The construction control is necessary in continuous rigid-frame bridge,assuring the required safety and quality.How to effectively monitor the linearity and stress during the construction process has become a hot issue in engineering research.Based on the construction of Liangjiang Bridge with its maximum span being 170m and maximum pier height being 120m,the monitoring and controlling methods on cantilever construction of prestressed continuous rigid flame were discussed from three perspectives including the plane alignment,elevation and stress.The determination method was presented on vertical mold elevation and field monitoring data in each cantilever segment.The disparity was clarified between the measured values and the theoretical values of the stress in key section.The idea was then proposed for long-term remote monitoring in bridge engineering.The research methods and results will herein provide valuable reference for similar bridges.

金属空气电池属于燃料电池的一种,其燃料采用金属(镁、铝、锌等)及其合金板,其电解质可以采用中性盐溶液或碱溶液,其阴极为催化层和带有防水透气层的多孔扩散电极。在金属空气电池的开发研究过程中,其阴极高效氧还原催化剂的开发研究是其重要问题之一。研究了催化剂前体聚合卟啉(PTPPM)和聚合酞菁配合物(PPcM) (M=Co、Fe)的制备方法和工艺。用UV-vis、IR对催化剂前驱体进行表征,结果表明,得到
储热材料在压制成型过程或封装填充过程中易产生空间分布不均，加之储热材料自身热阻的存在，以及换热器结构本征特性，极可能导致整套相变储/释热换热器内部储热材料温度分布的不均匀性，即沿单体换热元件(管束)轴向方向以及沿整套换热器迎风面垂直方向(热流体流动方向)，储热材料的温度梯度可能过大，这将造成在换热器的某些管束区域内，储热材料的温度已越过相变点，且达到最高允许温度值，而某些管束区域内，储热材料的温度
