A Comparative Study of School-enterprise Cooperation and Work-study Combination System Construction in Vocational Education at Home and Abroad

In this paper, based on the experience and practice of school-enterprise cooperation in developed countries, the current situation ofschool-enterprise cooperation in China was studied. Through analysis and comparison, the mode of school-enterprise cooperationsuitable for higher vocational education in China was explored to promote the development of higher vocational education inChina. The current situation and existing problems of work-study integration in higher vocational education in China wereanalyzed, and different modes of work-study combination in foreign higher vocational education were compared. Under thecurrent situation, earnestly studying and drawing lessons from the experience of foreign developed countries is of greatsignificance to the continuing development of school-enterprise cooperation and the talent training mode of work-studycombination in national model colleges and key universities.

Friction properties of groove texture on Cr12MoV surface

To analyze the influence of surface texture on friction properties of Cr12 Mo V', ordinary grinder and spinning technology were adopted to obtain the grooved surface morphology of samples, and then the impact of spindle speed and feed in z-direction on surface morphology in the process of spinning was studied. In addition, the corresponding friction coefficient of sample was obtained through friction and wear tests. The results show that the peak clipping and the valley filling were conducted on the grinding surface, which could improve the surface roughness effectively and make the grinding trench-type wear scar more uniform. Both the area ratio of groove and groove spacing increased initially and then decreased with the increase of the spindle speed or the feed in z-direction. As a kind of micro-process, the groove could influence the friction coefficient of sample surface, whose distribution was beneficial to the reduction of friction coefficient. Compared with the surface obtained through ordinary grinding, grooved surface morphology through spinning technology was more conductive to reduce the friction coefficient, which could be reduced by 25%. When the friction coefficient of sample was reduced to the minimum, the texture of groove corresponded had an optimal area ratio and an optimal groove spacing, 37.5% and 27.5 μm, respectively.

Training of English Learning Strategy: Discussions Based on a Plan of Strategy Teaching in the Classroom of Senior School

Training of English learning strategy has become an important part in English teaching, but in the practice of the eductional activities, it does not be treated seriously. This paper tries to design a teaching plan to instruct some strategies and discuss the practical functions and meanings of learning strategy in English teaching by analyzing them.

Freedom: Perquisite of Emerson's Individualism

Emerson established a systematic philosophy of individualism at his early stage. The basic three elements of individualism described in Emerson's works are: freedom, self-identity and independence to others. Freedom, including the freedom to think and act, is the perquisite of the realization of individualism.

An ultra-low power CMOS oscillating pixel array for retina implantation

A light-controlled oscillating array for retina prosthesis is presented.The unique advantage of the circuit is that it has a lower voltage and ultra-low power consumption.And it has some other features as below:it is applicable to the natural light illumination and each pixel is an independent oscillator whose frequency is proportional to the intensity of the incident light.The fundamental characteristics of the circuit are analyzed.It is fabricated with a standard 0.6 μm CMOS technology.The experimental results indicate that the proposed circuit can be used for retina implantation,taking the place of the suffered photoreceptor in the retina of the blind and partially recovering the blind,s eyesight.
