During that period, I was like a spinning top, spinning from house to workplace, and from workplace to hospital. After my Prince was out of the hospital, he insisted on going back to work right away even though he had to be in a wheelchair for a month. So taking him to work was my job. Twice a day I had to lift the heavy wheelchair into the trunk and then lift it out of the trunk.

那段期间，我就像一个陀螺，每天从家里转到办公室，再从办公室转到医院，在我的王子出院后，他坚持立刻回去上班，尽管他仍需坐在轮椅上一个月，所以带他去上班变成了我的工作，每天两次，我必须把笨重的轮椅搬进车厢，再把它搬出车厢。

The disturbing torque caused by carrier perturbation in the control system of seeker stabilized platform and the swing caused by sight angular angle were analyzed, the influence o f selection of different output dot of sight angular speed on sight angle and decoupling and the requirement for cont rol system transfer function were analyzed.
