These experiments are described  and 3 TSI composites constructed by the datasets of these experiments are introduced. The differences of the original data  composite approach and trend of the 3 TSI composites are shown. The argument of the different trends of the 3 TSI composites is discussed  and a conclusion is gotten that low accuracy  low quality and the relative shortage of the early TSI measurement data are the substantial reasons of the differences among the 3 TSI composites. 2012 TSI Press.   Alternating stress dynamics analysis of harmonic gear flexible wheel (EI CONFERENCE) 会议论文  OAI收割 2012 International Conference on Electrical Insulating Materials and Electrical Engineering, EIMEE 2012, May 25, 2012 - May 27, 2012, Shenyang, Liaoning, China 作者:  Li M. 收藏  |  浏览/下载：22/0  |  提交时间：2013/03/25 This article is the study of alternating stress of flexible wheel in harmonic gear drive system. Firstly  then  Finally  according to elasticity theory to theoretically analyze flexible wheel stress  based on the basic principle of sub-structure modal synthesis method  based on the dynamics simulation  use the software of UG  to analyze the alternating stress simulation results of flexible wheel and compare theoretical results and simulation results to come conclusion. The results show that: altering stress simulation results of flexible wheel are coincident with theoretical simulation results  PATRAN and ADAMS to carry out co-simulation  have a deeper understand the stress change trend in the drive process of flexible wheel  lay a foundation for further carrying out dynamics simulation of harmonic gear drive system.

First  establish an appropriate extrapolation model based on the existing data series  and then fit correlation functions other than existing data by derivative least squares method  finally perform spectrum analysis using extrapolated correlation functions. Numerical simulations and the experimental results show that good results are achieved no matter correlation functions change slow or rapid  and the extrapolation error is not more than 2.3%. 2012 Springer-Verlag Berlin Heidelberg.   REGIONAL TREND ANALSIS OF THE AEROSOL OPTICAL DEPTH COMPARING TO MODIS AND MISR AEROSOL PRODUCTS 会议论文  OAI收割 2012 Ieee International Geoscience and Remote Sensing Symposium, New York Guo, Jing; Gu, Xingfa; Cheng, Tianhai; Xie, Donghai; Chen, Hao 收藏  |  浏览/下载：13/0  |  提交时间：2014/12/07 MODIS  MISR  AOD  trend  linear regression
