巴氏奶行业抢“鲜”研究

在新消费升级的背景下,人们越来越注重消费品质量和感受,乳制品消费的新鲜化和休闲化是新消费时代的发展趋势。营养鲜活、口感轻柔的巴氏奶,在我国乳制品液态奶品类中成为新的消费增长点,各大乳品企业纷纷加码低温赛道抢占市场。本文基于大量的文献研究并结合消费市场趋势,从而确定探究新消费下的巴氏奶行业问题。从巴氏奶市场发展现状入手,集合巴氏奶在国家政府部门所发布的各项利好政策为发展背景优势。通过分析巴氏奶在乳品市场中的规模,发现其增速提高和占比增大的发展态势,强劲的增长吸引各大乳品企业争先布局低温市场。为了避免盲目入局,本文继续分析了巴氏奶在目前发展中存在的问题,并对上述巴氏奶发展问题提出了针对性的建议,最后围绕新消费下的特点,重构“人货场”三要素,以期激活消费者的购买力。     

A Visco-plastic Model of Magnetorheological Materials

Magnetorheological materials are a class of smart materials whose reological properties may be rapidly varied by application of magnetic field. By a simple mechanical mold, a visco-plastic model for the materials is developed. It is shown that the model can describe the variation of the mechanical properties for the Magnetorheological materials in the different magnetic field. The result is shown that the model can characterize the mechanical properties of Magnetorheological Materials in plastic and viscous variation.     

Micromodel of Computer Emulational Simulation on Twin-roll Casting Strip Solidification Structure

Based on the research on the solidifiation of twin-roll casting strip,the analytical model and emulational model of nucleation,the growth of dendrity tip and colunar dendrity transformation to equiaxis dendrity (CET)of twin-roll casting strip solidification are established by means of the principle of metal solidification and modern computer emulational technology.The foundation for the emulational simulation of twin-roll casting strip solidification structure is laid.     

Advances in Pharmacological Studies of Coptis Chinesis

A Coptis Chinesis is the dry rhizoma of ranunculaceous Coptis Chinesis Franch or Coptis deltoidea C. 7. Cheng et Hisao, or Coptis teeta Wall. It is the traditional Chinese herb, which is used in the contagious diseases. In recent years, its new pharmacological actions have been reported, which are antitumour, hypoglycemic response, immunoloregulation, improving the functions of cardiovascular. The important pharmacological functions of Coptis Chinesis are hypoglycemic response, improving the functions of cardiovascular, antitumour. With the deeply researching of Coptis Chinesis pharmacology, and the continuous founding of pharmacological mechanism, new preparation will be widely applied in the clinic.     

Model of Financing Strategy

Considering information asymmetry between inside and outside of the firms,this paper discusses the financing strategy of M&A,and builds a model.According to the model,we can see that the firm with relatively expected low-productivity will choose equity financing for M&A,and the firm with relatively expected high-productivity will choose debt financing for M&A,and the firm with expected medium-productivity will not choose financing from outside.In the case of undeveloped capital market and financing tools in China,the conclusion of the model has some extent significance for helping firms to choose financing strategy for M&A rationally.     

Analysis on Micro-structure of TiN Thin Film and Polyimide with AFM

The study in molecular morphology is given with a highresolution Atomic Force Microscope AFM.IPC-208B.By taking TiN thim film prepared by magnerton sputtering method and polymide(PI) fibre for examples,the preferenthal growing plme of TiN thin film,the atomic arranges of TiN thin film on the preferential growing plme and the surficial micro-structure can be ascertained form the three-dimensional images obtamed by AFM.IPC-208B.These experiments not only identify small structures of the materials,but also affirm that AFM.IPC-208B holds the precision of atomic level and potential application in micro-structure field,at the same time it establishs the groundwork for the application in micro-process kingdom.     

Work-hardening Mechanism of Non-magnetic High Manganese ZG25Mn18Cr4 Castings

The important character of non-magnetic high manganese ZG25 Mn18Cr4 alloy is rapid work-hardening under external stress. With X-ray diffraction and TEM analysis, it is proved that the microstructures of both undeformed and deformed matrixes are austenite and carbide with some striation structure in the matrixes, the amount of stripes in the deformed matrix is obviously more than that in the undeformed matrix. Electronic diffraction analysis confirmed that the stripes in coarse austenite grains are high density lamination fault sheets. A great deal of lamination fault sheets produced by plastic deformation divides up austenite matrix, shortens the free distance of dislocation movement and results in the rapid work-hardening of ZG25Mn18Cr4 alloy.
