The expansion of the world trade organization and the growth of multinational corporations have promoted China＇s market economy to head for internationalization; the exchanges of all countries＇ science and technology, culture, and education have become increasingly frequent and beyond the borders very early, so opening-up has become a world trend. China is playing an important role in this historical process. In this situation, the importance of language translation is increasing day by day, and an unprecedented prosperous situation has especially appeared to the interpretation. In order to accord with this new historical situation, many colleges and universities have set up language translation program and have offered interpretation course. To promote the economic development of China and train more senior interpreters, the studies of interpretation teaching and the improvement of interpretation teaching quality have been particularly important. In this paper, the relationship among memory, note-taking, and psychological factors are analyzed.展开更多

The relationship between the force exerted on the brush and the resulting brush deformation is analyzed and a spring-mass model is used to build a model of the 3D Chinese brush. The 2D brush footprint between the brush and the plane of the paper or object is calculated according to the deformation of the 3D brush when force is exerted on the 3D brush. Then the 3D brush footprint is obtained by projecting the 2D brush footprint onto the surface of the 3D object in real time, and a complete 3D brushstroke is obtained by superimposing 3D brush footprints along the painting direction. The proposed method has been suc- cessfully applied in a virtual 3D interactive drawing system based on force feedback technology. In this system, users can paint 3D brushstrokes in real time with a Phantom Desktop haptic device, which can effectively serve as a virtual reality interface to the simulated painting environment for users.展开更多

High Energy Phys. 1708, 001(2017)] showed that the planar flavored Ahanory-Bergman-Jafferis-Maldacena(ABJM)theory is integrable in the scalar sector at two-loop order using coordinate Bethe ansatz. A salient feature of this case is that the boundary reflection matrices are anti-diagonal with respect to the chosen basis. In this paper, we relax the coefficients of the boundary terms to be general constants to search for integrable systems among this class. We found that the only integrable boundary interaction at each end of the spin chain aside from the one in ref. [J. High Energy Phys. 1708, 001(2017)] is the one with vanishing boundary interactions leading to diagonal reflection matrices. We also construct non-supersymmetric planar flavored ABJM theory which leads to trivial boundary interactions at both ends of the open chain from the two-loop anomalous dimension matrix in the scalar sector.展开更多
