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.

Since 1999, the Russian economy has witnessed a rapid growth. However, the Russian government did not take advantage of this favorable opportunity to carry out industrial restructuring, but rather adopting a "passive adaptation" policy, which results in Russia's dual industrial structure today. On the one hand, Russia's total industrial structure has undergone positive changes, not only there has been preprimary adjustment in the relationship between the three industries, but there is a high-level trend in the industrial structure; on the other hand, the internal structure of Russian industry seems to become more unreasonable, even somewhat backwards.

在1999年以来俄罗斯经济的迅速攀升中，俄政府没有利用这一有利时机进行产业结构调整，而是采取"消极适应"的政策，于是出现了今天俄罗斯产业结构的双元现象：一方面，俄罗斯总的产业结构发生了积极的变化，不仅三次产业的关系得到了初步的调整，而且产业结构出现了走向高级化的趋势；另一方面，俄罗斯各产业内部的结构愈发不合理，甚至呈现倒退的态势。
