Homemade water in water cationic polyacrylamide (CPAM) emulsion was applied in cigarette paper pulp as dry strengthening agent with other strengthening agent. Good collaborative effect was achieved when CPAM was used in bleached wheat straw pulp with strengthening agent E and with cationic additives L as paper pulp strengthening agent. It was also showed that distinct strengthening effect was obtained when CPAM emulsion was applied in mixture of bleached needle kraft pulp (NBKP) and wheat straw pulp, breaking length and tearing index of cigarette handsheet made of mix pulp was respectively increased by 22.2% and17.0% when the dosage of CPAM was 0.8% of dry fiber. Through analysis of cigarette handsheet section scanning electron microscopy (SEM) photos, strengthening mechanism of CPAM emulsion to cigarette paper pulp was preliminary studied.

New flue-curing process which can accommodate new curing barn which temperature and humidity can be auto-controlled was studied. Based on results of the study on new curing barn and the baking theory, the flue-curing process for new curing barn was programmed. Flue-curing results of this new curing process for new curing barn were compared to the results of conventional baking process for conventional barn. The comparison result was that the new process was simple, convenient and easy-running. The quality of cured tobacco leaf from new curing process was improved: proportion of orange tobacco leaf, the first class tobacco leaf and the first/secondary class leaf was improved by 3.38, 4.74 and 2.03 percentage respectively than the value of conventional process. Meanwhile, the value of total sugar, starch, nicotine, total nitrogen, protein and the difference between total sugar and reducing sugar were lower than the result of conventional process. Chemical composition was more balance than conventional process.

In this paper, the traffic detection system based on ground sense coil is studied. Due to the change of ground sense coil inductance, the output waveform frequence of LC oscillation circuit changes [1]. The LC oscillation circuit is composed by the three point detection circuit. Then the wave is shaped into a square-wave by shaping circuit. The square-wave is transmitted into MCU, the frequency change is detected by MCU and motor is controlled by control signal from the MCU.So when a vehicle passes above the ground sense coil, this approach makes automobile blockader lift the stop lever automatically. And the system can stop the lever falling when there is a vehicle below the lever, so this system can prevent the vehicle damage. This system can improve practical value and application prospect of a automobile blockader.

Based on a wind turbine thick concrete raft foundation for the engineering background, through the adiabatic temperature rise test, the datum of the hydration heat of concrete are obtained; and concrete solidification temperature field numerical simulation and analysis are conducted by finite element analysis software ANSYS; by means of the temperature sensor measurement systems, the foundation concrete pouring process variation of the temperature field is obtained by real-time monitoring. Studies show that: the temperature rise inside the concrete points has the same trend, but the peak and the peak of the age are different. The maximum temperature inside the concrete is mostly shown in the initial 3-5d of concreting; temperature gradient along the thickness direction of the foundation is obvious; massive concrete is significantly affected by the outside temperature.

Against the poor accuracy of the vehicle counters extracted by existing vehicle detection technology, a motion vehicle detection method based on self-adaptive background subtraction with cumulative inter-frame difference is proposed in this paper. Cumulative inter-frame difference is used to subtract binary object mask. According to the binary object mask, in the area of moving objects the pixels of last background are used to modify the current background, otherwise the pixels of current image are used. The result of this operation is the current background. Then the background difference method is used to detect moving vehicles.

Though the auction existed for a long time, the research on the auction theory has been started formally since 1961. One of the prerequisites in auction theory is that all bidders are rational. At present the auction theory hasn’t involved irrational bidders. The paper first introduced the irrational factors into auction theory and analyzed what is the equilibrium of the first-price sealed auction when the values of bidders are uniformly distributed on [0, 1] and some bidders are irrational. This paper also pointed this equilibrium is a trembling-hand perfect equilibrium and discussed the revenue of the seller in this case contrasting the revenue of the seller when bidders are rational. In the end this paper put forward some question on the future research.

Solubility of stearic acid in ethanol, 1-propanol, 2-propanol,l-butanol, acetone, methylene chloride, ethyl acetate and 95% ethanol was experimentally determined by the synthetic method from (293 to 315)K. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The solubility of stearic acid in methylene chloride was found to be the highest, and the value in 95% ethanol was the lowest. Results are correlated by semi-empirical equations, which show a good fit to the experimental data.

An aqueous two-phase system of polyethylene glycol (PEG)/(NH4)2SO4 with the behavior of forming aqueous two-phase and the distribution rules of potassium glycyrrhizinate in the aqueous two-phase system were studied. Effects of the molecular weight of PEG, the mass fraction of PEG and (NH4)2SO4, and pH value were investigated. The result show that when the mass fraction of PEG1000 was 50%, the mass fraction of (NH4)2SO4 was 5.7%, and pH value was 6.5, the highest extraction recovery of potassium glycyrrhizinate could reach 99.7%. This aqueous two-phase extraction may provide a new technique for separation of potassium glycyrrhizinate.

In this work, four oil displacement surfactants (EL110, SG20, Span60 and Tween80) were used to study the extraction of bitumen from oil sands. The effect of concentration of surfactant, extraction temperature, extraction time, the addition of NaOH and extraction solvents was investigated. The results showed that the best concentration of EL110、SG20 and Tween80 were 3%（wt）, 0.1% and 10%，respectively, corresponding to the yield of bitumen were 26.4%，33.4% and 30.7%. The addition of NaOH to EL110 and SG20 solution improved the yield of bitumen, which were 45.9% and 48.0%. With the temperature increasing, the yield of bitumen increased speedily. The extraction time is 2 hours. For Tween80, at 60°C, using ethanol as solvent gave a higher yield of bitumen than that of using water. At 70°C, using pure ethanol as extraction solvent gave the yield of bitumen 93.3%. At 60°C the yield of bitumen using pure ethanol was 68.9%, addition of 0.5% Span60 improved the yield to 96.9%, but the addition of Tween80 had no effect on the yield.

The acicular γ-FeOOH powders were synthesized by liquid-precipitation and air-oxidation method using FeCl2•4H2O as raw material. The affecting factors, which consist of alkaline ratio (OH-/Fe2+), reaction temperature and dropping speed of alkaline, were discussed. From the results, it was shown that when the ratio of OH-/Fe2+ was controlled in the range of 0.6-1.2 in the crystal seeds formation process, the pure phase of γ-FeOOH can be formed. When the ratio of OH-/Fe2+ was lower than 0.6, the γ-FeOOH crystal seeds could not be formed. While the ratio of OH-/Fe2+ was higher than 1.2, the phase of Fe3O4 appeared. According to the principle of chemical kinetics and chemical thermodynamics, the phases of α-FeOOH and Fe3O4 appeared when temperature was higher than 30°C. In the process of the crystal seeds growth, the suitable reaction temperature was at 50°C.

An electro-thermo coupling finite element model is developed to investigate the electromigration and electro-thermo-mechanical effects on electronic packaging. Sn4.0Ag0.6Cu (SAC405) solder ball are commonly used on POP package in this research. Current density arising in the Copper trace above SAC405 solder ball implies the hot spot where results in an electromigration along the current direction. Finite element predictions reveal the peak electro-thermo-mechanical effective stress is located at the regions where electromigration potentially occurred. Current crowding, temperature distribution and electro-thermo induced effective stress distribution are predicted. A submodel scheme is applied for evaluation of equivalent life time of solder ball. Reliability analysis on electro-thermo-mechanical for SAC405 solder ball is evaluated.
