儒学为学方法去“静”与“敬”的一致性

在《河北师范大学学报》2023年第4期撰文指出,在儒学“静”与“敬”作为为学的方式或方法,从根本上讲是一致的,没有实质性的区别。如果说,“敬”不仅在心理意识层面上“直内”或“主乎中”,也可以在行为模式层面上“执事敬”,则“静”也同样不仅在心理意识层面上“虚一而诚”,也可以在行为模式层面上“随物顺应”“感而遂通”。如果要说二者有区别,那么“静”主要在哲学体悟的意义上运用,而“敬”的意义则更宽泛一些。

朱熹是个“空谈义理”的理学家吗?──试论朱熹经世致用思想

谈《论语》的教学之道

《论语》作为一部内容丰富的儒家经典,它在教学领域有许多精髓的见解,其中既有对学习与道德修养相互作用的论断,又有对治学态度、为学方法和教育方式等方面的深刻阐述。这些教学之道不仅在当时有很强的指导意义,而且到现在仍然有其宝贵的借鉴价值。它没有因离我们时代久远而影响其生命力,而是随着历史的推进益发闪烁出智慧的光辉。

论李顒与颜元体用思想之差异

李与颜元基于各自对时代的认识提出了其实学主张。李强调明体适用，体用兼赅，却无法使体与用真正统一，仍表现出重体轻用的倾向；颜元强调实体实用，力图以用为基础来达到体用一致。与此相联系，二者所提出的为学方法也迥然有别。李以静坐与读书讲学作为其基本方法，而颜元则主张习动习行，事上历练，批判静坐与读书讲学的方法。李与颜元思想的这种差异。

Corrosion behavior of hafnium in anhydrous isopropanol and acetonitrile solutions containing bromide ions

The corrosion behaviors of hafnium in Et4NBr isopropanol and acetonitrile(ACN)solutions were investigated usingelectrochemical measurements,ICP-AES and SEM techniques.Results revealed that the open circuit potential gets more positive dueto the increased passivity of the surface oxide film with increasing immersion time until it reaches a steady state value.Thepotentiodynamic anodic polarization curves did not exhibit an active dissolution region near corrosion potential due to the presenceof an oxide film on the electrode surface,which was followed by pitting corrosion.SEM images confirmed the existence of pits onthe electrode surface.Cyclic voltammetry and galvanostatic measurements allowed the pitting potential(φpit)and the repassivationpotential(φp)to be determined.φpit increased with increasing potential scanning rate but decreased with increasing temperature,Br-concentration and ACN concentration.The impedance spectra showed that the resistances of the solution and charge transferdecreased with the increase of ACN concentration.

Colorectal cancer screening behavior and willingness

The outpatient-based study by Deng et al [World J Gastroenterol 2011 July 14; 17(26): 3133-3139] on the factors that may influence the colorectal cancer (CRC) screening feasibility, encouraged our curiosity. Establishing a simple method for quickly assessing the educational level of patients and modulating a questionnaire for each type of patient, may be an effective protocol to increase the people participation, mainly in countries where sufficient medical resources and financial support are lacking. In fact, the knowledge directly affects the feasibility when screening is offered. Patient educational level influences the understanding of the knowledge and the screening method. This factor may affect patient's priority level on the study participation, the understanding of questions, and the motivation to complete the questionnaire and, consequently, the screening success. Recent studies have found a relationship between high educational level and CRC screening participation, and emphasized the question-naire ineffectiveness in the illiterate people. Although the questionnaire is an excellent method for this kind of evaluation, physician's contribution could be the most important factor associated with the screening method. Thus, further studies should be conducted to explore the compliance of patients with low educational level and to look for the best solutions for their enrollment.

Evaluation of the propensity for coal spontaneous combustion based on catastrophe theory

Generally, different prevention measures should be taken according to spontaneous combustion propensities. The current methods to evaluate the propensity of coal spontaneous combustion, such as chromatographic method of oxygen adsorption, oxidation kinetics method and activation energy method, are mostly affected by human factors. Their boundaries among different classes of propensities were all established by subjective judgments. A new evaluation method using catastrophe theory is introduced. This method can accurately depict the process of coal spontaneous combustion and the evaluation index, ＂catastrophe temperature＂, be obtained based on the model. In terms of catastrophe temperature, the spontaneous combustion propensity of different coals can be sequenced. Experimental data indicate that this method is appropriate to describe the spontaneous combustion process and to evaluate the propensity of coal svontaneous combustion.

