1. Lub luag haujlwm ntawm lub zog nruab nrab ntawm ib puag ncig, suav nrog lub luag haujlwm ntawm cov neeg ua haujlwm, kho thiab ib puag ncig.
2. Cov yam ntxwv sab hauv uas muaj feem xyuam rau kev ua haujlwm ntawm lub tshuab raj kauv thiab kev ua haujlwm ntawm txhua lub tshuab, xws li kev thauj khoom, kev vibration, kub, thiab lwm yam.
3. Lub zog latent tau sau nyob rau hauv qhov chaw ntawm lub tshuab spiral duct thaum tsim khoom thiab sib dhos. Cov zog no feem ntau muaj nyob rau hauv daim ntawv ntawm txhua yam zog, thermal zog, thiab chemical zog. Thaum lub zog nce mus txog ib qho nqi, cov khoom yuav raug puas tsuaj ua ntej. Nws yog manifested raws li abrasion, deformation, tawg, qaug zog, corrosion, thiab lwm yam. Qhov tshwm sim ntawm kev puas tsuaj kuj yuav hloov cov yam ntxwv ntawm cov kauv duct tshuab qhov chaw.
