It is an important way to start the reform and development of teaching methods from the way of thinking. “The Trinity” as a way of thinking mode that embodies the two philosophical propositions of “one divides into three” and “engineering thinking” that can promote the teaching mode from three aspects: constructing new teaching model, improving teaching research strategy and starting the “teaching practice community”.  相似文献

Partial condensation of refrigerant R-11 was experimentally and theoretically studied. The test apparatus consisted of two concentric tubes, with the vapor flowing downward in the inner tube and the cooling water in the annular space in countercurrent direction. By using the available dimensionless correlation, the mean heat transfer coefficient of the cooling water was determined, and then the mean condensationheat transfer coefficient was calculated from the overall heat transfer coefficient.The model of a homogeneous two-phase mixture of liquid and vapor, and Prandtl's principle of analogy between the momentum and heat transfer were used to establish the type of the correlation. Adopting the methods of the gradually linear regression and F-level evidence testing, the present paper proposed the dimensionless correlation to predict the relationship among the mean Nusselt number, Prandtl number, Kutateladze number and the dimensionless tube length.  相似文献

Fingerprint Classification Based on Genetic Programming
LIU Xiao
(Jiangsu Second Normal University, Nanjing, Jiangsu, 210013, China)
Abstract: A novel algorithm for fingerprint classification is proposed in this paper, which classifies fingerprints into five types: arch, left loop, right loop, whorl, and tented arch. First, the preprocessing of fingerprint images is carried out to enhance the image ; then a method based on GP ( genetic programming) is adopted to generate new features from the original dataset without any prior knowledge; finally BP (Back Propagation) network and SVM (Support Vector Machine) classifiers are used to classify fingerprints. This method can improve the computation efficiency and accuracy. The experimental results show that the algorithm used in the FVC2004 database, in the absence of any rejection of case classification, the accuracy rate of this classification reaches 93.6%.  相似文献

Successful innovation management depends upon both, the intrinsic attributes of the new product to be marketed and the firm's internal performance like cost management, timely delivery and quality assurance. The impact of these latter aspects is frequently neglected in the design of models for supporting decision making in innovative firms.A model is outlined to study the market response of different manufacturing policies for innovative goods. It allows e.g. the evaluation of an aggressive strategy with large production capacities from the outset, or a more tentative behavior to. avoid the pressures stemming from high fixed cost and the risks of eventually idle capacity.  相似文献

Under economy financialization, we used the macroeconomic analysis framework which was derived from aggregate supply-aggregate demand model to explore the formation mechanism of commodity financialization. Moreover, we used VAR model to study the systematic relationship between commodities and macroeconomic factors. The excessive money will have a positive impact on commodities' prices. In addition, we explain the new manifestations of the commodity markets from the aspects of both commodity spot market and derivative market under the influence of commodity financialization. In the end we conclude the above content and pro- mote relative political suggestions to cope with commodity financialization.  相似文献

To understand the status of doctors’ salary satisfaction in county?level public hospitals of Anhui Province, we investigated a total of 1 605 clinicians from 11 county level public hospitals by questionnaire survey ,and the survey data were analyzed by factor analysis and influence factor analysis using SPSS software, exploring the major influencing factors of doctors salary satisfaction. It showed that the overall salary satisfaction score of doctors was 1.94±0.49. Salary satisfaction was summarized into three factors, which are salary level, welfare, salary structure and management according to the influence degree. The score of these factors in order was salary structure and management(2.76±0.83), welfare(1.59±0.88), salary level(1.48±0.83). The influences of gender, age, education attainment, working years, and employment type on salary satisfaction and overall salary satisfaction were different. The overall salary satisfaction of doctors in county?level public hospitals was low. It is suggested to raise the salary level of doctors, enrich the welfare subsidies, adjust and improve the salary structure, establish a reasonable performance appraisal system and attach importance to the influence of education attainment, working years and employment type on salary satisfaction.  相似文献

SummaryAfter describing the economic institutions for agriculture and industry in China before 1978, this paper points out the reasons for and the key elements of economic reform. It then discusses the major issues currently being deliberated by the leading economic reform officials regarding reform of the price system, the administrative structure of state-owned enterprises, the banking system and macroeconomic control mechanisms, and foreign trade and investment. Finally future prospects of the reform and of China's economic development will be indicated.The transformation of the economy of the People's Republic of China from a planned to a more market-oriented economy is perhaps the most significant development in world history during the last quarter of the twentieth century what was the Chinese economic system like before 1979? why were reforms introduced? what are their essential elements? what are the important issues currently addressed by the reform officials? what are the future prospects? These are the questions to be answered in this paper. The Chinese economy is a complicated entity with many dimensions. Space permits discussion of only those aspects pertinent to the transition to a more market-oriented economy.  相似文献

