作者： Anett Kozjek-gulyás Pázmány Péter Catholic University Hungary

The present paper analyzes the strategic choices for learning Chinese by 300 Hungarian university students. The survey summarizes the most often used Chinese language learning strategies and verbal language learning strategies of Hungarian language learners one by one. With the help of the method of multidimensional scaling, the survey got to the result that the preference of the general language learning strategies is characterized by a strong opposition. In the case of the choice and use of three strategies--the social, the meta-cognitive and the cognitive strategies, language learners prefer a combined choice or non-choice. While in the use of the emotional, compensation and memorization strategies, a strong opposition emerges. Those using memorization strategies less prefer the emotional and the compensation strategies. This is true vice versa as well, those using emotional strategies, use memorization and compensation strategies less often. While the relation of the general language learning strategies was characterized by a certain opposition, in the use of the verbal strategies a strict continuity could be detected. Hungarian language learners consider the use of almost all verbal strategies with few exceptions to be successful in their communication. The results of the Variables path analysis with Partial Least-squares Estimation （LVPLs） model revealed all those connections that structurally exist among the three exogen background latent variables （language level, language learner style and the ascriptive background） and the two endogen latent variables （the language learning strategies and the verbal strategies）. All of these latent variables measured with several manifest variables of the second exogen background variables, the language learning style showed the biggest affect to strategy use, this variable influences the successfulness of the learning of Chinese most strongly.

热泵在多年冻土地区工程中的应用(英文)

冰川冻土 2004年第S1期26卷 220-226页

作者： sergei guly North-Eastern Research station Melnikov Permafrost Institute SB RAS Gagarin St. 12 Magadan 685024 Russia

The inclement climate and permafrost have a strong influence on human activities and life in cold regions. It is important to adjust to these conditions in such a way as to minimize adverse environmental impacts. In order to maintain the ecological equilibrium, various technologies have been developed which involve the use of the ’natural cold’ for solving difficult engineering problems. Heat pumps hold much promise in this context. They can help protect the environment from the thermal effects of human activities and, unlike the conventional refrigeration devices; the produced heat can be utilized. They also provide a solution to another problem vitally important for the northern regions - saving of fuel and energy resources. In case of global warming with an increasing need for artificial refrigeration, the use of heat pumps will be the most economical solution, preventing catastrophic loss of structural stability virtually without additional costs.
