Science & Technology Review. 2014, 32 (36): 48-51. ;  doi: 10.3981/j.issn.1000-7857.2014.36.007
Full text: HTML (1 KB)  PDF  (538 KB)  ( 90 )
Abstract ( 123 )
Extension set studies the degree and its change of some characteristic that one thing owns from the point of transformation, and describes them by using dependent functions. So, the dependent function is the core of the extension set and an important theoretic foundation of extenics. We summarize the current results of one-dimensional functions and unify the simple and elementary dependent functions. On the basis of the definitions of both distance and side-distance between the point and all kinds of intervals and position value between the point and various types of nested intervals, we propose the basic formulas and properties of generaldependent functions. The results can further deepen the contents of one-dimensional dependent functions and provide theoretical basics for the study on the multi-dimensional ones.

Abstract ( 384 )
The maize starch synthesis ZmSSIIa elongates amylopectin chains from degree of polymerization 6-10 to degree of polymerization 12-25 in the pathway of starch biosynthesis, and plays important roles in kernel yield and quality. The analysis of sequence polymorphism of maize ZmSSIIa gene will provide information for further detection of beneficial mutants associated with yield and quality. In order to reveal the sequence polymorphism of the maize ZmSSIIa gene, a total of 4836 bp sequence of this locus is captured in 86 elite maize inbred lines through a NimbleGensequence capture array. Analysis of the sequence polymorphism reveals that there are 78 SNPs and 19 Indels in this locus. The coding sequences of the maize ZmSSIIa gene contain 24 SNPs, which divide the coding regions into 9 haploytpes, and 7 different ZmSSIIa proteins are encoded by the tested inbred lines. At least 8 recombination events are found to contribute to the haplotype diversity and linkage disequilibrium between polymorphic sites in the maize ZmSSIIa gene. According to the results of the test of neutral evolution, there is no evidence of artificial selection for this gene in the tested inbred lines.

Science & Technology Review. 2014, 32 (36): 69-74. ;  doi: 10.3981/j.issn.1000-7857.2014.36.011
Full text: HTML (1 KB)  PDF  (1077 KB)  ( 114 )
Abstract ( 230 )
Suspended particles in injected water can seriously plug the reservoir, which makes it hard for the water to be injected and the oil to be produced. In order to solve this problem, the plugging of a reservoir caused by suspended particles should be studied. In this paper, a core plugging experiment is designed, where 3 sizes and 5 concentrations of suspended particles are considered. The ratio of the diameter of the suspended particle to the throat diameter is defined as the compatibility. The ratio of the effluent concentration to the injection concentration is defined as the relative concentration. It is shown that when the throat diameter of the core is 0.94 μm and the water permeability of the core is 0.137~0.235×10-3 μm2, the permeability decreases and the plugging occurs after suspended particles are injected. When the particle compatibility<0.777, the relative concentration>0, a part of suspended particles can go through the core, the form of plugging is penetrable; when the particle compatibility>0.777, the relative concentration is 0, the suspended particles can not go through the core, the form of plugging is a shallow plugging; The particle compatibility 0.777 is the critical value from penetrable plugging to shallow plugging. Under an appropriate particle compatibility value, the pore volume and the plugging degree have a good linear relationship. It is suggested that the concentration should be low, the particle size should be in a limited range and the particle compatibility should be far below the critical value.

Abstract ( 349 )
The inner morphological structure of large pore paths is different from neither porous media nor pipes, thus the fluid flow mechanism in them is different from seepage flow and pipe flow. This paper aims to study the law governing fluid flow in large pore paths in unconsolidated sandstone reservoir. The similar number of the physical models of large pore path fluid flow was established based on dimensional analysis. Nine physical models were established with different mesh numbers of sand grains to investigate the relationship between differential pressure and flow rate in large pore paths under different extruding conditions of walls. The results show that the pressure gradient of flow resistance in the nine psychical models increased with the increasing of flow rate, and the higher the extruding degree of the wall, the larger the amplification of the pressure gradient. When the flow rate was increased to a certain value, the fluid flow changed from linear to nonlinear. Fluid flow in large pore paths, porous media and pipes was compared under the same cross-sectional area and same flow cross-sectional area, and the pressure gradient in large pore paths was lower than that of seepage flow but higher than that of pipe flow.

