Abstract ( 196 )
On April 20, 2013, a strong earthquake of Ms7.0 occurred at Lushan County, Sichuan Province of China. The earthquake triggered many landslides and some of the landslides resulted in serious hazards. In this paper, six earthquake-triggered landside impact factors, including the peak ground acceleration (PGA), the elevation, the slope angle; the slope aspect, the slope curvature, and the strata and lithology were selected for a GIS-based quick landslide susceptibility evaluation for the Lushan earthquake. The weights of the six factors and the landslide susceptibility ranks of each factor were assigned in an ordinal rating from 0 to 9 based on the expert knowledge and the information from my previous studies of the 2008 Wenchuan earthquake-triggered landslides. Then, the landslide susceptibility indexes of each grid were calculated and the landslide susceptibility index map of the study area was produced, which was validated based on 3878 landslides triggered by the Lushan earthquake with a success rate of the index map over 75%. This indicates that the method of the quick landslide susceptibility evaluation is reasonable and the result is useful. Finally, based on the landslide susceptibility index values, the study area was divided into five classes, namely the very low susceptibility, the low susceptibility, the moderate susceptibility, the high susceptibility, and the very high susceptibility, and the landslide susceptibility map was produced.

Abstract ( 216 )
Because the Steel Tube Confined Concrete (STCC) supports are built by pouring with concrete in the roadway, and the pouring hole is required on the steel tube of the STCC supports as openings, and should be reinforced. Combining the local opening reinforcement methods with the field production experience, three reinforcement measures are proposed as the pouring short tube, the sealing plug, and the strengthening plate, together with their parameters. By the area replacement method, the three reinforcement measures are shown to meet the grouting requirements in the roadway, as well as to ensure the reinforcement effect. By the axial compression test of STCC short columns and the pouring hole on STCC short columns, the reinforcing effect of the designed reinforced measures and some reinforcement parameters on the mechanical properties of the short column of grouting holes are analyzed. It is shown that the deformation and the load on the grouting hole short column are close to those of STCC short columns by the axial compression test, with the thickness increase of the sealing plug and the strengthening plate, the tested ultimate load on the grouting hole short column is slightly increased, which meet the requirements of the short column reinforcement. From the considerations of the constant strength requirements and the production cost of STCC supports, the thickness of the sealing plug and the strengthening plate are determined as 25mm and 8mm.

Abstract ( 209 )
In order to predict the difficulty degree on filling pipeline blocking of filling system in deep mine, the comprehensive evaluation model of filling pipeline blocking was established on the basis of fuzzy mathematics and the entropy theory. Ten evaluation indexes, such as volume concentration of filling slurry and shape of filling aggregate, were selected as the discriminant ones of the fuzzy synthetic judge model. The corresponding membership matrix was established according to in-situ data of mine and three evaluation standard of filling pipeline blocking risk. The entropy theory was used to calculate the weight of each discriminated index, and the predictive value of filling pipeline blocking was finally achieved and sorted using the rules of fuzzy synthetic judge model. Regarding Longshou mine of Jinchuan Company, Dahongshan copper mine, Hedong gold mine and Xincheng gold mine as evaluation objects of filling pipeline blocking risk, the result shows that the risk grade of Longshou mine of Jinchuan company is a little more than level II, the risk grade of Xincheng gold mine is a little more than level III, the risk grades of Hedong gold mine and Dahongshan copper mine are both less than the level III. The comprehensive evaluation model based on fuzzy mathematics and the entropy theory can reflect the distance between the sample and the evaluation standard, and the evaluation result is objective and reasonable, which has good practicability.

Abstract ( 206 )
The spectrum analysis can be carried out via establishing the detector response function(DRF), to improve the automation level and the computation accuracy of the spectrum data processing. A general DRF model is established for Si-PIN detectors via the analysis of the X-ray physical detect procedure. The model contains four parts: a flat continuum shift from zero to full energy; a Gaussian shaped principal component of full energy peak; a Gaussian shaped Si escape peak; and an exponential tail on the low energy side of the full energy peak. Each part of the model, with a simple format, has a clear and definite physical meaning. Parameters are obtained by using the program, based on the Weighted Least-Squares(WLS) method. Nineteen elements' X-ray spectra in total are fitted in the study, and the fitting reduced chi-squares are also obtained simultaneously, which is in the range of 1.05-2.71. It is shown that this DRF model can represent the characteristic X-ray spectrum peak shape very well.

