Yuav ua li cas xaiv lub teeb taub hau zoo

Yog tias koj nyiam kev nce roob lossis mus ua teb, lub teeb taub hau yog cov khoom siv sab nraum zoov tseem ceeb heev! Txawm tias nws yog kev taug kev thaum hmo ntuj lub caij ntuj sov, kev taug kev hauv roob, lossis kev mus pw hav zoov hauv hav zoov, lub teeb taub hau yuav ua rau koj txoj kev txav mus los yooj yim dua thiab muaj kev nyab xeeb dua.

2. Hom teeb pom kev zoo

Yog tias lub teeb taub hau sib txawv los ntawm hom, muaj ob hom kev tsom xam thiab astigmatism (lub teeb dej nyab), astigmatism yog qhov tsim nyog rau kev siv thaum ua tej yam nyob ze lossis taug kev nrog pab pawg, thiab qhov qaug zog ntawm lub qhov muag yuav raug txo qis piv rau hom kev tsom xam, thiab hom kev tsom xam yog qhov tsim nyog rau kev irradiation thaum nrhiav txoj hauv kev deb. Qee lub teeb taub hau yog ob hom kev hloov pauv, koj tuaj yeem them sai dua thaum yuav khoom.

Qee lub teeb taub hau siab heev kuj tseem yuav muaj "hom teeb ci ntsa iab", "hom teeb liab" thiab lwm yam. "Hom teeb ci ntsa iab" tuaj yeem muab faib ua ntau yam, xws li "hom teeb ci ntsa iab", "hom teeb liab", feem ntau siv rau kev siv teeb liab thaum muaj xwm txheej ceev, thiab "hom teeb liab" yog qhov tsim nyog rau kev pom kev hmo ntuj, thiab lub teeb liab yuav tsis cuam tshuam rau lwm tus, thaum hmo ntuj hauv tsev pheeb suab lossis tsev roob rau lub sijhawm pw tsaug zog tuaj yeem txiav mus rau lub teeb liab, chav dej lossis cov khoom siv tiav yuav tsis cuam tshuam rau lwm tus pw tsaug zog.

3. Qib dej tsis nkag yog dab tsi?

Nws raug pom zoo kom IPX4 siab dua qib tiv thaiv dej, tab sis qhov tseeb, nws tseem nyob ntawm lub hom, qib tiv thaiv dej tsuas yog rau kev siv xwb, yog tias cov qauv tsim khoom lag luam tsis nruj heev, nws tseem yuav ua rau lub teeb taub hau puas tsuaj los ntawm dej! # Kev pabcuam tom qab muag khoom kuj tseem ceeb heev

Kev ntsuas dej tsis nkag

IPX0: Tsis muaj kev tiv thaiv tshwj xeeb.

IPX1: tiv thaiv cov dej ntws tsis pub nkag mus.

IPX2: Lub qaij ntawm lub cuab yeej yog nyob rau hauv 15 degrees kom tsis txhob muaj cov dej ntws nkag mus.

IPX3: tiv thaiv dej kom tsis txhob nkag mus.

IPX4: Tiv thaiv dej kom tsis txhob nkag mus.

IPX5: Muaj peev xwm tiv taus cov dej ntawm rab phom tsuag qis tsawg kawg 3 feeb.

IPX6: Muaj peev xwm tiv taus cov dej ntawm rab phom txau siab rau tsawg kawg 3 feeb.

IPX7: Tiv taus kev tsau hauv dej tob txog li 1 meter rau 30 feeb.

IPX8: Tiv taus kev sib txuas lus hauv dej tob tshaj 1 meter.

4. Txog cov roj teeb

Muaj ob txoj hauv kev los khaws lub zog rau lub teeb taub hau:

[Roj teeb pov tseg]: Muaj teeb meem nrog cov roj teeb pov tseg, uas yog, koj yuav tsis paub tias muaj zog npaum li cas tom qab siv, thiab seb koj puas yuav yuav ib qho tshiab thaum koj nce roob tom ntej, thiab nws tsis zoo rau ib puag ncig dua li cov roj teeb uas rov them tau.

[Lub roj teeb rov qab tau]: Cov roj teeb rov qab tau feem ntau yog "roj teeb nickel-hlau hydride" thiab "roj teeb lithium", qhov zoo yog tias nws muaj peev xwm tuav lub zog ntau dua, thiab zoo dua rau ib puag ncig, thiab muaj lwm yam ntxwv, uas yog, piv nrog cov roj teeb pov tseg, yuav tsis muaj roj teeb xau.
