弹性波层析成像及其在土木工程中的应用

对弹性波层析成像理论和算法进行系统研究。射线追踪是建立在几何光学近似的基础上,合理选择弹性波源使之在介质中有较大的波速梯度,则在土木工程中应用弹性波层析成像能够满足其理论前提;提出二阶段射线追踪的快速方法,第一阶段采用改进的扫描法初选射线路径,第二阶段对初选射线路径进行扰动分析确定最终射线路径;讨论离散反演问题解的性质,特别是对于混定问题采用奇异值分解理论可获得满意的解估计,在减小解方差的同时也降低解的分辨半;研制弹性波层析成像系统,数值仿真表明软件正确可靠,工程实例表明该技术在土木工程中有显著的推广应用价值。

Plasma degradation of dyes in water with contact glow discharge electrolysis

Contact glow discharge electrolysis (CGDE) of two dyes, weak acid brilliant red B and weak acid flavine G, was investigated under different concentrations, temperature and mediums. From the variation of their concentration with the reaction time, it was demonstrated that the oxidation would be a first-order reaction. On the base line of UV spectra of solution in the degradation process, we deduced that two dyes underwent the oxidative degradation in CGDE. The rate constants, relevant coefficients and the decolorization degree were displayed under different conditions.     

Bioaerosol characteristics in hospital clean rooms

Bioaerosol characteristics were evaluated in hospital clean rooms with different class levels. For total particles, an airborne particle counter was used to determine the particle size ranges (0.1, 0.2, 0.3, 0.5, 1 and 5 microm) for air inlets and patient beds. An Andersen 1-STG sampler was used for bacterial and fungal collection. For aerosol characteristics, it was found that some air inlet particle levels were higher than 100000/foot(3) in class 100000 clean rooms. In addition, it was clearly demonstrated that particle concentrations in patient beds were much higher than those for air inlets. Human activity might play a role in these particle concentration differences. Moreover, it was demonstrated that bacterial and fungal concentrations ranged from 1 to 423 and from 0 to 319 CFU/m(3), respectively. For class 100 clean rooms, no particles were ever found. In addition, bacterial concentrations were found to be in the range of 0-32 CFU/m(3) and there were no fungal aerosols. For operating rooms of class 10000, some of the particle levels observed were higher than 10000/foot(3). Furthermore, the average level of bacterial aerosols was 88 with a range of 13-336 CFU/m(3). In addition, fungal levels ranged from 0 to 51 with a mean value of 4 CFU/m(3). It was indicated that bacterial levels were higher than fungal ones, which might be related to human sources. Moreover, there were weak relationships among class level, particle concentration and bioaerosol levels.
