Phosphate was removed from aqueous environment by corundum-hollow-spheres supported caclined hydrotalcite (cHT) thin films. Mg-Al-CO3 hydrotalcite (HT) thin films were deposited on corundumhollow-sphere substrates by hydrothermal homogeneous precipitation at 120℃for 30-240 min and cHT thin films were obtained by annealing of the HT thin films at 500℃for 180 min. Their crystal phase, morphology and microstructure were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The results show that homogeneous, well-crystallized and hierarchical flower-like thin films were deposited firmly on the surface of the corundum. The mechanism of nucleation and growth of the HT thin films was fitted well with the anion coordination polyhedron growth unit model. To determine the absorption of phosphate by this adsorbent, different bed depth (10-30 cm) and flow rate (1.0-3.0 m L/min) were examined by column experiments. The highest removal efficiency of phosphate amounted to 98.5%under optimum condition (pH=7.2). The adsorption capacity increased as the bed depth increased and decreased as the flow rate increased.

伴随着我国人口老龄化程度加剧,提高企业劳动投资效率是优化宏观经济要素配置与提升微观企业竞争优势的重要手段。本文采用中国A股上市公司数据,实证检验高管薪酬契约参照点效应对企业劳动投资效率的影响。研究发现,高管薪酬相较于契约参照点的得益越少,企业劳动投资效率越低,且上述影响主要存在于垂直参照点和水平参照点维度。此外,相较于得益区域,高管薪酬契约参照点效应对企业劳动投资效率的影响在损失区域更高。进一步,高管薪酬垂直参照点效应的影响显著高于水平参照点效应。异质性分析表明,相较于劳动投资不足,高管薪酬契约参照点效应更易导致企业劳动投资过度;相较于劳动密集度高的企业,高管薪酬契约参照点效应的影响在劳动密集度低的企业更大。此外,完善的监督机制(分析师关注、企业内部控制)与激励机制(高管晋升预期)能够显著缓解上述影响。本文的结论能够从薪酬契约治理角度为改善企业劳动投资效率提供一定的管理启示。

针对大口径光学元件表面疵病检测中子孔径图像数量较多、在全孔径拼接过程中存储及处理数据量大的问题,提出了一种基于子孔径特征数据集的光学表面疵病拼接方法。该方法由子孔径图像及其重叠区域图像中提取疵病特征数据构建子孔径特征数据集,并通过特征数据集实现子孔径相对位置关系确定及全孔径疵病拼接。通过实验验证,本文方法可以有效实现全孔径疵病目标拼接,并且与基于模板匹配法的全孔径图像拼接方法相比,两种方法获得的全孔径疵病图像的疵病检测结果基本一致,而本文方法在拼接过程中处理的子孔径特征数据集的数据量为3.26 MB,获得的全孔径疵病数据转换出的全孔径疵病图像的数据量为20.9 kB,有效降低了全孔径拼接过程中的处理及存储数据量。
