Cov ntawv txias-dov yog tsim los ntawm cov ntawv txias-kuav los tiag, ua los ntawm kev txo cov khoom tuab ntawm cov kub dov coils. Lawv yog qhov zoo tshaj plaws rau cov xwm txheej uas cov khoom yuav raug nthuav tawm thiab yuav tsum tau ua kom tiav qhov sib txawv. Muab nws cov yam ntxwv xws li kev tiv thaiv thiab tuav, tsuas yog siv nyob rau hauv ntu:
Tsheb;
Cov khoom siv (kab dawb);
Kev tsim kho pej xeem (ferragens thiab pab pawg).
Cov ntawv txias-dov yog siv dav hauv cov chaw lag luam uas xav tau cov khoom siv hlau nrog cov khoom zoo, uas yog vim li cas lawv muaj kev ua tiav ntau dua, raws li tshwm sim hauv kev tsim cov geladeiras thiab hluav taws kub.
