Optimum Design of Movable Screen Jig CycleChunbao Sun; Yubo Sun(1 Resources Engineering School, University of Science and Technology Beijing, Beijing 100083. China2 Department of Mineral Engineering, Northeastern University. Shenyang 10006. China)摘 要:Witht......
-DRIVE,and a self developed program were used to build up the vehicle model, and was applied to compute the fuel economy of the vehicle. The computation was conducted using a typical driving cycle to simulate a working cycle of the garbage pickup. The simulated fuel economy of the hydraulic hybrid vehicle and the engine operation points were compared to that of the original vehicle. The results......
High cycle fatigue behavior of the second generation single crystal superalloy DD6 SHI Zhen-xue, LI Jia-rong, LIU Shi-zhong, HAN Mei National Key Laboratory of Science and Technology... single crystal superalloy DD6 with 0.10%Hf and 0.34%Hf (in mass fraction) was subjected to high-cycle fatigue (HCF) loading at temperatures of 700 °C in ambient atmosphere. SEM was used to determine......
J. Cent. South Univ. (2019) 26: 3372-3387 DOI: https://doi.org/10.1007/s11771-019-4260-y Coupling effect of evaporation and condensation processes of organic Rankine cycle for geothermal power... and Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract: Organic Rankine cycle (ORC) is widely used for the low grade geothermal power generation. However, a large amount of irreversible......
Cycle stability of lithium/garnet/lithium cells with different intermediate layersNing Zhao1,Rui Fang2,3,Ming-Hui He2,3,Cheng Chen2,3,Yi-Qiu Li3,Zhi-Jie Bi1,Xiang-Xin Guo1,31. College of Physics... with the thickness of 100 nm were prepared. Although the interfacial resistance with the Au layer decreases from 1960 to 32 Ω·cm2, the cells can only cycle for 0.67 h at 0.5 mA·cm-2, related to the Au......

低碳经济与钢铁工业徐匡迪1(1.北京市工程院 )摘 要:气候变暖除自然原因(火山,太阳活动等)外,还受到工业革命250多年来,应用化石燃料大量排放温室气体的影响.钢铁工业以碳冶金为基础,生产过程的CO2排放(以下按国际惯例简称为碳排放)占全球总量的5%~6%.中国因处于工业化,城镇化的中期,钢铁产销量大,故钢铁工业的碳排放已达到全国总排放的15%左右.在2020年前各国钢铁工业的主要对策是长流程节能减排,与扩大电炉炼钢为核心的短流程.中国钢铁工业的燃料比与国际先进水平相比尚有15%~20%的差距,有较大减排......
Low cycle fatigue behavior of high strength gun steelsMaoqiu Wang;Han Dong;Qi Wang;Changgang Fan Division of Structural Materials, Central Iron & Steel Research Institute, Beijing 100081, China摘 要:<正> The low cycle fatigue (LCF) behavior of two high strength steels, with norminal chemical compositions (mass fraction, %)of 0.40C......
cycle length, a specific method for dividing the Hénon attractor into numerous non-overlapping sub-regions, and a new one-to-one mapping strategy between the divided sub-regions and elements of dynamically generated matrix consisting of 0’s and 1’s are proposed. Experimental results demonstrate that the generated key-streams are with long enough cycle length and very sensitive to the initial values......
