The new compensation scheme used loading motor output shaft angle displacement for the surplus torque feed-forward compensator,which can reduce the system order while effectively eliminated surplus torque.

提出了将加载马达输出轴角位移作为输入信号的多余力矩前馈补偿方案，在有效抑制多余力矩的同时降低了系统阶次。

Patients must always be informed regarding the potential for development of a PDPH because ambulatory patients usually expect to resume their normal activities shortly after surgery. Additional recommendations to reduce the incidence of headache include keeping the bevel edge of the conventional needle parallel to the longitudinal axis of the body and the dural fibers and avoiding multiple attempts at subarachnoid needle placement.

病人术前必须被告知有发生PDPH的可能，因为门诊手术病人通常希望术后短期恢复他们的正常活动，另外为减少PDPH推荐穿刺时保持针斜面平行身体长轴和硬膜外纤维走形，避免多次尝试穿入蛛网膜下腔。
