This paper presents the substrate temperature dependence of opto-electrical properties for transparent conducting Al-doped ZnO films prepared on polyisocyanate (PI) substrates by r f sputtering. Polycrystalline ZnO:Al films with good adherence to the substrates having a (002. preferred orientation have been obtained with resistivities in the range from 4.1×10-3to 5.3×104 Ωcm, carrier densities more than 2.6×102. cm-3 and Hall mobilities between 5.78 and 13.11 cm2.V/s for films. The average transmittance reaches 75% in the visible spectrum. The quality of obtained films depends on substrate temperature during film fabrication.

Several kinds of carrier (porous polyurethane foam, Ca-alginate, Ca-alginate/PAM, Ca-alginate/PVA, Ca-al-ginate/PVA/PAM) were used to immobilize Penicilllium sp. ZD-Z1, and found that the efficiency of porous polyu-rethane foam immobilized cells are better than that of others catriers. The cells of Penicillium sp. ZD-Zlwere im-mobilized in the matrix of porous polyurethane foam and packed in a bubble column bioreactor for simultaneous pro-duction of chitosanase and degradation of chitosan in situ. The optimal ratio of immobilization were as following:matrix amount is 0. 4g-matrix/50mL medium;pH is 5. 0;span for shaking flask culture is 48 hours. It is illustrated

The origin of arcuate islands and deep-sea trenches has been studied for a long time and various interpretations have been proposed. In this paper, some analytical models are put forward from a geometrical viewpoint and then the theoretical dip angles of the underthrusting slabs of circum-Pacific island arcs are computed and compared with those of the Benioff zone. As a result, it is found that the dip angle of the underthrusting slab is one of the main factors determining the curvature of the arcuate structure. The authors consider that this result may contribute to the plate theory.

The oxidation kinetics of O'-SiAlON-ZrO2.composite ceramics in the temperature range of 1373-1773K has been studied. The oxidation experiments with powder and plates of O'-SiAlON-ZrO2.composite ceramics in air have been carried out. The overall activation energy of oxidation reaction is 2.3.69 kJ/mol. The products and structures of O'-SiAlON-ZrO2.oxidation layer have been analysed by XRD (X-ray diffraction), SEM (scanning electron microscope) and AFM (atomic force microscope).

β-glucan is a polysaccharide compound closely related to the quality of barley used as malting, feed and food. Low β-glucan content is expected for brewing and feed barley, while high β-glucan content is desirable for food barley. The β-glucan content of barley genotypes collected from various areas of china as well as from Canada and Australia were assayed. Meanwhile a multi-locations trial was conducted to determine β-glucan content of 10 barley cultivars in 8 locations for two successive planting years. The results showed that barley genotypes from Tibet and Xinjiang had higher p-glucan content and the genotypes with higher than 8% of P-glucan content were detected in Tibet barleys, being valuable for use in the development of healthy food. Barley cultivars being planted now in winter-sowing areas of china had basically the same β-glucan content as those from Canada and Australia. Barley seeds produced in {2. had lower β-glucan content than seeds from the original areas. There was a highly significant difference in β-glucan content among 10 barleys, 8 locations and between years. On an average of two years, Xiumei 3 and Kongpei 1 had the highest and lowest β-glucan content, respectively, and Taian and {2. produced the highest and lowest P-glucan content barley seeds, respectively. Analysis of AMMI model showed that interaction effect between cultivar and environment was highly significant in both experimental years, and was dependent on cultivar, suggesting that it is important to plant the suitable cultivars in a particular area in order to obtain barley seeds with reasonable β-glucan content.
