Ungayikhetha njani i-zipper efanelekileyo yokusasazwa kwesayensi yemihla ngemihla?

I-Zipper isinxibelelanisi esiqhelekileyo kubomi bethu bemihla ngemihla, edlala indima yokudibanisa kunye nokutywinwa kwizinto ezifana nempahla kunye neengxowa.Nangona kunjalo, kubantu abaninzi, umahluko phakathi kweeziphu ezivulekileyo nezivaliweyo azicaci kakuhle.Kubalulekile ukuqonda isakhiwo kunye nokusebenza kweeziphu xa ukhetha.

Okokuqala, masibe nokuqonda okucacileyo kwezakhiwo zeeziphu ezivulekileyo nezivaliweyo.Uphawu lwe-zipper yokuphela evulekileyo kukuba akukho khowudi yangasemva ekupheleni kwekhonkco, kodwa icandelo lokuvala.Xa into yokukhiya ivaliwe, ilingana ne-zipper evaliweyo, kwaye ngokutsala intloko yokutsala ngokubhekiselele kwinto yokutshixa, umtya wekhonkco unokwahlulwa.I-zipper evaliweyo inobungakanani obungaguqukiyo obungasemva kwaye inokutsalwa ivuliwe kuphela ukusuka kwisiphelo sobungakanani bangaphambili.Xa i-zipper ivulekile ngokupheleleyo, iintambo ezimbini zekhonkco zixhunyiwe kunye nekhowudi yangasemva kwaye ayikwazi ukuhlukana.Umahluko wesakhiwo umisela iimpawu kunye nezithintelo xa zisetyenziswa.

Okwesibini, kukho iyantlukwano kububanzi besicelo phakathi kweeziphu ezivulekileyo kunye neeziphu ezivaliweyo.Iiziphu ezivulekileyo zifanelekile kwizinto ezifuna ukuvulwa nokuvala rhoqo, njengempahla.Iiziphu ezivaliweyo zifanelekile ngakumbi kwizinto ezingadingi ukuvulwa rhoqo, njengeengxowa eziqhelekileyo okanye iimpahla ezingadingi ukuchithwa rhoqo.Ngoko ke, xa sikhetha i-zipper, kufuneka sikhethe ngokufanelekileyo i-zipper evulekileyo okanye evaliweyo ngokusekelwe kwiimfuno zokusetyenziswa kwento ukuqinisekisa ukusebenza kwayo kunye nobomi.

Kwizicelo ezisebenzayo, ukukhetha i-zipper efanelekileyo kubalulekile kumgangatho wemveliso kunye namava omsebenzisi.Ukuba ikhethwe ngokungafanelekanga, kunokukhokelela kumonakalo we-zipper, ukuphazamiseka ekusebenziseni, kunye neengozi zokhuseleko.Ngoko ke, xa kuthengwa iimveliso, abathengi kufuneka banikele ingqalelo kuhlobo lweziphu ezisetyenzisiweyo kwaye bakhethe ngokweemfuno zangempela.

Isishwankathelo, ukuqonda iimpawu zesakhiwo kunye nokusebenza kweeziphu ezivulekileyo nezivaliweyo kubalulekile ukuba sikhethe i-zipper efanelekileyo.Kuphela ngokuqonda ngokupheleleyo iimpawu kunye neemfuno zokusetyenziswa kweeziphu sinokukhetha eyona ziphu ifanelekileyo ukuqinisekisa umgangatho wemveliso kunye nokusebenza kakuhle.Ndiyathemba ukuba ngokuthandwa kwenzululwazi yanamhlanje, wonke umntu unokuqonda okunzulu kweeziphu, kwaye unokukhetha kwaye asebenzise iimveliso zeziphu ngokunengqiqo ngakumbi kubomi bemihla ngemihla.

Ukongeza, Xa abazali bethengela abantwana babo iimpahla zempahla, akufanele bacinge kuphela ngenkangeleko kunye neemeko zexabiso, kodwa kwakhona bahlawule ingqalelo ngakumbi kwi-hang tag yokuchongwa kunye nodidi lokuchongwa kwempahla yabantwana (ngokomgangatho omtsha wesizwe, iimpahla zomntwana. kufuneka ibhalwe ngamagama anjengelithi “imveliso yeentsana” okanye “Udidi A” ziimveliso ezinokudibana nolusu udidi C ziimveliso ezingenako ukudibana ngqo nolusu);

Xa uthengela iimpahla zabantwana abangaphantsi kweminyaka eyi-7 okanye iintsana kunye nabantwana abancinci, kubalulekile ukuba ungakhethi iimpahla ezineentambo entloko nasentanyeni, njengoko iintambo ezisentloko nasemqaleni weempahla zabantwana zingabangela ukulimala ngengozi xa abantwana behambahamba. , okanye ukufuthaniselwa xa iintambo zibekwe ngempazamo entanyeni.Nceda ukhusele ukhuseleko lwabantwana.
