谈一篇论文意义上理论研究的逻辑之“真”——兼及“论证”与“议论”的分析

“真”乃哲学谓之“真”,即“真理”,亦可理解为理论研究如何才能“向真”并“走向真理”。“理论研究”指理性科学范畴内,针对人文社会科学领域问题的基于词语的以科学演绎(广义)为形式的思辨。尽管人文社会科学有其复杂性,但在向“真”的意义上与自然科学有本质一致性;“真”的理论研究必须以“真”的科学演绎(广义)作保证;建议将科学演绎(广义)之基本逻辑类、拓展逻辑类和综合逻辑类纳入视野,用以支持向“真”的逻辑展开;以提高研究质量为目的,研究者应该尽量多“论证”而少“议论”。讨论人文社会科学领域内一篇论文意义上的理论研究如何为“真”,就是要坚持向真的科学逻辑规则并执着前行,保证科学精神的实现。新概念不等于新思想,贩卖不是研究,赶时髦并非前沿,追捧虚假的学术风格就会丧失思考能力。因此,理论研究应以求“真”为使命,严守科学演绎的本质,严守责任重地,以自己所成立之思想突破呼应整个学科前沿的成功。

Simulation and Design of Fuzzy Sliding-mode Controller for Ship Heading-tracking

In considering the characteristic of a rudder,the maneuvers of a ship were described by an unmatched uncertain nonlinear mathematic model with unknown virtual control coefficient and parameter uncertainties.In order to solve the uncertainties in the ship heading control,specifically the controller singular and paramount re-estimation problem,a new multiple sliding-mode adaptive fuzzy control algorithm was proposed by combining Nussbaum gain technology,the approximation property of fuzzy logic systems,and a multiple sliding-mode control algorithm.Based on the Lyapunov function,it was proven in theory that the controller made all signals in the nonlinear system of unmatched uncertain ship motion uniformly bounded,with tracking errors converging to zero.Simulation results show that the demonstrated controller design can track a desired course fast and accurately.It also exhibits strong robustness peculiarity in relation to system uncertainties and disturbances.

Simulation Analysis of Macroeconomic Policy Orientations' Effects on the Industrial Economy——Based on Dynamic CGE Model

There are three different orientations of the macroeconomic policies,namely,factor-expansion,prudent-continuation and structural-adjustment.The paper uses the dynamic CGE model to simulate the effects of the three different orientations on the economy,and arrives at the following conclusions:while the factor-expansion policies can lead to growth of economic output,they also result in the further imbalance in the industrial structure and the "crowding-out effect" on the private investment.In addition,such growth is unsustainable in the long run;the growth of the industrial economy will decline rapidly to a lower level after reaching a certain high level.The prudent-continuation policies refer to the continuation of the current policies that sustain the current trends of the industrial economy,and such policies reduce the growth of the industrial economy to a lower level in the long run.The structural-adjustment policies reduce the economic output at the current stage;however,it can bring a gradual improvement of industrial structure and a balance of the supply and demand.In the long run,the optimized structure will improve the total factor productivity(TFP) and the production-possibility frontier,and thereby realize a longterm steady and rapid growth of the industrial economy.Four policy recommendations are proposed based on the simulation of the models,including taking the structural adjustment as the fundamental orientation of macroeconomic policies,lowering the "floor level" of economic growth with macro regulation,giving play to the fundamental role of market mechanism in structural adjustment and increasing the role of TFP in the growth of the industrial economy.

Anisotropic Bianchi Type-I Magnetized String Cosmological Models with Decaying Vacuum Energy Density A(t)

The present study deals with a spatially homogeneous and anisotropic Bianehi-I cosmological models representing massive strings with magnetic field and decaying vacuum energy density A. The energy-momentum tensor, as formulated by Letelier （1983）, has been used to construct massive string cosmological models for which we assume the expansion scalar in the models is proportional to one of the components of shear tensor. The Einstein＇s field equations have been solved by applying a variation law for generalized Hubble＇s parameter in Bianchi-I space-time. The variation law for Hubble＇s parameter generates two types of solutions for the average scale factor, one is of power-law type and other is of the exponential form. Using these two forms, Einstein＇s field equations are solved separately that correspond to expanding singular and non-singular models of the universe respectively. We have made a comparative study of accelerating and decelerating models in the presence of string scenario. The study reveals that massive strings dominate in the decelerating universe whereas strings dominate in the accelerating universe. The strings eventually disappear from the universe for sufficiently large times, which is in agreement with current astronomical observations. The cosmological constant A is found to be a positive decreasing function of time which is corroborated by results from recent supernovae Ia observations. The physical and geometric properties of the models have been also discussed in detail.

Yaw stability control using the fuzzy PID controller for active front steering

In order to improve the yaw stability of the vehicle with active front steering system, an adaptive PID-type fuzzy control scheme is designed to make the yaw rate tracking the desired values as close as possible. A 2-DOF vehicle model with active front steering is built firstly, and then the fuzzy PID controller is designed in detail. The simulation investigations of the yaw stability with different steering ma- neuvers are performed. The simulation results show the effectiveness of the fuzzy PID controller for improving the vehicle＇s yaw stability.

