Therefore, it is a pivotal issue to determine the reserved thickness of rock plug during the construction of tunnels. The limit analysis principle is employed to analyze the safe thickness......
RCT-β Thickness Gauge Has Been DevelopedH.X.F.摘 要:<正> The RCT-β thickness gauge is a non-contact type instrument used for measuringthickness,which... degree of the attenuation in the intensity of the β-ray corresponds to the thick-ness of the material.The β-ray thickness gauge basing on this principle has been developed,whichis used to measure......
Electrical and optical modulation on ferroelectric properties of P(VDF-TrFE) thin film capacitorsXiaohan Li1,2,Biaohong Huang3,2,Weijin Hu3,2,Zhidong Zhang3,21. Shenyang National Laboratory... compared with metal Au electrode, we report on the modulation of ferroelectric properties of P(VDF-Tr FE) thin film capacitors both by electric field and UV light. A ferroelectric hysteresis loop shift......
Selective harmonic elimination method for wide range of modulation indexes in multilevel inverters using ICAAli Ajami, Mohammad Reza Jannati Oskuee, Ataollah Mokhberdoran, Hossein Shokri(Electrical... problem is solved by imperialist competitive algorithm (ICA). The conventional SHE methods cannot eliminate the selected harmonics and satisfy the fundamental component in some ranges of modulation......
Finite element analysis on stresses field of normalized layer thickness within ceramic coating on aluminized steel WU Zhen-qiang(吴振强), XIA Yuan(夏 原), LI Guang(李 光), XU Fang-tao(徐方涛) Institute... dipping aluminum(HDA) and plasma electrolytic oxidation(PEO). A triangle of normalized layer thickness was created for describing thickness ratios of HDA/PEO coatings. Then, the effect of thickness......
were prepared by wet ball milling method, their magnetoelectric (ME) effect was studied as a function of their constituents and modulation frequency. The results show that the ME coefficient increases as a function of modulation frequency from 400 to 1000 Hz and the ME characteristics of ME curves are also modified because the electrical conductivity of the CoFe2O4 phase is sensitive......
