It incorporates custom designed software for control of the magnetic field during operation such as demagnetization, field sweeping, and for data logging and analysis. Results are recorded using a 12-bit analog to digital converter and are then stored on disk. The magnetic hysteresis loop and Barkhausen noise data can be converted into important magnetic parameters: coecivity, remanence, and hysteresis loss, Barkhausen amplitude, and Barkhausen noise energy. This system incorporated with the magnetostriction, and magnetoacoustic emission, is then related with the nondestructive detection of material degradation.展开更多

This case study at-tempts to provide relevant evidence for the contribution of motivation in second language learning by looking at the success of Japa-nese study of an adult who learned Japanese at a later age 24, acquiring the target language over a 5-year period characterized bytotal exposure in Japan. The study shows that adult can still be successful to acquire second language if he is exposed to the envi-ronment and has strong motivation, and that the boundary of integrative motivation and instrumental motivation is not necessarilyclear-cut completely.展开更多

It is claimed that students＇ motivation needs to be taken into account for input to become intake and therefore is the key learner variable. During this process, authentic materials can be used to spark learners＇ motivation and interest. This article begins with different perspectives of motivation before it comes to the relationship between authentic materials and motivation.展开更多

The theoretical studies on motivation in Second Language Learning are firstly reviewed. Based on the literature review, Chinese college students＇ motivation in oral English learning is examined in terms of the Chinese context. Finally, five specific helpful strategies are put forward to facilitate students＇ optimal oral English learning.展开更多
