In the investigation of Cu-Zn-Al SMA, the influence of quenching speed, shape memory thermal treatment on SME, microstructure and morphologies was discussed. The changes in morphology and interfaces were in situ metallographic observed during thermal cyclings in order to control the degradation of two way shape memory effect . The stabilization of stress induced martensite variants method and the accordingly changes in microstructure were studied in detail. The mechanism was also compared between SSIM and TWME training method. From the above in situ observation results, the interface structure and especially the twin related A: B type variant pair were examined by HREM to clarify the role of movability of interfaces and the changes in variants orientation in inducing the degradation of the TWME. During developing the Ni-Ti-Hf SMA melt spinning ribbon, it was found the morphology and structure embodied the SME and was directly effected by chemical composition and technique factors, such as the different content of Hf, the speed of copper roller rotation and etc. Therefore, the morphology and structure were extensively examined.

在对Cu-Zn-Al形状记忆合金研究中，研究了提高记忆效应的热处理淬火速度、记忆热处理方式对Cu-Zn-Al形状记忆合金组织结构的影响；为了弄清双程记忆效应衰减的原因，原位动态观察了热循环过程中，合金组织形貌及界面的变化；因形状记忆合金必须经记忆训练才能具有双程记忆效应，系统地研究了应力诱发马氏体稳定化训练方法和这种方法引起的双程记忆合金组织结构的变化，比较了它与双程记忆效应训练方法诱发TWME机制的异同；因在原位动态观察中发现界面可动性及两侧变体取向的变化，伴随着记忆效应的衰减，用HREM详细研究了变体的界面结构，特别是A：B型变体界面结构及变体内部结构。

The results showed that the content of Se element in the Se-MT was 2.5 folds higher than that of Zn-MT, on the contrary the content of sulfur element in Se-MT was 2 folds lower then Zn-MT, C, H, N contents in MT were no significant differences in both groups. In terms of chemical property, the element of selenium is very similar to sulfur because they are in the same group in the periodic table. The above results illustrated that the Se could replace S from SH-sulfhydryl to SeH-selenihydryl in cysteine, which presents the existence of a novel Se-MT.

结果表明Se－MT中Se元素含量高于Zn－MTZ.5倍左右，而 S元素含量低于 ZnMT 2倍左右，C、H、N元素含量无明显差异，这说明了麦硒康诱导后Se仙T分子结构上的差异，由于Se元素与S元素同属氧族元素，在化学性质上极为相似，故Se元素极可能替代了MT的合成过程中所必需半味氨酸残基中的SH一基因上的S元素成为SeH一基团，这样我们就得到了一种含SeH一基团的新型Se－MT。

The results showed that loading Ag^＋, Ni^2＋, Cu^2＋ or Zn^2＋ ion on the activated carbon obviously improved its adsorption of benzothiophene, while loading Fe^3＋ or Co^3＋ ion on the activated carbon caused a decrease in its adsorption of benzothiophene in comparison with the original unloaded activated carbon, which was due to the variation of the nature of soft and hard acid on the surface of the activated carbon.

采用密度泛函数理论法计算结果表明，苯并噻吩的电负性χ为2.638，属软碱类物质；由于Ag^＋为软酸，活性炭负载Ag^＋离子，增加了其局部表面的软酸，从而增强了对苯并噻吩硫化物的吸附；由于Ni^2＋、Cu^2＋和Zn^2＋离子属交界酸，负载Ni^2＋、Cu^2＋、Zn^2＋离子增加了活性炭表面的交界酸，也在一定程度上提高了其表面对苯并噻吩硫化物的吸附；当活性炭表面负载了硬酸性Fe^3＋或Co^3＋离子，其局部表面硬酸增大从而降低了其对苯并噻吩的吸附。
