Our results indicate that not only the poloidal convection patterns in uppermost mantle have good correlations to surface tectonic motion, but also the toroidal ones reveal important information of their horizontal motion and rotation for the first time. There is a SEE_NWW strong convection zone close to the equator in toroidal convection patterns, which probably correlates with the large_scale shear zone near the equator and is the deep dynamic background of strong earthquake occurrence in this zone. The opposite rotating large_scale convection rolls in the Southern and Northern hemispheres suggest that maybe there is differential rotation between them.

研究结果表明，不但地幔浅部的极型场对流图像显示出了与大地构造运动的相关性并揭示了其深部动力学过程，更重要的是，地幔浅部的环型场对流图像首次为我们认识和理解板块构造的水平与旋转运动提供了重要的信息：环型场速度剖面中在赤道附近存在一条大致南东东—北西西向的强对流条带，可能与环赤道附近大型剪切带的形成相关，进而表明可能是该带强震发生的深部动力学背景；在南北半球存在的旋转方向相反的对流环表明它们整体上可能存在差异旋转。

The form of its locomotion is: first, drive shaft inconjunction with the knife rest going down vertically in a certaindistance, then the magnetic stepping motor works, then the gearwheel group revolving with the shaft and the knife rest. Afterrevolving a circle, the air pressure vat decompresses, then, theshaft and the knife rest resets in the result of the spring.

其运动形式是：通过气压缸将传动轴和刀架打下一个固定距离，然后步进电机开始工作，通过带轮组带动传动轴和刀架作旋转运动，旋转360度后气压缸开始减压，复位弹簧使主轴和刀架复位。