Abstract ( 181 )
Contraflow operation is an important measure in the emergency traffic evacuation. Based on the theory of the cell transmission model (CTM), a contraflow operation model is built with the total travel time as the objective function. With the numerical solution and the microscopic traffic simulation methods combined, the contraflow operation model is solved numerically with MathProg language and Lp_solve solver, the evacuation process is simulated microscopically using the microscopic traffic simulation software VISSIM. The numerical results and the simulation results are compared to make the model closer to the actual situation. The results show that the contraflow operation can significantly improve the road network capacity and the evacuation efficiency.

Abstract ( 216 )
Icing on blades will seriously affect helicopter's performance, and even result in accidents endangering the safety. Icing Spray Rig(ISR) for helicopter rotor blade is a simulation system used in the test of main rotator and tail rotator of helicopter, which can artificially build cloud conditions for the icing, anti-icing and deicing tests at natural low temperature. This paper presents the components of an ISR and the corresponding principle, and analyzes the critical techniques within the rig design and applications. As a case study, an ISR is designed for the tail rotor test of a certain type of helicopter. For the design, the parameter of the system are ascertained, and the equipments and configures are determined. Based on the calibration on liquid water content and cloud particle diameter, the spray parameters adopted in course of the test are obtained. The test and the result analysis were carried out. Air atomizing nozzles were used to make fog, and it was found that 40 nozzles in 5 rows are reasonable, and the spray density and the flow distance of the cloud particles can meet the requirements of the test. The system can optimize the spray scheme effectively, and the liquid water content and the cloud particle diameter can be controlled by adjusting the water pressure (0.2-0.4 MPa), the air pressure (0.3-0.4 MPa) and the quantities of the operative nozzles (6-18). It is concluded that the experimental results are favorable. The system can work as a good reference for the future development of a large scale ISR and similar tests.

Abstract ( 368 )
To get the vertical roller mill radial stress nephogram, deformation displacement and safety coefficient, and provide a scientific and solution basis for designing key parts of the roll grinding machine transmission device. Based on the structure, working principle as well as force analysis of vertical roller mill, the finite element analysis of rocker arms is carried out on ANSYS Workbench platform by using the CAE technology. First of all, the structure of rocker arms and grinding roll components are simplified, then the three-dimensional entity model and meshing model of vertical roller mill both are established, and then meshed. Secondly, the material attribute, contact type, load and constraints of rocker arms and grinding roll components are defined, and the total deformation, equivalent stress and safety factor of rocker arms are obtained by numerical calculation. Results show that, the maximum displacement of the up rocker arm is 1.1 mm, and the maximal displacement of lower rocker arm is 6.61 mm. The rotating radii are the largest both on the top of the up rocker arm and under the bottom of lower rocker arm, and stress are bigger in these two places. The minimum safety factor of the up rocker arm is 1.36, mainly concentrated in the fixed pin hole on a rocker and near the small fillet, and the minimum safety factor of the lower rocker arm is 0.485, mainly concentrated in joint place of the rocker arm and rocker arm shaft.

Abstract ( 240 )
The pedestrian lower leg protection is an important issue in a vehicle design. Compared with the vehicle collision, the pedestrian protection collision energy is smaller, and the geometrical characteristics of the lower leg of the pedestrian will have great influence on the collision result. In this paper, the factors affecting the lower leg protection are analyzed, a design is proposed and validated with an example, in a test-correlated lower leg impact simulation. Calculation and analysis results show that by fine-tuning vehicle's shape and the structure design a good pedestrian leg protection design can be realized.

Abstract ( 213 )
With the stability of a counter-tilt slope under bias chasm in mind, based on the rock mass structure cybernetics and combined with the west open-pit mine project of Ping Zhuang, this paper analyzes the failure mode and the landslide mechanism of the counter-tilt slope under bias chasm, using AutoCAD, ANSYS and 3Dslope to model the three-dimensional slope and calculate the slope stability coefficient. The calculation results show that: the three-dimensional landslide modes of the chasm affected zone are: the wedge sliding along the fault plane, the side interface and the weak interface, thus the most dangerous space form of the three-dimensional sliding body is identified; from the stability coefficient under different side interface locations, the influence of the oblique chasm on the slope is revealed. According to the results of the stability analysis, the control scheme of the mining plan is proposed to provide a technical guidance for the open pit mine production safety.

