Abstract This paper points out that the Landau criterion for macroscopic superfluidity of He H is only a criterion for microscopic superfluidity of ^4He, extends the Landau criterion to microscopic superconductivity in fermions （electron and hole） system and system with Cooper pairs without long-range phase coherence. This paper gives another three non-superconductive systems that are of microscopic superconductivity. This paper demonstrates that one application of microscopic superconductivity is to establish room temperature electronics of the high-To cuprates.

Fractal Dimensions of Fractional Integral of Continuous functions

引用

Acta Mathematica Sinica,English Series 2016年第12期32卷 1494-1508页

作者： yong Shun LIANG Wei Yi su Institute of Science Nanjing University of Science and Technology Department of Mathematics Nanjing University

In this paper, we mainly explore fractal dimensions of fractional calculus of continuous functions defined on closed intervals. Riemann-Liouville integral of a continuous function f（x） of order v（v 〉 0） which is written as D-Vf（x） has been proved to still be continuous and bounded. furthermore, upper box dimension of D-v f（x） is no more than 2 and lower box dimension of D-v f（x） is no less than 1. If f（x） is a Lipshciz function, D-v f（x） also is a Lipshciz function. While f（x） is differentiable on [0, 1], D-v f（x） is differentiable on [0, 1] too. With definition of upper box dimension and further calculation, we get upper bound of upper box dimension of Riemann-Liouville fractional integral of any continuous functions including fractal functions. If a continuous function f（x） satisfying HSlder condition, upper box dimension of Riemann-Liouville fractional integral of f（x） seems no more than upper box dimension of f（x）. Appeal to auxiliary functions, we have proved an important conclusion that upper box dimension of Riemann-Liouville integral of a continuous function satisfying HSlder condition of order v（v 〉 0） is strictly less than 2 - v. Riemann-Liouville fractional derivative of certain continuous functions have been discussed elementary. Fractional dimensions of Weyl-Marchaud fractional derivative of certain continuous functions have been estimated.

引用

Acta Metallurgica Sinica(English Letters) 2022年第9期35卷 1407-1423页

Al–Co–Cr–Fe–Ni high entropy alloy(HEA) system is a newly developed category of metallic materials possessing unique microstructure, mechanical and functional properties, which presents many promising industrial applications. In recent years, additive manufacturing technology has given rise to a great potential for fabricating HEA parts of ultra-fine grains and geometrical complexity, thereby attracting great interest of researchers. Herein, a comprehensive review emphasizes on the recent developments in high-energy beam additive manufacturing of Al–Co–Cr–Fe–Ni HEA, in the aspects of their printing processes, microstructures, properties, defects, and post treatments. The technical characteristics of three typical high-energy beam additive manufacturing technologies for printing HEA, namely, selective laser melting(SLM), selective electron beam melting(SEBM), and directed energy deposition(DED) are systematically summarized. Typical crystal structure, grain, microstructure, as well as corresponding properties of Al–Co–Cr–Fe–Ni HEA manufactured by those technologies are primarily presented and discussed. It also elaborates the formation mechanisms of harmful defects related to the rapid solidification and complex thermal cycle during high-energy beam additive manufacturing. furthermore, several kinds of post treatments with an aim to improve performance of HEA are illustrated. Finally, future research directions for HEA by additive manufacturing are outlined to tackle current challenges and accelerate their applications in industrial fields.

Adsorption property of direct fast black onto acid-thermal modified sepiolite and optimization of adsorption conditions using Box-Behnken response surface methodology

引用

Frontiers of Environmental Science & Engineering 2013年第4期7卷 503-511页

作者： Chengyuan su Weiguang LI yong WANG School of Municipal and Environmental Engineering Harbin Institute of Technology Harbin 150090 China School of Environment and Resources Guangxi Normal University Guilin 541004 China National Engineering Research Center of Urban Water Resources Harbin 150090 China

The adsorption of direct fast black onto acid- thermal modified sepiolite was investigated. Batch adsorp- tion experiments were performed to evaluate the influences of experimental parameters such as initial dye concentra- tion, initial solution pH and adsorbent dosage on the adsorption process. The three-factor and three-level Box- Behnken response surface methodology （RSM） was utilized for modeling and optimization of the adsorption conditions for direct fast black onto the acid-thermal modified sepiolite. The raw sepiolite was converted to acid-thermal modified sepiolite, and changes in the fourier transform infrared spectrum （FTIR） adsorption bands of the sample were noted at 3435 cm] and 1427 cm1. The zeolitic water disappeared and the purity of sepiolite was improved by acid-thermal modification. The decoloriza- tion rate of direct fast black adsorbed increased from 68.2% to 98.9% on acid-thermal modified sepiolite as the initial solution pH decreased from 10 to 2. When the adsorbent dosage reached to 2.5 g. L-1, 2.0 g. L-~, 1.5 g. I,I and 1.0g.L-1, the decolorization rate was 90.3%, 86.7%, 61.0% and 29.8%, respectively. When initial dye concen- tration increased from 25 to 200 rag. L-l, the decolorization rate decreased from 91.9% to 60.0%. The RSM results showed that the interaction between adsorbent dosage and pH to be a significant factor. The optimum conditions were as follows： the adsorbent dosage 1.99 g.L-1, pH 4.22, and reaction time 5.2 h. Under these conditions, the decolor- ization rate was 95.1%. The three dimensional fluores- cence spectra of direct fast black before and after treatment showed that the direct fast black was almost all adsorbed by the acid-thermal modified sepiolite.
