文中依据固体经验电子理论［１］，建立了ＮｉＴｉ形状记忆合金马氏体晶胞的键络模型；并就合金化元素Ｖ对其相变点ＭＳ的影响进行了电子结构分析，为揭示该功能材料中成分－性能－结构之间的内在联系做了初步探索，从电子结构的层次上初步解释了Ｖ对ＮｉＴｉ合金ＭＳ点的作用机制。
In this paper, based on solid empirical electronic theory [1], NiTi shape memory alloy martensite lattice key model was established; and the alloying element V on its phase transition point MS electronic structure analysis, in order to reveal the function Materials in the composition - performance - the inherent relationship between the structure made a preliminary exploration, from the electronic structure of the level of preliminary interpretation of V NiTi alloy MS point mechanism.
