Four kinds of P110 grade tube steels containing different chromium contents were designed to probe the in- fluence of Cr on the properties of tube steel. The microstrueture, mechanical properties and corrosion behavior of the four kinds of P110 grade tube steels were studied deeply and thoroughly. The analysis of the mechanical properties indicated that tensile strength and yield strength of the steel plates were improved, while transverse and longitudinal impact energy and elongation first increased and then decreased when Cr content rose. The impact energy and elonga tion reached the peak when Cr content was 1 ~. Cr precipitates were found only in 3 ~ Cr steel, with （Nb, Ti）（C, N） or Nb（C,N） as the core of precipitation and then grew up. The corrosion experiments demonstrated that the scales on the four steels had a two layer structure under the corrosion of CO2 and H2 S. The outer layer was mainly com- posed of FeS or FeS1 x and the inner layer consisted of FeCOa and Cr compounds. Cr was rich in the inner layer and the Cr content of the inner layer increased with the Cr content in matrix. The enriched Cr enhanced the compactness of the scales, further hindering the diffusion of ions from liquid to the surface of steel, thus reducing corrosion rate.

We study the entanglement between the internal(coin)and the external(position)degrees of freedom in the dynamic and the static deterministic aperiodic quantum walks(QWs).For the dynamic(static)aperiodic QWs,the coin depends on the time(position)and takes two coins C(α)and C(β)arranged in the two classes of generalized Fibonacci(GF)and the Thue–Morse(TM)*** found that for the dynamic QWs,the entanglement of three kinds of the aperiodic QWs are close to the maximal value,which are all much larger than that of the homogeneous ***,the first class of GF(1st GF)QWs can achieve the maximum entangled state,which is similar to that of the dynamic disordered *** the entanglement of 1st GF QWs is greater than that of the TM QWs,being followed closely by the entanglement of the second class of GF(2nd GF)*** the static QWs,the entanglement of three kinds of the aperiodic QWs are also close to the maximal value and 1st GF QWs can achieve the maximum entangled *** entanglement of the TM QWs is between1st GF QWs and 2nd GF ***,the entanglement of the static disordered QWs is less than that of three kinds of the aperiodic *** is different from those of the dynamic *** these results,we can conclude that the dynamic and static 1st GF QWs can also be considered as maximal entanglement generators.

A series of room-temperature ternary deep eutectic solvents （TDESs） were prepared from imidazolium halides, zinc halides and amides. The [BMIM]Cl-ZnCl2-acetamide （1：1：1） system shows the lowest freezing point （-60℃） and lowest density in the series. The viscosity and conductivity of TDESs have an exponential relationship with temperature and can be fitted by Arrhenius equation.

Dear editor,Massive multiple-input multiple-output (MIMO)is a key technology of the fifth generation wireless communication systems [1, 2]. Angle division multiple access (ADMA)[3] is one of the multiple access technologies to explore the spatial degrees of freedom. It is based on the channel characteristic of each user in the angle domain, thereby the dimension of channel matrix is reduced due to the sparse distribution of users [4].

Group key management technique is a fundamental building block for secure and reliable group communication *** order to successfully achieve this goal, group session key needs to be generated and distributed to all group members in a secure and authenticated *** most commonly used method is based on Lagrange interpolating polynomial over the prime field F p={0,1,2,…, p-1}. A novel approach to group key transfer protocol based on a category of algebraic-geometry code is presented over the infinite field GF(2 m). The attractive advantages are obvious. Especially, the non-repeatability, confidentiality, and authentication of group key transfer protocols are obtained easily. Besides, a more generalized and simple mathematical construction model is proposed which also can be applied perfectly to related fields of information security.

The effect of chemically reduced graphene oxide （CRGO） on the phase separation behavior of poly（methyl methacrylate）/poly（styrene-co-acrylonitrile）（PMMA/SAN） blends and the simultaneous response of rheological and conductive behavior of PMMA/SAN/CRGO nanocomposites upon annealing above the phase-separation temperatures were investigated. The introduction of CRGO causes the decrease of binodal temperature and the increase of spinodal temperature for PMMA/SAN blends and then enlarges their metastable regime. During annealing, the well-dispersed CRGO in the homogeneous blend matrix tends to be selectively located in the SAN-rich phase with the evolution of phase separation and then the CRGO further agglomerates effectively in the SAN-rich phase to form the conductive pathway. Thermal-induced dynamic percolation is observed for both the resistivity p and dynamic storage modulus G＇ as a function of annealing time. The resistivity variation is ascribed to the agglomeration of CRGO in the SAN-rich phase, while the modulus evolution is attributed to the combined contribution of phase separation for blend matrix and the agglomeration of CRGO in the SAN-rich phase.
