防伪技术

品牌保护计划和产品供应链项目的成功与否，取决于品牌供应商是否有能力满足不同客户的个性化需求。现在，造假技术已经非常高明了，假冒伪劣产品完全可以达到以假乱真的程度，人们从外包装上很难区分出假冒伪劣产品与正品的差异。采用科学方法设计的防伪包装技术能够确保药品的真实性、质量和安全性。     

整合医疗经验

在推进转译医学的进程中，生物制药研究与医疗保健诊断之间的联系将更加紧密，并从中受益良多。研究人员必须能够获得并使用大量通过临床试验和医疗实践收集的信息。特别是对于某些跨学科领域而言，例如系统生物学、生物标记研究和个，性化用药方面，这些信息更是必不可少的。     

Vertical Load-Deflection Behaviour of a Pneumatic Tire Subjected to Slip and Camber Angles

In this paper the vertical load-deflection behaviour of a pneumatic tire has been studied theoretically. A simple mathematical model which is especially suitable for a tire applied by a side force has been developed. Researches carried out in the past show that the tire vertical stiffness varies neither proportionally nor symmetrically as the slip angle of a cambered tire is changed. This effect can be explained by the theory developed here.

The model predictions have been verified using experimental results obtained from literature. Moreover, tire cornering characteristic curves obtained under different test conditions, i. e. during increasing of the slip angle the vertical load is kept constant or not, have been discussed through a simulation example. This study shows that the characteristic curves vary rather considerably under the different conditions.     

德国城市轨道交通的各种制式系统

鉴于中国的城市轨道交通建设已进入了加速发展的大好时期,但由于地铁项目投资巨大,工期长,而且运营、维护成本也很高,地铁不可能满足中国所有城市轨道交通发展的需求,故而必然会转向采用投资较少的其他轨道交通制式.为此,介绍了欧洲大都市轨道交通系统的主要特征,重点阐述了德国城市轨道交通的各种制式系统,包括区域线、市域线、地铁、轻轨等现代城市轨道交通的各方面情况,以供中国同行参考.
