The key users of traditional accounting data are the investors, financiers and creditors of the enterprise; while the important customers of accounting data in green economy is the related departments of national and local authorities, especially the management department of environmental protection.
The format and content of financial statements should be reformed, financial statements and reports that reflect the information of green economy should be added, for example, table of return from environmental protection, report of environment responsibility or report of substitute for toxic materials. the disclosure of data of developing green economy, especially the information about environmental resources and environmental protection, will make enterprise that performs good green behavior obtain good image in public and community, and gain good market returns in capital market and product market.

So viscosity is a key parameter to oil performance[2,3].
Added value of acid number Variation of acid number reflects oxidization conditions of base oil and degradation conditions of alkaline additives, in the high temperature conditions, acid oxide generated from the fuel burning and acid material originated from oil oxidization keep rising which increases the acid number constantly [4].
Rising acid number would decline oil performance and induce metal material corrosion, specially bush corrosion.
