So our new method uses the wavelets to decompose sttf data to different scale ( frequency ) spaces and predicts each scale space separately . for the sake of better prediction of large - scale data , we suggest to use the wavelets that have better smooth property 鉴于此，我们提出用小波( wavelet )将短时交通流数据分解到不同尺度(频率)空间，再在各尺度空间分别进行预测，将预测的结构综合得到原流量序列的预测值的方法。
First , the repeated structural analyses for static and dynamic characteristics are needed in the integrated optimization of composite wing structures . in this situation , the finite element model ( fem ) is time - consuming , while the continuum equivalent plate model ( epm ) is more efficient and often used 首先，复合材料翼面结构综合优化设计需要反复进行结构静力和动力特性分析，如果采用有限元模型( finiteelementmodel ，简称fem ) ，则其工作量太大。
Microstructure of in - situ toughened si3n4 ^ can be characterized with the first principle component of the original eight characterization variables , namely , a complex microstructure index . this index reflects the comprehensive microstructure characteristics and the contrasts between the micro structure ' s comprehensive status and its variance 自增韧si _ 3n _ 4陶瓷的显微结构可以用第一个主成分? ?综合结构指标来表征，它反映了显微结构的综合特征，并反映了显微结构综合表征值与显微结构偏差之间的对比。
( 5 ) from the point of the pavement function request and the whole evaluation system , define the pavement quality index ( pqi ) which represents the holistic pavement structure performance , establish the evaluation model and rating standard , apply the fuzzy theory , the theory of set pair analysis and the gray system theory in the evaluation of pavement performance , and create some appraisal models ( 5 )从路面的功能需求和评价系统的整体出发，对路面结构综合使用性能指数pqi进行了定义，并建立了相应的评价计算体系和分级标准，探讨了模糊数学理论、集对论和灰色系统理论等在路面结构使用性能评价中的应用，建立了多个评价分析模型。
Combined with modem structural finite element analysis , modern structural optimization algorithms , composite structures mechanics and aeroelastic tailoring of composite wing as well as relative high performance numerical method , a system named the composite synthesis optimization for aircraft structures ( cosoas ) , has been developed in this paper , which has own independent component of finite element analysis 本文结合现代结构有限元分析方法、现代结构优化算法、复合材料结构力学、复合材料气动弹性剪裁设计方法以及相关的高性能数值计算工具开发出了拥有自己独立有限元程序的复合材料飞机结构综合优化设计系统( cosoas ) 。在内容上本文突出复合材料应用特色。
This thesis expatiates on the reasons for the alteration of industrial location of shenyang and combines static and qualitative analysis with dynamic and quantitative analysis respectively to explain the altering process of industrial structure in shenyang , then validates the opinion of region economic geography that department structure is the main substance content of economic region while spatial structure is the representative form of economic region through compare and analysis by combining the industrial region with the industrial structure in shenyang 以工业区位论为主要理论依据，按时序借鉴不同阶段的工业区位论，如古典工业区位论与现代工业区位论，阐述沈阳工业区位变迁的原因；采用产业结构分析的多种方法，静态与动态、定性分析与定量分析相结合，说明沈阳工业结构变化的过程。然后，把沈阳工业区位与工业结构综合起来，进行比较分析，验证区域经济地理学的观点? ?部门结构是经济地域的主要物质内容，空间结构是其经济地域表现形式。
