On the Models of the Bilingual Education and Their Implementation Conditions

This paper carefully probes into the main models of the bilingual education in the world, deeply analyses the conditions and requirements on the implementation of the bilingual education in our schools, and clearly differentiates TEFL and TESL as well as bilingual education. The writer thinks that in China we teach English as a foreign language instead of a second language, that the bilingual education is the supreme level of the foreign language acquisition, and that the final goal of the bilingual education is to make learners simultaneously think and use Chinese and English in both ways as well as communicate with one another in two languages according to the situational context. Therefore, it is not easy to practice the bilingual education in a country like China, which is still poor in the English language context. But the situation will change as China enters WTO and the globalization speeds up.

Features of hardware implementation of quasi-continuous observation devices with discrete receivers

This article proposes an approach to the formalization of tasks and conditions for the hardware implementation of quasi-continuous observation devices with discrete receivers in remote sensing systems.Observation devices with a matrix are used in medicine,ecology,aerospace photography,and geodesy,among other fields.In the discrete receivers,the sampling of an image in the matrix receiver into pixels leads to a decrease in the spatial information of the object.In a greater extent,these disadvantages can be avoided by using photosensitive matrix with a regularly changing(controlled)density of elementary receivers-matrix(RCDOER-matrix).Currently,there is no substantiation of the tasks and conditions for the hardware implementation of RCDOER-matrix.The algorithmic formation of a quasi-continuous image of observation devices with the RCDOER-matrix is proposed.The algorithm used a formal pixel-by-pixel description of the signals in the image.This algorithm formalizes the requirements for creating a photosensitive RCDOER-matrix of a certain size,as well as for changing the mechanism for forming and saving a frame with observation results.The application of the developed method will allow multiplying the pixel size of the image relative to the pixel size of the RCDOER-matrix.Developed algorithms for RCDOER-matrix are supplemented by formalizing the tasks that arise when creating prototypes.In addition,the conditions for hardware implementation are proposed,which ensure the completeness of registration of the observation picture,and allow avoiding excessive pixel measurements.Thus,the results of the research carried out approximate the practical application of RCDOER-matrix.
