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。

Numerical tests are also conducted to investigate the microphysical effects to the mesocale convective systems. The evaporation of raindrops can strengthen the surface "cold pool" to decease the temperature of rainfall center. The condensation of vapor can lower the air pressure and increase the convergence and updraft so that the convective echo develops stronger. The melting of graupel can cool the air to restrain the convective activity. The falling of precipitation particles can increase the downdraft and induce the outflow nearly the surface. The effect of condensation is the most important among all the microphysical processes. It can change the whole structure of cloud system.

微物理过程对对流系统发展和维持有重要作用：强降水的雨滴蒸发过程会加强"冷池"效应，同时增强了雨带南侧原有的地面中尺度辐合线；凝结潜热在低层诱发了与回波相应尺度的中尺度低压，增强了辐合和上升运动，促进对流发展；霰的融化吸热通过冷却大气会不利于气压下降、气流辐合抬升等过程，降低对流不稳定能量，减缓对流发展；重力拖曳使气块冷却降温，降低对流不稳定能量，并且使低层的气压升高、气流辐散，在近地面附近产生出流，加强地面中尺度辐合线的强度。
