: acoustic emission; temperature change; location accuracy; structural cracks 1 Introduction In the early 1950s, Kaiser’s research marked the beginning of modern acoustic emission (AE) technology. AE... the structure causes the change of the wave velocity in the structure. (2) In the later period of heating, the internal expansion of the structure leads to structural cracking, and the location error of the pulse......
, and the analysis of the slope stability was given based on the strength reduction. The results show that the structural parameters and cohesion change with similar hyperbola, and internal friction angle...; 文献标志码:A 文章编号:1672-7207(2010)01-0328-07 Relationship between soil structural parameters and strength and its application in slope stability......
investigated by TEM. 4) During heat-treating the Ti-67B powder milled for 60 h, the structural change of TiB2, including grain growth and lattice ordering degree increase may occur. When the MAed powder...(TEM) were used to study the structural evolution of the powder during ball milling. The effects of heat treatment on the structural evolution and thermal stability of the mechanically alloyed(MAed......

; Abstract: The structural and electronic properties of bulk and (001) plane of TiC were investigated by the first-principles total-energy pseudopotential method based... one. The calculated results of structural relaxation and surface energy for TiC(001) slab indicate that slab with 7 layers shows bulk-like characteristic interiors, and the changes of slab occur......
implantation. In this study, 18 drug-eluting biodegradable AZ31 B stents were implanted into porcine coronary arteries to assess its structural integrity, corrosion behavior and microstructure change... the study. Inferred from this study, it is shown that the loss of AZ31 B stent structural integrity may be the result of stress concentration, degradation and microstructure change.关键词:......
Optimal design considering structural efficiency of compressed natural gas fuel storage vessels for automobiles Myung-Chang KANG1, Hyung Woo LEE1, Chul KIM2 1. National Core Research Center.... Therefore, the new proposed shape products give a mass reduction of 4.8 kg(5.1%) Key words: CNG fuel storage vessel; mechanical property; dome part; bursting; structural analysis 1 Introduction......
the classification model so as to adjust the concept change or the boundary change between the classes. Hence, we design a novel fuzzy classifier known as THRFuzzy to classify new incoming data streams...; tangential holoentropy; concept change 1 Introduction Data analysis using classifiers is an important task in applications like machine learning, pattern recognition, and data mining [1]. In the classical......

Masing Behavior and Microstructural Change of Quenched and Tempered High-Strength Steel Under Low Cycle FatigueFeng-Mei Bai1,2,Hong-Wei Zhou3,Xiang-Hua Liu1,Meng Song3,Ya-Xin Sun3,Hai-Long Yi1,Zhen... steel(Q960 E) was studied in the strain amplitude ranging from ± 0.5% to ± 1.2% at room temperature. As a result of fatigue loading, the dislocation structural evolution and fracture mechanism were......
