Various data were utilized to analyze the sedimentary facies,completely reconstruct the palaeogeographic maps,and evaluate the reservoir quality of the Middle-Upper Cambrian Xixiangchi Formation in the Sichuan Basin,including evidence from field outcrops,drilling cores,microscopic thin sections,scanning electron microscopy （SEM）,combined with experimental analysis data,such as petrophysical data(porosity （%） and permeability （mD）),and radioactive elements (uranium (238U),thorium (232Th),and potassium (40K)),and isotopic data (δ13C)).In the Sichuan Basin,the Middle-Upper Cambrian Xixiangchi Formation was principally deposited in a restricted platform with a lithology predominantly composed of dolomite,with local occurrences of limestone and other rock types in small *** beddings,cross beddings,horizontal beddings,storm depositions,and mud cracks locally developed in some *** 3rd-order sequences （SQ1-SQ4） were identified within the Xixiangchi Formation in this *** sequence is subdivided into a highstand systems tract （HST） and a transgressive systems tract （TST）.Reservoirs are principally developed in high-energy grain shoal deposits located in SQ2 and SQ3,with a minor occurrence in SQ1 and *** lithology of these shoal deposits is essentially composed of sandy dolomite and crystalline dolomite characterized by relatively low average porosity （2.61%） and permeability （1.0073 mD） *** increase of these values in several studied samples might be related to seepage and connecting dissolution pores and vugs through fractures which have a constructive effect on porosity and *** occurrence of karst caves through superimposed supergene karstification and bedding karstification highly improved the reservoir's physical properties in some *** reservoir space is dominated by intergranular dissolution pores,karst caves,and fractures,and their formation was controlled by sedimentation,diagenesis,penecontemporaneous dissolu

城市热岛在一定程度上会给城市发展与人类生活带来影响。我国东部季风区夏季常受西太平洋副热带高压(副高)的影响,副高控制下的区域气流下沉,地表热量难以扩散,城市热岛效应加剧明显。目前,国内外有关副高与城市热岛的研究文献不多,副高对城市热岛的作用机理、昼夜差别等尚不清楚。划分了不同城市规模等级和有无副高两种条件,用城乡二分法提取乡村背景,利用MODIS卫星的地表温度数据计算了2013—2022年7月的长江中下游地区各规模城市的热岛强度和空间热岛比例指数(UHPI),用地理探测器分析各类影响因素,以探讨长江中下游地区不同规模城市有无副高控制时的热岛特征。得到以下结论:(1)白天热岛分布空间差异大,强热岛显著分布在大城市中心,夜晚弱热岛分布面积广泛。副高控制时昼夜热岛强度高值分布在大城市,无副高控制昼夜热岛强度高值在中等城市和小城市中。(2)夜晚各规模等级城市UHPI均值高于白天,副高控制年月的夜晚UHPI均值普遍高于无副高控制年月。超大城市和特大城市的昼夜UHPI值普遍高于其他规模城市,两类小城市夜晚UHPI值高于中等城市和Ⅱ型大城市。(3)地表特征对夜晚热岛的影响显著,副高控制下的主要因子为建筑指数,无副高控制则是植被指数。影响白天热岛强度的空气质量因子是臭氧和空气质量指数,夜晚热岛的影响因子则是气溶胶。昼夜热岛强度的重要影响因子为夜间灯光和人口密度这两项社会活动因子和距离副高主体远近这类气象因子。

为提高小曲白酒中乙酸乙酯的含量,以大曲中分离的一株产酯能力较强的扣囊复膜酵母M1为出发菌株,将其制备为麸曲(M1麸曲)并用于小曲白酒酿造,分析M1麸曲强化发酵对小曲白酒挥发性风味组分的影响。结果表明:M1麸曲最佳培养条件为:水分质量分数40%、培养温度28℃、麸皮初始酸度6 mmol/100 g、培养时间48 h;酿造实验结果显示,添加M1麸曲显著提高了实验组(K组)乙酸和乙酸乙酯的含量(P<0.05),极显著降低了异丁醇和异戊醇的含量(P<0.01);通过对微生物群落结构的分析表明,对照组和K组酒醅的微生物群落演替规律存在差异,K组扣囊复膜酵母属和魏斯氏菌属相对丰度增加;同时通过PICRUSt2功能预测分析,验证了K组参与乙酸和乙酸乙酯代谢的酶丰度更高。通过麸曲为介质将扣囊复膜酵母M1应用到小曲发酵可有效提高小曲白酒乙酸乙酯的含量,对提高小曲白酒质量具有一定参考意义。

A PARTIAL ROBUST OPTIMIZATION APPROACH TO INVENTORY MANAGEMENT FOR THE OFFLINE-TO-ONLINE PROBLEM UNDER DIFFERENT SELLING PRICES

引用

Journal of Systems Science and Systems Engineering 2017年第6期26卷 774-803页

作者： Hui Yu jie deng 1.School of Economics and Business Administration Chongqing University Chongqing 400030 China

This study examines an optimal inventory strategy when a retailer markets a product at different selling prices through a dual-channel supply chain, comprising an online channel and an offiine channel. Using the operating pattern of the offiine-to-online （020） business model, we develop a partial robust optimization （PRO） model. Then, we provide a closed-form solution when only the mean and standard deviation of the online channel demand distribution is known and the offiine channel demand follows a uniform distribution （partial robust）. Specifically, owing to the good structural properties of the solution, we obtain a heuristic ordering formula for the general distribution case （i.e., the offiine channel demand follows a general distribution）. In addition, a series of numerical experiments prove the rationality of our conjecture. Moreover, after comparing our solution with other possible policies, we conclude that the PRO approach improves the performance of incorporating the internet into an existing supply chain and, thus, is able to adjust the level of conservativeness of the solution. Finally, in a degenerated situation, we compare our PRO approach with a combination of information approach. The results show that the PRO approach has more ＂robust＂ performance. As a result, a reasonable trade-off between robustness and performance is achieved.

Modeling and experiments of a nano-positioning and high frequency scanning piezoelectric platform based on function module actuator

引用

Science China(Technological Sciences) 2020年第12期63卷 2541-2552页

作者： deng jie LIU YingXiang ZHANG ShiJing LIU JunKao School of Mechatronics and Engineering Harbin Institute of TechnologyHarbin 150001China

A piezoelectric platform using function module actuator is presented to achieve nano-positioning and high frequency scanning in large working range. A function module actuator is designed to produce a pair of orthogonal bending deformations and a longitudinal deformation through partition exciting. The bending deformations are used to actuate the planar motion,while the longitudinal deformation is utilized to dynamically adjust the driving force and broaden the scanning frequency. The dynamic model of the platform system is developed. The open-loop performances of a prototype are first tested: a scan frequency of 308 Hz in a scanning range of 3.368 μm×3.396 μm is measured in direct actuation mode,and the displacement resolution is measured to be 16 nm;maximum speed is measured to be 3.38 mm s^-1 in the inertial actuation mode. Furthermore,the closedloop experiments are carried out and a switching strategy is proposed to obtain the switching of the inertial and direct actuation modes automatically;the platform achieves the scanning with frequency of 300 Hz at the set position.
