stress buffer meaning in English

应力缓冲器

However , the performance of thermoelectric materials can be optimized if various materials with different properties are arranged along the temperature axis to form a graded or laminated thermoelectric material . in the present work some homogeneous materials such as bi2te3 - and fesi2 - based thermoelectric materials as well as pseudo - binary alloys ( pbte ) 1 - x ( snte ) x ( 0 x 1 ) have been prepared , their thermoelectric properties have been measured , and the possibilities for constitution of laminated structures have been discussed . the processes for preparation of laminated thermoelectric materials and the thermal stress buffer layers sandwiched between thermoelectric material segments have been studied
本项工作主要包括： 1 )均质热电材料bi _ 2te _ 3基、 fesi _ 2基以及膺两元合金( pbte ) _ ( 1 - x ) ( snte ) _ x ( 0 x 1 )的制备与性能研究，适合于制作梯度功能材料的各种均质热电材料的筛选； 2 )异种材质及近乎相同材质叠层材料制备工艺的研究以及热应力缓和层的研究) ； 3 )采用sem 、 edax 、 empa 、 xps等多种手段，对界面处微观组织结构、扩散与反应的分析； 4 )采用数学建模计算及实验测量，对两元和多元叠层热电材料的结构设计以及性能和热稳定性的研究。
