It was shown that the evaporation curve of real gases resides between those of Van-der-Waals and Berthelot gases. The generalized Van-der-Waals-Berthelot equation is suggested, which not only qualitatively but also quantitatively describes evaporation curves of real gases. It was also shown that the generalized Van-der-Waals and Berthelot equation well describes other characteristics of real gases.展开更多

The results show that the US financial market risk premium is the most important determinant of changes in the nominal rate of return, while the US dollar exchange rate and the bulk commodity price are the two key determinants of changes in the real rate of return. From empirically based research, one may conclude that the loose monetary policy of the US Federal Reserve increases China＇s foreign exchange reserves＇ nominal rate of return but decreases the real rate of return and that the European debt crisis has an uncertain impact on China＇s foreign exchange reserves＇ nominal rate of return but may well raise the real rate of return.展开更多
