Abstract294)   HTML    PDF (871KB)(158)      
Construction standardization and civilization are not only the minimum requirements of the construction site, but also the innovation of the construction field in the new era, which are related to the social and economic development and the process of national modernization.Based on the recruitment and bidding information of an oil depot and taking four different construction schemes as the basic data, a standardized construction management evaluation index system was firstly constructed. On this basis, the standardized construction scheme evaluation system was constructed by entropy weight method and comprehensive evaluation method. The results show that the degree of standardization and civilization of the four schemes is ranked as M3>M4>M1>M2. The first⁃level index weight ranking is environment>safety>energy saving>cost>quality>progress. Among them, the weight proportion of environment factor is the largest, about 0.193, and the weight proportion of project progress factor is the smallest, about 0.128. Therefore, during the construction of oil depot, the emphasis should be placed on construction environment and safety construction, and the road of green, standardized and sustainable development should be taken.

Guan Lei, Hou Mingzhi, Huo Peng, Wang Ying, Wang Changhe
Abstract426)   HTML    PDF (731KB)(290)      
A mononuclear cobalt complex [Co(H2L)(phen)2(H2O)]·4H2O (H2L2-=4,5⁃dihydroxy⁃1,3⁃disulfonate ion, phen=1,10⁃phenanthroline) was synthesized by hydrothermal method. The composition and structure of the complex were characterized by X ray single crystal diffraction, elemental analysis and thermogravimetric analysis. Single crystal diffraction study shows that the cobalt ion is six⁃coordinated, which can coordinate with the four nitrogen atoms of two phen ligands and the oxygen atoms of water molecule and sulfonate group, forming the twisted octahedral configuration in the complex. Compared with the ligand, the fluorescence emission peak of the complex has a blue shift, and the maximum emission peak is at 380 nm.

Abstract536)   HTML    PDF (1130KB)(178)      
The thin strips of Fe(Co)⁃Hf⁃B⁃Cu iron⁃based strip amorphous alloys were prepared by single⁃roller⁃quenching method. The amorphous structure was determined by XRD, Mössbauer spectroscopy and transmission electron microscopy. The thermal stability of different samples was tested by differential scanning calorimetry. The results indicate the glassy structure of all the samples. Furthermore the results indicate that the thermal stability of amorphous alloys can be increased by faster cooling rate or adding pure B elements. And it can be also identified to improve the thermal stability of amorphous alloys that alloying components with the appropriate amount of Co.

Abstract481)   HTML    PDF (1668KB)(252)      
ZSM⁃5 molecular sieve was used as carrier, cerium (Ce), manganese (Mn), nickel (Ni) and copper (Cu) were used as active components to prepare metal⁃supported catalyst to catalyze ozonation treatment of phenol wastewater. The catalyst was prepared by impregnation method and characterized. The effects of active components, ozone dosage, catalyst concentration and pH on the treatment of phenol wastewater were investigated. The results showed that Ce⁃ZSM⁃5 had the best catalytic effect and COD removal rate under the conditions of pH=7, catalyst concentration of 1.00 g/L, ozone dosage of 44.0 mg/min and reaction time of 60 min. It is 85.74%. When Ce⁃ZSM⁃5 is added, about 80% of the ozone can be saved. It shows good stability which the COD removal ratio reached about 70% after the catalyst repeatedly used for 7 times.

Abstract644)      PDF (1768KB)(422)      

A method for measuring the refractivity of saturated alcohol gas in high precision in closed vessel had been designed. This experimental apparatus used an interference method to observe the variation of interference fringes when the gas pressure changed, combining with the relationship of the number of the changing interference fringes and the refractivity of saturated alcohol gas, then the refractivity of alcohol gas under a certain pressure could be measured. The results showed that this method was accurate in deduce, simple in measurement and method, and reliable. This method could be promoted to measure the refractivity of gas. Especially, it also could be used to measure the liquid level of the liquid-storage tanks.

Niu Hong,Wang Yidan,Wang He
Abstract623)      PDF (1417KB)(478)      
The Lotka-Volterra predator-prey biological model is mainly studied in this paper by introducing the new population which has no ability to prey the other population to form a simple competition between predator and prey when the number of predators is excessive. Based on above condition, differential algebraic biological model is established according to the conservation. Then, the stability of biological model is discussed when the parameters change in a certain range by applying the stability analysis method and the related criteria of differential algebraic system. Finally, the model is the simulated numerically by considering the results of the analysis and using the Matlab software, and the simulation results show that the system has a limit cycle when the parameters vary a certain value, which proved that the complex nonlinear phenomena exist in the differential algebraic biological model.

Abstract620)      PDF (1649KB)(469)      

In order to optimize the transportation pipeline of heavy oil and provide baseline data for the study of energysaving technology, the experimental study on the viscosity-temperature characteristics and rheological properties of heavy oil in Huanxiling was carried out. The viscosity-temperature curve and the rheological characteristic curve were drawn, the viscosity-temperature equations and the rheological equations were fitted, and the viscosity-temperature index was calculated at each temperature interval. Through the viscosity-temperature curve and rheological characteristic curve fitting, the results showed that the correlation coefficient was close to 1 which indicated a higher degree of fitting and the small error. The rheological index was less than 1, which indicated that the heavy oil used in the experiment was pseudo plastic fluid. At the test temperature of 70 ,the heavy oil showed Newtonian behavior.

WANG Yi, ZHAI Chun-yan, LI Shu-chen
Abstract396)      PDF (312KB)(339)      
An algorithm of model reference iterative learning control (MR-ILC) was proposed for nonlinear systems with periodic and non-periodic uncertain disturbances. The objective is to make the state variables of a controlled system can be steered to follow the state variables of a reference model that does not necessarily have the same structure as the controlled system on condition that the controlled system is satisfied with assumptions and adopted with matching learning rate. The λ-norm was adopted as the topological measure in proof of the convergence of the system. The effectiveness of proposed scheme was illustrated by simulation results.

Abstract441)      PDF (206KB)(293)      
A high efficient decalcification agent without phosphorus or metal included was developed for Liaohe crude oil with high calcium content. The calcium contents in the crude oil before and after decalcification were analyzed by atomic absorption spectrometry. Influences of decalcification agent to calcium radio, water injection amount, working temperature, time for sedimentation and reaction were studied. The results show that when the decalcification agent dosage is 0.6, filling water ratio is 10%, reaction temperature is 90 ℃,the time for settlement is 10 h and reacting time is 5 min, the decalcification rate of Liaohe crude can reach more than 90%.
