摘要： 目的开发一种具有双重防伪功能的双开式聚对苯二甲酸乙二醇酯(PET)光栅包装结构,并研究其在运输振动、耐压堆码、垂直跌落翻滚过程中的安全性能。方法以PET光栅为盒体材料,通过双重防伪结构模切和内贴兑奖防伪码,采用模拟运输振动、抗压堆码及水平垂直跌落翻滚的方式进行安全性能试验,并对包装的正弦振动、抗压强度、跌落速度变化量进行分析验证。结果对此包装在开启防伪结构、抗冲击力等方面进行了优化设计,整体包装件达到安全性能的要求,在一定程度上提升了包装安全防伪水平及消费者开启体验感等。结论该包装通过双重撕裂开启结构,达到包装不可循环使用、防伪标识可兑奖等功能,具有极强的防伪功能和保护作用。

摘要： 工程师点评实际上,每个品牌都知道,如果没有足够的产业链话语权和消费控场力,在多个产品线全面铺开是一件非常不明智的事,负担和收益成正比。可像vivo这样的品牌,这两年把产品做成了触及整个扁平化市场的标杆,足见“老炮”的确很懂用户心理。这么说太笼统?那我们说细一点。如开篇点题,强调设计美学和强调自拍美学的vivo S5是vivo一次非常聪明的创作(显然,菱形主摄布局仅是一处灵感标识而非它的全部意义),它不需要所谓“跑分党”或者“参数控”去品头论足,因为它的目标群体并非他们。

摘要： 介绍了一种将沸石转轮与催化氧化技术协同组合并用于挥发性有机化合物(VOCs)废气治理的装置。通过对包装印刷行业所排放的VOCs废气风量、VOCs成分及其质量浓度与特性的研究,结合实际案例分析,发现采用疏水性分子筛的沸石转轮与催化氧化组合装置具有高去除率与高经济性效果。某生产线所排放的废气风量约为15000m^3/h(标准状态),质量浓度为53.03mg/m^3,符合大风量低质量浓度的特性。治理后,废气中的苯、甲苯、二甲苯、非甲烷烃(NMHC)的去除效率可达98%以上。对装置运行能源的计算对比表明,在催化氧化工段,液化天然气(LNG)是最经济的能源。

关键词： 消费心理学   慕课   SPOC   翻转课堂  

摘要： 消费心理学是心理学的一个重要分支,它研究消费者在消费活动中的心理现象和行为规律,内容复杂,概念抽象。传统的教学方法已难以引起学生兴趣,教学效果不佳。随着网络技术的发展,慕课(MOOC)即大规模开放网络课程应运而生。山东商业职业技术学院消费心理学的课程改革就是基于MOOC转型的SPOC结合翻转课堂的混合式教学。SPOC将MOOC引入传统校园课堂,采用MOOC的讲座视频或在线评价等功能辅助学生线上自学,同时课堂引导学生讨论延伸,即采用“翻转课堂”形式,实现MOOC与校园课堂教学的有机融合,充分发挥学生的自主性,提高教学质量。

关键词： anti-adhesive coating   front contact metallization   nanoimprint lithography   nickel hard stamps   solar cells  

摘要： Herein, a systematic investigation on the design and development of a cost-effective nickel hard stamp suitable for fabrication of a new front-side metallization pattern to reduce the shadow losses in solar cells is demonstrated. Finite element analysis (FEA)-based simulations indicate an optimal finger width of approximate to 20 mu m with interfinger spacing of 1000 mu m which can effectively enhance solar cell efficiency by approximate to 1% due to reduced shadow loss. The optimal grid design is further patterned by means of nanoimprint lithography (NIL) followed by an electroless deposition method. A cost-effective, electroless deposited nickel hard template is developed for NIL patterning using UV pattern transfer. To avoid the physical damages during the imprinting process and improve the durability of the NIL stamp, silane-based antiadhesive coating is used which can withstand up to 18 cycles of imprinting process. The nickel hard stamp exhibits improved hardness of 5.63 GPa and roughness of 8 nm and is used to transfer the narrow-line width patterns during the imprinting process. The proposed industry-ready technology overcomes the limitations of the existing screen printing process pertaining to the formation of high-aspect-ratio narrow line-width finger grid patterns.

关键词： magnetic field measurement   magnetic near-field probe   ultra-wideband magnetic probe  

摘要： An ultra-wideband magnetic near-field probe based on a conventional low-cost four layers of FR-4 printed circuit board is proposed in this article. It can be used to measure the magnetic near-field strength from RF magnetic sources or electronic devices for EMI conformance test. The operating frequency of the probe is from 1 GHz up to 20 GHz. The probe is constructed based on a coplanar waveguide and stripline with a short-end loop. The probe dimension is 10 mm x 25 mm x 0.6 mm. The prototype probe is electric field-shield structure and has a very high unwanted electric field suppression ratio about 17.7 dB. The probe calibration factor from the simulation agrees well with the calibration factor computed from the measurement. The average probe factor is 38.8 dBS/m and probe sensitivity is 47.4 dB mu A/m.

摘要： In the near future, Poland is going to have more and more favorable conditions for viticulture. Organic acids and polyphenols are among the most commonly analyzed compounds due to their beneficial properties for human health and their importance in the winemaking process. In this work, a new technique involving ultrasound-assisted solvent extraction of porous membrane-packed liquid samples (UASE-PMLS) was for the first time described and applied for real samples. The methodology based on UASE-PMLS for organic acids and polyphenols in wine samples was optimized and validated. Using the new technique coupled to GC-MS, organic acids and polyphenols were evaluated in Polish wine samples. Extraction solvent, extraction temperature, derivatization time and sample pH were optimized. Chemometric tools were used for data treatment. Good linearity was obtained for the concentration ranges evaluated with r values between 0.9852 and 0.9993. All parameters of method validation (intra- and inter-day precision and matrix effect) were over 80% with coefficient of variation (CV) up to 17%. Recovery was between (92.0 +/- 8.5)% and (113 +/- 16)%. Finally, green assessment was evaluated using Analytical Eco-Scale and Green Analytical Procedure Index (GAPI). The UASE-PMLS is characterized by many advantages, e.g., the extraction process is fast and easy coupled to GC-MS. Regarding other extraction techniques, the amount of used solvent is minimum, and no waste is generated. Therefore, it is an environmentally friendly technique.
