Abstract:The recycled aggregate concrete(RAC) were respectively prepared with 0%,30%,50% of recycled aggregate made from C25 grade waste concrete,to research the effect of the recycled aggregate replacement ratio and the load on the corrosion resistance.Then the dry-wet test with the aggressive medium of artificial seawater under the effect of bending stress by 0,10,20,30,40 and 50 cycles were carried out on the RAC specimens to observe the influence of artificial seawater corrosion on the RAC internal damage.The results show that the bending stress has accelerated deterioration velocity of the material performance of RAC in environment of artificial seawater.Furthermore,the corrosion damage of RAC in artificial seawater decreases with the increase of recycled aggregate replacement ratio in the same bending stress coefficient,and the corrosion damage of RAC in artificial seawater increases with the increase of bending stress coefficient in the same recycled aggregate replacement ratio.

Abstract:The design process of structure optimization was discussed with an example of a diagonal square pyramid space grids simply supported at its perimeter. The grid structure height and member cross section dimensions of space truss were taken as the discrete variable variables.The total weight of space truss was considered as the objective function.The restrain condition such as strength,stability,stiffness and the structural deformation were considered.The one-dimensional search method and the modified stress ratio method are adopted as the optimization method and draw up optimization of the space truss structure making up with ANSYS Parameter Design Language(APDL).The calculated results showed that the weight of space truss reduced by 14.1%.Thus the optimum design can obtain a better optimal result and simple for use.

Abstract:In solving displacement of non-uniform beams,all of the textbooks and documents about mechanics of materials expatiate upon uniform beams,whose flexural rigidity EI is constants,while seldom about non-uniform beams.But non-uniform beams whose flexural rigidity EI is variable quantity,are very popular in the practical engineering.When we calculate for rigidity of the non-uniform beams,we achieve firstly equations of deflection curve by making use of various methods.Then obtain the maximum displacement through solving equations.Finally we check the rigidity of non-uniform beams and make it to be safety and reliability.Methods of unit force,integration and the least potential principle is put forward for solving displacement of non-uniform beams.These methods are proved to be correct by instances and be valuable for the engineering practice and theoretical research.

Abstract:The removal of water pollutants and the pollution of membrane were observed by advanced treatment of ultra filtration(UF) and inline coagu-flocculation-UF(ICUF) with different amount of coagulant and slightly polluted water as raw water.It was shown that the effluent quality of combination process,with its turbidity below 0.1 NTU and the CODMn average removal rate 33%,was better than UF's after 150h operation.It was also shown that the inline coagu-flocculation could retard membrane pollution since the growth of transmembrane pressure in ICUF was more slowly than UF's and the membrane pollution in ICUF could be removed.The UF effect would be improved with the amount of coagulant increased,but if the costs were considered,the optimal coagulant dosage was 30 mg/L.

Abstract:The Gumbel Copula functions and Clayton Copula function of the Archimedean-Copula Functions were selected for the Kendall correlation analysis based on the data of Central parity rate of RMB exchange rate against yen,dollar and euro respectively from July 25,2005 to April 15,2010.And the log-daily returns of the U.S.dollar,the euro and the Japanese yen against the RMB were contrasted by the index of tail dependence.The results show that the U.S.dollar against the RMB exchange rate has a negative correlation with the euro and the yen,while the euro positive correlation with the yen.Therefore,if the exchange rate policy of the U.S.dollar against the RMB turns to the direction of RMB appreciation in the environment that U.S.government puts pressure on the RMB exchange rate,the interests of European Union and Japan will decrease.

Abstract:Multiple analysis methods including general slice and casting slice scan electron microscope,etc,were adopted to study the diagenesis of the 8th member of Shihezi Formation sandstone of the study area and its effects on physical properties.The result shows that Lithic quartz sandstone is the main sandstone type,with less or low composition feldspar;compaction is one of the main causes for porosity losses,and the primary porosity loses further under cementation which is also the main cause of this compact sandstone,especially,carbonate,secondly,quartz increasing margin and kaolinite,but cementation of chlorite film can restrain compaction and is beneficial to preserve primary porosity.Physical properties of sandstone reservoirs can be improved by dissolution,during the later period of diagenesis.Diagenesis reaches A-B period,porosity developed by dissolution is one of the main porosity-type of this period,where it is developed well is the favorable reservoirs area.

Abstract:In low accommodation and shallow-shelf settings,spatial variations in accommodation commonly result in the formation of remnants ranging in size from small(few to tens of square kilometers) to basin scale(hundreds of square kilometers).Remnants of porous and permeable facies encased in low-permeability facies are an important and relatively common type of stratigraphic trap.In foreland basins,remnants may be more common in distal than proximal settings;in ramp-margin settings,depositional remnants appear to be closely associated with lowstand to transgressive systems tract deposits.To identify depositional remnants,the first step is the identification of regionally extensive erosion surfaces;then,the key to remnant identification lies in the detailed correlation of both overlying and underlying time-stratigraphic units.Depositional remnants are used to illustrate their significance to petroleum exploration and production;recognition and integration of the depositional remnant concept into stratigraphic studies may lead to new exploration plays in mature hydrocarbon producing basins.

Abstract:Damage of speed sensitivity during water injection process exists in the Xinganling Group because of the high clay content and loose stratigraphic framework.According to the speed sensitivity experiment and the production parameters,this paper has calculated the damage radiuses and the optimal acidizing radiuses of conventional injection well and fractured injection well through theoretical derivation.This technology has been applied on 7 wells in field test.Speed sensitivity experiment shows that Xinganling Group shows m-strong to strong speed sensitivity.The damage radiuses of Ⅰ～Ⅳ layers of conventional injection well are 2.42m,0.94m,1.30m and 0.26m respectively,damage of fractured injection well is only exist in I layer and the damage radius is 3.3m.Theoretical derivation shows that the optimal acidizing radiuses of Ⅰ～Ⅳ layers of conventional injection well and I layer of fractured injection well are 2.4m,1.6m,1.6m, 1.8m and 3.3m respectively.Field test in 7 wells has confirmed that this method has strong practical applicability and can be used to the acidizing design of other sandstone oilfield.
