R744 is the most competitive, and R744 is the most ideal when flammability and toxicity are strictly limited. There are some problems in the current R744 heating system, for example the pressure at the heat release side is often more than 10.0MPa. High operating pressure brings high cost....

For hydrocarbon-fueled turbojet engines with a precooling technology, the precooling technology with a low-temperature endothermic fuel is a great potential way to solve the problem of sharp reduction of the specific impulse caused by the insufficient heat sink of the hydrocarbon fuel. To study...

A hypersonic vehicle, its flight state is changeable, which is often related to the heat load change of chamber wall. Thermal and flow response characteristics during flight state change are investigated in this research experimentally by utilizing the electrically heat experiment system. It is...

The insight information of subcooled flow boiling is very important for the development of boiling crisis mechanistic model. In this paper, visual experiment is carried out in a vertical square channel with a heating rod with diameter of 9.5 mm. Based on the near-wall bubble behavior captured by...

Over last ten years, the media has gradually been playing an irreplaceable role in economic society. As efficient means of improving insufficient judicial protection, media plays an important role in disseminating public information, restraining the government’s behavior, shaping corporate...

This paper offers a new way of assessing government cash transfers using a social welfare function framework. It demonstrates how one can use social welfare functions to measure the efficiency of such program s without requir ing the specif ication of a poverty line or particular poverty...

The Economic and trade relationship between the EU and ASEAN is determined by on the ¡°soft power¡± strategy of the EU, which is different from that of the US and Japan. On the other hand, the relationship is also a reflection of economic interest demands of the EU¡¯s trade and investment....

The impact of the transnational corporations¡¯ R & D investment on innovation capability of the high-tech industry in Gansu Province is analyzed in this paper by the production function model in OLS regression analysis method from the view of the spillover effect and crowding effect. It is...

This paper applies spatial correlation method in spatial statistics and GIS technology to analyze special structural form and evolution process of regional economy of Pan-Linxia region. Morphological analysis of spatial structure shows the correlation between economic development level of Linxia...
