Chloropcroxidase （CPO） was immobilized by konjac glucomannan （KGM） on the 1-butyl-3-methyl imidazolium tetrafluoroborate [BMIM][BF4]/Nafion modified glassy carbon eloctrode. The electrochemical behaviors of the immobilized CPO were investigated by cyclic voltammetry. The results showed that CPO was successfully immobilized on the GCE and underwent fast direct electron transfer reactions with the formal potential at -0.3 V vs. SCE. The modified electrode showed a good catalytic activity for elcctrocatalytical reduction of O2 and H2O2.

To develop beam splitters for soft X-ray laser Michelson interferometer at 13.9 nm, Mo/Si multilayers of 100 nm thickness deposited on both sides of silicon nitride were fabricated by using DC magnetron sputtering. Initial evaluation of their reflectivity and transmission showed that reflectivity and transmission were above 10% and 25%. The broadband analyzers have been designed, fabricated and characterized for 13～20 nm polarization measurements. The measured results are in good agreement with the design. The supermirrors with different angular intervals at 0.154 nm have been designed, fabricated and characterized.

基于乘客出行感受,提出了公交运行时间稳定性评价指标,并给出了计算模型。该指标能够直接反映公交专用道设置效果,同时体现乘客利益,适合作为公交运行可靠性评价指标。根据上海市路侧公交专用道代表性公交线路的实测跟车调查数据,得到了公交运行可靠性及信号灯延误比例与道路里程的关系曲线,进行了路侧公交专用道长度对公交运行可靠性的影响程度分析。最后提出了单条路侧公交专用道设置长度合理值的建议,设置长度低限值应取6.5km或线路总长的40%这两个值中的较小值,从而为国内公交专用道设计提供理论依据。
