Field monitoring results indicate that, total deformation of Lane5101 is greater than Lane 5102 at the same amount of time, the ribs convergence value of Lane 5101 is 250mm, while Lane5102 is between 130mm to 150mm. The anchor¡¯s anchorage of upper rib is greater than lower rib, and the activity level of rock of upper roadway rib is greater than lower rib. The anchorage of cable at the middle of roof is larger than the sides of roof. The anchorage of cable at the middle of roof floats between 165KN and 168KN, while there is a big difference between the two sides of roof. Geological conditions are the main factors affecting the stability of roadway. The research also shows that the support of bolt and cable integration is an effective method to improve the surrounding rock stability of large section roadway.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"23 1","pages":"2443-2447"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89556972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The catalysts were characterized using N2adsorption-desorption, X-ray diffraction (XRD) and temperature programmed desorption (NH3-TPD). The effects of Mo/Ni molar ratio and reaction temperature on the hydrodeoxygenation activity of the catalysts were investigated emphatically using acetic acid and phenol as probe compounds. The results showed that the catalysts prepared by the sol-gel method can possess higher specific surface area and the double mesoporous structure. The ¦Â-NiMoO3 phase determined by XRD was existed in the catalysts. For Mo/Ni molar ratios between 0.0 ~ 0.8, the pore volume, the specific surface area, the medium strong acidity and hydrodeoxygenation activity of the catalyst are not monotonically increasing functions of Mo/Ni ratio. The catalyst with Mo/Ni ratio of 0.6 exhibited the highest hydrodeoxygenation activity. At 0.3MPa, the deoxygenation percentage of the phenol was 99.0% at 210¡æand 99.9% at 270¡æ for the acetic acid, respectively.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"411 1","pages":"2383-2386"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79911625","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And an evaluation system for comparing efficiencies of these measures have been built, indictors such us economical effects, payback period time, changes in soil erosion rates, nutrient content, microclimate, and social benefits are recommended. Forest enclosure, embankments, and biomass pools are the most economically measures with a short payback period while low efficiency forest reform, fruit trees planting and shifting slope to terrace measures had remarkable effects on reducing soil erosion and protecting soil and water resource, pear trees can be replaced by other cash crops to avoid long payback period.","PeriodicalId":6328,"journal":{"name":"2011 International Conference on Computer Distributed Control and Intelligent Environmental Monitoring","volume":"1 1","pages":"2420-2423"},"PeriodicalIF":0.0,"publicationDate":"2011-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76734166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
