▍Kodi ANATEL Homologation ndi chiyani?

ANATEL ndichidule cha Agencia Nacional de Telecomunicacoes chomwe ndi boma la Brazil kuti lizipereka ziphaso zovomerezeka komanso zodzifunira. Kuvomereza ndi kutsata njira zake ndizofanana pazogulitsa zapakhomo ndi zakunja ku Brazil. Ngati zogulitsa zikugwira ntchito ku chiphaso chokakamiza, zotsatira zoyesa ndi lipoti ziyenera kugwirizana ndi malamulo ndi malamulo omwe ANATEL adafunsa. Satifiketi yogulitsa iyenera kuperekedwa ndi ANATEL poyamba zinthu zisanagawidwe pakutsatsa ndikuyikidwa kuti zigwiritsidwe ntchito.

▍Ndani ali ndi udindo pa ANATEL Homologation?

Mabungwe ovomerezeka aboma la Brazil, mabungwe ena ovomerezeka ndi ma lab oyesa ndi ANATEL certification Authority pakuwunika njira yopangira zinthu, monga njira yopangira zinthu, kugula, kupanga, pambuyo pa ntchito ndi zina zotero kuti zitsimikizire kuti chinthucho chikuyenera kutsatiridwa. ndi Brazil standard. Wopanga adzapereka zikalata ndi zitsanzo zoyesa ndikuwunika.

▍Chifukwa chiyani MCM?

● MCM ili ndi zaka 10 zokumana nazo zambiri komanso zothandizira pakuyesa ndi certification: machitidwe apamwamba kwambiri, gulu laukadaulo lodziwa bwino kwambiri, ziphaso zachangu komanso zosavuta komanso zothetsera zoyezetsa.

● MCM imagwira ntchito ndi mabungwe angapo odziwika bwino mdera lanu omwe amapereka mayankho osiyanasiyana, olondola komanso osavuta kwa makasitomala.

Crush ndi mayeso odziwika bwino kuti atsimikizire chitetezo cha ma cell, kuyerekezera kugundana kwa ma cell kapena zinthu zomwe zimagwiritsidwa ntchito tsiku ndi tsiku. Nthawi zambiri pali mitundu iwiri ya mayeso ophwanya: kuphwanya pang'ono ndi kuphwanya pang'ono. Poyerekeza ndi kuphwanya kwaphwando, kulowera pang'ono komwe kumachitika chifukwa chozungulira kapena cylindrical indenter kumapangitsa kuti selo lisagwire ntchito. Kukuthwa kwa inndenter, kupsinjika kwambiri pakatikati pa batire ya lithiamu, kumapangitsa kuti pakatikati pakatikati pakhale kuphulika kwapakati, komwe kumayambitsa kupindika komanso kusamuka kwa pachimake, komanso kumabweretsa zovuta zazikulu monga kutayikira kwa electrolyte kapena ngakhale moto. Ndiye kuphwanya kumapangitsa bwanji kuti cell isagwire ntchito? Apa ndikudziwitseni za kusinthika kwa mkati kwa pachimake pamayeso am'deralo. Mphamvuyo imasamutsidwa mkati mwa batire, ndipo gulu la cell limayambanso kupunduka.
 Ndi kukanikizidwa kwina kwa mutu wophwanyidwa, mapindikidwewo akukulirakulira ndipo kukhazikika kumapangidwa. Pa nthawi yomweyo, kusanjikiza katayanitsidwe pakati pa ma elekitirodi aliyense wosanjikiza pang'onopang'ono adzafupikitsidwa. Pansi pa kupanikizana kosalekeza, wosonkhanitsa wamakono amapindika ndi kupunduka, ndipo magulu ometa ubweya amapangidwa. Pamene mapindikidwe a elekitirodi chuma kufika malire, elekitirodi zakuthupi adzabala ming'alu.
 Ndi kuchuluka kwa mapindikidwe, ming'aluyo imafikira pang'onopang'ono mpaka kwa wosonkhanitsa wapano, yemwe amang'ambika ndikutulutsa ductile fracture. Kuphatikiza apo, kuwonongeka kwa ma radial kumakulitsidwa chifukwa cha kuchuluka kwa kupsinjika komanso kusuntha kwa ma radial.
