Energy conservation research of dehumidification system for main cable anticorrosion of suspension bridge

The necessity of the main cable anticorrosion for suspension bridge is described, and operating principles and composition of main cable dehumidification system are analyzed. An idea using the waste heat of high temperature outlet air of dehumidification system to heat up regeneration air of rotary-type dehumidifier is put forward in this paper. The concrete scheme is to install a heat exchanger on air-out pipeline of roots blower and air-in pipeline of regeneration electric heater of rotary dehumidifier. Air preheated by the heat exchanger enters regeneration electric heater of rotary-type dehumidifier. Energy conservation of main cable dehumidification system for the Yangtze River highway bridge is calculated, and the results show that energy conservation rate can reach 44 %.     

Butterflies (Lepidoptera: Papilionoidea) of Mount Kilimanjaro: introduction and family Papilionidae

This article marks the beginning of a short series on the butterfly fauna of Mount Kilimanjaro. It commences with a brief overview of the topography, tectonic history, climate, ecological zonation and conservation significance of Africa's highest mountain. Following an introductory account to the butterfly fauna, the rest of this paper presents an annotated checklist of the swallowtails (Papilionidae). Eight papilionid species are currently believed to occur within the main forest zone, from 1800 to 2800 m (in places this zone extends down to c.1600 m). Another 10 have been recorded from the lower slopes, which include some disturbed forest and forest relicts, from 700–1800 m. The need for better data is discussed in light of the suggestion that the butterflies of Mount Kilimanjaro could become a focal group for monitoring effects of climate change. An identification key to families, together with a key to the swallowtail species and colour illustrations of adults, are included as online Supplementary Information.     

Biomimetic fluorapatite films for conservation of historic calcareous stones

Fluorapatite protective films were prepared on marble substrates using a biomimetic method. By mimicking the mineralization mechanism of enamel, phosphorus and fluorine were introduced on the surface of the marble substrate. In the presence of a biological template, namely collagen, an integrated fluorapatite film was produced and the marble substrate was entirely covered. The prepared fluorapatite films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive X-ray (EDX) spectroscopy. The performances of the fluorapatite films were evaluated by color changes, capillary water absorption, and acid resistance tests. The results revealed that the fluorapatite films had good compatibility with the marble substrate; the physical properties such as color and capillary water adsorption of the marble substrates were unchanged. The fluorapatite films also had good acid resistance and were stable even in heavy acid rain.     

生态人格培育与渝东北生态涵养的发展

党的十八大提出了生态文明工程建设的重要性和紧迫性，强调把生态文明建设纳入现代化建设总体布局，并高度重视三峡库区的生态环境建设。渝东北作为生态涵养发展核心区，对三峡库区经济与生态文明和谐建设具有重要的战略地位。渝东北生态涵养发展离不开生态主体的支持，优秀的生态主体人格有助于消解人的异化以及人与自然的失衡，使生态发展体现出涵养特征。大力培育生态人格，践行渝东北涵养生态，为推动美丽库区做出重要贡献。

南阳邓州元庄乡汉代水利巨石的发现及考释

南阳作为汉代的名邑，为我们今天留下了大量的文字石刻。2003年南阳邓州汉代水利巨石的发现丰富了南阳汉代石刻文字的研究。本文通过对这批石刻文字的考释、研究，旨在让人们更多的了解南阳汉代的文化，从而全面的认识南阳。     

Ag^＋交换沸石分子筛吸附小分子的结构与电子性质的密度泛函理论研究

采用密度泛函理论研究了Ag^＋交换沸石分子筛及其吸附NO，H2O，CO，H2S和SO2的结构及电子性质，并对簇模型进行了自然键轨道（NBO）分析，用分子中的原子（AIM）理论研究了相关键的拓扑性质．研究结果表明，NO，CO和SO2的吸附导致了Ag^＋和沸石骨架上氧的距离缩短，这主要是因为NO，CO和SO2的吸引电子能力较大使Ag-O1和Ag-O2共价性增强所致；而H2O，H2S的吸附导致了Ag^＋和沸石骨架上氧的距离增大，可归因于H2O，H2S的吸引电子能力弱使Ag-O1和Ag-O2共价性减小所致．
