In this paper, we conduct research and survey on the common problems and corresponding solutions for the Chinese-foreign cooperative education management. The training objectives of cooperation in running schools only to adapt to the society and education development rule for their healthy development. According to the economic development and social needs, the Chinese-foreign cooperation in running schools of talent cultivation, mainly reflected in the advanced nature of the program. Our research proposed novel solutions to the general problems and issues need to be solved for the Chinese-foreign cooperative education management which will be meaningful. 展开更多

SINOPEC is an integrated energy and chemical company engaging in upstream,midstream and downstream operations. The business of SINOPEC covers E&P of oil and gas, refining,chemical production, as well as sales and marketing of refined oil products. In the field of oil andnatural gas exploration and development, there are 13 upstream subsidiaries in SINOPEC. By the endof 2003, the proven reserves of crude oil were 3,257 mmbbls, and natural gas reserves totaled2,887.6 bcf. The oil and gas production in 2003 included 270.96 mmbbls of oil and 187.7 bcf ofnatural gas. In the area of middle-stream operation, SINOPEC has 33 refineries. The total capacityof crude distillation is 153.9 million tons/year, about 51% of the total distillation capacity inChina. In 2003, 123.5 million tons of crude oil was processed, around 53% of total crude processedin China. 展开更多

The intensive and inappropriate use of water, fertilizers and phytosanitary products is sources of water and soil pollution. It is thus necessary to improve the management of irrigation water in order to optimize its use and productivity, especially in regions where water resources are becoming increasingly scarce. The water flow and non-reactive solutes’ transport simulation under drip irrigation were carried out in a 3-layered soil profile distributed from top to bottom<em> i.e</em>., sandy, sandy-silty, silty-sandy-clay. The aim of this study was thus, to provide a good practice of water management associated with solutes’ application, in order to retain as much solute as possible in the root zone, which will increase the residence time of the solutes. Three treatments of water flux corresponding to 100% <em>ET</em><sub><em>c</em></sub>, 75% <em>ET</em><sub><em>c</em></sub>, 50% <em>ET</em><sub><em>c</em></sub>, combined with 100 mmol /L/ m<sup>2</sup> of NPK and 246 mmol/L/m<sup>2</sup> of urea applicable in two doses, were carried out over a period of 110 days corresponding to the duration of the cropping cycle for the intermediate variety of maize. The 100%<em> ET</em><sub><em>c</em></sub> and 75% <em>ET</em><sub><em>c</em></sub> treatments cause more loss of water and solutes, because of the sandy texture of the soil. However, a 50% <em>ET</em><sub><em>c</em></sub> water flux would reduce more water loss through drainage, and solutes’ loss due to leaching beyond the root zone, which would increase the residence time of solutes in the soil profile. Application tests of the NPK solute on different days before the 15<sup>th</sup> day after sowing were also carried out according to the technical itinerary for maize production in Burkina Faso, in order to find a favorable day for application of the solute. For the different dates of solute’s application, there was more loss of the solute as we approach the 15<sup>th</sup> day after sowing. To limit this loss and increase the residence time of the NPK solute, one could apply the solute without first supplying water, the day before and the day after the date of solute’ injection. Or, one could amend the soil with organic matter to improve its retention capacity of water, and the solutes’ residence time in the soil. 展开更多