Science & Technology Review. 2013, 31 (28-29): 66-69. ;  doi: 10.3981/j.issn.1000-7857.2013.h2.011

Abstract ( 216 )
The interaction between hammer and formation is a main concern in the dynamic compaction studies. According to the week cemented and porosity characteristics of the unsaturated soil under impact loading, the elasticity behavior of the unsaturated soil skeleton is not important. In this paper, the momentum equation between the hammer and the soil layers is established, and the dynamic compaction is expressed as a process of the layers reaching the ultimate porosity sequentially. The recursive equation based on the above viewpoint is also set up and extended to the whole process of the dynamic compaction. Based on the recursive equation, a computation program is developed, and furthermore, the foundation settlement, the hammer speed, the impact time and others are calculated for the example of the dynamic compaction project in Beijing Garden EXPO. It is shown that the total settlement increases with the impact number, the single settlement decreases with the number and appears to be stable after several impacts. The calculated settlement is in good agreement with the field experimental data. The tamping speed and the settlement with the tamping time are discussed in the end. The momentum recursive method provides a new way for the calculation of the dynamic compaction in the unsaturated under-consolidated soil and could be used in engineering designs.

Abstract ( 198 )
In the process of sediment, the sedimentary system is generally accumulated by multi-sources or mutative sources. In the establishment of a geologic model, the use of a single source can not meet the accuracy requirement. Taking some oversea large-scale deep-water subsea fan, A oilfield, as an example, the two reservoir stochastic simulation methods, the segment method and the trend-line method, are proposed based on the facts that a high-sinuosity deep water turbidite channel is developed widely and the flowline changes from time to time. The segment method is to divide the high-sinuosity deep water turbidite channel according to the geology knowledge and simulate the process separately and independently; the trend-line method is to set a quantitative geologic trend line and simulate the process as an entirety. The segment method applies to different sources and two non-cross sedimentary systems, while the trend-line method applies to the high-sinuosity deep water turbidite channel modeling under the same sedimentary system. Both methods are used to simulate the reservoir distribution of multi-sources or mutative sources in the same grid system, and the results show the spatial distribution characteristics of the high-sinuosity deep water turbidite channel.

Abstract ( 158 )
The geomagnetic field changes acutely during geomagnetic storms. According to Faraday's law of the electromagnetic induction, the change of the geomagnetic field produces a geomagnetically induced current in the power grid, which directly damages the power equipment and threatens the safe operation of the power grid. The more dramatically geomagnetic field changes, the bigger geomagnetically induced current in the power grid becomes, and thus, the greater harm to the power grid. In this paper, based on the H and D components of the recent geomagnetic storm data measured by several mid-to-low latitude geomagnetic observatories, the variation law of the amplitude of north-south and east-west geomagnetic component change rate (dX/dt and dY/dt) pulses with geomagnetic latitude is analyzed when the geomagnetic field changes very severely. Finally, the possibilities of the power grid in different directions being affected by GIC with the change of latitude are discussed. The analysis results will contribute to the evaluation, the measurement and the control of GIC in the current and future power grids in China.

