According to the characteristics of the actual air flow and temperature change in gob, a two-dimensional temperature field model of the gob was built, and the relational model between the air pressure of intake and outlet of the gob and the atmospheric pressure was established, which was introduced into the boundary conditions of temperature field to conduct calculation. By means of analysis on the simulation example, and comparison with the traditional model, the results indicate that atmospheric pressure change had notable impact on the distribution of gob temperature field. The laboratory test system of gob temperature field was constructed, and the relative error between simulated and measured value was no greater than 9.6%, which verified the effectiveness of the proposed model. This work offers theoretical basis for accurate calculation of temperature and prediction of ignition source in mine gob, and has important implications on preventing spontaneous combustion of coal.展开更多

A simple interpretation was drawn of artistic characteristics on temple garden in Kunming during the Ming and Qing dynasties via analytical investigation on many factors which influenced the development of garden of Dynasties of Ming and Qing. Then we have reviewed the elemental traits of temple garden built at that time,put forward some constructive suggestions on how to protect and develop those temple garden now still exist in Kunming.展开更多
