摘要：
In this study, Immobilized Saccharomyces Cerevisiae (ISC) was prepared through sodium alginate embedding gelatin method after the dry cells had been cross-linked by formaldehyde. The influences of solution pH, initial U(VI) concentration, and contact time on U(VI) biosorption were studied. The optimal U(VI) adsorption conditions was observed at pH 7.0, initial U(VI) concentration 60 mg.L-1 biosorbent dose biosorption equilibrium was established in 1.5h.

摘要：
In the case of in-situ leaching of uranium, the primitive geochemical environment for groundwater is changed since leachant is injected into the water bearing uranium deposit. This increases the concentration of SO_4~(2-), uranium and other heavy metal ions and results in the groundwater contamination. The effects of pH values of the simulated solution on the reduction of SO_4~(2-) and the removal of uranium and other heavy metal ions by sulfate reducing bacteria(SRB) were studied. The results show that, when the pH value of the simulated solution is about 8, the reduction rate of SO_4~(2-) by SRB and the removal rate of uranium, Mn~(2+), Zn~(2+), Pb~(2+) and Fe~(2+) will reach their highest values. A bioremediation technique for remediation of groundwater in in-situ leaching uranium mine can be developed.

摘要：
Because of the uncertainty of the parameters and characteristics of rock joints, this paper performed research in three respects. (1)The contract model of structural planes established by using ABAQUS, and, based on the contract model, the non-linear finite element model for analyzing the stability of rock slope was established. (2) The model between the rock mass mechanics parameters and anti-slide and down-slide forces was built up by using the Adaptive Neuro-Fuzzy Inference System (ANFIS) consisting of artificial neural network and fuzzy logical inference. (3) The program of reliability analysis was compiled by using Monte-Carlo simulation (MCS) and MATLAB, a new reliability analysis method was proposed by coupling ABAQUS, ANFIS and MCS, and the method was used to analyze the reliability of a rock slope. The results show that the contact model of structural planes has great influence on the precise of numerical simulation, that the tangent spring element model could ensure the precision and enhance the convergent efficiency, and that the method could avoid compiling redundant finite element program, reduce the computing time, and improve calculation precision.
