环境科学 , 2012,
Abstract: 采用共沉淀法制备了Zn/Cr摩尔比为1∶1~5∶1的Zn/Cr型阴离子黏土(Zn/Cr-LDHs),选取2∶1 Zn/Cr-LDHs分别在300、400、500℃条件下放入马弗炉中煅烧2 h,制备了煅烧阴离子黏土(Zn/Cr-LDO).采用X射线衍射光谱(XRD)、傅里叶红外光谱(FTIR)、原子吸收法(ASS)、比表面积测试法(BET)对上述制备的材料结构形态进行表征.研究2∶1 Zn/Cr-LDHs和Zn/Cr-LDO在紫外和避光条件下对活性艳橙X-GN的去除.实验表明,2∶1 Zn/Cr-LDHs的吸附效果不受紫外光照射的影响,煅烧后形成的Zn/Cr-LDO在紫外光的照射下,对活性艳橙X-GN的去除率是避光条件下的2倍,说明煅烧后的Zn/Cr阴离子黏土具有光催化性能,Zn/Cr-LDO对活性艳橙X-GN的去除是吸附和光催化的共同作用.

Ru-Gui Wang,Gan-Wei Cai,Xiao-Rong Zhou
Mathematical Problems in Engineering , 2011, DOI: 10.1155/2011/254547
Abstract: The 2-DOF controllable close-chain linkage mechanism is investigated in this paper. Based on the characteristics of the multi-DOF nonlinear coupling dynamic equation of the system established by the finite element method, an analytic method of multiple-scales Newmark is presented after thinking about the method of perturbation and the method of numerical analysis. Firstly, the first-order approximate solution of the dynamic responses of the system at the time of is calculated by the multiple scales method. Then, taken the first-order approximate solution as the initialization of the generalized coordinate of the system, the stable dynamic response of the system is obtained by the implicit Newmark method. The simulation and experimental results are given in the end. The studies indicate that the method of multiple-scales Newmark is correct and practicable to study the dynamic characteristics of such kind of multi-DOF nonlinear coupling system.

Abstract: the genetic diversity and phylogenetic relationships in the genus secale l. (rye) was evaluated using 24 secale cereale microsatellite (scm) markers. the average polymorphism information content (pic) value of each microsatellite locus in 30 secale accessions evaluated was higher than that in 47 cultivated ryes (secale cereale ssp. cereale). the mean genetic similarity (gs) index in secale was lower than that in cultivated rye. the highest within-species gs index was observed for s. sylvestre and the lowest for s. strictum, whereas the highest between-species gs index was found between s. cereale and s. vavilovii and the lowest between s. sylvestre and s. cereale. there was no obvious difference in gs levels in the cultivated rye accessions from asia, europe, north america or south america. cluster analysis indicated that all the secale accessions could be distinguished by the 24 microsatellite loci. we also found that the s. sylvestre accessions were obviously divergent from the accessions of other species and that the s. vavilovii accessions were closely related to the s. cereale accessions. our results also showed that s. strictum was heterogeneous and showed great within-species differences. the microsatellite-derived dendrogram faithfully reflected the phylogenetic relationships between secale species but did not indicate a possible domestication process of the cultivated rye based on the geographical sources of the accessions.

Abstract: In the title compound, C15H13ClN2O, the molecule displays a trans conformation with respect to the C=N bond. The two aromatic rings form a dihedral angle of 12.0 (3)°. In the crystal, molecules are connected via N—H...O hydrogen bonds into chains propagating along the c-axis direction.
Web Information Extraction for Question and Answering System about Prices of Chinese Agricultural Products
Wen-Sheng Wang,Li Liu,Qing-Tian Zeng,Xiao-Rong Yang
Journal of Applied Sciences , 2009,
Abstract: This study presents an approach to Web information extraction for the question and answering system about prices of Chinese agricultural products. This approach first uses the training corpus to product keyword dictionary and then matches the sample pages to find key information path to format automatic information extraction. The advantage of this approach is effectively to avoid the nonstandard Hyper Text Marked Language (HTML) pages and to obtain high extraction accuracy in specific domain.
Enhancement of singly and multiply strangeness in p-Pb and Pb-Pb collisions at 158A GeV/c
Sa Ben-Hao,Wang Xiao-Rong,Tai An,Zhou Dai-Cui,Cai Xu
Physics , 1999, DOI: 10.1103/PhysRevC.60.047901
Abstract: The idea that the reduction of the strange quark suppression in string fragmentation leads to the enhancement of strange particle yield in nucleus-nucleus collisions is applied to study the singly and multiply strange particle production in p-Pb and Pb-Pb collisions at 158A GeV/c. In this mechanism the strange quark suppression factor is related to the effective string tension, which increases in turn with the increase of the energy, of the centrality and of the mass of colliding system. The WA97 observation that the strange particle enhancement increases with the increasing of centrality and of strange quark content in multiply strange particles in Pb-Pb collisions with respect to p-Pb collisions was accounted reasonably.

