The eikonal equation of wave front surface and general equation of organization center were obtained. These eikonal equations reveal the wave front surfaces have structures of twisted scroll wave and Mbius band, the organization centers have structures of knotted and linked ring. These theoretical results not only explain the wave patterns of BZ(Belousov-Zhabotinskii) chemical reaction but also give several possibility structures of wave front surface and organization center in general excitable media.展开更多
Kapsel Media Center PC最让人行注目礼的地方，就是它超级可爱的造型。其身材大小只有27cm×23cm×10cm，玲珑的曲线和豌豆一和样的cute造型应该能引起大堆女生的尖叫。它可以平放，竖放或者是挂在墙上，适合不同的数字家庭装...Kapsel Media Center PC最让人行注目礼的地方，就是它超级可爱的造型。其身材大小只有27cm×23cm×10cm，玲珑的曲线和豌豆一和样的cute造型应该能引起大堆女生的尖叫。它可以平放，竖放或者是挂在墙上，适合不同的数字家庭装修环境，这台PC采用了Windews Media Center Edition操作系统，能录放音乐和视频文件，展开更多
