The authors suggest that games do not install the mouse driver mouse dpi does not need to be reduced to 400-800, just under the windows in the windows mouse speed slider down to No. 3 Georgia, plastic mouse pad of generally 1-3 between the more appropriate because the plastic mouse pad surface is very slippery faster mouse speed setting will feel the mouse is floating, cloth pad in about 3-4 on the same subject.

笔者建议游戏鼠标不要安装鼠标驱动程序也不需要把 dpi 调低至400-800，只需要在 windows 下把 windows 鼠标速度滑块拉到第3格即可，，塑料鼠标垫一般在1-3之间较为合适，因为塑料鼠标垫表面非常滑鼠标速度设定快了会感觉鼠标很飘，布垫在3-4左右就差不多了。

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.
