The results show that the reverse martensitic transformation start temperature increases with the increase of prestrain, which may be due to the elastic energy released by prestrain, and the energy dissipated increased by plastic deformation and the constrain effects of grains.

结果表明，逆相变开始温度随预应变增加而增大，其原因是预应变造成马氏体再取向使弹性能降低，引起的塑性变形和晶粒间的约束提高了耗散能。

Firstly, the high resolution pictures of dragonfly wings from sample tests were studied thoroughly, and the unique feature of the reticulate vein distribution and the variation of the vein sizes and the grid shapes in different zones were figured out;then several computational models based on a dragonfly wing were established by using ANSYS, and beam 189 and shell 93 elements were used respectively in modeling of the veins and the membrane so as to ensure the compatibility between the veins and the membrane at a deformed state;these models subject to uniform loading cases were analyzed respectively so as to explore the unique performances of the wing structure, furthermore, through eigenvalue spectrum analyses of these models, the special role of the pterostigma in eliminating or suppressing the wing quivering effect was also evaluated.
