The major works are as follows: 1 The 3-D numerical model of U-sharp flow passages is set up. The single-phase fluid flow and heat transfer are simulated for the U-sharp smooth and rib-roughened flow passages with FLUENT software. Their performance curves, temperature field and velocity vector are obtained and the local heat transfer and flow pressure-drop distribution along flow passage are analyzed. It is revealed that the ribbed flow passages can enhance heat-transfer and make the temperature more uniform, but it increases the pressure-drop to more extent. 2 The influences of diaphragm depth, channel width and board spacing on the performance are investigated.

The relationship between mantle fluid and U ore-forming was studied preliminarily,according to the results,the author considered theΣCO_2 of mineralizer and heat source came from mantle,which is because upwelling mantle forced by crustal extention and deep-seated faulting produced melt blending with lower crust,during this process,mantle provided the heat and releaseΣCO_2 to crust through outgassing.U mainly came from mantle-curst fluid formed by mantle-curst melt blending and the wall rock during fluid uplift.H_2O mainly generated from mantle fluid and the wall rock during mantle fluid uplift,and partly from atmospheric water in the late period of ore-forming.
