This paper presents two conceptual models of displacement transfer, reverse sym- metry model and infinitely equal division model, based on the fault-bend folding theory. If the fault shape is held constant in the trend, then the distribution of slip magnitude, geometry of imbricate structures and its axial surface map all display reverse symmetry on the process of displacement transfer, as called reverse symmetry model in this paper. However, if the ramp height of thrust fault decreases gradually along its strike, the displacement is postulated to be equally and infinitely divided to every thrust that is formed subsequently, this kinematic process is described using infinitely equal division model. In both models, displacement transfer is characterized by the regular changes of imbricate thrusting in the trend. Geometric analysis indicates that the displacement transfer grads can be estimated using the tangent of deflective angle of hinterland structures. Displacement transfer is often responsible for the distortion and branching of the surface anticlines, especially in the region where the multi-level detachment structures is developed. We also present some examples from the frontal structures of the Southern Tianshan fold-and-thrust belt, Xinjiang, China. Displacement transfer between deep imbricate thrusts in the middle segment of Qiulitag anticline zone causes the Kuqatawu and Southern Qiulitag deep an- ticlines left-lateral echelon. The region, where these two deep anticlines overlap, is characterized by duplex structures, and extends about 18 km. The shallow anticline is migrated southward displaying obvious “S” form in this area.

To improve the tensile bond strength of denim bonding agents, the adhesion between denim and MMA resin was investigated by applying initiator systems containing 1-cyclohexyl-5-ethyl barbituric acid (CEB), copper acetyl acetonate (CAA), quaternary ammonium chloride (QAC). cupric ion, with the addition of TEGDMA, an.d pretreatment solution for denim, and an HEMA primer. The effects of a cross-linking agent on barbituric acid-initiated denim bonding resin were examined by measuring degree of conversion, molecular weight, hardness of bonding resin, and tensile bond strengths.

Abstract: On the basis of the capture potential of force field and the adiabatic invariance proposed by Bates, the quadratic force constants between divalent metal ions in Ⅱ B group and ligands were calculated. Compared with the experimental results, the calculated contants are satisfactory and the reasons for the difference are given.

Ferromagnetic barrier-induced negative differential conductance on the surface of a topological insulator

引用

Chinese Physics B 2014年第10期23卷 464-468页

作者：安兴涛 School of Sciences Hebei University of Science and Technology department of Physics and Center of Theoretical and Computational Physics University of Hong Kong

The effect of the negative differential conductance of a ferromagnetic barrier on the surface of a topological insulat（ is theoretically investigated. Due to the changes of the shape and position of the Fermi surfaces in the ferromagnetic barrie the transport processes can be divided into three kinds： the total, partial, and blockade transmission mechanisms. The bias voltage can give rise to the transition of the transport processes from partial to blockade transmission mechanisms, which results in a considerable effect of negative differential conductance. With appropriate structural parameters, the currenl voltage characteristics show that the minimum value of the current can reach to zero in a wide range of the bias voltag and then a large peak-to-valley current ratio can be obtained.

引用

Chinese Science Bulletin 1988年第20期33卷 1740-1741页

作者：施恩伟 department of mathematics Yunnan Normal University Kunming

In this letter, we shall prove that the hypothesis is correct, i. e. the number of lower solutions of a fuzzy relation equation on a finite set is not more than 2~n—1, which was proposed by E. Czogala, J. Drewniak, W. Pedeycz in 1982 (see Fuzzy Sete and Systems, 7(1982),89—101). We shall also introduce a precise estimation on the number of lower solutions.
