The impact and solidification processes of single melting tin dust at the micron scale on a spherical bead were numerically studied with hot flue gas flow. The geometrical evolution of dust impacting on hot bead and spreading without solidification involved initial spreading, retraction and oscillation, and stabilizing. The increased impact angle was found to reduce maximum spread area, weaken retraction and oscillation, and raise steady spread area. Dust impacting on cold bead completely solidified after liquid spreading and solidification without retraction and oscillation. Increased impact angle raised solidification sliding distance, whereas it reduced solidification spread area. Then, the effects of bead temperature, dust inlet velocity and size on the sliding and spreading of dust were studied, and the results indicated that increasing bead temperature, dust inlet velocity and size could raise solidification sliding distance and solidification spread area. With the dusts continually impacting on the bed, a dust layer forms at the front of bead, being different from that of solid dust, which becomes thick firstly, and then spreads from bead front to sides.

以乳清蛋白和果胶、葡聚糖为主要原料,采用酸诱导法制备乳清蛋白-果胶乳液凝胶(whey protein-pectin emulsion gel,WP)和乳清蛋白-葡聚糖乳液凝胶(whey protein-glucan emulsion gel,WG),比较35%、75%分散相体积分数凝胶(分别记为WP35、WG35、WP75、WG75)的功能特性,并进一步探究高内相乳液凝胶作为脂肪替代物在低脂再制奶酪中的代脂效果。结果表明:WP75的平均粒径最小,脂肪分布均匀,蛋白质网络结构稳定。乳液凝胶样品在0.1~10 Hz内弹性模量(G′)和黏性模量(G″)都随油相体积分数的升高呈上升趋势,其中WP75抵抗形变能力、热稳定性及持水性都优于其他样品。样品15%-WP75(添加WP75,脂肪质量分数15%的再制奶酪)油析性减弱,熔化性增强,质构特性与全脂对照无明显差异。研究表明乳清蛋白与果胶制备的高内相乳液凝胶在低脂奶酪产品有较好的脂肪替代效果,在低脂乳制品加工中具有良好的应用潜力。

企业是实现“双碳”目标的行动主体,加快企业绿色转型已成为实现高质量发展和生态文明建设的重要环节。以我国近年来逐步开始实施的市场准入负面清单制度作为外生事件,选取沪深A股上市公司作为研究样本,深入考察市场准入管制放松与企业绿色转型的关系及作用机理。研究发现:市场准入管制放松可以显著促进企业绿色转型,该结论在一系列稳健性检验之后依然成立。进一步分析发现,市场准入管制放松主要通过提升资源配置效率、缓解管理层短视和推进企业数字化转型三种途径来促进企业绿色转型。与此同时,非国有企业与制造业企业中市场准入管制放松对企业绿色转型的促进作用更明显,处于西部地区与市场化程度低行业的企业,市场准入管制放松对其绿色转型的积极影响更显著。研究结果能够为进一步贯彻落实市场准入负面清单制度和推进企业绿色转型提供经验参考和理论支持。
