Boolean functions with a variety of secure cipher properties are the key factors to design cryptosystem with the ability to resist multiple cipher attacks and good safety performance. In this paper, using the derivative of the Boolean functions and the e-derivative defined by ourselves as the main research tools, we study algebraic immunity, correlation immunity and other cryptographic properties of the quadratic rotation symmetric Boolean functions. We determine the quadratic rotation symmetric Boolean functions which are H Boolean functions, and the range of weight distribution of the quadratic rotation symmetry H Boolean functions. Besides, we get the compatibility among propagation, balance, correlation immunity and algebraic immunity of the quadratic rotation symmetry H Boolean functions, and also focus on the relationship of balance, correlation immunity and dimension. Furthermore, we check the existence of the cubic rotation symmetry H Boolean functions, and obtain the relationship between existence and dimension of the cubic rotation symmetry H Boolean functions. Moreover, we obtain a more convenient method for solving annihilator. Such researches are important in cryptographic primitive designs, and have significance and role in the theory and application range of cryptosystems.

This work presents a numerical study on airflow and particle dispersion within an urban street canyon with different wedge-shaped roof. A two-dimensional computational fluid dynamics (CFD) model for evaluating the airflow and particles dispersion within a street canyon was built up, which was based on the incompressible Reynolds Averaged Navier-Stokes equations, turbulence model and the particles transportation equation. It is revealed that: (1) particles dispersion inside an urban street canyon is mostly dominated by the in-canyon wind flow; (2) different wedge-shaped roof configurations causes a variety of particles distribution patterns; (3) air pollution levels are much higher in the step-down canyons relative to the step-up canyons; (4) the simulated result of FLUENT is reasonable, and the prospect of applying FLUENT to study atmospheric environment is very well. Key words: CFD; street canyon; particle dispersion; numerical simulation

In the existing wheel model, rim and rigid ring are connected with six direction spring and damper, which represent the elasticity of wheel carcass. In this paper, based on the ASCL original wheel model, the six direction hysteresis characteristic model of wheel carcass is built. In the vertical direction, Berg model which is widely used to describe the hysteresis characteristics of the rubber bushing is built to describe the hysteresis of wheel carcass, whose dynamic parameters are more consistent with the actual situation. In the other direction, the Fancher formula is used to describe the relationship of the force and displacement. Results showed out that the model has a high accuracy and is able to accurately describe hysteresis characteristics of wheel carcass by comparison with the suspension system K&C experimental results.

Suspension model can be divided into vertical hysteresis characteristic model and suspension guide-mechanism model according to its function. The relationship of the force and displacement is described in the existing vertical characteristic model, which does not consider the impact of the frequency. In the existing guide-mechanism model, the centerline of suspension K&C experimental data is used as the basis of the spindle position and attitude correction, without considering the hysteresis area. The problems above will affect simulation accuracy of vehicle dynamic. In this paper, hysteresis characteristic model of suspension is built. The vertical hysteresis model consists of spring, Maxwell element and Dehl friction unit. While in guide-mechanism model, if the hysteresis region is not obvious, considering the asymmetry, upper and lower borderlines are used to instead the centerline, and if the hysteresis characteristic is obvious, the Fancher formula is used to describe hysteresis range. Results showed out that the model has a high accuracy and is able to accurately describe hysteresis characteristics of suspension by comparison with the suspension system K&C experimental results.

Six modules (Y1~Y6) containing Y-type s-triazine based derivatives were optimized using density functional theory at B3LYP/6-31+G* level. On the basis of the optimized structure, electronic absorption spectrum was calculated with TD-DFT(TDB3LYP/6-31+G*) and the second-order nonlinear optical properties (NLO) were calculated with finite field (FF) method and coded programs. The results indicated that these molecules had good nonlinear optical properties with 106 order of magnitude a.u. (10-27 esu) of 0 value. Introducing different electron groups to the end of the tri-branched chain of this derivative would cause different results. Introduction of strong electron donating group would make a relatively large increase of u thus improving their second-order nonlinear optical properties, and making this derivative a good non-linear optical material.

In this paper, the peeling strength between ultra-thin copper foil and carrier is improved by some rare earths used as additives during the formation of the stripping layer of H-G alloy. The effect of different rare earth and their different contents on the stripping property of ultra-thin copper foil with carrier when they are added in the H-G plating solution is investigated, and the influence of rare earth on the cathodic polarization curves and cyclic voltammetry curves of H-G alloy during its electrodeposition is analyzed too. Results show that rare earth elements of La, Sm, Y and Ce increase the peeling strength between ultra-thin copper foil and carrier to a certain extent and the peeling strength is increased from 0.13 kgf •cm-1 to the range of 0.16 ~ 0.20 kgf •cm-1. Different rare earth contents also have impact on the peel strength and surface property of ultra-thin copper foil with a carrier support, in which the optimum adding amount of La is 0.1 g •L-1. Electrochemical test results show that the addition of rare earths can reduce the degree of the plating solution’s polarization, accelerate the electrode reaction speed, increase the alloy reduction capacity, promote alloy’s co-deposition, and improve the bonding strength between alloy layer and substrate, thus the peeling strength between ultra-thin copper foil and carrier is enhanced.

Based on the Turner’s liquid-loading model for gas wells, combined with Liquid Membrane Breaking Theory and Law of energy Conservation, a new liquid-loading model for mist flow in wave shaped crushing mode for gas-liquid wells was put forward, and a new equation for critical liquid-loading gas flow rate estimation was derived. The results show that the lowest conditions for liquid loading is that most of liquid drops can continuously move upward in gas flow, and when radii of liquid drops are smaller than 1600μm, liquid drops in the wellbore are basically in spherical shape. The critical liquid-carrying gas flow rate, in gas wells, calculated with this new model, is more reasonable and accurate.

Adsorption behavior of Rhodamine B (RhB) onto thermal modified rectorite (TM-R) has been thermodynamically investigated. The thermal modified rectorite prepared at different temperatures was characterized by X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET).

In the horizontal tee two branches pipe, pneumatic conveying experiment of hollow glass beading and millet was carried out using compressed air. The average diameters were both 2mm. The paper studied their resistance properties comparatively. The results showed: if the convey pressure was basically unchanged, for two kinds of particle which had the same average particle diameter but the different densities, when the openings difference value of the flow valve in the two branch pipes increased, in the region of higher gas velocity, the distance of the resistance properties curves became farther away, in the region of lower, curves were closer, the critical speed of branch pipe which had larger local resistance increased significantly, that of the other branch pipe declined slightly. The pressure drop value of particle with smaller density was smaller, the critical speed was generally higher, and the inflection point of the resistance characteristics curve appeared earlier.
