    摘要： A hydrocarbon feedstock is catalytically reformed in a process which comprises contacting the feedstock in an initial catalyst zone with a catalyst comprising platinum, germanium and halogen on a solid catalyst support. The product from the first catalyst zone is contacted in a terminal catalyst zone with a catalyst having the essential absence of germanium and comprising platinum, halogen and a metal promoter on a solid catalyst support.

    摘要： A process for removing sulfur oxides from a gas by contacting the gas with an acceptor comprising a lithium doped mixture of magnesium and aluminum oxides. The acceptor reacts with and retains the sulfur oxides. The retained sulfur oxides are then removed from the acceptor by reducing the acceptor through contact with hydrogen. The above process has the advantage of extremely high selectivity for hydrogen sulfide with regard to the effluent produced during the reduction step.

    摘要： A method for forming a surface-relief grating with a desired spatial variation of duty cycle in a layer of photoresist includes: providing a first mask bearing a high-resolution grating of linear features, arranging the first mask at a first distance from a substrate, providing a second mask bearing a variable-transmission grating of opaque and transparent linear features that has a designed spatial variation of duty cycle, arranging the second mask at a distance before the first mask such that the linear features of the variable-transmission grating are orthogonal to the linear features of the high-resolution grating, illuminating the second mask while varying the first distance according to displacement Talbot lithography and also displacing the second mask at an angle to its linear features such that there is substantially no component of modulation with the period of the variable-transmission grating in the energy density distribution that exposes the photoresist.

    摘要： The invention relates to a method for determining the amount of oat flour addition in compound flours and noodles, and it belongs to the field of food detection technology. Based on the similarity of the fatty acid composition between oat and wheat, the quantitative analysis index used for measuring the oat flour addition was determined. Based on the differences of fatty acid contents in oat and wheat, the relationship between the changing trend of fatty acid composition and oat flour content in compound powders or noodles is employed to quantitatively determine the amount of oat added to these compound flours or noodles. The invention provides a highly sensitive and feasible method for safety monitoring and quality control of oat flours and oat noodles.

    摘要翻译： 本发明涉及一种用于测定复合面粉和面条中燕麦粉添加量的方法，属于食品检测技术领域。 基于燕麦和小麦之间的脂肪酸组成的相似性，确定了用于测量燕麦粉添加量的定量分析指标。 基于燕麦和小麦中脂肪酸含量的差异，采用复合粉末或面条中脂肪酸组成变化趋势与燕麦面粉含量之间的关系来定量确定添加到这些复合面粉或面条中的燕麦的量。 本发明提供了一种用于燕麦面粉和燕麦面条的安全监测和质量控制的高灵敏度和可行的方法。
