One simplified hypothesis is that, when the growth cone detected the directional signal, actin will polymerize asymmetrically in the growth cone, so that the filopodia and lamelipodia will extend preferentially to one side, microtubule will further follow and stabilize this growing direction.

一种假说认为，当轴突生长锥探测到方向性的信号时，生长锥内的 actin成分发生不对称聚合，filopodia及lamelipodia向一侧优先延伸，进而轴突内微管也朝同侧延伸，使生长方向进一步稳定下来。

This routine insured the research work finished in limited term. Since the torque coupling increases the inertia of transmission input shaft, the conventional AMT control technology can not control shifting process well.
