Cov chav huv yog tam sim no dav siv hauv cov khoom siv hluav taws xob siab xws li cov khoom siv hluav taws xob, kev lag luam lag luam, khoom noj khoom haus, kev tshawb fawb tsheb, thiab lwm yam.
Cov lus qhia kev ua haujlwm ntawm chav huv xws li huab cua huv si, microbial concentration, huab cua, cua tshuab sib txawv, suab sib txawv, thiab lub teeb taws.
Tshwj xeeb tsis muaj qhov hluav taws xob tshwj xeeb yog kev co, hluav taws xob zoo li, kev puas tsuaj roj confration, radiation siv zog.
Txawm li cas los xij, txhua qhov kev lag luam tsom rau cov kev sib txawv. Piv txwv li, cov microelectronics zoo huv chav muaj cov kev ntsuas pa ntawm cov pa pa, thiab cov khoom siv huv si muaj cov phiaj xwm huab cua kom muaj qhov kub thiab txias.
