Yuav ua li cas xaiv qhov tsim nyog zipper ntawm niaj hnub science popularization?

Zipper yog ib qho khoom sib txuas hauv peb lub neej niaj hnub, uas ua lub luag haujlwm sib txuas thiab sib khi hauv cov khoom xws li khaub ncaws thiab hnab. Txawm li cas los xij, rau ntau tus neeg, qhov sib txawv ntawm qhov qhib thiab kaw zippers tsis meej heev. Nws yog ib qho tseem ceeb kom nkag siab txog cov qauv thiab kev siv tau ntawm zippers thaum xaiv lawv.

Ua ntej, cia peb muaj kev nkag siab ntxaws txog cov qauv ntawm cov zippers qhib thiab kaw. Tus yam ntxwv ntawm qhov qhib kawg zipper yog tias tsis muaj rov qab code nyob rau hauv qis kawg ntawm cov saw, tab sis ib tug xauv tivthaiv. Thaum lub caij xauv lub xauv, nws yog qhov sib npaug rau lub zipper kaw, thiab los ntawm kev rub lub taub hau tawm tsam cov khoom xauv, cov saw pluaj tuaj yeem sib cais. Lub zipper kaw muaj qhov ruaj khov rov qab thiab tsuas yog rub tau qhib los ntawm qhov loj kawg nkaus. Thaum lub zipper qhib tag nrho, ob txoj hlua hlua txuas ua ke los ntawm tus lej rov qab thiab tsis tuaj yeem sib cais. Cov txheej txheem sib txawv txiav txim siab lawv cov yam ntxwv thiab kev txwv thaum siv.

Qhov thib ob, muaj qhov sib txawv ntawm qhov kev thov ntawm cov zippers qhib thiab kaw zippers. Qhib zippers yog tsim rau cov khoom uas yuav tsum tau qhib thiab kaw, xws li khaub ncaws. Cov zippers kaw zoo dua rau cov khoom uas tsis tas yuav tsum tau qhib, xws li lub hnab tsis tu ncua lossis cov khaub ncaws uas tsis tas yuav tsum tau disassembly. Yog li ntawd, thaum xaiv ib lub zipper, peb yuav tsum tsim nyog xaiv qhov qhib lossis kaw zipper raws li kev xav tau ntawm cov khoom kom ntseeg tau tias nws ua haujlwm tau zoo thiab lub neej ntev.

Hauv kev siv tswv yim, xaiv cov zipper tsim nyog yog qhov tseem ceeb rau cov khoom zoo thiab cov neeg siv kev paub. Yog tias xaiv tsis raug, nws yuav ua rau lub zipper puas, kev siv tsis yooj yim, thiab txawm tias muaj kev nyab xeeb. Yog li ntawd, thaum yuav khoom, cov neeg siv khoom yuav tsum tau xyuam xim rau hom zipper siv thiab xaiv raws li qhov xav tau tiag tiag.

Hauv cov ntsiab lus, kev nkag siab txog cov yam ntxwv ntawm cov qauv thiab kev siv tau ntawm cov zippers qhib thiab kaw yog qhov tseem ceeb rau peb xaiv txoj cai zipper. Tsuas yog los ntawm kev nkag siab tag nrho cov yam ntxwv thiab kev siv cov kev cai ntawm zippers tuaj yeem xaiv cov zipper uas tsim nyog tshaj plaws los xyuas kom meej cov khoom zoo thiab ua haujlwm tau zoo. Kuv vam tias dhau los ntawm kev tshawb fawb niaj hnub no, txhua tus neeg muaj kev nkag siab tob txog cov zippers, thiab tuaj yeem xaiv thiab siv cov khoom zipper kom tsim nyog hauv lub neej txhua hnub.

Tsis tas li ntawd, thaum cov niam txiv yuav cov menyuam cov khaub ncaws rau lawv cov menyuam, lawv yuav tsum tsis tsuas yog xav txog cov tsos thiab tus nqi xwb, tab sis kuj yuav tsum tau them nyiaj ntau dua rau kev txheeb xyuas daim ntawv cim npe thiab qeb ntawm kev txheeb xyuas cov menyuam cov khaub ncaws (raws li lub tebchaws tshiab, cov khaub ncaws menyuam yaus. yuav tsum tau sau nrog cov lus xws li "cov khoom me nyuam mos" lossis "Class A"; Class B yog cov khoom uas tuaj yeem cuam tshuam rau ntawm daim tawv nqaij Class C yog cov khoom uas tsis tuaj yeem cuam tshuam ncaj qha rau ntawm daim tawv nqaij),

Thaum muas khaub ncaws rau cov menyuam yaus hnub nyoog qis dua 7 xyoo lossis cov menyuam mos thiab cov menyuam yaus, nws yog ib qho tseem ceeb tsis txhob xaiv cov khaub ncaws nrog cov hlua ntawm lub taub hau thiab caj dab, vim tias cov hlua khi ntawm lub taub hau thiab caj dab ntawm cov menyuam yaus cov khaub ncaws yuav ua rau raug mob thaum menyuam yaus txav mus los. , los yog ua tsis taus pa thaum cov hlua khi yuam kev rau ntawm caj dab. Thov tiv thaiv menyuam txoj kev nyab xeeb.