The Essence of Group Discussions

Group discussions are very important in oral English classes. It maximizes students＇ speaking time in a specified-time period. Group discussions have a strong positive effect on the atmosphere in the classroom and the behaviors of the students as they can get more ideas from their friends, and sometimes students don＇t even understand the topic for discussion but by interacting with others they can understand the topic. Particularly it is a good warm-up in conversational classes. The most important reason for using group discussions before speaking tasks is to reduce students＇ nervousness of making mistakes. And this encourages students to be more active in speaking class.

The Sociological Analysis on the Teacher＇ s Notion of Judging Students Based on Achievements

There is a popular notion of teachers that they judge a student according to their score. On this basis, teachers developed a systematical thinking method, perspective and way of act. Currently, teachers arrange seats and interact with students and do many other things according to their score sub-consciously. This phenomenon, however, has a long-standing basis on which the school evaluates teachers and teachers evaluate themselves.

＂I＇m here to discuss my final grade!＂ A study of the speech act of complaint by Malaysian ESL learners

The present study investigates the preferred strategies of the speech act of complaint by Malaysian ESL learners. The subjects were selected from Malaysian university students majoring in English at University Sains Malaysia. Data were collected through an open-ended questionnaire in the form of a discourse completion task and a semi-structured interview. The responses were analyzed based on Rinnert and Nogami＇s （2006） taxonomy of the speech act of complaint to examine the main components of complaint, the level of directness and the degree of mitigation. It is anticipated that the findings will be able to provide valuable insights into teaching and learning English in non-native settings.

Elastic Behavior of Polymer Chains

The elastic behavior of the polymer chain was investigated in a three-dimensional off-lattice model. We sample more than 109 conformations of each kind of polymer chain by using a Monte Carlo algorithm, then analyze them with the non-Gaussian theory of rubberlike elasticity, and end with a statistical study. Through observing the effect of the chain flexibility and the stretching ratio on the mean-square end-to-end distance, the average energy, the average Helmholtz free energy, the elastic force, the contribution of energy to the elastic force, and the entropy contribution to elastic force of the polymer chain, we find that a rigid polymer chain is much easier to stretch than a flexible polymer chain. Also, a rigid polymer chain will become difficult to stretch only at a quite high stretching ratio because of the effect of the entropy contribution. These results of our simulation calculation may explain some of the macroscopic phenomena of polymer and biomacromolecular elasticity.

Kinetic Behavior of Aggregation-Exchange Growth Process with Catalyzed-Birth

We propose an aggregation model of a two-species system to mimic the growth of cities＇ population and assets, in which irreversible coagulation reactions and exchange reactions occur between any two aggregates of the same species, and the monomer-birth reactions of one species occur by the catalysis Of the other species. In the case with population-catalyzed birth of assets, the rate kernel of an asset aggregate Bκ of size k grows to become an aggregate Bκ＋1 through a monomer-birth catalyzed by a population aggregate Aj of size j is J（κ,j） = Jkjλ. And in mutually catalyzed birth model, the birth rate kernels of population and assets are H（k,j）=Hkjη and J（k,j） = Jkjλ, respectively. The kinetics of the system is investigated based on the mean-field theory. In the model of population-catalyzed birth of aseets, the long-time asymptotic behavior of the assets aggregate size distribution obeys the conventional or modified scaling form. In mutually catalyzed birth system, the asymptotic behaviors of population and assets obey the conventional scaling form in the case of η=λ =0, and they obey the modified scaling form in the case of η=0, λ=1. In the case of η = λ= 1, the total mass of population aggregates and that of asset aggregates both grow much faster than those in population-catalyzed birth of assets model, and they approaches to infinite values in finite time.

