1. Flow kev ua tau zoo: Cov hniav ntev yuav tsum muaj kev ua tau zoo txaus kom txo qis kev sib txhuam thiab kev quab yuam centrifugal tau ntsib los ntawm cov kua dej dhau los.
2. Cov khoom siv kho tshuab: Cov hniav ntev yuav tsum muaj lub zog siab thiab hnav tsis kam tiv taus siab thiab kev sib txhuam ntawm qhov kub thiab txias.
3. Thermodynamic zog: Cov hniav ntev yuav tsum muaj cov thermal conductivity zoo kom tso cai rau cov cua sov sai sai hauv qhov kub ntawm - qhov kub thiab txias, tiv thaiv deformation thiab melting.
4. Cov txheej txheem tsim khoom: Cov txheej txheem tsim khoom rau cov hniav ntev yuav tsum tau ua kom zoo tshaj plaws kom paub meej cov hniav thiab qhov zoo.
