Cov khoom ntiv tes uas niaj hnub siv los siv hauv cov tshuab hluav taws xob thiab cov khoom siv hluav taws xob
Tus ntiv tes los tiv thaiv zoo li qub yog ua los ntawm cov kua nplaum thiab cov yas lo. Nws tsis muaj cov roj salicone lossis amide, uas tuaj yeem tiv thaiv tau hluav taws xob.
Cov kev kho tshwj xeeb tshwj xeeb yog txo cov theem ntawm ions, seem, plua plav thiab lwm yam kab mob.
Kev tswj kev tiv thaiv ntawm kev tsim hluav taws xob zoo li qub, tsim kev tuav cov khoom qub, kev kho plua plav uas tsis tshua muaj, tsim nyog rau chav tu.
Tivthaiv: 10 rau lub hwj chim ntawm 8 - 10 rau lub zog 10; xim: dub, daj, liab (beige ntau dua) thiab pob tshab;
Lub tes tsho zoo li qub thaiv tau ib hom kab xev, ib hom tsis yog hom, ib yam dab tsi, ib hom duab matte, thiab cov zoo li.
Cov cwj pwm uas niaj hnub siv tau thaiv tawm ntawm tawv nqaij, tiv thaiv tawm hws sting los ntawm cov fingertips los ntawm cov khoom paug, ultra-thin fingertips rau cov ntiv tes yawm suab, kom sab hauv kom tsis txhob ntiv tes, thiab pheej yig.
Cov khoom siv ntiv tes uas niaj hnub siv tau tsim nyog siv rau hauv kev lag luam hluav taws xob, hluav taws xob, optoelectronics, tshuaj, tshuaj lom neeg kev lag luam, chaw kuaj tshuaj thiab lwm cov hauj lwm.
