The policy of cost-sharing by in- dividuals was tried out in many countries. However, empirical studies have shown that the policy has, to a certain de- gree, negative effects for the poor in accepting higher education costs. This paper points out it is the mismatch between tuition fees and the ability to pay that causes the problem. Using two dimensions of group and time to pay, a mode sys- tem, including seven modes for the individual to share the cost of higher education, was constructed. It is suggested that only three modes of pay-immediately have been carried out in China and they all have same shortcomings. To try new modes and exercise different modes synthetically will be meaningful for solving the questions that exist in the current policy.展开更多

In principle, this model is a one-way model, and hence provides satisfactory accuracy for problems where the forward scattering dominates. At the same time, this model provides an efficiency gain of an order of magnitude or more over two-way coupled-mode models. This model can be applied to three-dimensional range-dependent problems with a slowly varying bathymetry or internal waves. A numerical example of the latter is demonstrated in this work. Comparisons of both accuracy and efficiency between the present model and a benchmark model are also provided.展开更多

The equipment used here was Voluson 530D 3DUS imaging system and 3D volume trahsducer with frequency being 3. 0-5. 0 MHz. The 3DUS rendering method was surface mode. The results showed that: 1 ) Surface mode of 3DUS could demonstrate clearly the anatomical characteristics of the region-of-interest (ROI) and the inner wall of lesions or organs that contained fluid. The anatomic details, such as location, size, shape, and number of the ROI, could be visualized intuitively; 2) The outer anatomic features (e. g. contour, edge, configuration, etc. ) of some organs or lesions surrounded by fluid could be displayed clearly. It could be concluded that surface mode on 3DUS could provide more diagnostic information than two-dimensional ultrasonography (2DUS) in some cases and could served as a beneficial supplement to ZDUS in clinical practice.展开更多

It is shown that the left-handed helical modes play a major role on the spectral transfer properties of turbulence when the generalized helicity and magnetic helicity are both positive. In contrast, the right-handed helical modes will play a major role when both are negative. Furthermore, we also find that if the generalized helicity and magnetic helicity have opposite signs, the tendency of equilibrium spectra to condense at the large or small wave numbers will be presented in different helical sectors. This indicates that the generalized helicity dominates the forward cascade and the magnetic helicity dominates the inverse cascade properties of the Hall MHD turbulence.展开更多

Therefore, three main ways to deepen the university-enterprise collaborative education are proposed: The first is to improve and implement the local government's policy guarantee system and incentive measures, fully mobilize and stimulate the enthusiasm and initiative of enterprises to participate in university -enterprise collaborative education;The second is to innovate the long-tenn operation mechanism of university-enterprise collaborative education, and to open up the last mile of educating and employing people;The third is to innovate the university-enterprise joint university-running mode and build a system of engineering talents that integrates innovation and practical capabilities.展开更多

The agricultural and forestry colleges and universities must realize the transformation and innovation of moral education mode,reshape the main position of moral education of college students,rebuild the core value of moral education which pays close attention to the growth of individual life,and reconstruct the way of realization of moral education in colleges and universities.

文摘Using the Fourier helical decomposition, we obtain the absolute statistical equilibrium spectra of left- and right-handed helical modes in the incompressible ideal Hall magnetohydrodynamics (MHD). It is shown that the left-handed helical modes play a major role on the spectral transfer properties of turbulence when the generalized helicity and magnetic helicity are both positive. In contrast, the right-handed helical modes will play a major role when both are negative. Furthermore, we also find that if the generalized helicity and magnetic helicity have opposite signs, the tendency of equilibrium spectra to condense at the large or small wave numbers will be presented in different helical sectors. This indicates that the generalized helicity dominates the forward cascade and the magnetic helicity dominates the inverse cascade properties of the Hall MHD turbulence.

文摘The development of Internet finance has made the financial environment faced by college students more complicated.The level of financial literacy best reflects a person's sensitivity to the financial environment and flexibility to respond to financial events.Therefore,to improve the financial literacy of college students,popularizing financial knowledge is bound to become the key content of general education and teaching work in contemporary colleges and universities.In this article,taking 400 undergraduates from Yangtze University as the research object,the participation in online lending and the mastery of financial knowledge were investigated and analyzed,then the current teaching situation of financial literacy courses was introduced,and finally,a number of suggestions to improve the teaching reform of financial literacy were put forward.

文摘By grasping the characteristics and laws of the growth of excellent talents,this paper objectively analyzes the current situation of ideological and political education and the problems existing in the innovation process of ideological and political education.In accordance with the inherent requirements of the innovation of ideological and political education in colleges and universities,efforts should be made to build a specific path for the innovation of ideological and political education in colleges and universities,which is consistent with the training mode of excellent and innovative talents.
文摘College English courses are an important part of college education with humanistic and instrumental characteristics.Outcomes-based teaching method is oriented by students’learning output,which has been applied in education for decades.Students achieve the outcomes through communication,cooperation,and exploration from which their initiative,confidence,and learning ability are improved.It is instructive to help student both develop language skills as well as enrich the knowledge of Chinese traditional culture.This paper explores the necessity of moral education and relates them to College English course on the basis of outcomes-based teaching method.It is intended to help teachers understand the theory and philosophy of outcomes-based education and put it into moral education practice in their instructional planning,teaching,and assessment of students.
文摘At present, China's local engineering universities have basically formed five modes of collaborative education between Engineering Universities and Enterprises, namely the mode relied on university-enterprise alliance, the mode centered on the "Excellent Engineer Education and Training Program", the mode rooted in key disciplines, the mode based on the innovation and entrepreneurship education activities and the mode of carrying out international joint training, etc. However, in the process of university -enterprise collaborative education, there are still some shortcomings such as long-term deficiency, low fit and insufficient system. Therefore, three main ways to deepen the university-enterprise collaborative education are proposed: The first is to improve and implement the local government's policy guarantee system and incentive measures, fully mobilize and stimulate the enthusiasm and initiative of enterprises to participate in university -enterprise collaborative education;The second is to innovate the long-tenn operation mechanism of university-enterprise collaborative education, and to open up the last mile of educating and employing people;The third is to innovate the university-enterprise joint university-running mode and build a system of engineering talents that integrates innovation and practical capabilities.
