▍ Chii chinonzi ANATEL Homologation?
ANATEL ipfupi yeAgencia Nacional de Telecomunicacoes inova chiremera chehurumende yeBrazil kune zvigadzirwa zvekutaurirana zvakasimbiswa zvezvitupa zvekumanikidzira uye zvekuzvidira. Kubvumidza kwayo uye maitiro ekutevedzera akafanana kune ese eBrazil zvigadzirwa zvemumba nekune dzimwe nyika. Kana zvigadzirwa zvichishanda kune zvinomanikidzirwa certification, mhedzisiro yekuyedza uye mushumo zvinofanirwa kuenderana nemirairo nemirairo yakatemwa sekukumbirwa neANATEL. Chigadzirwa chitupa chichapihwa neANATEL kutanga chigadzirwa chisati chatenderedzwa mukushambadzira uye kuiswa mukushandisa.
▍Ndiani ane mhosva ye ANATEL Homologation?
Masangano ehurumende yeBrazil akajairwa, mamwe masangano anozivikanwa echitupa nemalebhu ekuyedza ndeye ANATEL certification chiremera chekuongorora nzira yekugadzira yekugadzira unit, senge chigadzirwa dhizaini maitiro, kutenga, kugadzira maitiro, mushure mebasa uye zvichingodaro kuti uone kuti chigadzirwa chemuviri chinoteererwa. neBrazil standard. Mugadziri achapa magwaro uye masampuli ekuyedza uye kuongorora.
▍ Neiko MCM?
● MCM ine 10 makore ane ruzivo rwakawanda uye zviwanikwa mukuyedza uye certification indasitiri: yemhando yepamusoro sevhisi sisitimu, yakadzama inokwanisa timu yehunyanzvi, inokurumidza uye yakapusa certification nekuyedza mhinduro.
● MCM inodyidzana nemasangano akawanda epamusoro-soro emuno anozivikanwa zviri pamutemo achipa mhinduro dzakasiyana-siyana, sevhisi yechokwadi uye iri nyore kune vatengi.
Crush muyedzo wakajairwa kuona kuchengetedzeka kwemaseru, kutevedzera kudhumhana kwemaseru kana zvigadzirwa zvekupedzisira mukushandiswa kwemazuva ese. Pane kazhinji mhando mbiri dzekupwanya bvunzo: flat kupwanya uye chidimbu kupwanya. Kuenzaniswa neflat crush, iyo chidimbu indentation inokonzerwa ne spherical kana cylindrical indenter inowanzoita kuti sero risashande. Iyo inopinza iyo indenter, iyo yakanyanya kudzika kushushikana pane yakakosha chimiro che lithium bhatiri, zvakanyanya kuputika kwemukati musimboti, izvo zvinokonzeresa deformation uye kutamiswa kwepakati, uye zvinototungamira kune zvakakomba mhedzisiro senge electrolyte kuvuza kana. kunyange moto. Saka kupwanya kunotungamira sei pakusashanda kwesero? Pano kusuma iwe kushanduka kwemukati kwemukati mukati meiyo extrusion bvunzo yemunharaunda. Simba rinobva raendeswa mukati mebhatiri, uye gungano resero rinotangawo kukanganisa.
Nekumwe kudzvanywa kwemusoro wekupwanya, deformation iri kuwedzera uye nzvimbo inogadzirwa. Panguva imwecheteyo, nzvimbo yepakati pakati pega yega electrode layer inopfupiswa zvishoma nezvishoma. Pasi pekumanikidzwa kunoramba kuripo, muunganidzi wezvino akakotama uye akaremara, uye mabhendi ekugera anoumbwa. Kana iyo deformation ye electrode zvinhu inosvika painogumira, iyo electrode zvinhu inoburitsa kuputika.
Nekuwedzera kwe deformation, mutswe zvishoma nezvishoma unowedzera kumuunganidzi wezvino, uyo uchabvaruka uye kuburitsa ductile fracture. Uye zvakare, iyo radial crack yakarebeswa nekuda kwekuwedzera kwekushushikana uye radial displacement.
