结合爆轰物理学和材料学的有关理论,对弹药群爆时弹丸壳体的塑性膨胀变形过程进行了分析,建立了弹药群爆条件下的弹丸壳体运动速度的动力学算法,计算出了弹丸壳体膨胀破裂时的半径和形成破片的初速。     

Consumer preferences and physical evaluation of shortbread stored in different packaging

The work aimed to assess the quality of crackers and sponge, vanilla and butter biscuits stored for 28 days in an original packaging, plastic box (Polypropylene 0.2 mm), food film (HDPE 10 mm) and paper bag. Sensory tests did not prove influence of packaging on the product quality. The authors observed: water desorption for sponge biscuits (ca. 5%), water absorption of 0.06%–1.84% for other biscuits, hardness increase of 20% ÷ 40% for sponge biscuits, hardness decrease by 10% ÷ 23% for vanilla biscuits, hardness increase for crackers in original packaging (+46%) and paper bag (+20%), hardness decrease for samples in food film (‐ 8%) and plastic box (?26%), hardness change for butter biscuits (from +9% to ?15%). Complex assessment proved that HDPE film and PP box most effectively protected the product against the environmental influence. Lengthening the biscuit lifetime requires introduction of innovations regarding the manufacturing technology and packaging design/structure. Presented tests indicate both the advantages and disadvantages of typical packaging, seen from the consumer perspective. It must be remembered that “manufacturer”—“consumer requirements” relation is one of the most important stages of product assessment and development. The authors believe that the obtained results are useful for packaging producers that are new on the market, but also for those which are experienced.

弹药产品反求设计分析

文章针对当今世界弹药产品迅猛发展、发达国家先进武器不断商品化的现状,一般性地分析了弹药产品反求设计的前提——国际环境、学科基础,并从一般特点、设计原则、基本步骤、反求方法等几方面对弹药产品反求设计进行了分析,提出了弹药产品反求设计的目的——再创造、科学反求。     

论包装的视觉营销功能与个性化

包装作为产品整体概念的一个组成部分,是品牌理念、产品特性、消费心理的综合反映,它直接影响到消费者的购买欲,是建立产品与消费者亲和力的有力手段。包装作为视觉营销策略的重要组成部分,具有视觉传达功能、市场定位功能、传递文化功能。包装的设计应具有个性化,符合、满足消费者的心理,有利于促进商品的销售。

Twisting Tradition: Consumers' Behavior Toward Alternative Closures

Consumer evaluations of products are not entirely based on the absolute attributes or value of the product, but rather on the discrepancy between the product's attributes and the expectations consumers have for that product. Following the Dowling and Staelin model on perceived risk, an evaluation was made of how alternative product closures interplay with consumers' situational use, subjective knowledge, level of self-confidence, and gender to influence the purchase decision.

The results provide support for the importance of such factors as situational use, the consumer's gender, level of self-confidence, and subjective knowledge, and how the style of closure affects the purchase decision. Managerial implications of the findings are mentioned.     

基于建设美丽中国视角的绿色包装设计研究

美丽中国建设要在绿色发展、循环发展、低碳发展的大趋势下逐渐展开,其中绿色发展的重要内容之一是绿色包装设计。绿色包装设计对于建设美丽中国来说是重要的构成要素。基于低碳经济的绿色包装设计致力于实现包装材料的生产过程中的低碳化,尽量选用清洁生产机制生产出包装材料。基于循环经济的绿色包装设计试图在包装过程中贯彻可持续发展原则。基于生命周期评价的绿色包装设计基于包装产品的全生命过程的测量与优化而逐步实现绿色化进程。基于技术与原则的绿色包装设计立足于技术标准与原则设立,进而在现实层面贯彻绿色理念。基于美学原理的绿色包装设计整合美学理念于绿色包装之中,为美丽中国增加美的成分。     

分子筛改性LDPE活性包装膜在草莓保鲜中的应用研究

新鲜草莓易腐烂,贮藏保鲜较为困难。为了延长草莓的贮藏期,本研究采用硅铝分子筛对低密度聚乙烯（LDPE）进行改性,制备了具有高透气性的改性LDPE包装膜。以LDPE膜包装的草莓和裸放草莓为实验对照组,在（5±1）℃的低温和加乙烯吸附药包的条件下,分别研究了LDPE和改性LDPE包装膜对草莓储存期的影响。实验中分别测定了草莓果肉中可溶性固形物含量、维生素C含量以及草莓的失重率、硬度、烂果率等指标。实验结果表明：对照组中裸放和用LDPE膜包装的草莓储藏期分别为3天和7天,而分子筛改性LDPE膜加乙烯吸附剂包装能够将草莓的贮藏期延长至11天,草莓的好果率、硬度和可溶性固形物含量等均明显高于对照组。该分子筛改性LDPE膜加乙烯吸附剂的综合包装方案能够有效延长草莓的低温贮藏保鲜时间。     

一种提升卷烟包装箱回收合格率的方法——以遵义烟草为例

为了减少烟草商业企业卷烟物流配送中心件烟包装箱的破损,提升卷烟包装箱的回收合格率,通过对物流配送中心作业过程中烟箱循环各关键环节分析,发现拆、叠烟机设备造成包装箱的破损,提出了一种增大面积法,对拆、叠压机进行升级改造,减少了包装箱的破损,从而提升了卷烟包装箱的回收合格率。结果表明通过此方法,卷烟包装箱回收合格率同比提升了12.46%。
