Tus txheej txheem hluav taws xob ua li cas npaj?
Muaj ntau yam kev hloov kho ntawm cov khoom ua si. Txawm li cas los, lawv cov qauv tsim muaj feem ntau zoo sib xws. Xav txog cov cuab yeej thiab txoj cai ntawm kev lag luam uas siv cov piv txwv ntawm cov me nyuam tus tsim hluav taws xob "Znatok".
Qhov khoom ua si no yog ib txheej ntawm cov nplaum uas tso cai rau koj ua hluav taws xob tsis muaj hluav taws xob tsis muaj dabtsi. Yog li, txuas lawv ua ke, koj tuaj yeem tsim kom muaj hluav taws xob ntev ncaj hluav taws xob.
Cov txheej txheem ntawm tus qauv tsim hluav taws xob muaj xws li ntau daim npav uas muaj peev xwm yuav nruab nrog phau ntawv, sib nqus, lub teeb, dej, suab thiab hluav taws xob, thiab kev sib tiv tauj kuj.
Dab tsi yog muaj nyob hauv cov khoom siv hluav taws xob?
Cov txheej no suav nrog ntau yam hauv cov cheebtsam, nrog rau cov sib txuas uas muaj ntau qhov ntev. Txhua tus ntawm lawv muaj ib tug xov tooj uas muaj nyob rau hauv ib kab lus, thiab kuj muaj cov phiaj xwm xim thiab xim.
Cov khoom siv kuj muaj xws li ntau tus qauv piav qhia uas tseem to taub. Nrog lawv cov kev pab koj tuaj yeem ua kom txog li 1000 txoj kev sib txuas ntau. Daim npav daim ntawv muaj cov ncauj lus tsis hais txog cov khoom siv hluav taws xob xwb, tab sis kuj muaj kev ua haujlwm ntawm lub cev, thiab muaj cov lus qhia. Tag nrho cov no yuav cia tus me nyuam sim ua thiab xyaum nws txoj kev xav, ua ib yam tshiab.
Ntau ntau cov ntsiab lus thiab cov qauv tsim tawm yuav tsis tso tseg txhua tus menyuam tsis tuaj yeem. Ntawm no yog ib daim ntawv teev me me ntawm cov khoom uas tuaj yeem cuam tshuam thiab ua rau cov menyuam nyiam:
- kev teeb pom kev zoo;
- ib lub teeb, nrog rau ib qho npuaj teg los yog ib lub dav hlau cua;
- suab paj nruas kiv cua;
- hluav taws xob hluav taws xob;
- kev ruaj ntseg;
- xov tooj cua chaw;
- txoj kev tshawb no ntawm Morse code;
- lub tshuab hluav taws xob;
- suab paj nruag nyob rau hauv xov tooj cua, ua ke ntawm qhov pib ntawm qhov tsaus ntuj;
- ob lub teeb txawb, ci ntsa iab nrog ib koog ntawm cua;
- suab paj nruas qhov rooj kaw;
- megaphone;
- lie detector, etc.
Vim li cas thiaj yog ib qho hluav taws xob tsim tau?
Hom kev tsim hluav taws xob no yuav siv tsis tau rau qhov kev ua si xwb, tab sis kuj yog rau kev qhia. Hauv nws cov teeb muaj xws li txog 20 yam kev kawm, uas yuav siv tau zoo hauv lub tsev kawm ntawv ntawm kev kawm, piv txwv li, hauv cov tshooj physics. Yog li, tus tsim qauv yuav pab tau cov xib fwb thaum kawm txog cov ncauj lus xws li "Suab", "Mechanical oscillations and waves", "Electrical phenomena". Qhov zoo ntawm cov zaj lus qhia nrog kev siv lub tshuab hluav taws xob yog qhov tseeb tias cov me nyuam muaj peev xwm xyaum tau qhov kev paub lawv tau txais. Ntxiv mus, muaj ntau tus menyuam muaj kev nco zoo nkauj. Yog li no, kev siv lub tshuab hluav taws xob yuav tsuas pab txhawb rau txoj kev kawm.
Rau cov hnub nyoog twg yog qhov hluav taws xob designer npaj?
Txawm tias muaj tseeb tias thaum xub thawj siab tias tus qauv tsim hluav taws xob zoo li tsis yooj yim to taub, nws kuj siv tau los ua si nrog cov menyuam kawm ntawv preschool. Li ntawd, nws muaj peev xwm ua tau zoo siv thaum kawm paj nrog me nyuam 3-4 xyoo. Tsis tas li ntawd xwb, thaum pom tus me nyuam ob peb zaug ib qho yooj yim, nws yuav sim rov qab nws tus kheej. Cov kev kawm no yuav ua rau kev loj hlob ntawm kev xav, kev nco qab, kev xav thiab kev loj hlob, uas yog qhov tseem ceeb rau kev loj hlob ntawm cov menyuam yaus. Tej cov kws tsim hluav taws xob muaj peev xwm ua rau muaj kev ntxhov siab rau cov tub hluas ntxhais hluas, yog qhov tseem ceeb rau kev kawm ntawm lub cev.