Abstract: Objective: To explore the relationship between the portal hemodynamics or the indices of liver fibrosis and the liver function score in patients with different traditional Chinese medical syndromes of liver cirrhosis. Methods: One hundred and forty-seven cases of liver cirrhosis with different syndromes were included in the study. Diameters and blood flow velocities of the portal vein and splenic vein were tested by color Doppler sonarography. The indices of liver function (TBIL, ALT, AST, Alb, Glb, PTA) and the indices of hepatic fibrosis(HA, PC-Ⅲ, LN, Ⅵ-C)were tested. Results: The diameters of portal vein in liver cirrhosis patients with different syndromes (internal accumulation of damp-heat, stagnation of liver-qi, superabundance of dampness due to spleen-asthenia, asthenia of liver and kidney yin, asthenia of spleen and kidney yang, blood stasis) were not significantly different. The blood flow velocities and flow volumes of portal vein in patients with the blood stasis syndrome and the internal accumulation of damp-heat syndrome were significantly different (P<0.05). The diameter of splenic vein in patients with the internal accumulation of damp-heat syndrome was significantly different to that of the asthenia of liver and kidney yin syndrome, or the blood stasis syndrome, or the asthenia of spleen and kidney yang syndrome, respectively (P<0.05 or P<0.01). The blood flow velocity of splenic vein in patients with the blood stasis syndrome or the asthenia of spleen and kidney yang syndrome was significantly different to that of the internal accumulation of damp-heat syndrome, or the stagnation of liver-qi syndrome, or the asthenia of liver and kidney yin syndrome, respectively (P<0.01). The blood flow volume of splenic vein in patients with the internal accumulation of damp-heat syndrome was significantly different to that of the asthenia of liver and kidney yin syndrome, or the asthenia of spleen and kidney yang syndrome, or the blood stasis syndrome, respectively (P<0.01). The liver cirrhosis indices HA and PC-Ш in patients with the asthenia of liver and kidney yin syndrome were significantly different to those of the internal accumulation of damp-heat syndrome (P<0.05). In Child-Pugh classification, the incidence of Child-Pugh C was the highest in the asthenia of spleen and kidney yang syndrome, while the incidence of Child-Pugh A was the highest in the stagnation of liver-qi syndrome. Conclusion: The changes of portal vein dynamics in liver cirrhosis patients with the asthenia of liver and kidney yin syndrome, or the asthenia of spleen and kidne

Journal of Molecular Genetics , 2013,
Abstract: In this study, the genetic diversity and relationship of 18 bramble cultivars and 8 materials from Rubus coreanus were analyzed by RAPD markers. Of the 85 random primers screened, 20 primers gave reproducible and polymorphic bands. Total 251 bands were generated by using 20 RAPD primers, of which 235 (93.6%) were polymorphic. The average number of bands generated per primer was 12.5 with a range from 5-25. The results showed that the genetic distance between Coreanus 3 and 4, both collected in Xichong County, Sichuan Province, was the nearest, while the genetic distance between yellow raspberry Kiwigold and blackberry Olallie was the farthest. The dendrogram of cluster analysis showed that raspberry cultivars and R. coreanus had close genetic relationship, since they clustered into a group. Black raspberry Bristol and blackberry cultivars clustered into another group. The genetic relationships and diversity within the cultivars or materials from R. coreanus was complex, for they didn t cluster together according to their fruit color or original place.
