对界面设计评估方式的探讨

评估者经常用3到4种方式对一个项目进行测定，这很费时间，并且偏见仍然可能存在。专家可能误导评估过程，因为没有绝对的标准，所以，新的研究提出了这样一个方法，能有效地控制个人偏爱，而且不费时间。这个方法建立在令人满意、效果显著、效率高的基础上，并且符合ISO的相关规定。不同的评估方法因为评估元素的不同而改变。研究从寻找在评测过程中容易被评估者误导的数据开始，同时研究节省时间的方式。传统的数据方式存在着一定缺陷，很难为精确的设计工作提供数据，因为，设计师对分析与运用的转换关注的很少。因此，这个实验的目的就是全面界面运用模式。

Investigation of Mechanical Properties of Friction Stir Spot Welded Light Metal Alloys

The use of light metals today is of great importance,for example in the automotive,aviation and aerospace industries,where energy consumption is minimized and thus the economy is being attempted.By using light metals,weight is reduced so that energy is saved.Aluminum and magnesium alloys are particularly used thanks to their lightweight.Vehicles in the automotive,aerospace and space industries are expected not only to have lightweight but also high static and dynamic strengths since they are exposed to static and dynamic cyclic loads.However,the structural components can quickly become fatigued and fail under cyclic load due to the notch factor of the joining zones.Compared to the fusion welding method,joining of material is realized mechanically below the melting point of the material in the friction stir spot welding(FSSW)method.Thus,the fatigue strength of the assembly is much higher than that of the fusion welding.In this study,light metal alloy of magnesium AZ31B and aluminum EN AW 2024 were joined with FSSW method and mechanical properties of this joins were also carried out.

产品设计事务所的构成类型

产品设计事务所的产生，是设计发展的必然产物，文章阐述了产品设计事务所的集中构成方式，如：集中型，分歧型，混血型，以及各种方式的优略点。从而提出，每个产品设计事务所都该有自己的定位，自己的特色。
