生产条件的角度，对影响东北地区粮食单产变化的因素进行了灰色关联分析，揭示了不同阶段各因素对粮食单产影响程度的变化。
At the same time of trend monitoring , we strengthened output monitoring of the main rivers , sewages alongshore , oceanic functional zones and algae bloom inshore , made an integrative analysis and assessed the present quality state of fujian ' s ocean and finally compiled < report on the state of the marine environment in fujian , p . r . c in 2003 > 在开展趋势性监测的同时，加强了主要江河排污、近岸排污口、近岸海洋功能区和赤潮灾害的监测，综合分析和评价了海洋环境质量状况，编制了《 2003年福建省海洋环境质量公报》 ，现予以发布。
Firstly , those factors affecting on annual peak load are divided into two part including tendency and randomicity , based on which , the divided load model is improved . at the same time , this thesis present the nature random part of power load , in order to study the random part of power load more accurately 首先，本文将影响年最大负荷变化的因素分为趋势性与随机性两大类，从影响因素的角度改进年最大负荷的分解模型，细化随机分量的研究，提出年最大负荷的自然随机分量。
