  • 简介:合金(SMA)电线增强了的形状存储器的机械行为疼痛有损坏的结构通过变化原则被分析,为中央排水量域的为结构的一个管理方程被导出的、数学表达式,有损坏的典型元素的压力紧张地被介绍,并且为在SMA电线和矩阵之间的接口失败的一个失败标准在死了负担的二种使活动和温度下面被建立,在温度在有效免费恢复被包括的地方,拉紧。另外,在象接口性质那样的失败标准有一些另外的创作因素,SMA的动态性质,起始的debonding长度L-l等等。结果是重要的理解自我改编的控制和SMA电线的失败机制增强了的结构的力量有损坏的聪明的结构。

  • 简介:. He used a similar unit in Anglo-American culture for replacement. 1furlong≈201m,we can translate the words literally and then add a note. In versions that aim to introduce Chinese culture,while semantic translation is added to render some culture in Chinese poetry. But no matter which method a translator adopts