Textbooks, as the most important learning sources, are supposed to lead students to acquire knowledge by themselves. This paper, by analyzing the characteristics of the previous textbooks, puts forward that the editor might as well transfer teaching materials into learning materials while compiling textbooks. The specific measures include: first, to render content in the light of the learning process; second, to reserve the margin for students to do learning easily via textbooks ; third, to innovate the style and layout through the form of links and highlight inquiry - based learning and autonomous learning; fourth, to follow the learning methods and improve students' learning ability.  相似文献

( 1 ) CHEN Du-xiu's Ponderation and Criticism on the Revolution and Construction Mode of Soviet Russia LUO Xiao-hui (004) Hunan University of Technology, Zhuzhou Hunan 412007, China Abstract: CHEN Du-xiu disapproved Comintern's guiding Chinese revolution with the experience and mode of Russian revolution. He advocated that a backward country develop Capitalism first to construct Socialism and criticized Stalin's dictatorship and the highly centralized political system of the Soviet Union. CHEN's advocation and criticism, most of which was objective and practical, shows his good insight, precise prediction and conscience which have brought about his tragedy. Key words: CHEN Du-xiu; mode of Soviet Russia; Socialism; democracy; Stalin  相似文献

Confucius and Official Book System (Ⅱ) :Confucius' Historical Contribution to Book Dissemination
Confucius took six governmental works as private teaching materials. As a result, this turned out to form six kinds of folk books, and was the first important desertion in the ancient system of Official Book. By giving lectures and folk writing, Confucius took a critical first step to end the system of Official Book. Under that sys- tem, Confucianism was not and could not be any personal writings. It was only a collective work of many scholars. Comparing Official Books with other books in Han Dynasty, the author believes that Confucius dicta- ted his ideas to his disciples rather than recording the text. The evolution of Confucianism is a learning of the collective work, which has been affected by the three objective factors of Official Book System. It will provide a new way to rediscover the Pre-qin academics and philosophers in Interpreting Confucius views on ideas of public dissemination.  相似文献

The Style of Study and the Philosophy and Social Science Research SHANG Zhi-xiao (Shandong Provincial Party School ,Jinan 250001 ,China )
The Style of study is the attitude towards scientific theories, in essence, is the theory which link with practice. Philosophy and social science research must adhere to the scientific study style of integrating theory with practice ,which is not only the need for theoretical innovation, but also for the precondition of theoretical innovation. For these reasons, philosophy and social sciences should seriously change their work style, establish a good style of study, and improve the style of the article.  相似文献

This paper mainly focuses on investigating to what extent and how listening comprehension was affected by students‘anxiety, which was considered to be one of the factors to which EFL/ESL teachers must pay attention. The author of the thesis used a questionnaire on trait anxiety and one on state anxiety to look into students‘anxiety levels exhibited in the listening part of the College English Band IV Test. 52 subjects from the Inner Mongolia (Polytechn:c) University of Technology were involved in the investigation. Data collected from the investigation were statistically analyzed using SPSS 10. 0. The research findings indicate that anxiety is a factor to affect the students’ listening performances, that means the reduction of trait anxiety levels may facilitate listening performances of the students. Visualization is a promising technique for treatment.  相似文献

Zhai Yongming, the herald of feminine poem writing in Mainland China, cheering for her consciousness of dark, blazed a trail for the poems of confessional style, which could be described as crazy and unscrupulous. Later, this style was transformed into a style of drama in which one can find intercourses and dialogues. The two different poetic styles imply two specific paradigms for the history of Chinese contemporary poems. The author adheres to the method called "the few is the numerous", with which she exposes many different aspects of life. Her works, mosf of which are both reserved and uncommunicative, and tempt the audience to thinking deeply of them. For these reasons, she can be recognized as one of the poets with both inner powers to write and outstanding profundity.  相似文献

According to the reform and opening-up policy to the outside world in our country,English has become a more common communication tool in today’s society.The schools at all levels also enhance the English teaching,even the kindergarden.It is important to improve the teaching quality.Teachers have to pay more attention to the research of language teaching.In English teaching classroom,teachers should not only use the oral language and written language to deliver the information,but also make use of the silent body language.Body language not only deepens the verbal language,but also takes an unsubstitutive effect on the verbal language.  相似文献

The exact solution for the combined KS and KdV equation is obtained via introducing a simple and effective nonlinear transformations.This method is very concise and primary and can be applied to other unintegrable nonlinear evolution equations. It is common knowledge that the Korteweg de Vries(KdV) equation [1] (1) has been proposed as model equation for the weakly nonlinear long waves which occur in many different physical systems; the Kuramoto-Sivashinsky (KS) equation is one of the simplest nonliaear partial differential equations that exhibit Chaotic behavior frequently encounted in the study of continous media [2-4] . Many interesting mathematical and physical properties of eqs. (1) and (2) have been studied widely. But, in several problems where a lonq wavelength oscilatory instability is found, the noulineai evolution of the perturbations near rriticality is governed by the dispersion modified Kuramoto-Sivashi nsky equation(3)ft is clear that this equation is a combination of the KdV and KS  相似文献
