1GIS-based risk analysis of debris flow:an application in Sichuan,southwest China显示文摘Debris flow is a serious geologic hazard in China.It is estimated that nationally debris flows cause up to 2 billion RMB(250 million US$) in damages and 300-600 deaths and injuries annually.To mitigate debris flow hazards,it is necessary to map,model,and identify zones of debris flow hazards and vulnerability as to inform the local people about the potential risk with a geographic information system.This research presents a regional scale case study modeling debris flow risk(hazard and vulnerability) in Sichuan Province,Southwestern China.In this area,3,290 debris flows have been identified and the spatial-temporal distribution and activity characteristics of them have been documented.Based on the available meteorological data,a Digital Elevation Model with the rate of 1:250,000 and a regional geological map,the 24-hr rainfall threshold(y) for debris flow occurrence is closely related(significant at 99% confidence level) to the index(x) defined using a geology factor(rock hardness:a) and a topographical factor(channel gradient:d) where y = 21 + 10200 / x,in which x = 2.7 × ea + 1000 × d.The discipline is constructive in developing the rainfall threshold for debris flow activity in remote mountainous areas that lack data.For a given watershed,a four-level debris flow hazard map is developed by comparing the rainfall threshold to the design rainfall intensities with 50-,20-,and 5-year average recurrence intervals,respectively.The degree of debris flow vulnerability is determined by the watershed socio-economic conditions.A four-class debris flow risk map,at the final phase of the research,is generated by combining debris flow hazards and vulnerability.With the debris flow risk assessment,the Sichuan Province is classified into the slight,moderate,severe and very severe regions,which accounts for 36%,19%,20% and 25% of total area respectively.B.

14Efficient one-pot hydrogenolysis of biomass-derived xylitol into ethylene glycol and 1,2-propylene glycol over Cu–Ni–ZrO_2 catalyst without solid bases显示文摘The directly selective hydrogenolysis of xylitol to ethylene glycol(EG) and 1,2-propylene glycol(1,2-PDO)was performed on Cu–Ni–ZrO_2 catalysts prepared by a co-precipitation method. Upon optimizing the reaction conditions(518 K, 4.0 MPaH_2 and 3 h), 97.0% conversion of xylitol and 63.1% yield of glycols were obtained in water without extra inorganic base. The catalyst still remained stable activity after six cycles and above 80% total selectivity of glycols was obtained when using 20.0% xylitol concentration. XRD, TEM and ICP results indicated that Cu–Ni–ZrO_2 catalysts possess favorable stability. Cu and Ni are beneficial to the cleavage of C–O and C–H bond, respectively. To reduce the hydrogen consumption, isopropanol was added as in-situ hydrogen source and 96.4% conversion of xylitol with 43.6% yield of glycols were realized.Shenglin Li Yifan Zan Yuanyuan Sun Zhichao Tan Gai Miao L.

15HAZ CRACKING AND HOT DUCTILITY OF Ni_3AI CONTAINING Zr ALLOY显示文摘The HAZ cracking test in EB welding condition and hot ductility test show that the cracking mechanism is the formation of Ni - Ni5Zr eutectic which is resulting from the enrichment of Zr in grain boundaries during welding.In order to eliminate HAZ cracks the diffusion and recrystalization anealing treatment after cast and during cold rolling should be conducted in vacuum or protecting atmosphere and at the same time a slow welding speed is necessary.B.

19NUMERICAL SIMULATION OF PENETRATION PROCESS BASED ON THE VARIATION OF HEAT TRANSFER CONDITION显示文摘In this paper, the process of dynamic heat output in a welding pool and the variation of the penetration caused by the section change of the workpiece are analyzed using numerical simulation technique of thermal field. It is concluded that the variation of temperature gradient in HAZ along the length and width direction reflects the heat output of the welding pool, and that the output of the welding pool has a homogenous relationship to the pool penetration.L.
