    Qhov Zoo ntawm Khoom

    1. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov yeeb nkab sib txuas yog nws lub zog zoo heev. Cov txheej txheem vuam sib txuas ua rau kev vuam txuas ntxiv mus, yog li ua kom cov qauv ntawm cov yeeb nkab zoo dua. Qhov no ua rau lawv zoo tagnrho rau kev thauj cov kua thiab cov pa roj hauv qab qhov siab.

    2. Cov txheej txheem tsim khoom zoo, ua rau cov kav dej ntev dua yam tsis tas yuav muaj cov pob qij txha, uas tuaj yeem ua rau muaj qhov tsis muaj zog.

    3. Lwm qhov zoo dua ntawmhelical seam yeeb nkabyog nws qhov ua tau ntau yam. Lawv tuaj yeem tsim tau ntau yam txoj kab uas hla thiab phab ntsa tuab rau ntau yam kev siv los ntawm kev thauj roj thiab roj mus rau cov kab ke dej.

    4. Cov tuam txhab uas tsim cov kav dej no muab qhov tseem ceeb rau kev txaus siab ntawm cov neeg siv khoom thiab muab kev pabcuam ua ntej muag, thaum muag, thiab tom qab muag. Qhov kev cog lus no ua kom cov neeg siv khoom tau txais cov khoom tsim rau lawv cov kev xav tau tshwj xeeb, txhim kho kev paub tag nrho.

    Qhov tsis zoo ntawm cov khoom

    1. Cov txheej txheem vuam kauv tuaj yeem nyuaj dua li cov txheej txheem vuam ib txwm muaj, uas tuaj yeem ua rau cov nqi tsim khoom ntau dua.

    2. Txawm hais tias cov kav dej sib txuas ua ke muaj zog, lawv yuav tsis tshua tiv taus qee yam xeb dua li lwm cov khoom siv yeeb nkab thiab xav tau cov txheej tiv thaiv lossis kev kho mob.

    Cov Lus Nug Feem Ntau

    Q1: Cov yeeb nkab sib txuas yog dab tsi?

    Cov yeeb nkab sib txuas ua ke yog tsim los ntawm kev siv txoj kev tshwj xeeb hu ua cov txheej txheem vuam sib txuas. Cov thev naus laus zis tshiab no suav nrog cov hlau kub dov uas raug tsim ua lub cylindrical thiab vuam raws li cov yeeb nkab sib txuas. Cov yeeb nkab tsis yog tsuas yog muaj lub zog siab xwb tab sis kuj ruaj khov zoo heev, ua rau nws zoo tagnrho rau ntau yam kev siv, suav nrog kev thauj mus los roj thiab roj av, kev muab dej thiab kev txhawb nqa cov qauv.

    Q2: Vim li cas ho xaiv cov yeeb nkab zoo?

    Qhov zoo tshaj plaws ntawm cov kav dej sib txuas zoo yog lawv txoj kev tsim kho kom ruaj khov. Cov txheej txheem vuam sib txuas ua rau muaj kev vuam tas mus li, uas ua rau cov yeeb nkab ruaj khov thiab tiv taus siab. Tsis tas li ntawd, cov yeeb nkab no tuaj yeem tsim ntau qhov ntau thiab tsawg thiab tuab kom tau raws li qhov xav tau tshwj xeeb ntawm ntau yam haujlwm sib txawv.

    Q3: Kuv yuav tsum nrhiav dab tsi ntawm tus neeg muag khoom?

    Thaum xaiv ib lub tuam txhab muab cov yeeb nkab uas muaj cov kauv sib txuas, nws yog ib qho tseem ceeb uas yuav tsum xaiv ib lub tuam txhab uas muab kev txaus siab rau cov neeg siv khoom tso ua ntej. Nrhiav ib lub tuam txhab uas muab kev pabcuam ua ntej muag, kev muag khoom, thiab kev pabcuam tom qab muag. Ib lub tuam txhab uas muaj npe nrov yuav xyuas kom meej tias nws cov khoom ua tau raws li cov lus qhia tshwj xeeb thiab tuaj yeem ua raws li koj cov kev xav tau tshwj xeeb, xyuas kom meej tias koj tau txais cov khoom zoo thiab cov kev pabcuam uas koj cov neeg siv khoom yuav txaus siab.
