根据液晶的连续体理论及微扰原理得出HAN -FFS简化模型的上升时间常数和下降时间常数。

By using liquid crystal continuum theory and perturbation principle, we obtain the expression of switching-on time constant and switching-off time constant for simplified HAN-FFS mode.

为使误差降低到1%，必须等待大约两倍的上升时间。而为了使误差降低到0.1%，则必须等待大约三倍的上升时间(或者接近7倍时间常数的时间)。

To reduce the error to 1%, about two rise times must be allowed, while reducing the error to 0.1% would require roughly three rise times (or nearly seven time constants).
