These results indicated that a well structured anatase TiO2 was obtained by impregnation method under 500℃. Flow rate, in the activity test, could be neglected for mass transfer effects. As a matter of fact, relative humidity played the most important role in this reaction. The highest removal efficiency was obtained while relative humidify of 56.8%. Water molecules are sources of ; however, excessive water molecules could inhibit reactions by competing activity sites with organic containments. In the regeneration test, photocatalyst could be reactivated through a running water vapor with UV light illumination process.
研究结果指出,以含浸法制备之触媒於500℃锻烧下,具有良好的锐钛矿晶体结构;另外在活性测试的部份,流量的增加,污染物之去除效果不受影响,所以本实验选择以200ml/min之流量可忽略质传影响;湿度扮演重要的角色,当RH=56.8%时去除效率最高,主要因水气是产生氢氧自由基的主要来源,但是过多之水气可能与有机物竞争触媒表面上的活性位置,因而抑制反应的进行;初使浓度对去除率之影响中得知,初使浓度的高低不会影响触媒对有机物的催化能力,实验使用之触媒量适合催化200~250ppm之有机物,可藉由增加触媒量提高对有机物之催化能力;此外再生的测试,触媒可经由连续曝水及紫外光的照射,使触媒恢复原有的活性,可再次利用。

The main results of the investigation are as following:(1) Some important criteria for the design of multi-layer structure are acquired: the ratio of the layer thickness to the contact diameter should be controlled to a value about 0.8; increasing the number of the gradient layers and elasticity modulus of the top layer would benefit to the yield strength and the stress status at the interface.(2)By means of molecular dynamics simulations for a indentation and sliding process, it is discovered that dislocations of 45 direction to the surface occur in the surfaces layer, which is correspond to the direction of the plastic flows observed in the macroscopic continuous medium. The irreversible deformation caused by the dislocation and the atom piles at the surface are responsible for the irreversibility of the force response. They are also the main factors for the friction generation. The temperature and the indentation velocity have significant effects on the deformation behaviors of the material of the surface layer. The yield strength would increase obviously if the indentation velocity is greater than 10 m/s.(3)A method to evaluate the fracture toughness of coating by estimating the crack-density functionβof a Wicker''s indentation was proposed. Meanwhile a new surface treatment technology was developed using non-equilibrium plasma.(4)A MD-FE hybrid method and corresponding software was developed to analysis the tribological behaviors for multiplayer system.

The nonlinearity and discrete gradient inherited in CAViaR model is a conundrum for parameter estimation. We take the asymmetric Laplace distribution with scale parameter as the error process; indicate the variance has a minimum positive value when the scale parameter is a constant, conflicting with the distribution of real financial data. Further we estimate the parameters of indirect TARCH-CAViaR model base on Bayesian framework and Markov chain Monte Carlo method. The optimal scale parameter can also be obtained by Markov chain Monte Carlo method.
