Qhov zoo ntawm cov kua qab zib ntsuas thiab ntsuas qhov ntom ntom
1. Txhua qhov kev daws teeb meem tuaj yeem ntsuas tau sai yam tsis muaj kev txwv
2. Kev nyeem ncaj qha ntawm qhov ntom ntom, cov ntsiab lus qab zib, Baume degree
3. Kev ntsuas qhov tseeb, kev ua haujlwm yooj yim, ruaj khov thiab ruaj khov
4. Nws yog qhov ntsuas dynamic. Thaum lub sij hawm ntsuas, cov mis ntawm cov kua yog hloov txhua lub sij hawm, thiab tus nqi ceev kuj hloov thiab hloov kho tam sim ntawd.
5. Nrog rau qhov ntsuas kub ntawm cov dej kub, qhov cua buoyancy density them nyiaj teeb tsa
6. Nrog buzzer tswb thiab overload tswb muaj nuj nqi
