2008 financial crisis, Chinas petrochemical industry has suffered unprecedented situation, the international crude oil prices continue to climb, while oil prices have failed to integrate with the national oil prices, leading to the phenomena of refined oil market upside down historic serious level; 2009 financial crisis Chinas real economy most affected by the year of the new century, Chinas economic development since the worst of the year. Authoritative data show that in 2009 China Oil and Petrochemical Enterprises under the influence of the financial crisis, energy conservation, is facing serious challenges: international oil prices fluctuating, the upstream sector faces great economic uncertainty; domestic oil market, supply exceeds demand, excess of resources, competitive full upgrade, improvement in efficiency is more difficult; chemical market by the industry cycles, especially for some new projects put into operation at home and abroad, the market more competitive and profitable chemicals segment space is squeezed. Moreover, the incremental factors increased significantly, due to the increase in investment depreciation and rising interest rates, outsourcing of raw materials, coal, electricity, steel production and consumption of major materials prices are rising.

: Microsoft TechFest not only have social networks and on the telescope. Microsoft also discussed its roots closer to the new technology: the concept of the operating system called Singularity, it will be the show windows of some of the advanced computer science. The software is not a new version of Windows or "re-heated" DOS. It is an operating system for computer science research prototype. Microsoft Research, Rick, a senior vice president, said in a statement, Singularity is not a new version of Windows. We can see it as a concept car. It is a prototype operating system designed for the operating system and application software interaction mechanisms to be tested. We will provide it to the computer science community, hope that it will enable researchers to more quickly test new ideas.
