Thus we need to design locking loop of DTG on moving base which can loop DTG nearby the zero deflection angle during the whole course from starting to working to stopping .

因此，必须设计动力调谐陀螺仪的动基座锁定回路，将陀螺仪在陀螺电机从加电至完全停止的全过程中锁定在 零 偏角附近。

The simulation results show that the locking loop of DTG on moving base can lock DTG nearby the zero deflection angle during the whole course from rest to working and to rest again .

仿真表明：此动基座锁定回路能够较好地将动力调谐陀螺仪在静止→正常工作→静止的整个过程中都能锁定在 零 偏角附近。

After the loading up to the 130 % to 160 % of standard test values the first crack appears in the flexural section . If the loading decreased to zero the crack can be close-up and the deflection spring back .

当荷载达到标准检验荷载的 130%&160%后，截面混凝土出现初始裂缝，卸载后初始裂缝闭合， 变形回复。
