The results show that the specific surface area is 156m2/g after acid treatment of 5h. The loading quantity of active component is linear with coating times. The influence of coating times on the gas composition is quite small, and the sum of the content of H2 and CO keeps as high as 90 vol %. After 6h catalytic reaction, the phase structure of catalyst hasn't any change, and the tar conversion decreased from 87.4 wt % to 81.3wt %.

Presently, the bottleneck of application of magnesium alloys as biomaterials is that their corrosion speed is too rapid. The magnesium alloy will seriously erode before the tissue or organ recovers. Moreover, the excessive hydrogen gas that cannot be processed by human body will generate in the corrosion process. Therefore, improving the corrosion resistance is the key to successfully apply magnesium alloys in the field of biomaterials. In present, magnesium alloy Mg-8.0Al-1.0Zn-1.0La fabricated by authors in prior research was processed by micro-arc oxidation technology for improving the corrosion resistance. Results showed that the anodic polarization behavior transferred from the active dissolution to the self-passivation after micro-arc oxidation. The self corrosion current density decreased 3∼5 order of magnitude. The micro-arc oxidation film generated in-situ on the surface of Mg-8.0Al-1.0Zn-1.0La alloy constitutes of ceramic materials, such as MgO, MgSiO3, Mg2SiO4 and Al2O3. The ceramic film can protected the magnesium matrix from eroding.","PeriodicalId":6400,"journal":{"name":"2011 Second International Conference on Mechanic Automation and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80855539","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}

As the capital of thirteen dynasties, Luoyang is the most representative in metropolis space, as its evolution process reflects all the features from early to mid stage of China's ancient capital city space form. By analyzing the development during the important periods of Luoyang through researching literature materials, it can be concluded that with constantly improving of etiquette thoughts, its space form improved ceaselessly and eventually comes to the metropolis space form marked by Chinese monarchy rules characteristics. Thus it can be clearly understood the development and change rules of metropolis space form, which can provide important reference for research in China's ancient capitals space form in later period.","PeriodicalId":6400,"journal":{"name":"2011 Second International Conference on Mechanic Automation and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81130099","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 simulated results show that the lengths of the straight ducts before and behind the measuring element are too short to meet the requirement of the flow rate measurement of the primary air due to the compact design in many domestic power plants. The actual flow at the cross section where the measuring element is installed is irregular and disordered and the air velocity obtained by the single measuring element is not the area-weighted average value. The blowing of cool primary air also aggravates the disorder of the flow fields. It is concluded that the flow rate of the primary air can not be measured precisely. The numerical simulation method could be adopted to measure and calibrate the flow rate of the primary air, which can avoid the limitations of the existing method. This solution could improve the precision and reduce the cost of the measurement, which will be a good alternative for the domestic power plants.","PeriodicalId":6400,"journal":{"name":"2011 Second International Conference on Mechanic Automation and Control Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78580671","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}