Science & Technology Review. 2014, 32 (36): 80-85. ;  doi: 10.3981/j.issn.1000-7857.2014.36.013
Full text: HTML (1 KB)  PDF  (5434 KB)  ( 321 )
Abstract ( 728 )
In this study, a high-temperature and high-pressure microscopic visualization model was used to simulate water flooding, CO2 flooding and water-alternating-gas (WAG) flooding using CO2 at 60℃ and 18 MPa in complex reservoirs. Multiphase fluid displacement features in porous media were described in detail by observing the multi-phase fluid flow and residual oil distribution in the process of water flooding, CO2 flooding and WAG flooding. The residual oil ratio at each process was quantitatively analyzed using image processing technology and software analysis. The experimental results show that WAG flooding not only decreased fluid slipstream in water flooding, but also reduced gas breakthrough along the high permeability pore in CO2 flooding. WAG flooding made the advantages of water flooding and CO2 flooding complementary to each other, increasing the oil recovery by 12.31% compared with CO2 flooding.

Vertical Uplift Capacity of Combined Cable-slab Foundation in Loess and Influencing Factors

FAN Xuefeng, LONG Zhe, YAN Zhixin
Science & Technology Review. 2014, 32 (36): 86-92. ;  doi: 10.3981/j.issn.1000-7857.2014.36.014
Full text: HTML (1 KB)  PDF  (5061 KB)  ( 461 )
Abstract ( 206 )
Based on the assumption that loess is an elastic-perfectly plastic material which obeys Mohr-Coulomb yield condition and the anchor plate is a rigid body, a three-dimensional numerical analysis model is established by use of the finite-difference software FLAC3D and the anchor-soil interaction is then simulated. The deformation mechanism of loess around plate anchors during uplifting is analyzed by the contact plane element. The influencing factors including depth ratio, loess shear strength parameter, shape and size of anchor plate are considered in the ultimate pull-out capacity analysis. It is found that the ultimate pull-out capacity of anchor plate is jointly influenced by these factors. It increases with the increased depth ratio and loess shear strength, however the influencing extent is different. Expanding the plate size can increase the total capacity, but the capacity per unit area will decrease. For plates of same area, the circular one has the biggest ultimate pull-out capacity while the square takes the second. The coefficient of a rectangle plate decreases when the length-width ratio increases. The rules revealed by this study have a reference value for the study and promotion of combined cable-slab foundation in loess areas.

Science & Technology Review. 2014, 32 (36): 93-97. ;  doi: 10.3981/j.issn.1000-7857.2014.36.015
Full text: HTML (1 KB)  PDF  (1761 KB)  ( 416 )
Abstract ( 332 )
In the several codes and standard equations for the punching shear strength of reinforced concrete slabs, the cover thickness is not an influencing factor of the punching shear strength. 16 specimens of reinforced concrete slabs with various cover thicknesses are selected in the tests. The punching shear strength is found to increase with the increase of the cover thickness, in a nolinear way. The mechanism of the impact of the cover thickness on the concrete slab strength is analyzed based on a comparison between the calculation results and the test results, and finally, a new calculation method is proposed through the evaluation of the incipient theoretical equation. Test data are compared with the provisions of CCES, and with the proposed equation of Matsui, a simplified equation is proposed, which enjoys a better accuracy.

Abstract ( 202 )
In this paper, a pattern classification privacy preservation algorithm is proposed based on the Parzen window kernel density estimation on large scale dataset. Firstly, the probability density is estimated through the original large scale training set. Then the replacement training samples are constructed by the estimated probability. Finally, the replacement training samples are published for the pattern classification training. Thus the privacy on the original training set can be protected effectively. The simulation experiments on Adult datasets fully verify the effectiveness of the proposed algorithm.

Abstract ( 220 )
By taking full advantage of the characteristics of mobile search and government website, a log mining and customization system, which makes use of the advantages of Hadoop in large data processing, is designed and developed. First, it uses Flume and HDFS to realize the collection and storage of massive log and to provide source data and program interface of log mining. Second, the system uses MapReduce to efficiently analyze the log by taking advantage of labels and navigation bar of search result pages. Thus, the vector space model of search result pages and user interest model are established. Third, based on user interest model and combined with MapReduce again, the K-means algorithm which is for cluster analysis is used. Then, users are divided into different interest groups depending on their interests. Finally, by calculating the distance between search result page and the user's interest group, whether the user is interested in this page is determined, then the system adjusts the order of search results and pushes a new page to this user accordingly. Therefore, the personalized search and push function are implemented.
