The composition, structure and functional properties of Agaricus blazei polysaccharide were summarized. The extraction techniques of polysaccharides and the features of different extraction methods were enumerated and compared. The problems in the research of A. blazei was discussed， such as unsystematic basic research, immature technological conditions, imperfect equipment and facilities, and low degree of specificity in seeds. In the end，the research direction of A. blazei polysaccharide was prospected.

AbstractIt is of great significance to improve the design efficiency and guide material selection for carbon fiber reinforced polymer (CFRP) vehicle structures, thereby, contributing to lightweight high-speed trains. This study proposes a material-structure integrated design approach that bridges the computational relationship between design variables across multiple scales and the impact responses of CFRP vehicle structures. Computational models are constructed at the micro-scale, meso-scale, and macro-scale to capture the multi-scale characteristics of the CFRP structures. At micro-scale, finite element simulations are used to determine the effective properties of fiber bundles using a representative volume element (RVE) model. This information is then transferred to the meso-scale RVE model to calculate the homogenized mechanical properties of the lamina. Finally, a macro-scale model is established to investigate the damage mechanisms and impact resistance of the CFRP apron board against the projectile impact. The influences of design variables, such as fiber type and volume fraction, are analyzed to provide further insights into the design of CFRP apron boards. [ABSTRACT FROM AUTHOR]

Based on analysis of training resource demand of coal mine enterprise, features of cloud resource service platform for coal mine training were described, structure of the platform was designed, design methods of resource management layer and application service layer of the platform were proposed, and operating mechanism of the platform which combining modes of council, membership and corporation was introduced. The platform can provide abundant coal mine training resource for coal mine enterprise, and enhance resource sharing and information exchange among coal mine enterprises.

In view of the research results of enriched product types and improved flavor characteristics and health care functions by applying probiotic fermentation technology in deep processing of fruit and vegetable juice, this paper summarized the influence of probiotic fermentation on physical and chemical properties of fruit and vegetable juice, the probiotic activity maintaining technology and probiotic function of fermented fruit and vegetable juice. It was pointed out that: probiotic fermentation could not only change the flavor and sensory quality of fruit and vegetable juice, but also changed the chemical components of organic acids and polyphenols in fruit and vegetable juice; the number of viable bacteria in probiotic fermented fruit and vegetable juice could be increased by adding auxiliary prebiotics, embedding microcapsules and optimizing fermentation conditions; fermented fruit and vegetable juice had probiotic functions such as raising gastrointestinal function, resisting oxidation, inhibiting bacteria and elevating type II diabetes. At present, the research on fermented fruit and vegetable juice was still in the laboratory research stage, and has not been put into the factory for mass production. In the future, in-depth research can be carried out on screening suitable fermentation strains, enhancing the survival rate of probiotics in fermented fruit and vegetable juice during storage, and studying the mechanism of the relationship between fermented fruit and vegetable juice and human digestive tract health and immune regulation, so as to further promote the functional development and industrial production of probiotic fermented fruit and vegetable juice.
