For the motion of a sphere on a rough horizontal plane, in the previous paper [1]. the author aimed at providing approximate analj'tical solutions while the nutation is neglected. In this paper, the control equations.for the sphere with nutation have been deduced on the basis of paper [1]. Through the medium of solving these equations, the conclusion.for the velocity o[" contact point #1 paper [I] is still proved true for the case with nutation. What is more. some interesthlg results are gained, for e.vample, the velocity of centre and contact point is relative to the angular veh~city o] sphl and halation." the direction of velocity of centre and contact point is constant. Under the condition which is supposed to be weak mctation, the approx#nate analytical solutions are obtahwd, so that the results qf paper [I] is proved to be true. Now from the principle of moment of momentum about its center of mass other equations can be deduced. The moment of momcmum of the sphere about point O is G.=J~= -loi -J Osin0j +l (r (2.12)where J is. the moment of inertia of the'sphere with respect to the diamttcr and equals

In recent years, with the continuous development of modern educational technology, it has played an important role in college education and is a basic way to promote the development of college education. The development of modern educational technology and education and teaching reform complement each other and form a joint The fundamental problem of the development of educational technology in colleges and universities, in order to realize the modernization of college education and occupy the commanding heights of modern education, it is necessary to have a deep understanding of the influence of modern educational technology in the educational activities of colleges and universities. This article explores this.

Research is an important part of an academic career, yet it is not always frequently practiced by most students. This descriptive-correlational research aimed to find out the external factors that influence students’ attitudes toward research. We sampled 201 undergraduates at Wenzhou-Kean University and analyzed their responses to the questionnaire in order to determine the relationship between possible factors and their attitudes. The results revealed that the external factor of the training environment has a moderate positive influence on research attitude, while support from the university has a strong positive influence on research attitude. Specifically, factors of faculty support, curriculum design, on-campus academic activities, library service, and financial support all moderately influence students’ attitudes towards research in a positive way. The most salient influential factor of all is faculty support. The results suggested that to improve students’ attitudes towards research, sufficient support is vital, especially academic and financial support. Therefore, to externally encourage students to conduct academic research, faculty and university could give more consideration to support provision.