Abstract ( 167 )
By the detection of the liver function and renal function of mice in acute toxicity test that were given Gansuibanxia decoction that adds or subtracts Gansui and Gancao anti-drug combination, we expect that these results provide evidence for acute toxicity experiments. The male Kunming mice of 18-20 g were randomly grouped, including the blank group, the group of Gansuibanxia decoction, the group of Gansuibanxia decoction with Zhigancao removed, the group of Gansuibanxia decoction with Cugansui removed, the group of Gansuibanxia decoction with Zhigancao and Cugansui removed, the group of Zhigancao, the group of Cugansui,the group of compatibility of Zhigancao and Cugansui. Each administration group was divided into five dose groups by diluting to a ratio of 1:0.85. Blank group was given distilled water, the rest groups were given the drugs. The method of administration was maintained for 28 days, then the eyes of the mice that did not die were removed and centrifugated, to detect serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), alkaline phosphatase(ALP), creatinine(CRE), blood urea nitrogen(BUN) levels. The AST results show that, compared with the blank group, the serum AST activity of the group of Gansuibanxia decoction 1, 2 and 3, the group of Gansuibanxia decoction with Cugansui removed 2, 3 and 5, the group of Gansuibanxia decoction with Zhigancao removed and Cugansui 4, the group of Zhigancao 2, 3, 4 and 5, the group of Cugansui 1, 3, 4 and 5, the group of compatibility of Zhigancao and Cugansui 2, 3 and 5 were higher than the blank group and had statistically difference. The ALT results show that compared with the blank group, the serum ALT activity of the group of Cugansui 4 was higher than the blank group(P<0.01). The serum ALT activity of the group of Gansuibanxia decoction with Zhigancao removed 4 was lower than blank group(P<0.05). The serum ALT activity of the group of Zhigancao 2, the group of Cugansui 1, 3 and 5, the group of compatibility of Zhigancao and Cugansui 1, 2, 3 and 5 were higher than the blank group(P<0.05). The blood ALT activity of the rest groups in comparison with the blank group does not have a statistically significant difference(P >0.05). The ALP results show that the serum ALP activity of all the groups does not have a statistically significant difference compared with the blank group. The BUN results show that compared with the blank group, the serum BUN activity of the group of Gansuibanxia decoction 5, the group of Gansuibanxia decoction with Zhigancao removed 2 and 5, the group of Gansuibanxia decoction with Cugansui removed 2 and 3, the group of Gansuibanxia decoction with Zhigancao and Cugansui removed 1 and 2 were lower than the blank group(P<0.01). The serum BUN activity of the group of Gansuibanxia decoction with Cugansui removed 4, the group of Gansuibanxia decoction with Zhigancao and Cugansui removed 3 and 5, the group of Cugansui 2 were lower than the blank group(P<0.05). BUN decreased in the blood of mice that did not die in the experiment of LD50(n), and it is a kidney injuryhas yet to be further experimentally verified. The CRE results show that all of the blood CRE content in comparison with the blank group did not have a statistically significant difference(P >0.05). It can be seen that in the experiment of LD50(n), each group of drugs on the liver and kidney of mice mainly has a certain degree of damage to the liver, and the liver injury of anti-drug combination of the Gansui and Gancao application in the compound compared with two separate application is decreased. In the LD50(n) experiments, the compound containing anti-drug combination of Gansui and Gancao in a certain dose and time of administration showed a certain liver damage of not died mice may come from the anti-drug combination of Gansui and Gancao.

Abstract ( 420 )
There is a great fire risk in the university student dormitory because of its intensive resident rate, the large amount of combustible materials, the complex building structures and the weak fire safety awareness of students. Major accidents always happen once it is out of control. In order to investigate the fire risk of the university student dormitory, an assessment index system including the fire-proof capacities of buildings, the fire load, the fire facilities, the fire-fighting capacities, the evacuation system and the safety management is adopted based on the characters and causes of fire in the university student dormitory. A grey relational assessment model for fire of this type is built according to the grey relational theory. In addition, the fire risk of a male student dormitory in one university in Beijing is calculated with this model and the final evaluated results show that it is in level two, which means that the dormitory is in a relatively safe state. It shows that the valuable fire risk assessment results and the relevant weak links can be obtained by this scientific grey relational method. Thus, the corresponding control and improvement measures could be put forward.

Abstract ( 222 )
With rapid growth of social networking and mobile Internet application technology, derived from more innovative interactive mode and operation behavior, product design thinking has evolved from a three-dimensional shape of the morphological study, to User Experience centric Interface Design and Interaction Design. Immaterial of the product design practice in the face of Human-Computer Interactions and product development processes and evaluation criteria changes, UI design is not limited to Graphical User Interface design, and the article explains the concept of UI design diversification trend. "Tangible User Interface" inherited a real-world product experience, and "Natural User Interface" with a more humane way to simplify operations. By design examples to illustrate the context of the Internet era, TUI & NUI combined design methods for product development, is an important way for User Experience innovative design.

Abstract ( 310 )
It is an efficient way to use the solar energy for photocatalytic H2 and O2 evolutions on semiconductors to resolve the problems of fossil energy shortage and environmental pollution. The photocatalytic systems of H2 and O2 evolutions are very complex and involve a series of issues in science and technology for obtaining the efficient photocatalytic systems of H2 and O2 evolutions, among which the selection of co-catalyst is a crucial one. This paper focuses on the progresses of the co-catalysts of photocatalytic H2 and O2 evolutions, analyzes and introduces the roles of cocatalysts integrating with the principle of photocatalysis. The roles of the cocatalyst as the active sites for H2 and O2 evolutions include the catalysis in the reactions of H2 and O2 evolutions, the reduction of overpotentials and the efficient separation of photo-induced electrons and holes. This paper also introduces the idea of the development of cocatalyts in the photocatalytic systems in the future. It is believed that the efficient combination of dual and multiplex cocatalysts, and the exploration of the non-noble metal cocatalyst are the direction of development in the future.
