原料和浸出渣的XPS谱图. 2 结果与讨论 2.1 浸出率及ICP-AES分析 锌置换渣的化学成分如表1所列,主要含Zn,Fe,Cu,Al,Pb,以及少量的Ga,Ge,Sn,Sb,As等元素.加压浸出(温度160 ℃,时间1.5 h,氧压0.75 MPa,搅拌速率600 r/min)及常压浸出(温度90 ℃,时间1.5 h,搅拌速率600 r/min)时不同硫酸浓度对Fe... rate of Fe element and filtration speed of leaching slurry 2.2 XRD分析 如图2所示,XRD谱表明锌置换渣的物相成分复杂,主要有铁酸锌(ZnFe2O4),硅铁铜铅石(Cu2Pb2(Fe, Al)2Si5O17·6H2O)[26],钙硅铅锌矿((Ca, Pb)ZnSiO4)及少量的铅钒(PbSO4).其中,Cu可能取代Zn以......
function models of the inverter under normal and fault state, a fast fault diagnosis method without sensors is proposed [12]. ALAVI et al [13] proposes a model-based diagnosis method for multi-level... and the corresponding reference bridge-arm status. Therefore, the implementation requires the measurement of every bridge-arm status. This method has a wide range of applications but requires additional sensors. WU et al......
. Concrete- filled steel tube (CFST) is a common form of CC. In recent years, some researchers have studied the mechanical properties of CC and its application in underground engineering. KWON et al [17] proposed axial compressive flexural strength and simplified interaction curves for a circular cross-section CC. With the curves, the member axial and flexural strength can be calculated. PORTOLS et al [18......
, N-butanol has been considered a prospective alternative fuel. WALLNER et al [10] studied the combustion and emission behaviors on a DI SI engine using 10% ethanol and 10% butanol addition... unregulated emissions. YANG et al [23] conducted engine dyno tests with a gasoline engine by using blends of gasoline and butanol, ranging from 10% to 35%. Their conclusions showed that when......
was developed by SASTRE et al [25]. Based on this model, equations in which a relationship was found between the permeability coefficient and equilibrium parameters as well as the concentrations of reagents were described. Furthermore, parameters such as diffusion resistances were calculated by means of the aforementioned model. Similarly, KAMRAN HAGHIGHI et al [27] developed a mass transfer model......
signal processing and mechanical fault diagnosis. Entropy has become one of the new ways of non-linear time series analysis. The AE method was first introduced by PINCUS et al [8] and YAN et al [9] who... to overcome this shortcoming, WU et al [20] presented a model called refined composite multiscale sample entropy (RCMSE). The main purpose of RCMSE is to promote the precision of entropy estimation......
accidents, improving driving safety and alleviating traffic congestion. The study of driving behavior models can be traced back to the driving-field-analysis proposed by GIBSN et al in the 1930s [11, 12... the study to a new height. Nevertheless, the research focuses on the differences and personalization of driving behavior, and to some extent ignores some commonalities in driving behavior. WANG et al......
behavior of salt rock had been investigated intensively by many researchers. Numerous creep models have been developed. YANG et al [8] quantitatively analyzed the effects of the confining and axial... was proposed by WANG [9] based on the introduction of a damage accelerating limit into a Carter’s creep model, which can simulate the damage process of the complete three-stage creep of salt rock. HOU et al......
. Massive researchers have explored different methods to preheat natural gas. HOWARD et al [11] proposed adopting fuel cells to preheat the upstream natural gas and improve electricity output at the same time. KOSTOWSKI et al [12] integrated an internal combustion engine (ICE) and an ORC system into the PRS. The jacket water and the exhaust gas of ICE are used to preheat natural gas; meanwhile......