Extended digital image correlation method for micro-region deformation measurement

Extended digital image correlation(X-DIC) method is one novel test method in experimental mechanics.In this paper,the principle of the X-DIC method was introduced in detail.A selection scheme of the initial value of Newton iteration method was proposed when Newton iteration method was applied to solve the partial differential equations.This scheme could make the X-DIC method suitable for the large deformation measurement and avoid the non-convergence phenomenon effectively.The performance of the X-DIC method was verified by simulated images.Since the pixel point with the maximum absolute error occurred mainly at the corner or on the interface of the region of interest(ROI,region used for correlation calculation),measured deformation of the core area(area surrounding the center point of the ROI with a smaller size) was taken as the reliable measured value.The measurement accuracy of the X-DIC method could be improved greatly by using the core area.Combined with a long-distance microscope,the X-DIC method could be used in the deformation measurement of the micro-region.Zero deformation experiment was done to test the precision of the measurement system.Then,the X-DIC method was applied to measure the micro-region deformation of the specimen with a crack.Test value was proved to be in accordance with the actual deformation,showing that the X-DIC method is suitable for the research of microscale mechanical behavior of materials.

CFD Study of Ejector Flow Behavior in a Blast Furnace Gas Galvanizing Plant

In recent years, there has been a growing interest toward Blast Furnace Gas （BFG） as a low-grade energy source for industrial furnaces. This paper considers the revamping of a galvanic plant furnace converted to BFG from natural gas. In the design of the new system, the ejector on the exhaust line is a critical component. This paper studies the flow behavior of the ejector using a Computational Fluid Dynamics （CFD） analysis. The CFD model is based on a 3D representation of the ejector, using air and exhaust gases as working fluids. This paper is divided in three parts. In the first part, the galvanic plant used as case study is presented and discussed, in the second part the CFD approach is outlined, and in the third part the CFD approach is validated using experimental data and the numerical results are presented and discussed. Different Reynolds-Averaged Navier-Stokes （RANS） turbulence models （k-to SST and k-e Realizable） are evaluated in terms of convergence capability and accuracy in predicting the pressure drop along the ejector. Suggestions for future optimization of the system are also provided.

Sodium dodecyl sulfate sensitized electrochemical method for subnanomole level determination of ortho-phenylphenol at a novel disposable electrode

The electrochemical behavior of ortho-phenylphenol （OPP） at a disposable electrode （an improved wax-impregnated graphite electrode） in the presence of sodium dodecyl sulfate （SDS） was studied for the first time. The results demonstrated that the electrocatalytic oxidation process of OPP was accompanied with two-charge-two-proton transference. The electronic transmission coefficient （a） and diffusion coefficient （DR） for OPP were calculated to be 0.8126 and 3.61× 10^-2 cm2/s, respectively. The electrochemical signal was apparently improved by SDS at the disposable electrode and the oxidative peaks current was proportional to the concentration of OPP over the range from 1.0 ×10^-9 to 4.0 × 10^-6 mol/L with the detection limit of 8.7× 10^-10 mol/L. This novel and highly sensitive method can be successfully applied to detect OPP in the orange rind sample.

GLOBAL ASYMPTOTIC STABILITY FOR A TWO-SPECIES DISCRETE RATIO-DEPENDENT PREDATOR-PREY SYSTEM

The dynamical behaviors of a two-species discrete ratio-dependent predator-prey sys- tem are considered. Some sufficient conditions for the local stability of the equilibria is obtained by using the linearization method. Further, we also obtain a new sufficient condition to ensure that the positive equilibrium is globally asymptotically stable by using an iteration scheme and the comparison principle of difference equations, which generalizes what paper [G. Chen, Z. Teng and Z. Hu, Analysis of stability for a discrete ratio-dependent predator-prey system, Indian J. Pure Appl. Math. 42（1） （2011） 1-26] has done. The method given in this paper is new and very resultful comparing with papers [H. F. Huo and W. T. Li, Existence and global stability of periodic solutions of a discrete predator--prey system with delays, Appl. Math. Comput. 153 （2004） 337-351; X. Liao, S. Zhou and Y. Chen, On permanence and global stability in a general Gilpin- Ayala competition predator prey discrete system, Appl. Math. Comput. 190 （2007） 500-509] and it can also be applied to study the global asymptotic stability for general multiple species discrete population systems. At the end of this paper, we present an open question.
