6Debris Flow Hazard Assessment Using Set Pair Analysis Models:Take Beichuan County as an Example显示文摘Assessment of debris flow hazards is important for developing measures to mitigate the loss of life and property and to minimize environmental damage. Two modified uncertainty models, Set Pair Analysis(SPA) and modified Set Pair Analysis(mSPA), were suggested to assess the regional debris flow hazard. A case study was conducted in seven towns of the Beichuan county,Sichuan Province, China, to test and compare the application of these two models in debris flow hazard assessment. The results showed that mSPA only can fit for value-variables, but not for non value-variable assessment indexes, Furthermore, as for a given assessment index xi, mSPA only considers two cases,namely, when grade value increases with xi and when grade value decreases with xi. Thus, mSPA can not be used for debris flow hazard assessment but SPA is credible for the assessment because there are no limitations when using SPA model to assess the debris flow hazard. Therefore, in this study SPA is proposed for assessing debris flow hazard.YANG Feng-guang LIANG Yue SINGH Vijay P.

9Novel adaptive Hatch filter to mitigate the effects of ionosphere and multipath on LAAS显示文摘It has been proven that carrier smoothing and differential global positioning system (DGPS) are effective to improve the accuracy of pseudorange by reducing the noise in it and eliminating almost all the common mode errors between the ground station and user. However, another issue coming with local area augmentation system (LAAS) is how to find an adaptive smoothing window width to minimize the error on account of ionosphere delay and multipath. Based on the errors analysis in carrier smoothing process, a novel algorithm is formulated to design adaptive Hatch filter whose smoothing window width flexibly varies with the characteristic of ionosphere delay and multipath in the differential carrier smoothing process. By conducting the simulation in LAAS and after compared with traditional Hatch filers, it reveals that not only the accuracy of differential correction, but also the accuracy and the robustness of positioning results are significantly improved by using the designed adaptive Hatch filter.Lin Zhao, Liang Li, Ming Sun, and Xiaoxu Wang College of Automation, Harbin Engineering University, Harbin 150001, P.

10Roles of ABA Signal Transduction during Higher Plant Seed Development and Germination显示文摘ABA is one of the 5 phytohormones in higher plants, which is also the most important hormone that regulates higher plants in response to environmental stress, by ABA signal transduction. Understanding ABA signal transduction at the molecular level is crucial to biology and ecology, and rational breeding complied with corresponding eco-environmental changes. Great advancements have taken place over the past 10 years by application of the Arabidopsis experimental system. Many components involved in ABA signal transduction have been isolated and identified and a clear overall picture of gene expression and control for this transduction has become an accepted fact. On the basis of the work in our laboratory, in conjunction with the data available at the moment, the authors have attempted to integrate ABA signal transduction pathways into a common one and give some insights into the relationship between ABA signal transduction and other hormone signal transduction pathways, with an emphasis upon the ABA signal transduction during higher plant seed development. A future challenge in this field is that different experimental systems are applied and various receptors and genes need to be characterized through the utilization of microarray chips.Shao Hongbo1,2 * Liang Zongsuo2,3 Shao Mingan2,4 1Bio-information College of Chongqing University of Posts and Telecommunications, Chongqing 400065, P.

11Analysis on Dynamic Heterosis for Allelopathy in Rice Under Different Environment Conditions显示文摘In this study, 5 parental rice varieties with different allelopathic potentials were employed indiallel cross [P(P+ 1)/2] to get a set of genetic materials including parental lines and two generations of F1 s.The dynamic heterosis for allelopathy in rice under different environmental conditions, was analyzed by usingadditive-dominant developmental genetic model. The results indicated that heterosis in both F1 and F2 showedinhibitory effects on shoot and root length of receiver plant (Lactuca sativa L. ). Heterosis over mid-parentbased on population mean(HMP) in F2 was lower than that in differental environmental conditions, showing1/2 HMP in F1. The heterosis in rice allelopathy was much higher under the field environmental conditionswith lower temperature and weaker sunlight than that under favorable environment, implying that the allel-opthic potential could be increased by stress environment. This finding interpreted the genetic reason thatplant could produce more allelochemicals under unfavorable environment.LIN Wen-xiong, DONG Zhang-hang, CHEN Xiang-xu, HE Hua-qin, SHEN Li-hua, GUO Yu-chun, LIANG Yi-yuan, CHEN Fang-yu and LIANG Kang-jing(Fujian Agriculture and Forestry University, Fuzhou 350002 , P.

