关于高等院校双语教学模式的创新

在应试教育的模式下,学生往往会学英语,但不会用英语。开展双语教学可以提高学生应用英语的能力。从分析传统双语教学模式带来的弊端及目前高等院校双语教学现状入手,根据基本教学模式提出了创新的"动态化模块的双语教学模式"。

The matrix representation for the mathematic structure of Shannon＇ s information measures

Shannon＇ s information measure is a crucial concept in Information Theory. And the research, for the mathematics structure of Shannon＇ s information measure, is to recognize the essence of information measure. The linear relation between Shannon＇ s information measures and some signed measure space by using the formal symbols substitution rule is discussed. Furthermore, the coefficient matrix recurrent formula of the linear relation is obtained. Then the coefficient matrix is proved to be invertible via mathematical induction. This shows that the linear relation is one-to-one, and according to this, it can be concluded that a compact space can be generated from Shannon＇ s information measures.

The feature on the posterior conditional probability of finite state Markov channel

The feature of finite state Markov channel probability distribution is discussed on condition that original I/O are known. The probability is called posterior condition probability. It is also proved by Bayes formula that posterior condition probability forms stationary Markov sequence if channel input is independently and identically distributed. On the contrary, Markov property of posterior condition probability isn＇ t kept if the input isn＇t independently and identically distributed and a numerical example is utilized to explain this case. The properties of posterior condition probability will aid the study of the numerical calculated recurrence formula of finite state Markov channel capacity.
