The effects of variable properties on flow and heat transfer were also studied. 1. SIMPLEC algorithm was used to simulate the laminar natural convection flow in horizontal concentric annuli with the assumption of constant properties. Numerical studies range are as follows: Ra〓 number 100～10〓, radius ratio 1. 2～10.Velocity and temperature distribution profile and the heat transfer result were derived. The comparison of heat transfer results under the boundary condition of constant heat flux and constant wall temperature was also made.

The structural and photocatalytic properties of TiO〓 as well as surface acidity were greatly improved by sulfation. SO〓〓/TiO〓 solid superacid with Hammett constant Ho less than -12.14 was prepared by treating the TiO〓 with 1.0mol. L〓 sulfuric acid solution and then calcining at 450℃ for 3h. When compared to unmodified TiO〓, the SO〓〓/TiO〓 superacid catalyst exhibited higher anatase content, smaller crystal size, higher specific surface area, centralized pore size distribution, and the blue-shifted band edge of uv-vis adsorption spectra. Furthermore, the SO〓〓/TiO〓 superacid also showed excellent reaction activity and stability for CH〓Br photocatalytic decomposition even under the moist reaction conditions. The apparent quantum efficiency of SO〓〓/TiO〓 was 10 times of that of TiO〓 catalyst for the photocatalytic degradation of bromomethane. Therefore, the SO〓〓/TiO〓 superacid catalyst is promising for practical application in environmental remediation.It was found that both L and B acid sites exist on SO〓〓/TiO〓 photocatalyst while only L acid sites on TiO〓 photocatalyst. On the basis of experimental results, the synergistic model of superacidic centers was proposed for SO〓〓/TiO〓 photocatalyst to explain the photocatalytic behavior and the mechanism of superacidifing effects, assuming that the adjacent L and B acid sites induced by SO〓〓 comprise cooperatively the superacidic center on superacid photocatalyst. The group cooperation of the superacidic center could strengthen the surface acidity, increase surface acid sites and the adsorbtion of O〓, promote separation of photogenerated electron-hole pair, enhance the interfacial transfer of charges and reversibility of water adsorption. Consequently the excellent photocatalytic activity, reaction stability and resistibility to humidity of SO〓〓/TiO〓 superacid photocatalyst may attributed to the group cooperated effect of the superacidic center on the photocatalyst.

The experimental results were analyzed by data processing software and well-fitted regression equation was established. Effects of ball milling parameters, such as raw material diameter, speed, ratio of raw materials, grinding media and alternating time, on the enzymolysis were analyzed. The optimal parameters of ball milling pretreatment of the corn stalk were as follows: particle size of raw material of 0.5 mm, speed of 340 r/min, the raw material content of 3.4 g, the number of ball of 15 (Ф= 10.0 mm), alternating running time of 5 min.
