However, the chattering with high frequency in sliding mode control systems is barrier for the application to the practice engineering problems.
然而滑模变结构控制带来的高频抖振是其应用到实际系统中的障碍。

The extent is generally related to their potency, frequency of application, the patient's body surface area, and the skin's ability to act as a barrier.
抑制程度基本取决于他们的浓度，给药频率，患者的体表面积和皮肤的屏障能力。
