The leaching rule of nano particles from E.camaldulensis Wood has an important significance in the forestry research and paper making engineering. Therefore, based on the single-factor method, the fresh E. camaldulensis shavings were treated by LiOH in a concentration range of 0.5%~25% g/mL and the duration is 3, 16 and 24 hours respectively. The extraction mass was analyzed and the results were discussed. The filtrates were analyzed by ZETA and SIZER. The results were following as: (1)The extraction mass arrived at the maximum value when concentration is about 17.5%. (2)The micro/nano particles in the diameter of 531-1720 nm, 531-17200 nm, 164-531nm is the most at the extracting time of 3h, 16h, 24h, respectively (2) The diameter the micro/nano particles of wood extractives and hemicellulose is chiefly between 164-1720 nm according to number fraction. However, there are micro particles in the diameter of more than 1720nm when LiOH concentration is biger than 15%. The micro/nano particles in the diameter of 531-1720 nm, 531-1720 nm, 164-531 nm is the most at the extracting time of 3h, 16h, 24h, respectively.","PeriodicalId":6416,"journal":{"name":"2009 Symposium on Photonics and Optoelectronics","volume":"34 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81869170","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}

By the method of Physical Optics Propagation, the output beam's characteristics including the waist, the waist position, the far field divergence, and the energy distributing characteristics were obtained; rules of the image aberration's effect on the output beam's characteristics and the expanding ratio were analyzed. Then, taking encircled power and uniformity of the output beam for standards, the relation curve of the optimal expanding ratio and the launch distance was achieved. The results reveal that the width of the output beam at a distance of 100 m is less than 250 mm, a maximal collimation distance can be about 2 km, and the energy focus degree and the uniformity of the far field laser are also quite well. These indexes can satisfy the demands of transmission and control of laser beam in laser propulsion technology. Firstly, this paper found the models of the expanding system and the incidence beam. Then, by the method of Physical Optics Propagation, the process of transmission and gradual change of the output laser beam is studied, the characteristic parameters of space and energy distribution were analyzed, the optimal distance between the primary and secondary mirror at definite launching distance were acquired. Finally, taking encircled power(PIB) and uniformity of the laser beam for standards, the optimal expanding ratio at some distance was achieved. The results can be used in the transmission and control of the laser beam in laser propulsion technology.","PeriodicalId":6416,"journal":{"name":"2009 Symposium on Photonics and Optoelectronics","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89747826","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 proposed algorithm can be applied to asymmetric surfac plasmon resonance (SPR) curves often obtained by a gold-based SPR biochemical analyzer and evaluated by the numerical calculations. The validity and efficiency of the algorithm were demonstrated by a comparison of the numerical calculation results with the experimental results obtained by using the SPR biochemical analyzer to measure the ethanol solutions with five concentrations of 10, 20, 30, 40, 50 wt.%. The sensitivity of the SPR biochemical analyzer was fairly enhanced by the improved centroid algorithm that we argued in this work even without the assistance of a laptop computer. In comparsion with the first-order centroid algorithm, the experimental results further showed that the errors of measurement could be reduced when such an improved centroid algorithm was used.","PeriodicalId":6416,"journal":{"name":"2009 Symposium on Photonics and Optoelectronics","volume":"4 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2009-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90641848","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}
