Such increase in e-business created a gap between the demand and supply of BE talents, esp. those of e-business. Yet on the other hand, most academies with BE majors in China are sticking to the traditional schedule of talent cultivation, focusing on the language skills and cultural knowledge. Some colleges have detected new modes for such BE talent cultivation by integrating foreign trade firms into the BE courses and have provides us with many valuable inspirations. Study of the cases can offer more practical tips on such cooperation, so far as the academies are ready to adopt to the new situation and reform their teaching schedules. Study shows that such cooperation is beneficial to the academies, to the firms, and above all, to the students.展开更多

We first put operators into their Weyl ordering through the Weyl-Wigner quantization scheme, and then we convert the Weyl ordered operators into normal ordering by virtue of the normally ordered form of the Wigner operator.展开更多
