And artificial rerating process is both time consuming and laborious. So the author in this paper applied the Uadj Scheme and the Sadj Scheme to HSK (advanced) essay scores to examine rating errors and to compare these two schemes. The study shows that both of these two schemes can diminish raters' errors and promote rating efficiency, which therefore can be substitutes for raters' rerating and that compared with the Sadj Scheme, the Uadj Scheme is superior.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"60 1","pages":"1148-1150"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82090529","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 WST in Lake Taihu has a good relationship with the algae bloom. Thermal infrared remote sensing will provide a effecitve tool for detecting the WST. China HJ satellite is another satellite monitoring environment pollution and natural disasters which is subsequent to China FY, CBERS and HY satellite launched. With HJ/IRS images, the WST in Lake Taihu is retrieved by a generalized single channel algorithm. The results show that the retrieval accuracy of HJ/IRS image is above 1□ in Lake Taihu. As its high spatial and temporal resolution, HJ/IRS image is desirable to use for retrieving temperature of land waters. The WST in Lake Taihu can occur constantly spatial and temporal change. The WST is various in the different area, which can be due to the direction and velocity of water current. And the WST is always higher in the surrounding area than in the centre. This may result from the effect of inlands climate.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"11 1","pages":"560-565"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91120784","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}

A new method is proposed based on the object direction aiming at the demand of the stereo mapping for airborne SAR image. Using the method, the single SAR image and DEM data are enough comparing with the traditional method that the two SAR images are indispensable for calculation. The paper proposes the space intersection formula for the new method that is used for stereo positioning. The vertical parallax is cleaned between the stereo images by using the new method and the horizontal parallax is preserved or increased. The method is used for stereo interpretation and stereo positioning in the SAR image mapping. The method has been used on the project of the National West Mapping Project.

The simulation results show that the regional air-sea coupled model RegCM3-POM has a better performance in simulating the mean summer (from June to August) precipitation over China, and the distribution of the rainband in the coupled model is more accurate than that in the uncoupled model RegCM3. The improvement of the rainfall simulation ability is remarkable over the Yangtze River Valley and in South China. Compared with the ECMWF ERA40 re-analyses, the convective precipitation simulation ability of RegCM3-POM has been improved. The space correlation coefficients between the results of RegCM3-POM and ERA40 data are above 0.6, and the coefficients between the results of RegCM3 and ERA40 data are about 0.4. The stratiform precipitation simulation ability of RegCM3-POM is also improved. However, both the two models overestimate the percentage of convective precipitation, and underestimate the percentage of stratiform precipitation. In order to improve the simulation ability of precipitation, the cloud precipitation schemes of the models may be modified.","PeriodicalId":6408,"journal":{"name":"2009 International Conference on Environmental Science and Information Application Technology","volume":"34 1","pages":"1305-1307"},"PeriodicalIF":0.0,"publicationDate":"2011-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73873066","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}
