Sinopec Sees Significant Growth for Net Profit in 2007

China Petrochemical Corporation （Sinopec）, a leading oil refiner, posted a net profit of 70 billion yuan （9.63 billion U.S. dollars） in 2007. Sinopec made a net profit of 50.66 billion yuan in 2006. The huge profit can be attributed to cost control, resources integration and technological innovation, according to Cai Xiyou, a senior executive of Sinopec.

Chinese Oil Industry Faces New Challenges

Chinese petrochemical companies should gird for new challenges in three years, triggered by cost-competitive products flooding in from overseas, especially the Middle East countries. This advice was highlighted by company executives and association leaders during a discussion on the sidelines of a petrochemical conference organized by the China Petroleum and Chemical Industry Association in early April.[第一段]     

Changes in soil sealing in Guadalajara (Spain): cartography with LANDSAT images

The great urban and industrial development of the towns surrounding Madrid has caused an irreversible and rapid soil loss. In this paper, soil sealed evolution in Guadalajara province during the past 15 years, mainly in the capital, industrial district and small municipalities near Madrid, has been studied. This province has experimented a sharp reduction of the most fertile soils, located on the Henares valley, due to the action of new models of local and regional development. The main goal of this paper is the mapping of the covered soils in a pilot area of Spain. Supervised classification of Landsat images from 1989 to 2002 has been carried out. Geo-referred image analysis allows us to detect precisely the amount of covered soils and where this phenomenon has taken place.     

Laser heat treatments driven by integrated beams: role of irradiation nonuniformities

An analysis is given of how nonuniformities in the laser beam intensity translate into variations on the induced temperature distribution on an irradiated sample. The study involves materials with different thermal conductivities. By use of a reshaped irradiating beam obtained with a multifaceted integrating mirror, a three-dimensional numerical calculation allows us to establish both surface and in-depth temperature distributions. The results show that in the case of materials such as glass (i.e., with low thermal conductivity) large thermal gradients occur both on the surface and in depth during irradiation. However, the lateral heat flow is high enough to strongly reduce the surface gradients as soon as the laser irradiation ends. Conversely, in good thermal conductors such as nickel, the laser intensity nonuniformities induce a thermal peaking of the surface with lateral thermal gradients that are by no means negligible. Experimental evidence during laser glass polishing that confirms the numerical assessments are also provided.     

罗布泊将建成我国第二钾盐基地

全国政协副主席宋健最近在新疆考察时提出,要尽快将罗布泊建成我国第二个钾盐生产基地。 自治区计委、新疆德隆集团有限责任公司三维发展公司、巴州罗布泊矿业有限责任公司、哈密金矿、新疆地矿局和新疆有色局等单位参与了前期开发工作,另外还有八九家国内较大的企业作为股东也参与了前期投资和开发。计划2至3年内见效益,前期生产钾盐20万t/a,3年内建成50万t/a以上的硫酸钾生产能力,最终达到100万t/a目标;总投资10多亿元;与钾盐相关的产业及其它资源,如盐湖农业、罗布泊旅游业也将随之启动。 负责罗布泊总体开发的新疆罗布泊钾盐科技开发公司有关负责人坦言,罗布泊的开发难度较大,最主要是环境恶劣,路、水、电等基础设施建设投入很大。     

Color encoding for polychromatic single-channel optical pattern recognition

The common multichannel system for recognizing colored images is replaced by a color-encoded single-channel system. Amethod inspired by the Munsell color system is used for encoding the different colors as phase and amplitude functions. It is shown that for many practical cases the phase information part of the color code is sufficient for obtaining good results. An implementation based on a liquid-crystal television panel that works in a phase-modulation mode is suggested. Computer simulations that demonstrate the capabilities of the suggested method are given as well as a comparison with previously published multichannel performance.     

Degradation of alachlor and pyrimethanil by combined photo-Fenton and biological oxidation

Biodegradability of aqueous solutions of the herbicide alachlor and the fungicide pyrimethanil, partly treated by photo-Fenton, and the effect of photoreaction intermediates on growth and DOC removal kinetics of the bacteria Pseudomonas putida CECT 324 are demonstrated. Toxicity of 30–120 mg L⁻¹ alachlor and pyrimethanil has been assayed in P. putida. The biodegradability of photocatalytic intermediates found at different photo-treatment times was evaluated for each pesticide. At a selected time during batch-mode phototreatment, larger-scale biodegradation kinetics were analysed in a 12 L bubble column bioreactor. Both alachlor and pyrimethanil are non-toxic for P. putida CECT 324 at the test concentrations, but they are not biodegradable. A 100 min photo-Fenton pre-treatment was enough to enhance biodegradability, the biological oxidation response being dependent on the pesticide tested. The different alachlor and pyrimethanil respiration and carbon uptake rates in pre-treated solutions are related to change in the growth kinetics of P. putida. Reproducible results have shown that P. putida could be a suitable microorganism for determining photo-Fenton pre-treatment time.     

时效处理对Mg-5Sn-1Si合金显微组织和硬度的影响

Global Blueprint of Energetic CNPC

China National Petroleum Corporation （CNPC） is taking on the world with great success. The nation＇s top oil producer began energy-exploration projects for the first time in a number of countries last year, such as Equatorial Guinea, Uzbekistan and Argentina. This brings the total number of overseas countries where CNPC has a total of 66 projects in operation to 26, forming five major operational regions including Africa, Central Asia, South America, the Middle East and Asia Pacific. With the overseas oil and gas business brought under rapid development, the newly additional recoverable reserves of the company worldwide reached 65.40 million tons.