14Electrocatalysis of Oxygen Evolution Reaction on Ti/SnO_2+RuO_2+MnO_2/MnO_2 Electrode in Sulfuric Acid Solution显示文摘The Ti-Supported MnO2 electrode was modified by introducing SnO2 +RuO2 +MnO2 as an intermediate layer into the Ti/MnO2 interface. The anodic polarization curves were measured at various temperatures ranging from 30 to 80 ℃ and the activation energy for the oxygen evolution reaction was evaluated. The experimental activation energy increased linearly with increasing the overpotential. The activation energy at the equilibrium potential was linearly correlated with the difference between the crystal field stabilization energies of Mn4+ at initial state and Mn4+ at transition state. The electrocatalysis characteristics of the anode were discussed by means of themechanism of the substitution reaction of the ligand(SN 1 and SN2) and molecular orbital theory.The results show that the anode has better electrocatalystic characteristics.LIANG Zhen-hai~(**), FAN Cai-mei and SUN Yan-ping(Laboratory of Electrochemical Engineering Research, College of Chemical Engineering, Taiyuan University of Technology, Taiyuan 030024, P.

15The Effect of Body Pitching on Leg-Spring Behavior in Quadruped Running显示文摘In this paper we investigated how the running speed would affect the dynamics of body pitching, and whether body inertiais important for animals. Passive trotting of spring-mass model and passive bounding of spring-beam model were studied atdifferent speeds for different sets of body parameters respectively. Furthermore, different body inertias were used in bounding.We found that running speed exerts effect on leg performance by means of centrifugal force. The centrifugal force can be understoodas an enhancement to the natural frequency of the spring-mass system. The disadvantage of body pitching may beoffset by the great increase in centrifugal force at high speed. The results also reveal that body mass distribution might not be themain reason for the difference in maximal running speeds of different animals.Qi Deng, Shigang Wang, Qinghua Liang, Jinqiu Mo School of Mechanical Engineering, Shanghai Jiao Tong University, Shanghai 200240 P.

17Modelling Solitary Waves and Its Impact on Coastal Houses with SPH Method显示文摘The interaction between solid structures and free-surface flows is investigated in this study.A Smoothed Particle Hy-drodynamics(SPH)model is used in the investigation and is verified against analytical solutions and experimental obser-vations.The main aim is to examine the effectiveness of a tsunami-resistant house design by predicting the wave loads on it.To achieve this,the solitary wave generation and run-up are studied first.The solitary wave is generated by allowing a heavily weighted block to penetrate into a tank of water at one end,and the near-shore seabed is modelled by an in-clined section with a constant slope.Then,the SPH model is applied to simulate the three-dimensional flows around dif-ferent types of houses under the action of a solitary wave.It has been found that the tsunami-resistant house design re-duces the impact force by a factor of three.LIANG Dong-fang N.

19SIMULATION OF THE CHANGE OF SINTERING NECK BETWEEN TWO GRAINS IN TWO DIMENSIONS显示文摘A modified two-sphere model of sintering neck has been proposed, wherein three diffusion mechanisms including surface diffusion, grain-boundary diffusion and coupled surface and grain-boundary diffusion are assumed. Sintering neck is appropriately simulated using the modified model. The dynamic change of sintering neck is presented using the simulation. The variational shape of sintering neck in surface diffusion mechanism is continuous, whereas in grain-boundary diffusion mechanism, besides the variational shape of sintering neck being continuous, the center distance between the particles is also assumed to contract. However, the variational shape of sintering neck in coupling diffusion mechanism is integrated using the two diffusion mechanisms mentioned above.Y.Y. Zhu, S.H. Liang*, Z.J. Zhan, P. Xiao, and Z.K.
