Étude des performances du cycle frigorifique régénératif de Brayton utilisant un nouveau matériau composite Mn-Fe-P-Si avec hystérésis thermique comme milieu de travail

MnFeP(As, Ge, Si) series compounds are three kinds of MnFe-based magnetocaloric materials, which have giant magnetocaloric effect. In this work, the experimental characteristic curves of new style Mn-Fe-P-Si materials, numbered as 1: Mn_1.32Fe_0.67P_0.52Si_0.49, 2: Mn_1.37Fe_0.63P...

Maritime broadband communication: Wireless channel measurement and characteristic analysis for offshore waters

For a long time, the development of maritime communication has been restricted by the low data rate, high-latency and high cost of the current communication systems. The upgrade of new generation mobile communication technologies is attracting more and more attention to conduct a shore-based broadband mobile communication network with high...