Numerical model of soft ground improvement by vertical drain combined with vacuum preloading

The rapid development of high-speed transportation infrastructure such as highway and high-speed railway has resulted in the advancement of soft soil improvement techniques. Vacuum preloading combined with vertical drains has been proved to be an effective method in the treatment of soft foundation. A three-dimensional numerical analysis of the coupled methods was presented, in which the smear zone and the well resistance were taken into account. The variations of the basic soil parameters including the permeability coefficient and the coefficient of volume compressibility were considered in the numerical model. The result of the numerical model was then compared to the measured value. The results indicate that the decrease of coefficient of volume compressibility accelerates the consolidation of the soil while the influence of hydraulic conductivity is insignificant. A cube drain presents the closest result to the real situation compared to the other equivalent methods of prefabricated vertical drain (PVD). The case study indicates that the numerical model with variation of soil parameters is closer to the measured value than the numerical model without variation of soil parameters.

A new approach to test generation for combinational circuits

Aimed at the generation of high-quality test set in the shortest possible time, the test generation for combinational circuits （CC） based on the chaotic particle swarm optimization （CPSO） algorithm is presented according to the analysis of existent problems of CC test generation, and an appropriate CPSO algorithm model has been constructed. With the help of fault simulator, the test set of ISCAS＇ 85 benchmark CC is generated using the CPSO, and some techniques are introduced such as half-random generation, and simulation of undetected fauhs.with original test vector, and inverse test vector. Experimental results show that this algorithm can generate the same fault coverage and small-size test set in short time compared with other known similar methods, which proves that the proposed method is applicable and effective.

Vacuum Ultraviolet Photodissociation Dynamics of N_(2)O+hν→N_(2)(X^(1)Σg+)+O(^(1)S0) in the Short Wavelength Tail of D^(1)Σ+Band

Vacuum ultraviolet photodissociation dynamics of N2O+hν→N2(X^(1)Σg+)+O(^(1)S0)in the short wavelength tail of D^(1)Σ+band has been investigated using the time-sliced velocity-mapped ion imaging technique by probing the images of the O(^(1)S0)photoproducts at a set of photolysis wavelengths including 121.47 nm,122.17 nm,123.25 nm and 123.95 nm.The product total kinetic energy release distributions,vibrational state distributions of the N2(X^(1)Σg+)photofragments and angular anisotropy parameters have been obtained by analyzing the raw O(^(1)S0)images.It is noted that additional vibrationally excited photoproducts(3≤v≤8)with a Boltzmann-like feature start to appear except the non-statistical component as the photolysis wavelength decreases to 123.25 nm,and the corresponding populations become more pronounced with decreasing of the photolysis wavelength.Furthermore,the vibrational state specific anisotropy parameterβat each photolysis wavelength exhibits a drastic fluctuation nearβ=1.75 at v<8,and decreases to a minimum as the vibrational quantum number further increases.While the overall anisotropy parameterβfor the N2(X^(1)Σg+)+O(^(1)S0)channel presents a roughly monotonical increase from 1.63 at 121.47 nm to 1.95 at 123.95 nm.The experimental observations suggest that there is at least one fast nonadiabatic pathway from initially prepared D^(1)Σ+state to the dissociative state with bent geometry dominating to generate the additional vibrational structures at high photoexcitation energies.

Simulation Study on SAR Images of the Oceanic Internal Waves

Based on the research of Lynett and Liu, the horizontal fully two-dimensional, depth-integrated model for the internal wave propagation is re-deduced. By combining this model with the M4S model, the propagation process of the internal waves is simulated in Synthetic Aperture Radar （SAR） images. The simulation results clearly show the bottom effects during the propagation such as fission and isobaths-parallelized propagation direction. This simulation procedure can lay the foundation for the quantitative interpretation of internal waves from fully two-dimensional SAR images.

China＇s Household Consumption Decline Amidst Rising Income Inequality： A Theoretical and Empirical Study

This paper studies the relationship between the widening urban-rural income inequality and weak household consumption demand in China. The theoretic model shows that households with higher income have lower average and marginal propensity to consume （APC and MPC）, and that the larger the income gap is, the weaker household consumption demand becomes. This paper tests the theoretical model with the panel data of 28 Chinese provinces, municipalities and autonomous regions from 1978 to 2009. The results show that with an increase of RMBIO, O00 in income, household APC drops by 25.6 percent and MPC by 7.0 percent,＂ and that if the income gap widens by one unit, household consumption rate drops by 6. 5 percentage points. Simulation results reveal that the widening urban-rural income inequality caused an extra drop of 3.42 percentage points in household consumption rate from 2000 to 2008, which accounts for 30.8 percent of the total drop in household consumption rate during that period.
