In the vertical direction, follow-up water diverted from the high-permeability layer to the low-permeability layer to enhance the verticalsweep efficiency.
在纵向上，后续水从高渗层转向低渗透层，提高纵向波及系数。

Verification works on vertical deflection sensitivity and horizontal sweep speed of digital oscilloscope are summarized.
总结了数字示波器垂直偏转灵敏度和水平扫描速度的检定工作。
