When the model test is made, the model is often excavated. When model is excavated, the mark spots are removed. This causes big trouble in computer automatic recognition and handling, program of automated grid must be compiled again. Model test is made by automated grid, and images are handled by the program improved. Results show that the program woks well and can meet the practical needs Number of references: 10 Ei main heading: Rock mechanics Ei controlled terms: Deformation | Automatic target recognition | Models | Excavation Uncontrolled terms: Automated grid | Model test | Displacement field | Model surface Ei classification codes: 483.1 Soils & Soil Mechanics | 421 Strength of Building Materials; Mechanical Properties | 723.5 Computer Applications | 405.2 Construction Methods Treatment: Experimental (EXP) Database: Compendex 2. Quantitative determination of saponins from bulbs of lily Accession number: 04158112624 Authors: Ji, Hong-Wu ; Ding, Xiao-Lin First author affiliation: Dept. of Food Sci. and Technol., Zhanjiang Ocean Univ ., Zhanjiang 524025, China Serial title : Linchan Huaxue Yu Gongye/Chemistry and Industry of Forest Products Abbreviated serial title :Linchan Huaxue Yu Gongye Volume: v 23 Issue: n 4 Issue date: December 2003 Publication year: 2003 Pages: p 54-58 Language : Chinese ISSN: 0253-2417 CODEN: LHYGD7 Document type: Journal article (JA) Publisher: Chemistry and Industry of Forest Products Abstract: A quantitative analytical method of lily (Liliwm brownii var. colchesteri) saponins was studied by colorimetry. Results show that lily saponins can be well calculated according to their colorimetric absorption at 406 nm by using ultrasonic treatment of the sample in methanol for 1 h, and extracting for 4 times with n-butanol (1:1, volume), applying HClO 4 (5 mL), 20 min at 55°C for colorimetric reaction. The method established has less interference, good precision, simplicity, rapidity, and can be well adopted for determination of saponins in a great deal of lily samples.

Thermooxidative degradation methyl methacrylate-graft-natural rubber Accession numbe r: 03407661605 Authors: Li, Si-Dong ; Wang, Chen ; Xu, Kui ; Peng, Zheng First author affiliation: College of Science, Zhanjiang Ocean University , Zhanjiang 524088, China Serial title: J ournal of Applied Polymer Science Abbreviated serial title: J. Appl. Polym. Sci. Volume: v 90 Issue: n 5 Issue date: Oct 31 2003 Publication year: 2003 Pages: p 1227-1232 Language: English ISSN: 0021-8995 CODEN: JAPNAB Document type: Journal article (JA) Publisher: John Wiley and Sons Inc. Abstract: The thermooxidative degradation of methyl methacrylate-graft-natural rubber (MG) at different heating rates (B) has been studied with thermogravimetric analysis in an air environment. The results indicate that the thermooxidative degradation of MG in air is a onestep reaction. The degradation temperatures increase with B. The initial degradation temperature (T o ) is 0.697B + 350.7; the temperature at the maximum degradation rate, that is, the peak temperature on a differential thermogravimetry curve (T p ), is 0.755B + 368.8; and the final degradation temperature (T f ) is 1.016B + 497.4. The degradation rates at T p and T f are not affected by B, and their average values are 46.7 and 99.7%, respectively. The maximum thermooxidative degradation reaction rate, that is, the peak height on a differential thermogravimetry curve (R p ), increase with B. The relationship between B and R p is R p = 2.12B + 7.28. The thermooxidative degradation kinetic parameters are calculated with the Doyle model. The reaction energy (E) and frequency factor (A) change with an increasing reaction degree, and the variational trends of the two kinetic parameters are similar. The values of E and A increase remarkably during the initial stage of the reaction, then keep relevantly steady, and finally reach a peak during the last stage. The velocity constants of the thermooxidative degradation vary with the reaction degree and increase with the reaction temperature.

Abstract: With the development of Internet, we put forward high requests for information retrieval. First, efficiency; second, personalizing. In this paper a model and an algorithm are proposed which are according to the user's retrieval habit of learning and the intelligent information retrieval system that has inner relativity of three layers agent structure. This is a trend that using artificial intelligence to enhance the efficiency of information retrieval, which need more research and practice.
