    Shaking flask experiments were used to study the indigenous microorganisms leaching of heavy metals from sediment in the optimum conditions,which were determined to be pH =3.0,65℃ and 7% pulp density.Residues from the bioleaching were analyzed through XRD and three-stage BCR sequential extraction procedure.Results show that heavy metal(Cd,Mn,Cu,Pb,Zn) contents sharply decrease over 7 days leaching,from 4 530 mg/kg,7 650 mg/kg,830 mg/kg,29 530 mg/kg,62350 mg/kg to 730 mg/kg,1280 mg/kg,390 mg/kg,13 810 mg/kg,15650 mg/kg respectively.Acid extractable percent content decreases remarkably during the bioleaching process;meanwhile,residual form percent content rises obviously.The environmental availability and potential risk of heavy metals are less than the standards listed in Hazardous Waste Distinguishable Standard (GB 5085.3-2007).Indigenous microorganisms can efficiently implement the resources and harmlessness of heavy metals in sediment.

    Based on the characteristics of banking industry in the transformation period in China,the author analyzes how the factors influence the performance of banking industry.Generally,the study  in this paper is based on the review of vested reform path,combining with the facts and drawing the conclusion by deduction.As far as the stabilization and performance of the financial system were concerned,the optimum market structure is oligarch competitive market.That the property right was monopolized by the government is the root of our banking industry’s inefficiency and the motivation of property right reform.To improve the banking industry’s performance,the government should spare no effort to construct an honesty oriented society.
