▍Iyini I-CTIA CERTIFICATION?

I-CTIA, isifinyezo se-Cellular Telecommunications and Internet Association, yinhlangano yomphakathi engenzi nzuzo eyasungulwa ngo-1984 ngenjongo yokuqinisekisa ukuhlomula kwabaqhubi, abakhiqizi nabasebenzisi. I-CTIA iqukethe bonke opharetha base-US nabakhiqizi abavela kumasevisi omsakazo weselula, kanye namasevisi edatha angenantambo nemikhiqizo. Isekelwe yi-FCC (Federal Communications Commission) kanye neCongress, i-CTIA yenza ingxenye enkulu yemisebenzi nemisebenzi eyayisetshenziselwa ukwenziwa uhulumeni. Ngo-1991, i-CTIA yakha uhlelo lokuhlola lomkhiqizo olungachemile, oluzimele nolwendawo eyodwa kanye nesitifiketi somkhakha ongenazintambo. Ngaphansi kwesistimu, yonke imikhiqizo engenantambo esebangeni labathengi izothatha izivivinyo zokuthobela imithetho futhi leyo ethobelana namazinga afanele izovunyelwa ukusebenzisa ukumaka kwe-CTIA nokushayisana kwamashalofu ezitolo emakethe yezokuxhumana yaseNyakatho Melika.

I-CATL (CTIA Authorized Testing Laboratory) imele amalebhu agunyazwe yi-CTIA ukuze ahlolwe futhi abuyekezwe. Imibiko yokuhlola ekhishwe ku-CATL izogunyazwa yonke yi-CTIA. Nakuba eminye imibiko yokuhlola kanye nemiphumela evela ku-non-CATL ngeke ibonwe noma ingakwazi ukufinyelela ku-CTIA. I-CATL egunyazwe yi-CTIA iyahlukahluka ezimbonini nasekutholeni izitifiketi. I-CATL kuphela efanelekela ukuhlolwa nokuhlolwa kokuthobela ibhethri ekwazi ukufinyelela esitifiketini sebhethri ukuze ihambisane ne-IEEE1725.

▍CTIA Amazinga Wokuhlola Ibhethri

a) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobela IEEE1725— Kusebenza Ezinhlelweni Zebhethri ezineseli elilodwa noma amaseli amaningi axhunywe ngokuhambisana;

b) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobelana ne-IEEE1625— Kusebenza Ezinhlelweni Zebhethri ezinamaseli amaningi axhunywe ngokuhambisana noma kokubili okuhambisanayo nochungechunge;

Amathiphu afudumele: Khetha ngenhla kwamazinga wesitifiketi ngokufanelekile kumabhethri asetshenziswa omakhalekhukhwini namakhompyutha. Ungasebenzisi kabi i-IEE1725 kumabhethri kumakhalekhukhwini noma i-IEEE1625 kumabhethri akukhompyutha.

▍Kungani i-MCM?

●Ubuchwepheshe obuqinile:Kusukela ngo-2014, i-MCM ibihambela inkomfa yamaphakethe webhethri ebanjwa yi-CTIA e-US minyaka yonke, futhi iyakwazi ukuthola isibuyekezo sakamuva futhi iqonde amathrendi enqubomgomo emisha mayelana ne-CTIA ngendlela esheshayo, enembayo nesebenzayo.

●Ukufaneleka:I-MCM iyi-CATL egunyazwe yi-CTIA futhi ifaneleka ukwenza zonke izinqubo ezihlobene nesitifiketi okuhlanganisa ukuhlola, ukuhlola kwasefekthri nokulayisha umbiko.

Ukusatshalaliswa okushisayo kwemojuli kuba nezigaba ezilandelayo: Ukunqwabelana kokushisa ngemva kokuhlukunyezwa kokushisa kweseli, ukubaleka kokushisa kweseli kanye nokubaleka kwemojuli yokushisa. Ukubaleka okushisayo kungqamuzana elilodwa akunamandla; kodwa-ke, lapho ukushisa kusakazeka kwamanye amaseli, ukusabalalisa kuzodala umphumela we-domino, okuholela ekubalekeni okushisayo kwe-module yonke, ukukhulula amandla amakhulu. Umfanekiso 1 ubonisa umphumela wokuhlolwa kokubaleka okushisayo. Imojula ivutha ngenxa yokusabalalisa okungenakuvinjelwa.I-conductivity yokushisa ngaphakathi kweseli izohluka ngokuya ngezinkomba ezahlukene. I-coefficient of heat conductivity izoba phezulu esiqondisweni esihambisana ne-roll core yeseli; kuyilapho isiqondiso esime mpo ku-roll core sinokusebenza okuphansi. Ngakho-ke ukusabalala okushisayo kusuka ohlangothini kuya kolunye phakathi kwamaseli kuyashesha kunalokho okwenzeka ngamathebhu kuya kumaseli. Ngakho-ke ukusakazeka kungabonakala njengokusakazeka kohlangothi olulodwa. Njengoba amamojula ebhethri edizayinelwe ukuminyana kwamandla aphezulu, isikhala phakathi kwamaseli siya siba sincane, okuzokwenza kube kubi ukusakazeka kokushisa. Ngakho-ke, ukucindezela noma ukuvimbela ukusabalala kokushisa kumojula kuzobhekwa njengendlela ephumelelayo yokunciphisa izingozi.
Singakwazi ukunqanda ukuphuma okushisayo ngokuqhubekayo noma ngokungenzi lutho.Ukucindezela okusebenzayo kokusakazwa okushisayo kusekelwe kakhulu ohlelweni lokulawula okushisayo, njengokuthi:1)Setha amapayipi okupholisa phansi noma izinhlangothi zangaphakathi zemojuli, bese ugcwalisa ngoketshezi olupholile. Ukugeleza koketshezi olupholisayo kunganciphisa ngempumelelo ukusakazeka.2)Misa amapayipi okuqothula umlilo phezu kwemojuli. Uma kubaleka okushisayo, igesi lokushisa eliphezulu elikhishwe ebhethrini lizokwenza amapayipi afafaze isicisha-mlilo ukuze acindezele ukusakazeka.Nokho, ukuphatha okushisayo kudinga izingxenye ezengeziwe, okuholela ezindleko eziphakeme kanye nokuncishiswa kwamandla aphansi. Kukhona futhi ukuthi kungenzeka ukuthi uhlelo lokuphatha lungasebenzi.
