In the first year (2001), the actuator ability of shape memory alloy (that is, two-way shape memory effect) was investigated fundamentally in the following way.(1) The measuring system of three-dimensional movement in the two-way shape memory movement was developed. The rozet-type strain gauge was employed for the strain measurement. The temperature control system was developed to give the cyclic temperature to the shape memory alloy.(2) The two-way shape memory effect obtained by the simple loading training (the uniaxial tension and simple torsion) was experimentally investigated by \using the Cu-based shape memory alloy tube. Moreover, the micro-structural change of the material obtained by the training were observed and analyzed from the view point of two-way shape memory mechanism.(3) The two-way shape memory effect obtained by the complex loading training was experimentally investigated by applying the combined loads of axial force and torque to the thin-walled tube specimen of Cu-based shape memory alloy.In the following year (2002), the experimental data obtained in the first year were analyzed and the actuating ability of shape memory alloy was discussed, and several additional experiments were performed. In the result, the shape memory alloy was found to be quite unique and interesting material for designing the engineering actuator.These successful results were published in several international journals.

第一年(2001年)，我们从根本上研究了形状记忆合金的执行能力(即双向形状记忆效应)。(1)开发了双向形状记忆运动中的三维运动测量系统。应变测量采用rozet型应变计。开发了温度控制系统，为形状记忆合金赋予循环温度。(2)利用铜基形状记忆合金管，对通过简单加载训练(单轴拉伸和简单扭转)获得的双向形状记忆效应进行了实验研究。并从双向形状记忆机制的角度对训练获得的材料微观结构变化进行了观察和分析。(3)通过对铜基形状记忆合金薄壁管试件施加轴向力和扭矩的联合载荷,实验研究了复合加载训练获得的双向形状记忆效应。次年(2002年)将第一年获得的实验数据 分析并讨论了形状记忆合金的驱动能力，并进行了一些额外的实验。结果发现，形状记忆合金是用于设计工程执行器的非常独特且有趣的材料。这些成功的成果发表在多个国际期刊上。
