摘要：
This template is mainly about the analysis of mechanical property of SCC in a flow state in the V-Funnel. It aims to establish the testing formula of rheological constants by Engineering Fluid Mechanics, which can provide academic basis for V-Funnel test of SCC properties. MATLAB image process technique was introduced in the process which can greatly improve its precision and reliability. It can also provide a new train of thought to experimental data.
摘要：
With the example of the water supply engineering planning of small towns in southern china, the effects of town water consumption forecast, water resource selection, water site choice, pipe network planning on the present engineering planning of water supply were investigated. The analyses show that the water consumption forecast should adopt many kinds of methods to check each other, and finally determine a proper value. To ensure water yield of source water reliable and water quality to meet the requirements are the first principle of the water resource selection. The location of water plant should be determined according to the characteristics of the water source and the hydrological and hydrogeological conditions, in accordance with the relevant requirements specification. The basic requirements of the pipe network layout are as follows: the security of water quality; the reliability of the water volume and water pressure; the operation reliability and the least investment. As a part of the overall planning, the water supply engineering planning should proceed from reality to deal with the relationship of the recent construction and long-term development in order to push small towns economy to a rapid growth.

摘要：
Soil around the cylindrical pore is divided into elastic and plastic regions. In the elastic region, the small deformation theory is applied while in the plastic region, the large deformation theory and unified strength criterion are applied. According to the stress equilibrium equation and the boundary condition of continuous stress and deformation, the theoretical solution to plastic region radius, limit expansion pore pressure excess pore pressure and excess pore water pressure of the cylindrical cavity expansion can be derived when considering large deformation and non-drainage problems. Compared to the theoretical results of Cao L.F., the theoretical calculation results are closer to the field test results which show that the theory has a certain value in engineering application. Through calculations and analysis, it is also derived that expansion pore pressure increase is non-linear with the increase of b value, while the excess pore water pressure is just the opposite.

摘要：
Biosorption has been developed as an effective and economic method to treat wastewater containing low concentrations of metal pollutants. In this study, a bacterium, Citrobacter freudii, was used as a biosorbent to adsorb uraniumions. The factors which influence the adsorption of uranium by Citrobacter freudii were investigated, including pH, the strain dosage and the initial concentrate of uranium. The results showed that the adsorption efficiency increased with the increased of pH in the beginning of the adsorption and reached its maximum at pH 6; when the strain dosage and the initial concentrate of uranium were 6.0g/L and 20mg/L, respectively, the adsorption efficiency reached 93.89% and 94.68%, respectively. The authors investigated the active sites of bacteria for biosorption and the results proved that carboxyl in the cell wall played an important role in biosorption.
摘要：
Different adsorptive mediums and adsorbents’ compounds were chosen to remove arsenic from Yangzonghai Lake wastewater. Results showed that Ca(OH)2, attapulgite, bentonite, LDHs these adsorptive mediums had adsorptive capacities of less than 2.5 mg/g of As removal and it took long time for sediment before monitoring; adsorbents compounds’ results showed Fe2O3 and quartz sands had best removal rate and quartz sands had little removal of arsenic. Both strong anion resin and hydrated ferrous oxide-loaded on polystyrene diethanolamine resin(designated as PDR-HFO) can decrease As concentration to less than 0.01 mg/L reaching national standards for arsenic; anions such as SO42- can not be removed when strong anion resin was regenerated causing its loss of exchange ions; PDR-HFO exhibited excellent adsorptive properties and recyclability.

摘要：
Heating energy consumption of rural buildings in China was analyzed in this paper. Thermal insulations were compared between some kinds of biomass and fossil materials. Application forms of biomass materials were discussed for heat insulation in rural buildings, and the potential was analyzed for energy-saving and CO2-emission-reducing. As a big agricultural country, the benefit and potential of biomass materials may be remarkable in heat insulation in rural buildings in the light of local conditions.

CNC Vertical Boring-milling Machine;Rigidity of Principal Axis;Structure Improvement
摘要：
The rigidity of the principal axis of a CNC vertical boring-milling machine was analyzed, and the belt tension and end deformation were also calculated. A project was proposed to improve the structure of the principal axis for finish machining. After the discharge belt pulley was applied on the principal axis, the force transmission and the rigidity of principal axle system were improved considerably. The design and process means were proposed for the three added parts of the improved structure. The improved structure is simplified, secure and low-cost. The machining precision was increased, and the fixing was also become convenient.

摘要：
The effect of masss of natural diatomite, initial dye concentrations, pH and temperature on adsorption was investigated. The adsorption of reactive dye was slightly increased then decreased with rising amouts of natural diatomite that is increasing competition of natural diatomite. The removal rate of reactive black increase with the temperature because of endothermic reaction. The removal rates of reactive black from solution were decreased as the pH increase and gain the maximum in low pH. The removal rate for all concentrations were rapid at initial stages and then keep increase gradually until the progress until equilibrium reached.

摘要：
Solidified dredged materials as environment-friendly materials in construction domain are increasingly popular because of their better mechanical performance and low pollution. Based on the physical characteristic of dredged marine sediments, a series of tests, such as unconfined compressive strength test and tensile strength test, were performed to explore the mechanical properties of cement/lime-fly ash treated sediments for the beneficial use in road construction. Finally, the reinforcement mechanism of solidified sediments was explored by SEM tests from the point of view of the formation of CSH phases and the change in microstructure.

摘要：
<jats:p>In order to research on the inhibition of Cu<jats:sup>2+</jats:sup>to removal of U(Ⅵ) by sulfate reducing bacteria(SRB), the experiment investigated the removal of U(Ⅵ) by SRB through H<jats:sub>2</jats:sub>S reduction process, elecrton transfer process and adsorption process respectively. The results showed that the electron transfer was the main process in removing of U(Ⅵ) by SRB, It accounted for 80% of the total removal. Extracellular polymeric substances (EPS) adsorption of U(Ⅵ) had little effect. When the concentration of Cu<jats:sup>2+</jats:sup>was 5mg/L, Cu<jats:sup>2+</jats:sup>had little effect on the removal U(Ⅵ) by SRB; It inhibited the removal of U(Ⅵ) significantly when the concentration was 15mg/L because of the competition of H<jats:sub>2</jats:sub>S and the electronics of lactic acid between Cu<jats:sup>2+</jats:sup>and U(Ⅵ); When the concentration of Cu<jats:sup>2+</jats:sup>exceeded 25mg/L, it would damage the integrity of SRB’s membrane and the removal of U(Ⅵ) was completely inhibited.</jats:p>

摘要：
The numerical simulation of indoor airflow and poison gas diffusion and transport process is given for different air systems of air-conditioning in large space buildings in this paper. The numerical results show that the poison gas diffusion is affected by indoor airflow, and the variety air systems make the characteristics of poison gas diffusion differently. After arriving at the air return, the poison gas will soon be sprayed from the air inlet of the air system to the whole space which is serviced by the air system.
