1TOLERANCE ANALYSIS OF A PLANETARY GEAR REDUCER UNDER CAD CIRCUMSTANCE显示文摘Tolerance analysis of a planetary reducer is conducted. By focusing the serially-arrangedparts in the central line and setting an appropriate dimension as a 'gap', worst-case tolerance analysismethod and statistical (RSS) tolerance analysis are used, and then a tolerance-analyzing tool CE/TOLis introduced. The acceptable value range of the 'gap' is from 1.5 mm to 3.5 mm. While worst-caseanalysis rejects the design, RSS accepts it by a more realistic result with the law of probability accounted.With the help of CE/TOL and CAD software Pro/E, all components’ dimensions and tolerances areassigned and modified, and more detailed and more comprehensible results are gives out.Zhu Fumin Li Wanli Maropoulos P G 2005Chinese Journal of Mechanical Engineering2005,18,3:11
2Synthesis of substituted benzoxazoles by the iron(Ⅲ)-catalyzed aerobic oxidation process显示文摘The FeCl3-catalyzed aerobic oxidation process for the synthesis of benzoxazoles,benzothiazole and benzimidazole has been discovered.This method has proved to be effective to a wide range of substrates,and it has been applied for the synthesis of JTP-426467.CAO Ke,TU YongQiang & ZHANG FuMin P State Key Laboratory of Applied Organic Chemistry and Department of Chemistry,Lanzhou University,Lanzhou 730000,China 2010Science China Chemistry2010,53,1:3
3Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment.Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei 2020National Science Review2020,7,1:2
