9Lunar surface mineralogy using hyperspectral data: Implications for primordial crust in the Earth-Moon system显示文摘Mineralogy of the Lunar surface provides important clues for understanding the composition and evolution of the primordial crust in the Earth-Moon system.The primary rock forming minerals on the Moon such as pyroxene,olivine and plagioclase are potential tools to evaluate the Lunar Magma Ocean(LMO) hypothesis.Here we use the data from Moon Mineralogy Mapper(M^3) onboard the Chandrayaan-1 project of India,which provides Visible/Near Infra Red(NIR) spectral data(hyperspectral data) of the Lunar surface to gain insights on the surface mineralogy.Band shaping and spectral profiling methods are used for identifying minerals in five sites:the Moscoviense basin,Orientate basin,Apollo basin,Wegener crater-highland,and Hertzsprung basin.The common presence of plagioclase in these sites is in conformity with the anorthositic composition of the Lunar crust.Pyroxenes,olivine and Fe-Mg-spinel from the sample sites indicate the presence of gabbroic and basaltic components.The compositional difference in pyroxenes suggests magmatic differentiation on the Lunar surface.Olivine contains OH/H_2O band,indicating hydrous phase in the primordial magmas.V.

10超声波辅助制革生产植物鞣制中的扩散过程显示文摘植物鞣制是一种使用天然材料并使皮革具有多种功能的鞣制方法。这种鞣制方法的缺点在于植物鞣剂(VTA)穿透皮基体需要很长时间。因此,有必要通过应用超声波等手段使这种传统的生态友好鞣制方法转变为制革人员喜欢的高效鞣制方法。本研究是有关超声波影响植物鞣制工艺的。研究了加工时间、超声波功率以及预鞣处理等重要过程参数对于植物鞣剂吸收率的影响。同时还研究了超声波功率对于成革收缩温度的影响。研究结果表明应用超声波能够显著加速植物鞣制过程。当应用120W~210W超声波时,植物鞣剂的吸收率约增加30%-40%。为了弄清楚超声波加速植物鞣制过程的机理,研究了预超声波处理对于基体(皮)以及鞣剂(VTA)的影响。在鞣制工序前的超声波预处理能明显降低植物鞣剂的尺寸从而促进鞣剂的渗透。从实验数据中计算得到的应用指定条件的超声波时,植物鞣剂的扩散系数(D)增加了1倍(D:2.64×10^-5cm^2/sec)。因此,在植物鞣制过程中应用超声波能够改进扩散速率从而明显节省加工时间并提高成革质量。这种鞣制方法能够方便地在常规划槽或鞣制系统中实现大规模加工。因此,这种新技术在不久的将来是可行的。V.

11减少制革过程中总可溶固形物的改进技术显示文摘制革加工过程中产生的总可溶固形物(TDS)约有35%来自于浸酸工序,解决TDS处理难度问题,工厂工艺的革新是必需的。本文研究了两种方法,即浸酸废液循环再利用法及不浸酸铝铬结合鞣法。浸酸废液循环再利用法通过添加恰当的化工材料可使首批浸酸液用于随后的浸酸操作;而不浸酸铝铬结合鞣法使用明矾来降低溶液的pH值以取代传统浸酸方法。因此,浸酸液循环再利用法及不浸酸铝铬结合鞣法可用于克服废液中的TDS及铬带来的污染问题,同时还可获得经济回报。V.
