2. Slump: Ntau dhau sagging los yog zawv zawg ntawm cov vuas vim qhov tsis zoo ntawm cov nplaum nplaum los yog cov txheej txheem thov, ua rau cov pobzeb tsis sib xws lossis qhov sib txawv ntawm cov vuas.
3. Pobzeb Slippage: Cov pobzeb hloov lossis zawv zawg tawm ntawm txoj haujlwm thaum lub sijhawm teeb tsa lossis kho, feem ntau tshwm sim los ntawm kev tiv thaiv tsis txaus lossis kev sib dhos ntawm cov pobzeb tsis raug.
4. Kev ziab ntxov ntxov: Kev ziab sai sai ntawm cov nplaum ua ntej kev teeb tsa cov pobzeb tiav, ua rau cov adhesion tsis zoo, nyuaj rau kev hloov kho, lossis kho tsis txaus.
5. Bubbling lossis Hollow Sounds: Cov hnab ntim huab cua lossis cov voids dai hauv qab cov vuas, ua rau lub suab nrov lossis "drummy" thaj chaw thaum tapping, qhia tias tsis muaj cov nplaum nplaum lossis kev npaj tsis raug.
