One of the most attractive advantages is that this technique can accelerate tile writing speed, e.g. 1×32 Damnlann grating can be 32 times faster than the single laser scanning system. More importantly, the uniformity of the multi-beams-written lines is much better than the single la.ser beam scanning system in consideration of the environlnental effects such as air turbulence, thermal instability, etc. Using the SDL system, a three-port high-efficiency beam splitter at visible wavelengths is fabricated quickly, and the theoretical and experimental diffraction efficiencies are both higher than 90%. Therefore, SDL should be a useful tool for fabrication of large-sized gratings.展开更多

English courses should not only lay a good foundation for language, but also pay more attention to the training of practical language skills, especially the ability to use English to deal with daily and foreign business activities. Higher vocational college students who are relatively weak in their basic English writing are particularly prominent,far from the regulated requirements. Because of the poor basic learning ability of higher vocational college students, it is very important for teachers to supervise and get feedback. But the ratio of students to English teachers in some higher vocational colleges has reached 130 : 1, so it is becoming more and more important for teachers to adopt computer aided correction composition system.展开更多

Teachers, consequently, spare no pains to give feedback, expecting their students would make progress in their writing, but it seems that things go contrary to their wishes. Although there are various complicated factors contributing to the situation, one of the important factors lies in the teachers, a number of whom do not grasp a systematic and effective mechanism of delivering feedback on EFL student writing. Much importance has been attached to Chinese EFL student writing, however, rare attention has been paid to conducting research on concrete ways of delivering feedback on Chinese EFL student writing in China. Therefore, this paper serves to fill the gap, mainly devoting itself to exploring concrete methods of delivering teacher feedback on EFL student writing.展开更多

This system which is used in network consists of four modules, including task module, structure training module, text training module and study evaluation module. With the advantages of instantaneity, interactivity, authenticity and adequation of learning resources, the applied writing abilities of the students can be improved effectively by using the network system. And the problems during the process of applied writing teaching, for example, the teaching contents lose contract with social life, the textbook contents are lack of innovation, and writing training goes against cognizing system, can be solved effectively.展开更多
