The purposes of such policies are： to accelerate the reform of mineral resource royalties and advance the competitive transfer of mining rights; to promote the reform of the natural gas price, introduce cost supervision on long-distance natural gas pipeline enterprises in the area of gas pipeline transportation, and strengthen the regulation qf the distribution price; to liberalize the import qf crude oil in an orderly manner, increase the allowable volume of non-state trading crude oil imports, strengthen the supervision and periodically pause the approval of the right to use imported crude oil; and to enhance environmental protection.展开更多

The Newtonian heat transfer formulation is coupled with the classical heat conduction equation to predict the heat transfer process within micro-droplet. Based on the numerical solution by finite difference method with implicit Euler scheme,the temporal evolution of thermal information inside micro-droplet is obtained including the temperature distribution, cooling rate, temperature difference and gradient. To quantitatively reveal the mechanism how the various factors affect the heat transfer of micro-droplet, the effects of physical properties of liquid metal and cooling gas as well as the micro-droplet size are studied.As the important indicators of heat transfer process, the cooling rate and temperature difference are acquired to systematically investigate the relationship between thermophysical properties and heat transfer process of different metallic micro-droplets.展开更多
